Description Petric Frank 2009-11-04 16:08:01 UTC

Creating a cross development environment for MIPS/nommu using sys-devel/crossdev.

During configuration of uclibc for the target mips w/o mmu only static libs can be generated. It seems not being possible to create shared libs. The compile option -fdpic is not supported for (at least) mips/nommu target.
So only static libs can be created.
See bug item #291787

As a result gcc should also not try to create them.

But build process tries to create libgcc_s.so and fails. See attached log.

As test I hacked toolchain.eclass to jam in the configure option "--disable-shared". Now the gcc stage2 build went ok.


Reproducible: Always

Steps to Reproduce:
1.build static-only uclibc
2.crossdev - build stage2 gcc
3.failure

Actual Results:  
crossdev fails to build stage2 gcc when uclibc was built static-only

Expected Results:  
gcc statge2 completes successful

Created attachment 209237 [details]
gcc stage2 log file

The log (stripped down becuse it was > 1.5 MB in size) of the crossdev gcc stage2 generation.

fixed for uClibc targets

I think this is a bad fix since many MIPS systems have less > 16Mb.
On those systems shared memory (even for some bytes) is important.

your report has nothing to do with this bug.  stick to the bug you already filed.
