vala: do not append a -dirty suffix to the valac version number

2012-05-18T16:45:37Z

When vala is built inside a Git repository with uncommitted changes, the valac version number has -dirty appended. This creates problems for packages (e.g. Midori) which require a valac version number without the -dirty suffix. Signed-off-by: Simon Dawson Signed-off-by: Peter Korsgaard

ccache: allow dynamic selection of cache directory

2012-05-18T08:42:29Z

The existing ccache infrastructure sets the cache directory hardcoded in the ccache binary. As this directory was set to ~/.buildroot-ccache, the cache is not necessarily local (e.g. in corporate environments the home directories may be mounted over NFS.) Previous versions of buildroot did allow to set the cache directory, but this was also hardcoded (so you had to rebuild ccache to change it), plus that support was removed. See http://lists.busybox.net/pipermail/buildroot/2011-July/044511.html for a discussion on this. This patch modifies ccache to respect a new shell variable (exported from the Makefile, based on a configuration option) instead of CCACHE_DIR. The name CCACHE_DIR itself is already used by autotargets for the ccache package. Signed-off-by: Thomas De Schampheleire Signed-off-by: Peter Korsgaard

socat: disable documentation build/installation

2012-05-17T21:43:43Z

The documentation generation process requires a special yold2man program, for which we don't have a package in Buildroot. Since we generally don't care much about documentation of packages, just adjust the package Makefile.in to not build/install its documentation.

socat: fix build failure due to ext2_fs.h header, bump version

2012-05-17T21:43:00Z

In kernel >= 3.3, the ext2_fs.h can no longer be imported from userspace. This has been fixed for internal toolchains by adding a patch to kernel headers, but this doesn't work with toolchains generated by Crosstool-NG, or potentially upcoming external toolchains. socat in fact has a test in its configure.in, but the configure was generated too long ago, and the generated test relies on the preprocessor result and not the compiler result (but warns that in the future, the compiler result will be used instead of the preprocessor result). So, by running autoconf on this package, we fix the problem: it properly checks whether ext2_fs is usable or not, and acts accordingly. Of course, it means that with recent versions of the kernel, ext2-specific features of socat are unavailable, and we'll have to wait for the socat developers to adapt their code so that they use the e2fsprogs headers. We also bump the version, since a new minor version fixing a security problem has been released. Signed-off-by: Thomas Petazzoni Signed-off-by: Peter Korsgaard

apr: requires shared library support

2012-05-17T21:42:26Z

The apr library requires shared library support unconditionally, so make it depend on !BR2_PREFER_STATIC_LIB, so that architectures that support static libraries only do not make this package available.

opencv: add zlib dependency

2012-05-17T19:00:16Z

The opencv package selects zlib, but it does not depend on it. This leads to cases where opencv gets built before zlib, and in this case, opencv uses its internal version of zlib, which doesn't build properly (it has some conditional code for ARM that is probably broken), see: http://autobuild.buildroot.org/results/45f4e195fe0cc5acace10287f5ff33aa953d5430/build-end.log We fix this by properly adding the opencv dependency on zlib.

toolchain/crosstool-NG: disable decimal floats

2012-05-16T08:39:32Z

Decimal floats were introduced circa gcc-4.2 or -4.3, and requires the floating-point environement fenv.h in the C library. The uClibc .config file used by crosstool-NG to build uClibc is the same as used by the internal buildroot mechanism, and explcitly disables fenv support. The quick workaround is to simply disable decimal floats in all crosstool-NG config files. In the long run, it might be better to check this situation, and/or add code and/or options in crosstool-NG to handle this (but it is much more involved, and this workaround is sane).
