Building AGG in msys2 causes error Invalid configuration `x86_64-pc-msys': system `msys' not recognized

Question

I want to install pypotrace. To this end I'm following this tutorial. However when I get to the line ./autogen.sh; make

I get the error:

(specifically the line):

I extracted both packages in my C:\src folder. Both are easy to build by executing ./configure; make and ./autogen.sh; make respectively, on MSYS prompt.

I looked at this discussion, however gcc -dumpmachinegives me the error

-bash: /usr/bin/gcc: No such file or directory

I also tried installing pypotrace using pip via pip install pypotrace, however this gave the error

As it may matter, here is my PATH environment variable I have seen mentioned a few times:

Anybody who knows how to get pypotrace to run on windows 10(so either one of the above methods or maybe something else entirely)? Or do you guys think that configuration issues are better posted in a place like superuser?

Answer 1

As explained in this answer, it should work on MSYS (not mingw) if you update config.sub, and config.guess, just do

wget 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.guess;hb=HEAD' -O './config.guess'
wget 'http://git.savannah.gnu.org/gitweb/?p=config.git;a=blob_plain;f=config.sub;hb=HEAD' -O './config.sub'

./configure

However maybe you just want to do a mingw build.
