Hi,
I'm trying to build a i686-pc-linux-gnu to x86_64-pc-linux-gnu cross compiler.
I had some problems getting it to relocate but I found that if I set prefix = sysroot
the define TARGET_SYSTEM_ROOT_RELOCATABLE is set, hope this solves that.
Now the problem is that when building libgcc xgcc get wrong sysroot
It is looking for /lib64/libc.so.6 in system root and not by sysroot.
I built glibc with prefix=/usr and installed it in the same directory as gccs sysroot.
When I try to link it manually(copy the line and add -v) to see the what xgcc is passing to the linker I see two thing.
xgcc don't have the same sysroot as I wrote in prefix and if I copy lib64 to the sysroot that is is passed to the linker it still don't work.
(does this have anything to do with -with-build-sysroot?)
Don't know that kind of information that is useful, maybe I'm doing it all wrong?
Gcc is configured with
--target= x86_64-pc-linux-gnu --prefix=/tools/gcc/delivery/gcc_linux_sfk-linux64_4.6.3 \
--with-sysroot=/tools/gcc/delivery/gcc_linux_sfk-linux64_4.6.3 \
--with-gnu-as --with-gnu-ld --with-gcc \
--enable-languages=c,c++ \
--disable-nls --disable-multilib ;\
Regards,
Johan
