<p>LLVM is very demanding of the host C++ compiler, and as such tends to expose
bugs in the compiler. In particular, several versions of GCC crash when trying
to compile LLVM. We routinely use GCC 3.3.3 and GCC 3.4.0 and have had success
with them. Other versions of GCC will probably work as well. GCC versions listed
here are known to not work. If you are using one of these versions, please try
to upgrade your GCC to something more recent. If you run into a problem with a
version of GCC not listed here, please <a href="mailto:llvmdev@cs.uiuc.edu">let
us know</a>. Please use the "<tt>gcc -v</tt>" command to find out which version
of GCC you are using.
</p>
<p><b>GCC versions prior to 3.0</b>: GCC 2.96.x and before had several
problems in the STL that effectively prevent it from compiling LLVM.
</p>
<p><b>GCC 3.3.2</b>: This version of GCC suffered from a <a
href="http://gcc.gnu.org/PR13392">serious bug</a> which causes it to crash in
the "<tt>convert_from_eh_region_ranges_1</tt>" GCC function.</p>
