          I made some changes to build cava using the MinGW compiler (basically the commands mentioned in the linux section of Readme):

But I face a huge wall of errors when running make. I don't think they're syntax/semantic errors, they're just redefinition errors:

How should I fix this?

looks like some general difference between linking on linux and MinGW. this maybe related:

Yes, I checked that link - there they seem to be using the -static flag twice which is causing the problem.

For those who want a crack at this, here's what I did in an MSYS2 MINGW64 shell:

First install dependencies:

pacman -S mingw-w64-x86_64-{autotools,gcc,fftw,ncurses} libtool m4 make

Then install iniparser:

cd ~
git clone https://github.com/ndevilla/iniparser
cd iniparser
make
cp libiniparser.a /mingw64/lib/

Then build cava:

cd ~
git clone https://github.com/karlstav/cava
cd cava
git apply ~/fix.patch # the above diff-patch
./autogen.sh
./configure
make

@karlstav

had to do

 LIBRARY_PATH=/mingw64/lib C_INCLUDE_PATH=/mingw64/include/  ./configure
 LIBRARY_PATH=/mingw64/lib C_INCLUDE_PATH=/mingw64/include/ make

to find ffiw, could not find ncurses, even though it was installed. maybe some bug in my mingw setup.

also had to remove this thing:

+#define mkdir(A, B) mkdir(A)

why would you add that?

got linking errors, but different:

You are using the MSYS2 shell (which will build a Cygwin/MSys2 executable).

(Compare the path of ld executable with my screenshots).

You need to use the MINGW64 shell (which will build a Win32 native executable). My changes are w.r.t. the MINGW64 build.

hmm don't understand. where and how do i install and run the mingw 64 shell?

@rashil2000

When you installed MSYS2, it should have created multiple shortcuts for launching shells - all pertaining to different build systems - MINGW64, MINGW32, CLANG, UCRT, MSYS2 etc. The MINGW64 is the one we need.

it is the one I am running. it says MINGW64 on the prompt:

Could you run this command and try again?

pacman -Rcns autotools gcc ncurses binutils

@rashil2000

also had to remove this thing:

+#define mkdir(A, B) mkdir(A)

why would you add that?

The mkdir C function takes:

  • two aguments on Unix
  • one argument on Windows, that's why
