glibc staging puts .a files in /lib

Hi

I have been seeing this problem where link would fail for libgcc when building libgcc with some weird messages like

version node not found for symbol __longjmp@@GLIBC_2.3.4

also Leon was seeing same issue on eglibc. I tracked this problem to this problem in eglibc that it was installing libc.a in $sysroot/lib where as all .a files should be in $sysroot/usr/lib then I saw that this was being done in do_stage in glibc-stage.inc

Anyway the problem was that in glibc we use install-lib and install-headers targets which does not put the /usr/lib/libc.so and /usr/lib/libpthread.so scripts. If we did use 'install' these scripts would be installed correctly.

Anyway then do_stage tries to manually generate those files and I am seeing that even in glibc these paths are not correct and .a files are copied into $sysroot/lib

The attached patch fixes it for glibc. Eglibc also needs similar fix but I decided to use make install in eglibc which makes it much easier.

OK ?

Thanks

Hello Khem,

Kudos Khem! Thank you very much for investigating this; I would not have been able to track it down so quickly.

It's good to have your toolchain expertise around, very much appreciated.

I just wonder why we didn't see this issue on glibc yet? Even with my machine (mpc8313e-rdb) this didn't show up earlier.
Could it be the (older) version of glibc I used?

Regards,

Leon

yes. The 2.6.1 glibc's libc.a does link silently. Thats why it was still working there.
