* gcc: remove option on SJLJ exceptionsThomas Petazzoni2010-07-283-14/+0
| | | | | | | | | | | 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>

* 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.

| * toolchain: remove redundant and incorrect --with-build-time-tools optionThomas Petazzoni2010-07-271-2/+0
| | | | | | | | | | | | | | | | | | | | | | This option is already part of the gcc configure options through the BR2_CONFIGURE_BUILD_TOOLS variable (in toolchain/Makefile.in). Additionnally, the value that was passed in the AVR32 specific case was incorrect: it was $(STAGING_DIR)/$(REAL_GNU_TARGET_NAME)/bin instead of $(STAGING_DIR)/usr/$(REAL_GNU_TARGET_NAME)/bin.

| | | | | | | | | | | | | | | | | | The variable BR2_SYSROOT_STAGING_DESTDIR is no longer used, since now the prefix for gcc is already set to the correct location. The variable BR2_SYSROOT_TARGET_DESTDIR was already unused. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

| | | | | | | | | | | | | | | | | | | | | | | | 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).

| * 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | Following the changes to TARGET_CC/TARGET_CXX to include the --sysroot option, these variables not only contain the path to the compiler, but also the --sysroot option. 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. Moreover, --sysroot now needs to be filtered out of $(TARGET_CC) and not $(TARGET_CFLAGS) when asking the toolchain for its original sysroot and arch sysroot.

Moreover, the --isysroot option is implied by --sysroot so there's no need to specify both. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com>

* external-toolchain: hardcode the destination directory for a libraryThomas Petazzoni2010-07-061-13/+17
| | | | | | | | | | | | | | | | | | | | | | | 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>

* ext-toolchain: Fix ARCH_SYSROOT detectionThomas Petazzoni2010-07-061-9/+9
| | | | | | | | | | | | | | | | | | | | | | For the detection of the ARCH_SYSROOT_DIR (which contains the C library variant specific to the compiler flags), we used to pass only the -march argument instead of the full TARGET_CFLAGS. This was done because TARGET_CFLAGS contains --sysroot, and we don't want to tell here the compiler which sysroot to use, because we're specifically asking the compiler where the *normal* arch sysroot directory is. Unfortunately, there are some multilib variants that aren't decided only based on -march, but also on -msoft-float or other compiler flags. Therefore, we take the opposite approach: pass the full TARGET_CFLAGS, from which we have stripped the --sysroot option. For example, this allows a PowerPC CodeSourcery toolchain, on which we're using the soft-float multilib variant, to work properly as an external toolchain.
