hello, i am new to llvm and can't manage to compile the gcc backend. my steps: i compile the llvm-source first as suggested in "README.LLVM" that works fine and without any issues. then i make a new dir called build. from there i do the following: stefan at ubuntu:~/programs/llvm/build$ ../llvm-gcc4-1.9.source/configure --enable-languages=c,c++ --prefix=/usr/local/ --disable-shared then after some time i get the follwing error: make[2]: Entering directory '/home/stefan/programs/llvm/build/gcc' /home/stefan/programs/llvm/build/gcc/xgcc -B/home/stefan/programs/llvm/build/gcc/ -B/usr/local//i686-pc-linux-gnu/bin/ -B/usr/local//i686-pc-linux-gnu/lib/ -isystem /usr/local//i686-pc-linux-gnu/include -isystem /usr/local//i686-pc-linux-gnu/sys-include -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. -I../../llvm-gcc4-1.9.source/gcc -I../../llvm-gcc4-1.9.source/gcc/. -I../../llvm-gcc4-1.9.source/gcc/../include -I../../llvm-gcc4-1.9.source/gcc/../libcpp/include -DL_mulvdi3 -c ../../llvm-gcc4-1.9.source/gcc/libgcc2.c -o libgcc/./_mulvdi3.o ../../llvm-gcc4-1.9.source/gcc/libgcc2.c:403: internal compiler error: in prune_unused_types_update_strings, at dwarf2out.c:14372 Please submit a full bug report, with preprocessed source if appropriate.

This looks like the 1.9 version of llvm-gcc. Is your LLVM also the 1.9 version? If not, it definitely won't work (llvm-gcc4 and llvm must stay closely in sync). 2. This configure line is not correct for llvm-gcc4. At the very least you need --enable-llvm=/path/to/llvm/build/root. You might also consider --disable-nls if you don't care about national language support (makes build faster). Finally, if you built llvm debug (the default if you checked it out from CVS), then you should also have --enable-checking (to build llvm-gcc debug as well).> then after some time i get the follwing error:I think you also did "make"> > make[2]: Entering directory '/home/stefan/programs/llvm/build/gcc' > /home/stefan/programs/llvm/build/gcc/xgcc -B/home/stefan/programs/llvm/build/gcc/ -B/usr/local//i686-pc-linux-gnu/bin/ -B/usr/local//i686-pc-linux-gnu/lib/ -isystem /usr/local//i686-pc-linux-gnu/include -isystem /usr/local//i686-pc-linux-gnu/sys-include -O2 -DIN_GCC -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g -DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I. -I../../llvm-gcc4-1.9.source/gcc -I../../llvm-gcc4-1.9.source/gcc/. -I../../llvm-gcc4-1.9.source/gcc/../include -I../../llvm-gcc4-1.9.source/gcc/../libcpp/include -DL_mulvdi3 -c ../../llvm-gcc4-1.9.source/gcc/libgcc2.c -o > libgcc/./_mulvdi3.o > ../../llvm-gcc4-1.9.source/gcc/libgcc2.c:403: internal compiler error: in > prune_unused_types_update_strings, at dwarf2out.c:14372 > Please submit a full bug report, > with preprocessed source if appropriate. > See <URL:http://llvm.org/bugs> for instructions.I'm not sure what this is about.

ok thanks a lot. i think the "--enable-llvm=..." command did it for
me. in
fact i have to admit that i got confused because when i started i followed
the instaructions in README.LLVM step by step. that braught me an error
somewhere with the problem that "libstdc++.so.6" was searching for
GCC4.2.0
which doesn't exist on my system ("libstdc++.so.6" is of version
4.1.0?!)
then i found the script with which the 1.8 - versions included in the package
list of ubuntu were built - here i also found the "--disable-shared"
switch.
so i took the configure syntax of the script and ran into the other error. it
was a bit silly of me not to try to merge both ;)
my suggestion:
add in README.LLVM for the linux-section that in the case one sees the error
with GCC4.2.0 the switch "--disable-shared" should be added to the
configure
command.
nevertheless thanks a lot for your help!!

At least on HEAD. Probably, it was missed in 1.9 release, sorry. It's PR1017. -- With best regards, Anton Korobeynikov. Faculty of Mathematics & Mechanics, Saint Petersburg State University.
