Hi, all

I have a trouble with building GCC 4.6.0 with Graphite enabled. Here
is my flow,

Step 1. Install PPL 0.11.2

Step 2. Install CLooG 0.16.2

Step 3. Build GCC 4.6.0 with Graphite enabled

./configure --enable-cloog-backend=isl \
--with-ppl=/tmp/chenwj/install/ \
--with-cloog=/tmp/chenwj/install/

But the compilation was failed while building libgcc, here is the
error:
---------------------------------------------------------------------------------------------------------------------------------------

Do I miss something? Thanks!

Can you send the corresponding config.log file?

Hi, Tobias

Attach is libgcc's config.log. Thanks.

The error is:

configure:3268: /tmp/chenwj/build/./gcc/xgcc -B/tmp/chenwj/build/./gcc/
-B/tmp/chenwj/install/x86_64-unknown-linux-gnu/bin/

conftest.c >&5
/tmp/chenwj/build/./gcc/cc1: error while loading shared libraries:
libcloog-isl.so.1: cannot open shared object file: No such file or directory
configure:3272: $? = 1

Most probably you did not install cloog into the default system path
such that the libcloog-isl.so.1 cannot be loaded. I propose to use:

export LD_LIBRARY_PATH=/path/to/cloog/lib:/path/to/isl/lib

Hope this helps
Tobias

Thanks, Tobias. That really helps.

And this might off the topic. Are you running the LLVM Polly project?
I am interested in this project. :-)

Good. Let me know if you need further help with Graphite.

I am also contributing to Polly. But as you already stated this is off
topic on this mailing list. Please use the Polly website [1] or the
mailing list referenced on the website to get in touch. We will be happy
to help you with any questions or guide you if you plan to contribute.

Cheers
Tobi
