gcc ?

[labeas]

I had no intentions of opening-the-can-o-worms: gcc;
but since an attempt at compiling an interesting app under
Debian7 failed, and I've been advised that C++ compilers
are a moving-target, I though TC's compiler being newer,
may succeed.

 But after installing TC64: gcc and testing it
against old minimalist C samples it gave:
 gcc Hello.c ==
/tmp/tcloop/gcc/usr/local/bin/
../lib/gcc/x86_64-unknown-linux-gnu/5.2.0/cc1:
 error while loading shared libraries: libisl.so.13:
 cannot open shared object file: No such file or directory

-> find  /  -name "*libisl*" <- empty

Is this problem easy to fix?

==TIA.
