| | | | | | | | | The problem fixed by 60f945e47a15e10f0e777f69b05492b6f7ba918d is in fact not limited to the AVR32 architecture, as reported by Will Newton on the list.

* Detect early if an UTF-8 locale is neededThomas Petazzoni2010-08-112-0/+13
| | | | | | | | | | | Check in toolchain/dependencies/dependencies.sh if an UTF-8 locale is properly present on the system before trying to build a locale enabled toolchain. As this test is only needed when a locale enabled toolchain is going to be built, we pass the configuration file path to the dependencies.sh script so that it can grep for the current value of various options.

* Make uClibc gen_wc8bit shows an error when no locale support availableThomas Petazzoni2010-08-112-0/+34
| | | | | | | | | | | | | | | When no UTF-8 locale is available on the host system, uClibc can't generate some stuff it needs to compile a C library with locale support. Unfortunately, as gen_wc8bit message is shown on stdout and the stdout of gen_wc8bit is redirected to a file, the user don't see anything, as reported at http://lists.busybox.net/pipermail/buildroot/2010-May/034177.html. Those two patches fix the problem for uClibc 0.9.31 and 0.9.30.3.

|/ | | | | | | | | | | | | | | | | | | | 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>
* toolchain: remove multilibThomas Petazzoni2010-07-284-17/+1
| | | | | | | | | | | | | 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>

* toolchain: move makefile includesYann E. MORIN2010-07-282-0/+26
| | | | | | | | | | | | | | | | | | | Including a bunch of Makefiles with wildcard makes it impossible to add new toolchain backends. Avoid that by namely including needed files. The external toolchain still needs to include all the toolchain/*/*.mk sub-makefiles, as they are needed to build a toolchain that runs on the target. It is to be noted that the cross-toolchain is not built in this case, as the make-targets to build the cross-toolchain are not present in the $(BASE_TARGETS) variable, which is later used to create the dependency rules. Also, the comment 'Explicit ordering' has been removed, as it is mis- leading. It is make's responsibility to create the proper ordering based on the dependency rules it finds in the Makefiles Signed-off-by: Yann E.

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).

| * Create <tuple>/lib -> <sysroot>/lib symlink before installing cross gccThomas Petazzoni2010-07-272-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

For that reason, we cannot anymore just use "test -x" to test for the compiler presence. Instead, we see if $(TARGET_CC) -v and $(TARGET_CXX) -v return a zero status.

| | | | | | | | | | | | | | | | | | | | | | | Until now, the function copy_toolchain_lib_root was copying a given library to the target filesystem by assuming that it should be at the same place it was in the toolchain sysroot. However, with Buildroot hiding libstdc++ in /usr/<target-name>/lib(64), this isn't correct, and it is probably safer not to rely on the toolchain organization anyway. Therefore : * Instead of having a single EXTERNAL_LIBS variable, we now have LIB_EXTERNAL_LIBS and USR_LIB_EXTERNAL_LIBS, which respectively list the libraries that should be copied to /lib and /usr/lib. As of today, only libstdc++ is part of the second list. * The copy_toolchain_lib_root takes another argument, which is the destination directory of the library, relative to $(TARGET_DIR) Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
