Support --with-{gmp,mpfr,mpc}

[bschommer]

It would be nice if it was possible to pass these options to the configure scripts since allow it to use a local installation of newer versions of gmp,mpc and mpfr without root rights.

[palmer-dabbelt]

Is this just for GCC? If so, you're not supposed to do that, but are instead supposed to call contrib/download_prerequisites. We have an autoconf widget that's supposed to be doing that in riscv-gnu-toolchain, is it not detecting your system doesn't have the required libraries?

No it does not work it currently fails with:

configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+. Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify their locations. Source code for these libraries can be found at their respective hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/. See also http://gcc.gnu.org/install/prerequisites.html for additional info. If you obtained GMP, MPFR and/or MPC from a vendor distribution package, make sure that you have installed both the libraries and the header

[palmer-dabbelt]

Can you post your config.log from riscv-gnu-toolchain/build? I'll look at it when I get to a computer.

For now you can just run download_prerequisites manually.

With calling the download_prequisites manually it worked.

[palmer-dabbelt]

Can I have riscv-gnu-toolchain/build/config.log and riscv-gnu-toolchain/build/build-gcc-newlib-stage1/config.log? That way I'll be able to see what autoconf did on your system, as this all builds for us.

Both configs are for the build run with calling download_prequisites manually.

OK, sorry, I think I just screwed it up. Thanks for the bug report!

I've opened a riscv-gnu-toolchain pull request: https://github.com/riscv/riscv-gnu-toolchain/pull/240 . Since this is a riscv-gnu-toolchain issue I'm going to close this bug, if that doesn't work then please post over there.

Thanks!

I am looking forward to see anything acceptable for https://go.googlesource.com/gollvm/ project - it has all the above libraries among it's dependencies. I am working on Fedora 33, under qemu.
