llvm dev - May 2009 - [LLVMdev] Using non-system compiler to build llvm and llvm-gcc front end

I am still having problems getting everything installed. I realized that the
successful build of llvm-2.5 had in fact been configured to use the system
gcc (4.1.2). However, I was unable to sucessfully build llvm-gcc with gcc
4.1.2.

I went back and attempted to build llvm-2.5 with gcc-4.2.4 (installed in a
separate directory from system gcc). However, I got the same build error as
before.

Then I went back again to attempt to build llvm-2.5 with the system gcc, and
was unable to reproduce a successful build. So something is wrong with my
recollection of history.

I think I am just configuring incorrectly. I would like to use the
installation of gcc-4.2.4, which is located in /pkg/bin/gcc-4.2.4. Perhaps
someone has done something similar and can provide me a working example?

Details:

Scott,
did you try a simple

 $ ../llvm-2.5/configure --prefix=/pkg/bin/llvm/ CC=/pkg/bin/gcc-4.2.4/bin/gcc
CXX=/pkg/bin/gcc-4.2.4/bin/g++

This is how I use to configure for non-system gcc 4.3.2 and it works well. The
right headers are included automatically
from the correct directory, and besides that I think that none of the std
libraries is linked statically I guess it would
pick the right ones as well. Just make sure to load the right shared libs on
runtime.


Regards, Christian

So it is looking in /usr/lib64/ for libstdc++.so.6, when in fact I want it to
look in /pkg//bin/gcc-4.2.4/lib64/ (which I thought I had specified with the
configuration).

Any help would be appreciated.

Thanks,

how about:

export PATH=/pkg/bin/:$PATH
../llvm-2.5/configure --prefix=/pkg/bin/llvm/

instead?

Ciao,

Duncan.

Thanks for the suggestions. It looks like Duncan's suggestion got me a
step closer, but I still can't build llvm-gcc...

Tried that, same error.

I did that, and then "make tools-only" -- which resulted in a
successful build of llvm-2.5. Then I went to build llvm-gcc:

../llvm-gcc4.2-2.5.source/configure
--prefix=/pkg/build/llvm/llvm-gcc/install --program-prefix=llvm-
--enable-llvm=/pkg/build/llvm/llvm-obj/ --enable-languages=c,c++

make LLVM_VERSION_INFO=2.5

and I get this error (which, according to
http://www.mail-archive.com/llvmbugs at cs.uiuc.edu/msg02575.html might
mean I am using a bad version of gcc)...

/pkg/build/llvm/llvm-gcc/obj/./gcc/xgcc

../../llvm-gcc4.2-2.5.source/gcc/libgcov.c:644: internal compiler error: Aborted

So I tried this config for llvm-gcc:

$ ../llvm-gcc4.2-2.5.source/configure
--prefix=/pkg/build/llvm/llvm-gcc/install --program-prefix=llvm-
--enable-llvm=/pkg/build/llvm/llvm-obj/ --enable-languages=c,c++
CC=/pkg/bin/gcc-4.2.4/bin/gcc CXX=/pkg/bin/gcc-4.2.4/bin/g++

but got:

configure: warning: CC=/pkg/bin/gcc-4.2.4/bin/gcc: invalid host type
configure: warning: CXX=/pkg/bin/gcc-4.2.4/bin/g++: invalid host type
configure: error: can only configure for one host and one target at a time

How do I tell llvm-gcc config to use the right version of gcc?
/pkg/bin/ is in my path thanks to the suggestion from Duncan.
