llvm dev - Oct 2011 - [LLVMdev] Compile llvm-gcc fortran backend using mingw

Hello everyone!

I got following error while trying to compile llvm-gcc-4.2 using mingw:

..\llvm-gcc-4.2\obj\libcpp/../../libcpp/macro.c:1165:
undefined reference to `flag_iasm_blocks'
stub-c.o:stub-c.c:(.debug_info+0x81a0): undefined reference to
`flag_iasm_blocks'
stub-c.o:stub-c.c:(.debug_info+0x81b9): undefined reference to `iasm_state'
stub-c.o:stub-c.c:(.debug_info+0x81d8): undefined reference to
`iasm_in_operands'

Configuration command:
../configure --enable-languages=,c++,fortran --prefix=u:/libs/llvm-gcc-2.9
--program-prefix=llvm- --enable-llvm=u:/libs/llvm-2.9 --disable-bootstrap
--disable-multilib

LLVM itself was compiled & installed successfully with such configuration:
../configure --prefix=u:/libs/llvm-2.9 --enable-optimized
--enable-assertions

I tried latest sources from SVN and from official download page - result is
the same.
I followed few guides on compilation(including official one) - same.

MinGW has gcc 4.6.1 and it seems all required packages (binutils, perl,
gfortran, mpfr, gmp, etc) are installed.

I would appreciate any help on how to solve this problem.

Thank you in advance.
Pavel.

P.S.
BTW, it is little bit strange that llvm-gcc doesn't support CMake building
system.
LLVM does and it is extremely convenient....

Hi Pavel,

llvm-gcc is dead, deprecated in favour of clang and dragonegg.  It won't be
part
of the upcoming 3.0 release.  This is why no-one is interested in working on it.

Ciao, Duncan.

Thank you for quick reply.

I see, llvm-gcc is frozen....

Is there Fortran front-end for LLVM then?

The tentative release notes still say otherwise: "LLVM 3.0 will be the 
last release of llvm-gcc." (http://llvm.org/docs/ReleaseNotes.html)

I understand that llvm-gcc is being phased out in favour of dragonegg, 
but (at least according to its own website) dragonegg is still a bit 
rough around the edges and requires a patched gcc 4.5 to work. So 
llvm-gcc still serves an important role, if only for the Fortran and Ada 
compilers.
