mingw32 bootstrap fails to find MPC when using custom prefix

[contextnerror]

I wanted to try keeping the wine ports in their own prefix to manage them separately from my other ports. This didn't work. i686-w64-mingw32-gcc-bootstrap fails at the configure step, specifically when looking for MPC.

configure:8305: error: Building GCC requires GMP 4.2+, MPFR 3.1.0+ 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
https://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
files.  They may be located in separate packages.

For reference, the prefix was configured with these arguments: --prefix=/opt/merlot --with-applications-dir=/opt/merlot/Applications --without-startupitems --with-curlprefix=/opt/bootstrap

Logfiles are included. They are: bad-config: config log from custom prefix good-config: config log from running sudo /opt/local/bin/port configure i686-w64-mingw32-gcc-bootstrap, which works fine main: wine-devel log Terminal Saved Output: All output, from initial clone to failure

Could you provide the main.log for i686-w64-mingw32-gcc-bootstrap

[contextnerror]

Sorry, not sure how I missed that. Here. main.log

[Gcenx]

That’s very strange as the relevant configure options are being passed to help configure find the requested headers…

[Gcenx]

Started to dig into this more and see it does find the header but can’t find a function, checked Macports-ports and they’ve already resolved the issue on there end https://github.com/macports/macports-ports/commit/9332dbb202005f90c4aa5c9e069edeb4d804d117

You’ll need to do selfupdate and upgrade all installed ports and then it should work.

Yup, that fixed it.
