You might just say: 'Yeah! crosstool-NG's got its own repo!". Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup. That means I'm putting backups in place in the afternoon. That also means we've lost history... :-(

Patch to fix following test case failure:
|
|
|
|
=== libstdc++-v3 tests ===
|
|
FAIL: thread/pthread1.cc (test for excess errors)
|
|
Excess errors:
|
|
/opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/sh4-unknown-linux-gnu/bin/ld: cannot find -lthread
|
|
collect2: ld returned 1 exit status
|
|
|
|
Note that *any* program compiled with -pthread fails:
|
|
|
|
/opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/bin/sh4-unknown-linux-gnu-gcc hello.c -pthread
|
|
/opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/lib/gcc-lib/sh4-unknown-linux-gnu/3.3.1/../../../../sh4-unknown-linux-gnu/bin/ld: cannot find -lthread
|
|
collect2: ld returned 1 exit status
|
|
|
|
Compiling with -lpthread on the other hand works fine:
|
|
/opt/cegl-2.0/sh4-unknown-linux-gnu/gcc-ss-3_3-20030714-glibc-2.2.5/bin/sh4-unknown-linux-gnu-gcc hello.c -lpthread
|
|
|
|
So -pthread is broken in some trivial way; it should invoke -lpthread, not -lthread,
|
|
at least when targeting Linux.
|
|
|
|
http://www.sh-linux.org/rpm-2003/SRPMS/gcc-3.2.3-3.src.rpm contains a jumbo patch,
|
|
gcc-20030210-sh-linux-1.patch, that includes a fix for this. Here's the
|
|
appropriate hunk (brings in a fix for the documented -mieee option).
|
|
No idea if this fix is completely right, but it works for me...
