Thanks. This'll help me figure out which config.h stuff I'll need
for getting
this stuff to work on other platforms.
One other problem that I've noticed recently is that LLVM is very
finicky about
which version of GCC it is compiled under. For example, GCC 3.2 and 3.2.1 work,
but 3.3 doesn't. Some of this seems to be simple header file stuff (using
assert()
without assert.h, etc) but some of it is a little more complicated. I've
been
doing a little work on this recently since a wider range of GCC compilers will
make
it easier for people to compile LLVM once it is released.
Just out of curiousity, which GCC did you use under FreeBSD?
Also, would you be interested in trying out the current autoconf stuff on
your
FreeBSD box? So far I've only tested my autoconf work on Solaris and Linux,
so I
don't know how well it handles a different architecture.
