Hello everybody,
What can we assume on our C compiler? Is it always gcc?
First of all, compiler choices can always be overridden using SAGE_PORT
or SAGE_INSTALL_GCC. But let's assume that those variables are undefined.
In that case, you can assume that the compiler is GCC-compatible, so it
could be GCC or it could be Clang or possibly a different compiler (ICC
maybe?). The version is at least version 4.4 (but not 4.6)
That being said, if there is some future which really requires a more
recent compiler (say, for C++11 support), I wouldn't mind updating the
prerequisites.
Note that this talks only about the compiler, which is just one piece of
the toolchain. Many compatibility problems are in fact due to the
linker, where less assumptions can be made.
