2014-10-29Build: Prepare to support Automake's subdir-objects.Lasse Collin1-4/+4
Due to a bug in Automake, subdir-objects won't be enabled for now. http://debbugs.gnu.org/cgi/bugreport.cgi?bug=17354 Thanks to Daniel Richard G. for the original patches.
2014-04-25Build: Fix the combination of --disable-xzdec --enable-lzmadec.Lasse Collin1-1/+9
In this case "make install" could fail if the man page directory didn't already exist at the destination. If it did exist, a dangling symlink was created there. Now the link is omitted instead. This isn't the best fix but it's better than the old behavior.
2010-10-08Build: Add options to disable individual command line tools.Lasse Collin1-2/+10
2010-10-05Build: Remove the static/dynamic tricks.Lasse Collin1-3/+1
Most distros want xz linked against shared liblzma, so it doesn't help much to require --enable-dynamic for that. Those who want to avoid PIC on x86-32 to get better performance, can still do it e.g. by using --disable-shared to compile xz and then another pass to compile shared liblzma. Part of these static/dynamic tricks were needed for Windows in the past. Nowadays we rely on GCC and binutils to do the right thing with auto-import. If the Autotooled build system needs to support some other toolchain on Windows in the future, this may need some rethinking.
2009-11-15Add lzma_physmem().Lasse Collin1-4/+2
I had hoped to keep liblzma as purely a compression library as possible (e.g. file I/O will go into a different library), but it seems that applications linking agaisnt liblzma need some way to determine the memory usage limit, and knowing the amount of RAM is one reasonable way to help making such decisions. Thanks to Jonathan Nieder for the original patch.
2009-09-19Various changes.Lasse Collin1-2/+11
Separate a few reusable components from XZ Utils specific code. The reusable code is now in "tuklib" modules. A few more could be separated still, e.g. bswap.h. Fix some bugs in lzmainfo. Fix physmem and cpucores code on OS/2. Thanks to Elbert Pol for help. Add OpenVMS support into physmem. Add a few #ifdefs to ease building XZ Utils on OpenVMS. Thanks to Jouk Jansen for the original patch.
2009-07-06Use sed instead of $(SED) so that we don't need toLasse Collin1-3/+3
use AC_PROG_SED. We don't do anything fancy with sed, so this should work OK. libtool 2.2 sets SED but 1.5 doesn't, so $(SED) happened to work when using libtool 2.2.
2009-06-30Build system fixesLasse Collin1-1/+19
Don't use libtool convenience libraries to avoid recently discovered long-standing subtle but somewhat severe bugs in libtool (at least 1.5.22 and 2.2.6 are affected). It was found when porting XZ Utils to Windows <http://lists.gnu.org/archive/html/libtool/2009-06/msg00070.html> but the problem is significant also e.g. on GNU/Linux. Unless --disable-shared is passed to configure, static library built from a set of convenience libraries will contain PIC objects. That is, while libtool builds non-PIC objects too, only PIC objects will be used from the convenience libraries. On 32-bit x86 (tested on mobile XP2400+), using PIC instead of non-PIC makes the decompressor 10 % slower with the default CFLAGS. So while xz was linked against static liblzma by default, it got the slower PIC objects unless --disable-shared was used. I tend develop and benchmark with --disable-shared due to faster build time, so I hadn't noticed the problem in benchmarks earlier. This commit also adds support for building Windows resources into liblzma and executables.
2009-06-27Create correct symlinks even whenLasse Collin1-3/+6
--program-{prefix,suffix,transform} is passed to configure.
2009-06-26Fix @variables@ to $(variables) in Makefile.am files.Lasse Collin1-9/+10
Fix the ordering of libgnu.a and LTLIBINTL on the linker command line and added missing LTLIBINTL to tests/Makefile.am.
2009-06-04Added xzdec man page.Lasse Collin1-0/+11
2009-04-13Put the interesting parts of XZ Utils into the public domain.Lasse Collin1-10/+3
Some minor documentation cleanups were made at the same time.
2009-02-07Make it easy to choose if command line tools should beLasse Collin1-2/+3
linked statically or dynamically against liblzma. The default is still to use static liblzma, but it can now be changed by passing --enable-dynamic to configure. Thanks to Mike Frysinger for the original patch. Fixed a few minor bugs in configure.ac.
2008-11-20Build xzdec and lzmadec from xzdec.c. xzdec supports only .xzLasse Collin1-1/+6
files and lzmadec only .lzma files.
2008-11-19Renamed lzma to xz and lzmadec to xzdec. We create symlinksLasse Collin1-6/+6
lzma, unlzma, and lzcat in "make install" for backwards compatibility with LZMA Utils 4.32.x; I'm not sure if this should be the default though.
2007-12-11Get rid of no-NLS gnulib. I don't know how to get itLasse Collin1-1/+3
working with Automake. People who want smaller lzmadec should use --disable-nls on non-GNU systems.
