What does "knowing all options which must be configured" mean?

I am led to believe it is: zlib, gmp, mpfr, mpc, isl, > expat, binutils, gcc, glibc, and gdb. https://gcc.gnu.org/install/prerequisites.html should be clear. isl is optional, it's not required. expat is not needed. zlib is not needed, because the source for it is included in the GCC tree. > 2) How do I specify each of the above to be reliant on the versions of > other programs that it may depend on being used for the toolchain? > > Ideally these toolchains would not use system libraries if CHOST is > the same as BHOST. > > 3) Are there any architecture specific options for any of the possible > targets? Read the docs. https://gcc.gnu.org/install/specific.html
