Re: gcc(0614 cvs) compile error on solaris 8

In article <Pine.GSO.4.05.10106142316290.8553-100000@account.kouf.org>
you write:

> i configured with following options...
> ../configure --prefix=/export/home/imyaman/local --enable-shared
> --enable-threads=pthread --enable-languages=java,objc --enable-libgcj
> --enable-nls 

Luckily, your problem is not a result of recent patches submitted to
improve threading in libstdc++-v3, but it does mean that I almost
fully understand all configuration related to threading for many
platforms. ;-)

Please use:

--enable-threads=posix

instead of:

--enable-threads=pthread

In light of your report, I am currently attempting to figure out how
to extend the documentation to best help people in this area for the
pending gcc 3.0 release.  I do not yet know why gcc/config.gcc in
conjunction with gcc/configure isn't catching an unknown thread
configuration...

In gcc/config.gcc, *many* platforms explicitly map
--enable-threads=pthread to posix but some do not.  Solaris is one
such port that does not do such mapping...

In gcc/configure, if config.gcc didn't set thread_file to anything
then by default thread_file is set to whatever you listed after
`--enable-threads='.  Since the solaris configuration doesn't map
pthread to posix, you get a reference to gthr-pthread.h which doesn't
exist in the $srcdir/gcc.

Loren
