I confirm the problem, and I think this is the right solution, but I haven't had the time to test it. But anyway: Acked-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Thomas

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. Signed-off-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> --- RESEND I hit this again while compiling xserver_xorg-server... v3: modify GNU_TARGET_NAME instead of GNU_HOST_NAME, which makes a lot more sense of course. Thank you ThomasP! I only tested this one with xserver_xorg-server on a Sourcery x86_64 toolchain and with a simple config and an internal toolchain. v2: -buildroot- instead of -buildroot_cross-, as suggested by ThomasP. package/Makefile.in | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
