Here is a sample for Crosstool-NG (arc-2022.09 branch) which allows to build native toolchain for ARC HS 4x with native GDB:

[CFG  ]    Try the --with-gmp and/or --with-mpfr options to specify
[CFG  ]    their locations.  If you obtained GMP and/or MPFR from a vendor
[CFG  ]    distribution package, make sure that you have installed both the libraries
[CFG  ]    and the header files.  They may be located in separate packages.

Seems like it cannot find MPFR because it's mandatory for GDB 13 and Crosstool-NG cannot handle it. The question is why GMP is built and found by build system but MPFR is not?

kolerov commented 1 year ago

Options --with-gmp= and --with-mpfr= are not passed to configure in build scripts for native GDB. I am preparing patches for this issue and going to push them to upstream.

kolerov commented 1 year ago

All necessary changes are merged with upstream Crosstool-NG: https://github.com/crosstool-ng/crosstool-ng/pull/1954. Since then native GDB may be built successfully.
