* pkg-infra: pass --disable-doc if documentation is not enabledArnout Vandecappelle2012-12-121-1/+9
| | | | | | | | | | | | | | | | Many configure scripts support an option like --disable-doc, --disable-docs or --disable-documentation. Pass all of these to configure. In addition, not all Xorg packages accept the --disable-xxx. Instead they look for xmlto and/or fop and build documentation if they exist. For host packages, this may lead to build errors because /usr/bin/xmlto uses libxml2 and we set LD_LIBRARY_PATH to point to $(HOST_DIR)/lib, which may contain a libxml2 as well. So it's essential to disable xmlto for host packages. Also some whitespace cleanup.

* pkg-infra: make sure cross compiling is enabled when host == targetArnout Vandecappelle2012-10-041-1/+1
| | | | | | | | | | | | | | | | When compiling for the same architecture and libc as the host, GNU_TARGET_NAME and GNU_HOST_NAME are equal. configure scripts use these to detect cross-compilation, and will decide that we're doing native compilation. This may trigger running of executables, which fail because of missing libraries in the host environment. To solve this, set the vendor part in GNU_TARGET_NAME to buildroot. This problem exists for instance in xserver_xorg-server on x86_64.

| | | | | | | | | | | -mno-abicalls is an old kludge for some (probably) old issue.

* Clarify MIPS ABIs supportThomas Petazzoni2012-09-041-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Practically speaking, MIPS has three useful ABIs: * o32 is for 32-bits CPUs, or 64-bit CPUs running only a 32-bit subset of the instruction set. * n32 is for 64-bits CPUs only. It has 32-bits pointers and long integers. * n64 is for 64-bits CPUs only. It has 64-bits pointers and long integers. See http://www.linux-mips.org/wiki/MIPS_ABI_History and http://www.linux-mips.org/wiki/WhatsWrongWithO32N32N64 for more details. So, this commit reworks the Buildroot MIPS support by: * Add separate mips64/mips64el top-level architectures. * Renaming the n32 ABI option to BR2_MIPS_NABI32, for consistency with BR2_MIPS_OABI32. * Renaming the n64 ABI option to BR2_MIPS_NABI64, for consistency with BR2_MIPS_OABI32. * Make the n32 and n64 ABI selections select the BR2_ARCH_IS_64, since those ABIs are valid on 64-bits CPUs only. * Removing the o64 ABI, which is practicaly never used. * Removing the "none" ABI, which really doesn't make sense. * Introduce the mips64 and mips64el architecture names when a 64-bits MIPS ABI is choosen. This will fix build issue like http://autobuild.buildroot.org/results/9b8c5ea86c953a89e85e7b67e9221de41773f652/build-end.log where gmp was confused by the fact of having a 32 bits architecture (detected by the mips- architecture part of the tuple) but 64 bits integer size when compiling. * Adjust the uclibc.mk logic to support the new mips64/mips64el architecture names, and take into account the renaming of the ABI options. This has been build tested by generating Buildroot toolchains and compiling a few packages for MIPS o32, MIPS n32 and MIPS n64. This work is originally based on prior work done by Gustavo Zacarias.

* Remove -fPIC on x86_64Arnout Vandecappelle (Essensium/Mind)2012-07-131-6/+0
| | | | | | | | | | | | | | | | The -fPIC breaks the purgatory of kexec (= the code that passes command-line arguments to the kernel): kexec doesn't know how to handle the GOT and PLT relocation entries. There is also no reason at all to pass -fPIC. Shared libraries that require it will add it to their local Makefiles, and normal executables have no business with -fPIC (plus it adds overhead...). The -fPIC was added by Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> in commit 8027784c. That commit adds sysroot parameters to CFLAGS. There is no explanation why -fPIC is also added for x86_64.

However, we are going to allow "0" to be a meaningful value for BR2_JLEVEL, which won't work for these uses. Given that it is not permissible to modify BR2_-prefixed variables in Makefiles, we need an intermediate variable. Define PARALLEL_JOBS to $(BR2_JLEVEL), and use the former in MAKE's definition.

* package: set PKG_CONFIG_SYSROOT_DIR in HOST_MAKE_ENVSven Neumann2012-04-151-0/+1
| | | | | | | | | | | | | | | | | A host package that uses AUTORECONF (such as host-libglib2) may end up running './config.status --recheck'. This will call the configure script with the environment variables set in HOST_MAKE_ENV. If PKG_CONFIG_SYSROOT_DIR is missing this will cause the hardcoded sysroot dir take effect leading to wrong paths. See commit 22acade2ec311 which works around this problem by fiddling with the generated .pc file. This commit becomes obsolete with this fix.

This is mandatory for e500v1/v2 cores since they don't support classic FPU mode as the e500mc does. Useful for Freescale's PowerQUICC III and single/dual-core QorIQ line of processors.

We enable static libraries since they can still be useful to statically link applications against some libraries (sometimes it is useful for size reasons). Static libraries are anyway only installed in the STAGING_DIR, so it doesn't increase in any way the size of the TARGET_DIR. For host packages, always pass --enable-shared and --disable-static.

| | | | | | | | | | | | | | | | Add a simple toolchain wrapper for external toolchains, which forces the correct sysroot/march/mtune/floating point options needed to use it with buildroot. With this in place the external toolchain behaves similar to the internal ones, and the special handling can be removed. This also means that the toolchain is usable outside buildroot without having to pass any special compiler flags. Also adjust the downloadable external toolchain support to install under HOST_DIR so it can be used after the temporary build files are removed. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

| | | | | | | | | | | | | | | Commit 7e3e8ec040b (CFLAGS/LDFLAGS: don't add -I / -L args for STAGING_DIR) exposed a lingering libtool problem. Unless instructed otherwise (using -L) libtool will search its built in system path for libraries, and use those instead if found. The default search path is '/usr/lib, /lib, /usr/local/lib', which is no good for cross compilation. Fix it by setting the system search path to the empty string, effectively disabling this feature.

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.).
