* Create <tuple>/lib -> <sysroot>/lib symlink before installing cross gccThomas Petazzoni2010-07-271-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
