[Llvm-bgq-discuss] bgclang r220548-20141024 on vesta/mira

[Christophe Prud'homme]

Hello


thank you very much for this release !
We use advanced c++11, the latest boost (and boost.filesystem...) and
various other libs.

I have the following problem at link time with this release. We have the
V1R2M2 driver
but not /V1R2M2_base_4.7.2/gnu-linux-4.7.2

/bglocal/fe/pub/Clang/r220548-20141024/r220548-20141024/binutils/bin/ld:
cannot find
/bgsys/drivers/toolchain/V1R2M2_base_4.7.2/gnu-linux-4.7.2/powerpc64-bgq-linux//lib/libc.so.6

/bglocal/fe/pub/Clang/r220548-20141024/r220548-20141024/binutils/bin/ld:
cannot find
/bgsys/drivers/toolchain/V1R2M2_base_4.7.2/gnu-linux-4.7.2/powerpc64-bgq-linux//lib/libc_nonshared.a

/bglocal/fe/pub/Clang/r220548-20141024/r220548-20141024/binutils/bin/ld:
cannot find
/bgsys/drivers/toolchain/V1R2M2_base_4.7.2/gnu-linux-4.7.2/powerpc64-bgq-linux//lib/ld64.so.1

rather we have

/bgsys/drivers/toolchain/V1R2M2_base/gnu-linux

I guess the proper symlink will do. Do you see any other solution ?

did we miss something ?


Best regards

C.
