0.5.28:
5be89b
5be89b
This patch release allows the enhanced target-ar logic that was
5be89b
introduced in the previous patch release to properly work on legacy
5be89b
systems with a tricky posix_spawnp() implementation.
5be89b
5be89b
- driver: enhanced target-ar logic: accommodate legacy systems.

0.5.27:
4c6c6b
4c6c6b
This patch release provides an important enhancement with respect to the
4c6c6b
identification of the ar tool to be invoked in slibtool's link mode. More
4c6c6b
specifically, rather than relying on the presence of <target>-ar, slibtool
4c6c6b
will now attempt to invoke, as needed, several alternate ar tools in the
4c6c6b
following order: <target>-ar, <target>-<compiler>-ar, and, in the case
4c6c6b
of the native target, also <compiler>-ar and ar.
4c6c6b
4c6c6b
- driver: slbt_init_host_params(): enhance the target-ar related logic.

bcd1d3
0.5.26:
bcd1d3
bcd1d3
This patch release follows significant improvements in, as well as additions
bcd1d3
to slibtool's functionality. Most notably, with the additions of --heuristics
bcd1d3
and the rlibtool convenience symlink, slibtool may now automagically operate
bcd1d3
in the exact same mode (static only, shared only, or both) as the generated
bcd1d3
libtool script for which it serves as a surrogate.
bcd1d3
bcd1d3
- utility: --heuristics support: added the 'rlibtool' convenience symlink.
bcd1d3
- utility: convenience symlinks: added rclibtool, rdlibtool, and rdclibtool.
bcd1d3
- link mode: properly handle local archives.
bcd1d3
- link mode: remove placeholder arguments.
bcd1d3
- link mode: remove redundant -l arguments.
bcd1d3
- link mode: remove redundant -L arguments.
bcd1d3

bcd1d3
- driver: execution context: added slbt_reset_argvector().
bcd1d3
- driver: properly normalize --library-path=<path> arguments.
bcd1d3
- internals: slbt_mkdir() now uses the context's fdcwd.
bcd1d3
- internals: slbt_adjust_linker_argument() now uses the context's fdcwd.
bcd1d3
- internals: -shared/-static heuristics: added slbt_get_lconf_flags().

6de262
0.5.25:
6de262
6de262
This patch release follows several important enhancements in slibtool's
6de262
functionality, including proper support of explicit .a and .so input
6de262
arguments in link mode, and use of validly alternate (non-)pic objects.
6de262
With respect to compiler and target flavors, slibtool now accommodates
6de262
clang's debated approach towards the -fPIC switch in always-pic targets.
6de262
Last but not least, and following much discussion and consideration of
6de262
the various trade-offs, this release redefines _XOPEN_SOURCE to 700. With
6de262
that said, slibtool could still be easily built on older systems for as
6de262
long as they provide openat, faccessat, and (the soon-to-be-used) fexecve.
6de262
6de262
- driver: added --tag=RC support.
6de262
- driver: added --windres support.
6de262
- driver: use a compiler --target argument also as a tool argument.
6de262
- driver: if no --tag had been defined in compile mode, set --tag to CC.
6de262
- link mode: properly handle explicit archive input arguments.
6de262
- link mode: properly handle external archives and libraries.
6de262
- link mode: process dependencies also for non-pic .la args.
6de262
- link mode: support validly alternate (non-)pic objects.
6de262
- target flavors: accommodate conceptually challenged, PICky targets.
6de262
- target flavors: flavor detection: associate -windows- with mingw.
6de262
- target flavors: further eliminate compiler -dumpmachine invocations.

0.5.23:
0f1753
0f1753
This patch releases fixes a couple of minor issues in slibtool's own build
0f1753
system.
0f1753
0f1753
build system: all-shared front-end variant: fix ordering of -l$(PACKAGE).

0343bc
0.5.21:
0343bc
0343bc
This patch release follows important enhancements in slibtool's library
0343bc
interfaces and API contract. In particular, slibtool now no longer uses
0343bc
streams, but rather pure file descriptors. In addition, i/o operations
0343bc
now robustly handle interruption by signals, and thus do not depend on
0343bc
the underlying system calls being restartable. Last but not least,
0343bc
slibtool now installs a pkgconfig configuration file when applicable.
0343bc
0343bc
- argv.h: output usage and errors using [argv_]dprintf rather than fprint.
0343bc
- argv.h: argv_get(): be consistent between forward decl. and impl.
0343bc
- argv.h: move definition of struct argv_meta_impl to the implementation block.
0343bc
- internals: added slbt_mapped_readline().
0343bc
- internals: added slbt_map_file(), slbt_unmap_file().
0343bc
- internals: added slbt_dprintf(), a signal-resilient dprintf implementation.
0343bc
- driver: argv usage and error output: use the signal-resilient slbt_dprintf().
0343bc
- driver: support alternate fd's for input/output/error/log.
0343bc
- driver: slbt_init_host_params(): propagate failure of <compiler> -dumpmachine.
0343bc
- driver: slbt_init_host_params(): do not set fnative when !fdumpmachine.
0343bc
- driver: struct slbt_fd_ctx: added .fdcwd and .fddst.
0343bc
- library: invocations of openat() now use the context's fdcwd.
0343bc
- project: added initial pkgconfig support.
0343bc

0.5.20:
17c199
17c199
This patch release includes several important bug fixes pertaining to both
17c199
the link and compile mode, as well as the addition of a compatible --features
17c199
output.
17c199
17c199
- driver: added slbt_output_features(), providing compatible --features output.
17c199
- driver: compatibility: have -{shared|static} imply -disable-{static|shared}.
17c199
- link mode: properly handle the combination of -release and -version-info.
17c199
- link mode: slbt_exec_link_create_dep_file(): record top-level -L arguments.

0d2823
This patch release includes several important fixes to the link mode
0d2823
and driver logic. In addition, it adds mdso support to midipix targets,
0d2823
as well as updates slibtool's own build system.
0d2823

799329
799329
This patch release fixes a subtle bug in slibtool-shared's
799329
generation of dependency lists when creating convenience
799329
library archives. Beginning with this release, the mesa

0.5.14:
d1c2e6
d1c2e6
This patch release provides several fixes at the driver level, as well as
d1c2e6
several improvements to slibtool's own internals. Addition of extended
d1c2e6
variable support to slibtool's ./configure now makes it fully compatible
d1c2e6
with (distro) build systems that pass those variable to ./configure by
d1c2e6
default.
d1c2e6
d1c2e6
- link mode: fix fdepfile construction when determining dynlib dependency.
d1c2e6
- link mode: static archives: always have ar(1) act as ranlib(1).

8f07c5
0.5.9:
8f07c5
8f07c5
This patch release enhances support of indirect dependencies, as well
8f07c5
the handling of direct invocation of executables (as opposed to passing

0.5.0:
77a4b7
77a4b7
This is the first tagged release of slibtool. It is the result of two months of
77a4b7
intensive development, and follows rigorous testing on several systems. As of
77a4b7
this initial release, slibtool is known to successfully build an entire Exherbo
77a4b7
Linux system from source, build the midipix cross compilation toolchain from
77a4b7
source, and likewise build many other packages.
77a4b7
77a4b7
Support for the ELF/default host flavor is complete, and does not appear to have
77a4b7
any errors. Support for the PE/midipix flavor is also complete, and includes not
77a4b7
only static archives and shared libraries, but also import libraries with
77a4b7
version support. Support for the Darwin host flavor already exists too, yet it
77a4b7
is currently semantically incorrect, and so will be fixed in the next release.
