2012-01-15gcc-uclibc-4.x.mk: get rid of BR2_DEPENDS_DIRPeter Korsgaard
Now that we have dropped the make-write-deps patch. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2012-01-12Remove java supportPeter Korsgaard
Has been marked as broken since July 2010 (39e6ba1b), and nobody has stepped up to support it, so now finally remove it completely. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2011-09-17support: move package/gnuconfig to support/gnuconfigThomas Petazzoni
The CONFIG_UPDATE macro is no longer defined in package/gnuconfig/gnuconfig.mk, but instead in package/Makefile.autotools.in. It it also changed a little bit to take the directory of the package sources as argument, and the AUTOTARGETS infrastructure is updated to use this macro.

2011-09-17support: move patch-kernel.sh and rename itThomas Petazzoni
The name "patch-kernel.sh" is a bit stupid, since this script is used to patch everything in Buildroot, not only kernel trees. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

The arm-softfloat.patch.conditional patches are no longer in Buildroot since 9af188d883b2657bd967e6621011d4bbe1bb3441 (October 2009), which removed support for gcc 3.x and 4.0.x. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2011-05-02toolchain/gcc: add openmp support optionGustavo Zacarias
Add OpenMP support in gcc as an option instead of dynamically enabling it when threads are present. Also fix it up since we never installed libgomp to the target or staging thus it was never really functional.

2011-02-10target gcc: fix recompilation issueGustavo Zacarias
gcc_target wants uclibc_target which is now first stage uclibc (not real, from the NPTL build stage addition). This triggers gcc-final to be rebuilt (albeit cached) and reinstalled, thus touching all the stamps around and triggering a rebuild of gcc_target. Switch to $(STAMP_DIR)/gcc_libs_target_installed instead so that we only depend on the last stage of cross gcc being installed to rebuild.

2011-01-19toolchain: only fetch gcc/gmp/mpfr/mpc when using a buildroot toolchainGustavo Zacarias
Closes #3103 gcc/gmp/mpfr/mpc are only needed when using an internal buildroot toolchain, so only add them to HOST_SOURCE then. Otherwise we get some nasty fetch error when doing "make source" [Peter: add gmpc/mpfr/mpc and reword commit text] Signed-off-by: Gustavo Zacarias <gustavo@zacarias.com.ar> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

2010-12-13toolchain: rework thread optionsThomas Petazzoni
The selection of linuxthreads, linuxthreads old or NPTL doesn't make a lot of sense for external toolchains. So, instead, we : * Introduce an hidden BR2_TOOLCHAIN_HAS_THREADS option, which must be selected by toolchain specific options when thread support is available. Package needing to test thread support should use this option. * Move the none/linuxthreads/linuxthreads old/NPTL selection to Buildroot internal toolchain configuration. * Add an option in external toolchain to tell if thread support is available or not in the external toolchain. We assume that glibc without threads is not possible, as Ulrich Drepper said in http://sourceware.org/ml/libc-alpha/2005-08/msg00091.html ffmpeg, dmalloc and openvpn are fixed to use the new BR2_TOOLCHAIN_HAS_THREADS option. For openvpn, --enable-threads=posix is no longer used, as the configure script doesn't even understand this option.

2010-12-13toolchain: rework C++ optionsThomas Petazzoni
Instead of having BR2_GCC_CROSS_CXX and BR2_INSTALL_LIBSTDCPP, with BR2_GCC_CROSS_CXX not being visible (and therefore being useless), let's just keep BR2_INSTALL_LIBSTDCPP to enable C++ in the toolchain and install C++ libraries on the target. We also take that opportunity to make BR2_INSTALL_LIBSTDCPP an hidden option, which is selected by an option in Buildroot toolchain support or an option in External toolchain support, just as we did for other toolchain features. Some work definitely remains to be done : - The name BR2_INSTALL_LIBSTDCPP is ugly, but we keep it for the moment in order to avoid changing all packages. - We should clarify the other language-related options (Fortran, Java, Objective-C, etc.).

2010-07-30toolchain: enforce --disable-multilibPeter Korsgaard
Since 5575d205c (toolchain: remove multilib) we were no longer passing --disable-multilib, which broke builds for multilib-capable archs (like x86-64, ppc, ..). Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-07-29Add support for uclibc NPTL toolchain.Khem Raj
This patch modifies current toolchain build sequence so that NPTL enabled toolchain can be built. The new sequence works well with linuxthreads as well. It introduces a new pass for gcc cross compilation. The new sequence is binutils->gcc-initial->linux-headers -> uclibc-configured (some cheats to generate phony shared libc.so and libm.o) -> gcc-intermediate(with shared lib support) -> uclibc -> gcc-final I also added a new sample config arm_nptl_toolchain_defconfig which builds the toolchain and busybox. I have only tried it on arm. However it should work for other architectures which support NPTL on uclibc e.g. mips, sh, x86, ppc, x86_64 Signed-off-by: Khem Raj <raj.khem@gmail.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
2010-07-28toolchain: remove multilibThomas Petazzoni
Supporting multilib is much more than just passing --enable-multilib to gcc. You have to actually build the C library several times (once for each multilib variant you want to support in your toolchain), and to pass MULTILIB_OPTIONS/MULTILIB_EXCEPTIONS values to gcc to let it know the set of multilib variants you're interested in. Since we'll probably never support multilib toolchains in Buildroot, just get rid of this BR2_ENABLE_MULTILIB option. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2010-07-28gcc: remove option on SJLJ exceptionsThomas Petazzoni
This is a very advanced option, and it seems, according to http://choices.cs.uiuc.edu/exceptions.pdf that SJLJ exceptions aren't really interesting. Users really interested by this can always use the BR2_EXTRA_GCC_CONFIG_OPTIONS is they want. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2010-07-27binutils,gcc: use correct --prefixThomas Petazzoni
The cross binutils and cross gcc are actually going to be executed from $(STAGING_DIR)/usr, so the correct prefix is $(STAGING_DIR)/usr and not /usr. This also fixes what is known as the "AVR32 toolchain build failure", which was due to the fact that the prefix directory wasn't writable (since it was /usr).

2010-07-27Create <tuple>/lib -> <sysroot>/lib symlink before installing cross gccThomas Petazzoni
This commit solves bug #1051. The problem in this bug in that WebKit compiles a sample C program, which uses WebKit. As WebKit is written in C++, even though the program it built with CROSS-gcc, it must be linked with libstdc++. However, CROSS-gcc can't find the libstdc++ has it's hidden inside <sysroot>/<tuple>/lib. Therefore, this commit creates a symbolic link <sysroot>/<tuple>/lib -> <sysroot>/lib before running the CROSS-gcc installation. While this may look like a hack, this is the solution used by both Crosstool-NG and OpenWRT. Moreover, with this symbolic link in place, I think bug #1741 may also be solved. The problem in this bug is that the linker tries to link against /lib/libc.so.0. This is due to the fact that the linker finds a libc.so script file in the original toolchain location and not inside the copy of the toolchain sysroot in $(STAGING_DIR). As the script file is found outside of the current toolchain sysroot, ld considers the script has non-sysrooted, and therefore doesn't prefix all paths found in the script file (such as /lib/libc.so.0) with the sysroot path, leading to the failure. So, in details, this commit : * Adds a BR2_ARCH_IS_64 invisible config knob that is used to know if the arch is a 64 bits architecture or not. * Creates the <sysroot>/<tuple>/lib -> <sysroot>/lib symbolic link, and the <sysroot>/<tuple>/lib64 -> <sysroot>/lib64 symbolic link if needed. * Fixes the external toolchain sysroot detection code so that the 'sed' replacement is done *after* the readlink -f evaluation. I have tested this by building ARM, x86 and x86_64 toolchains with Buildroot, and then use these toolchains as external toolchains to build a full X.org/Gtk/WebKit/Midori stack. I have also done a complete ARM Buildroot internal toolchain build with the same full X.org/Gtk/WebKit/Midori stack. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

2010-07-27target-gcc: remove useless copies of gccThomas Petazzoni

2010-02-25gmp/mpfr: make sure host builds add source targets to HOST_SOURCEPeter Korsgaard
Closes #1183. When gmp/mpfr is needed for the host (E.G. when using an internal toolchain), the host-lib{gmp,mpfr}-source targets weren't added to HOST_SOURCE, so make source / external-deps didn't handle them. Notice that we have the same issue with the new host package support, there we should probably use HOST_<package>_DEPENDENCIES for -source dependencies.

2010-02-25gcc on target: add missing definitions for gcc 4.4Thomas Petazzoni
Depending on the gcc version, the gcc include and lib directories have changed. We include support for gcc 4.4 by copy/pasting the support for gcc 4.3. Locations don't seem to have changed between 4.3 and 4.4. This allows the syslimits.h fixup to succeed. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>
2009-12-15gcc: do not pass --with-pkgversion to gcc < 4.3Thomas Petazzoni
Commit 09c181f2891276c458de327d241151bab38bde0f added new options passed to gcc configure to set --with-pkgversion and --with-bugurl, to gcc >= gcc 4.3. To check this, it was checking that the GCC_VERSION string does not contain 4.2. Unfortunately, the test is bogus. It does a findstring on x4.2. (with a final dot) but compares the result with x4.2 (without the final dot). The result is that even with 4.2 versions, the test was true, leading --with-pkgversion and --with-bugurl being passed to gcc's configure script.
