libopenmpt mingw-w64 binary info

Current built version as of 2019/09/27 is 0.4.7+r12088.pkg

  • mingw binaries (.dll): bin/[x86 or x86_64]/mingw
  • mingw import libraries (.dll.a): lib/[x86 or x86_64]/mingw

Building libopenmpt with mingw-w64

libopenmpt must be built from the Makefile / Android dev package in the Downloads page

Use the mingw-w64 distributions from SourceForge.

You can download the appropriate 7-zip archive, extract to a folder of your choice, remove any existing mingw directories from your PATH, then call mingw32-make.exe from its direct location.

FOR LIBOPENMPT, YOU MUST USE A MINGW PACKAGE THAT SUPPORTS THE POSIX THREADING MODEL! DO NOT COMPILE WITH A WIN32 THREADING MODEL!

I use GCC 7.3.0:

x86 build instructions

set CFLAGS=-march=pentium -static-libgcc
set CXXFLAGS=-march=pentium -static-libgcc -static-libstdc++
set LDFLAGS=-Wl,--out-implib,bin/libopenmpt.dll.a -Wl,-Bstatic,--whole-archive -lwinpthread -Wl,-Bdynamic,--no-whole-archive

cd [libopenmpt-make-src]
[x86-mingw-w64-bin]/mingw32-make.exe CONFIG=mingw64-win32

libopenmpt.dll and libopenmpt.dll.a will be built in the bin/ folder.

x86_64 build instructions

set CFLAGS=-march=nocona -static-libgcc
set CXXFLAGS=-march=nocona -static-libgcc -static-libstdc++
set LDFLAGS=-Wl,--out-implib,bin/libopenmpt.dll.a -Wl,-Bstatic,--whole-archive -lwinpthread -Wl,-Bdynamic,--no-whole-archive

cd [libopenmpt-make-src]
[x86_64-mingw-w64-bin]/mingw32-make.exe CONFIG=mingw64-win64

libopenmpt.dll and libopenmpt.dll.a will be built in the bin/ folder.
