Configuring GCC 4.8.1, Unable to find a usable ISL

[Ivan Stalev]

Hi,

Okay, now I configured like this:

../gcc-4.8.1/configure --prefix=/home/mdl/ids103/gcc-4.8.1-install
--enable-shared --enable-threads=posix --enable-__cxa_atexit
--enable-clocale=gnu --enable-lto --enable-languages=c,c++,fortran
--with-ld=/home/mdl/ids103/binutils-2.24-install/bin
--with-as=/home/mdl/ids103/binutils-2.24-install/bin
--disable-multilib --with-cloog=/home/mdl/ids103/install
--with-gmp=/home/mdl/ids103/install
--with-mpfr=/home/mdl/ids103/install
--with-mpc=/home/mdl/ids103/install

I started the build, and 10 minutes into it, I get this error:

checking for x86_64-unknown-linux-gnu-gcc...
/home/mdl/ids103/gcc-4.8.1-build/./gcc/xgcc
-B/home/mdl/ids103/gcc-4.8.1-build/./gcc/

-isystem /home/mdl/ids103/gcc-4.8.1-install/x86_64-unknown-linux-gnu/sys-include
checking for suffix of object files... configure: error: in
`/home/mdl/ids103/gcc-4.8.1-build/x86_64-unknown-linux-gnu/libgcc':
configure: error: cannot compute suffix of object files: cannot compile

The only errors in config.log seem to be related to ISL, and also these:

gcc: error: unrecognized command line option '-V'
gcc: error: unrecognized command line option '-qversion'
g++: error: unrecognized command line option '-V'
g++: error: unrecognized command line option '-qversion'

Thanks again.
