Some dependencies result in a segfault under gcc3, source/blender/.libs/libblender_blender.la has many -lm, -lc if some are removed it will compile.

My fatal error,

Code:

any clues?

I also have this problem on the following system: -march=pentium4 -mmmx -mfpmath=sse -msse -msse2 -O3

hmm,

Did you build from cvs or from the 2.26 source package?
A lot of updates have been made to the buildsystem the last couple of days, so could you try to build from a recent cvs?

With regards,
Michel

I originally tried from the 2.26 source, and then I also tried from the 2003-03-26 CVS snapshot tarball as I heard that there were autoconf fixes, same error. With the snapshot, I had to do the following before ./configure would even work:

aclocal &&
autoconf &&
touch config.sub &&
automake

There's no "&&" after automake as it had errors, but managed to create 'Makefile.in', which was needed by ./configure. Then it still complained that "config.guess" couldn't be found and that 'source/blender/bpython/Makefile.am' couldn't find './compile'. But it still continued, so...

However, I think my error is slightly different, after looking at it, as I don't have as many "-lm"'s in my compile log, though I do have quite a few. Will post the exact error I'm getting later today.

Any idea on when 2.27 will be released?

don't do all that run the bootstrap script which will fix everything and
build a configure script.

If your still getting errors you may need to update your versions of
autoconf, automake.

Ah yes, I forgot about the bootstrap. I'll try that when I get home.

As for the latest versions...well, I run a source-based distro, so we always have the latest.

Here's the error (this is using ./bootstrap to set things up, which is much nicer than the manual way I was trying ):

I also get this error right after the above error:

Hmm....for some reason the [code] tags didn't work. They worked during my first Preview, but then stopped working. Ah well, I'll just stick to normal text then.

hm, looking at this, makes me suspect that you did a checkout from cvs . In the last few days, some things have changed in the auto* tools. And one of them is that the linking has changed. This is precisely an error that somehow occurs when doing a 'make', 'cvs update', 'make'. Normally this should work, but I'm not confident it works when changes to the build system are made. So I have to ask you:
Did you do a 'make clean' before you did a make?

With regards,
Michel

I was using the 2.26 tarball. I can try with a 'make clean' before ./bootstrap. I had also tried one of the CVS snapshots, same error. All of my compiles started from a clean untar/checkout.
