0.5.28:

This patch release allows the enhanced target-ar logic that was

introduced in the previous patch release to properly work on legacy

systems with a tricky posix_spawnp() implementation.

- driver: enhanced target-ar logic: accommodate legacy systems.

0.5.27:

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.

0.5.26:

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().

0.5.25:

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.

0.5.24:

This patch release explicitly requests definition of AT_FDCWD via definition

of _POSIX_C_SOURCE in translation units that refer to it.

0.5.23:

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).

0.5.22:

This patch release explicitly requests the openat() interface via definition

of _POSIX_C_SOURCE in translation units that need it.

0.5.21:

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.

0.5.20:

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.

0.5.19:

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.

0.5.18:

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 initial -dlpreopen support.

- driver: support -thread-safe more elegantly.

- driver: properly handle -thread-safe (no-op, compatibility).

0.5.17:

This patch release fixes a subtle bug in the newly added support for

packages that depend on the reordering of linker arguments.

0.5.16:

This patch release fixes a subtle bug in slibtool-shared's

generation of dependency lists when creating convenience

library archives. Beginning with this release, the mesa

package can be built with slibtool in its entirety.

- slibtool-shared: properly handle .la arguments when creating an archive.

- slbt_exec_link_create_dep_file(): properly initialize and track fdeps.

0.5.15:

This patch release provides seamless support for the building of

packages which rely on the ordering of linker arguments. With

slibtool, reordering takes place only when deemed necessary.

- link mode: support packages that rely on argument reordering.

- error trace: remove and fix inadvertent calls to strerror(3).

0.5.14:

This patch release provides several fixes at the driver level, as well as

several improvements to slibtool's own internals. Addition of extended

variable support to slibtool's ./configure now makes it fully compatible

with (distro) build systems that pass those variable to ./configure by

default.

- link mode: fix fdepfile construction when determining dynlib dependency.

- link mode: static archives: always have ar(1) act as ranlib(1).

- driver: refine handling of --target.

- build system: added extended dir variables.

0.5.13:

This patch release ensures successful installation of a shared library with

which no accompanying static archive was created. The release also includes

two improvements in slibtool's own build system.

- link mode: create an archive /dev/null symlink placeholder as needed.

- PE soname support: added the designated LDFLAGS_SONAME variable.

- build system: configure: pass --sysroot to the linker as a compiler argument.

- install mode: respect -disable-static.

- legacy wrappers: implemented compatible library and objects wrappers.

- build system: added support for cygwin's, mingw's, and msys's semantics.

0.5.11:

This patch release provides -portbld- support for systems that still need

it, as well as an initial implementation of the --uninstall mode. In addition,

this release includes a few important bug fixes, as well as adds --source-dir

support to slibtool's own build system.

- driver: accommodate hosts that occasionally use '-portbld-' in their triple.

- link mode: properly handle -all-static when creating an executable image.

- link mode: add -L.libs for current-directory .la input arguments.

- uninstall mode: initial implementation.

This patch release fixes the following subtle link-mode bugs:

- link mode: archive creation: .la-associated objects are always under .libs/.

- link mode: soname: properly handle -module when output begins with dso prefix.

0.5.9:

This patch release enhances support of indirect dependencies, as well

the handling of direct invocation of executables (as opposed to passing

an executable to gdb or similar as an argument).

- execute mode: properly handle direct program invocation.

- link mode: account for directory depth when generating .deps for .la wrapper.

- link mode: properly handle sub-directories in indirect .la wrapper dependency.

- build system: Makefile: added custom header installation support.

0.5.2:

This patch release includes several fixes of bugs that were discovered while

testing slibtool as the primary libtool in a pkgsrc comprehensive build. In

addition, the release includes several improvements to slibtool's own build

system.

- link mode: legabits: generate a perfectly compatible wrapper.

- install mode: legabits: install a perfectly compatible wrapper.

- project: added compatibility symlinks (clibtool, clibtool-[shared|static])

- build system: removed the endian.h test.

- build system: proper use of any-os.mk.

0.5.0:

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.
