Re: Problem configuring gcc-4.82. with ISL

 Thanks a lot Ian.

Setting LD_LIBRARY_PATH worked. I was thrown off because it was able to find gmp, mpc, and mpfr, and I had followed the same steps for isl as well. This step is mentioned on the wiki, but it maybe useful to add this with the instructions that are in gcc-4.8.2/INSTALL/index.html.

I also needed to get install libc6-dev-i386. This was very easy, but wasn't mentioned anywhere in the requrements (I think: or maybe I misssed it).

It seems to be working. Thanks again.

 Yes, that was fixed.

 I think this is your problem.  Linking with -lisl is
 causing you to
 link against libisl.so.10, but that shared library is not
 found at
 runtime.  You need to set your LD_LIBRARY_PATH
 environment variable or
 add the directory to /etc/ld.so.conf.
