In addition, this release entails several enhancements and fixes in other areas. - slibtoolize: new execution mode, driver integration, and symlink. - slibtoolize: added a no-op, yet backward compatible ltmain.sh. - slibtoolize: auxiliary files: added slibtool.sh (optional wrapper). - driver: --mkvars: implementation and integration. - driver: --mkvars: special case the SLIBTOOL make variable. - driver: --heuristics: added slibtool.cfg prioritized support. - driver: detect slibtool.cfg in non-heuristics mode where applicable. - driver: slbt_output_raw_vector(): refactor and prettify. - host: derive as from ranlib as needed. - host: derive windres and dlltool from ranlib as needed. - host: detect a native build environment based on ar(1). - host: set native mode based on the detected ar(1) as needed. - host: cfgmeta: mark tools derived from ranlib as such. - util: PE/COFF: list is target neutral, process all syms. - util: properly set weak aliases of strong symbols. - ar: yaml output: initial implementation. - ar: internally bind the meta ctx to the archive ctx. - ar: sort the syminfo vector in a coff-aware manner. - ar: PE/COFF: properly set weak aliases of strong symbols. - ar: symbol mapfile: properly set strong aliases of weak symbols. - ar: symbol vector: include weak aliases of strong symbols. - ar: symbol file: include weak aliases of strong symbols.

This (pinky promise, for real now) absolutely final patch release in the 0.5.x entails a large number of semantic fixes, several bug fixes, and also the entirely new slibtool-ar execution mode. We would still like to consider it a patch release since much of the above was needed for slibtool to correctly act as a gnu libtool drop-in replacement. As of this patch release, slibtool can be used with virtually all packages covered by a common Gentoo world build (as tested by @orbea, consisting of more than 900 packages and pending some fixes of incorrect usage bugs that were exposed by slibtool and filed with the respective upstream projects). Then again, slibtool continues to successfully build all packages included in a typical Midipix distro build, as well as all other packages that we have been able to test. Due to the large number of commits between the previous patch release and this one, only the most significant changes are listed below. - ar api: new in-memory archiver backend (parse & merge). - ar mode: new execution mode: archiver front-end. - driver: heuristics: support argv of ar, nm, dlltool, etc. - driver: correct precedence of heuristics-derived flag bits. - driver: added --info mode. - driver: corrected --config mode to be backward compatible. - compile mode: added --tag=ASM. - compile mode: properly handle custom compiler drivers. - compile mode: de-duplicate header search directory arguments. - link mode: general overhaul and refactoring of the code. - link mode: correct object selection with -static and -shared. - link mode: enhanced, tracebale dependency files. - link mode: support -export-symbols and -export-symbols-regex. - link mode: support -dlopen and -dlpreopen (self, force, libfoo). - link mode: handle convenience libraries using correct semantics. - link mode: cygwin & mingw support: enhanced dlltool semantics. - link mode: darwin support: implemented additional special cases. - execute mode: send informational output to stderr. - execute mode: reimplemented with well-formed semantics. - install mode: refactor, properly handle .so placeholder symlinks. - install mode: enhanced logging of file operation errors. - library: refactored, introduced secondary interface name-spaces. - library: utilize the visibility attribute on non-PE targets.

This post-last patch release in the 0.5.x series includes fixes to bugs that were discovered since release 0.5.34. In addition, this release introduces several new features in slibtool's driver, as well as some minor improvements in the implementation of existing program functionality. - driver: properly handle --help after --mode. - driver: handle --version as only (repeated) argument more elegantly. - driver: modify the cfgnmachine string for accuracy (-dumpmachine or --cchost). - driver: added --dumpmachine support. - driver: added -weak support, currently a no-op. - driver: added -objectlist support. - driver: -version-info suport: strictly verify the version info argument. - helper: added slbt_map_input(), slbt_unmap_input().

This is the last patch release in the 0.5.x series. As of this release, there are no known problems pertaining to slibtool's core functionality or compatibility with the historic libtool implementation. Outstanding features that are not covered by this release are the internal implementation of archive merging (as opposed to using ar(1) and MRI scripts), as well as the internal implementation, integration, and support of -dlpreopen. Included with this release is also m4/slibtool.m4, which by now has been tested against, and may be successfully used with legacy autoconf versions (such as 2.64), as well as more recent ones (2.69 or later). A new invocation mode, --mode=slibtoolize (or the slibtoolize symlink) is currently under development, and will be included with the next release. - driver: slbt_get_driver_ctx(): properly record the envp parameter. - driver api: slbt_get_flavor_settings(): initial implementation. - driver: added explicit --sysroot support. - link mode: set the -soname linker flag alongside the -avoid-version argument. - link mode: slbt_exec_link_create_executable(): enclose $DL_PATH in quotes. - link mode: slbt_exec_link_create_executable(): replace backtick with $(). - link mode: -module without -rpath is an executable, not a dynamic library. - link mode: legacy libtool compatibility: support linking against -module libs. - link mode: slbt_exec_link(): properly support non-default shared-object suffix. - link mode: slbt_exec_link_create_archive(): eliminate the libfoo.a symlink. - link mode: static-only libfoo.la: account for non-default shared-object suffix. - link mode: always create libfoo.so.def.{host|flavor} and related tags. - link mode: PE targets: -release: fix names used for and in import libraries. - link mode: slbt_exec_link_create_executable(): place .exe.wrapper under .libs/. - install mode: driver: added (referential) --sysroot support. - install mode: slbt_exec_install_entry: properly handle fussix flavors. - install mode: libfoo.la and ibfoo.so.def.host: properly handle -release. - install mode: slbt_exec_install_entry(): remove dead code. - install mode: libfoo.la installation: early detect static-only operation mode. - uninstall mode: driver: added (referential) --sysroot support. - heuristics: slbt_get_lconf_flags(): added missing 'else' in if-then block. - heuristics: slbt_get_lconf_flags(): enhanced the string-scanning logic. - library: replace all uses of open() with openat(). - library: replace all uses of chmod() with fchmodat(). - library: replace all uses of unlink() with unlinkat(). - library: replace all uses of rmdir() with unlinkat(). - library: replace all uses of rename() with renameat(). - library: replace all uses of symlink() with symlinkat(). - library: replace all uses of [slbt_]readlink() with [slbt_]readlinkat(). - library: replace all uses of stat() and lstat() with fstatat() counterparts. - library: replace all uses of getcwd() with slbt_realpath(). - library: eliminate use of the external environ variable.

This patch release fixes sed usage ('\s' vs '[[:space:]]') in slibtool's own build system. Release immediately in order to prevent build errors in strict build environments. - build system: ccenv_output_defs(): use conformant sed construct.

This patch release provides a few important additions and bug fixes, as well as several improvements in slibtool's own build system. In addition, it denotes the (semantic) transition from midipix.org to foss21.org. - driver: added F77 support. - driver: added -XCClinker support. - driver: added FC support. - driver: host flavors: added suffixed suffixes support. - driver: --heuristics: respect explicit --disable-shared and/or -static. - driver: resolve conflicting and/or incompatible command-line arguments. - driver, link mode: properly implement the -module semantics. - driver, compile & link mode: support arbitrary & known compiler wrappers. - link mode: host flavors: properly support suffixed suffixes. - install mode: host flavors: properly support suffixed suffixes.

This patch release provides an important enhancement with respect to the identification of the ar tool to be invoked in slibtool's link mode. More specifically, rather than relying on the presence of <target>-ar, slibtool will now attempt to invoke, as needed, several alternate ar tools in the following order: <target>-ar, <target>-<compiler>-ar, and, in the case of the native target, also <compiler>-ar and ar. - driver: slbt_init_host_params(): enhance the target-ar related logic.

This patch release follows significant improvements in, as well as additions to slibtool's functionality. Most notably, with the additions of --heuristics and the rlibtool convenience symlink, slibtool may now automagically operate in the exact same mode (static only, shared only, or both) as the generated libtool script for which it serves as a surrogate. - utility: --heuristics support: added the 'rlibtool' convenience symlink. - utility: convenience symlinks: added rclibtool, rdlibtool, and rdclibtool. - link mode: properly handle local archives. - link mode: remove placeholder arguments. - link mode: remove redundant -l arguments. - link mode: remove redundant -L arguments. - compile mode: remove placeholder arguments. - driver: added --heuristics support. - driver: slbt_get_driver_ctx(): support stack-based argv. - driver: output error vector upon post-argv-parsing failures. - driver: execution context: added slbt_reset_argvector(). - driver: properly normalize --library-path=<path> arguments. - internals: slbt_mkdir() now uses the context's fdcwd. - internals: slbt_adjust_linker_argument() now uses the context's fdcwd. - internals: -shared/-static heuristics: added slbt_get_lconf_flags().

This patch release follows several important enhancements in slibtool's functionality, including proper support of explicit .a and .so input arguments in link mode, and use of validly alternate (non-)pic objects. With respect to compiler and target flavors, slibtool now accommodates clang's debated approach towards the -fPIC switch in always-pic targets. Last but not least, and following much discussion and consideration of the various trade-offs, this release redefines _XOPEN_SOURCE to 700. With that said, slibtool could still be easily built on older systems for as long as they provide openat, faccessat, and (the soon-to-be-used) fexecve. - driver: added --tag=RC support. - driver: added --windres support. - driver: use a compiler --target argument also as a tool argument. - driver: if no --tag had been defined in compile mode, set --tag to CC. - link mode: properly handle explicit archive input arguments. - link mode: properly handle external archives and libraries. - link mode: process dependencies also for non-pic .la args. - link mode: support validly alternate (non-)pic objects. - target flavors: accommodate conceptually challenged, PICky targets. - target flavors: flavor detection: associate -windows- with mingw. - target flavors: further eliminate compiler -dumpmachine invocations.

This patch releases fixes a couple of minor issues in slibtool's own build system. build system: all-shared front-end variant: fix ordering of -l$(PACKAGE). build system: all-shared binary: added missing build-dep on $(SHARED_SOLINK).

This patch release explicitly requests the openat() interface via definition of _POSIX_C_SOURCE in translation units that need it.

This patch release follows important enhancements in slibtool's library interfaces and API contract. In particular, slibtool now no longer uses streams, but rather pure file descriptors. In addition, i/o operations now robustly handle interruption by signals, and thus do not depend on the underlying system calls being restartable. Last but not least, slibtool now installs a pkgconfig configuration file when applicable. - argv.h: output usage and errors using [argv_]dprintf rather than fprint. - argv.h: argv_get(): be consistent between forward decl. and impl. - argv.h: move definition of struct argv_meta_impl to the implementation block. - internals: added slbt_mapped_readline(). - internals: added slbt_map_file(), slbt_unmap_file(). - internals: added slbt_dprintf(), a signal-resilient dprintf implementation. - driver: argv usage and error output: use the signal-resilient slbt_dprintf(). - driver: support alternate fd's for input/output/error/log. - driver: slbt_init_host_params(): propagate failure of <compiler> -dumpmachine. - driver: slbt_init_host_params(): do not set fnative when !fdumpmachine. - driver: struct slbt_fd_ctx: added .fdcwd and .fddst. - library: invocations of openat() now use the context's fdcwd. - project: added initial pkgconfig support.

This patch release includes several important bug fixes pertaining to both the link and compile mode, as well as the addition of a compatible --features output. - driver: added slbt_output_features(), providing compatible --features output. - driver: compatibility: have -{shared|static} imply -disable-{static|shared}. - link mode: properly handle the combination of -release and -version-info. - link mode: slbt_exec_link_create_dep_file(): record top-level -L arguments. - link mode: --disable-{shared|static}: use differently-named placeholders.

This patch release includes several improvements in the driver logic, as well as one important fix to the compile mode logic. - driver: support -export-dynamic. - driver: allow flavor-based use of native tools (ar,ranlib,etc.) - driver: slbt_init_host_params(): improve native target detection logic. - driver: -shrext support: only use the extension portion of the extension. - compile mode: gnu libtool compatibility: do not add -c to compiler arguments.

This patch release includes several important fixes to the link mode and driver logic. In addition, it adds mdso support to midipix targets, as well as updates slibtool's own build system. - link mode: re-implemented slbt_exec_link_finalize_argument_vector(). - link mode: import library generation: added mdso support. - link mode: use -fpic objects with -disable-static. - driver: added --mdso and --implib support. - driver: added initial -dlpreopen support. - driver: support -thread-safe more elegantly. - driver: properly handle -thread-safe (no-op, compatibility).

This patch release fixes a subtle bug in the newly added support for packages that depend on the reordering of linker arguments.

This is the first tagged release of slibtool. It is the result of two months of intensive development, and follows rigorous testing on several systems. As of this initial release, slibtool is known to successfully build an entire Exherbo Linux system from source, build the midipix cross compilation toolchain from source, and likewise build many other packages. Support for the ELF/default host flavor is complete, and does not appear to have any errors. Support for the PE/midipix flavor is also complete, and includes not only static archives and shared libraries, but also import libraries with version support. Support for the Darwin host flavor already exists too, yet it is currently semantically incorrect, and so will be fixed in the next release.
