Cross-compiling under mingw

Just running make libopusfile-0.dll in this directory should download and build opusfile and its dependencies. Some mingw libraries need to be compiled into the final package.

Generic instructions

To build opusfile under mingw, you need to first build:

• libogg
• libopus
• openssl

For 'make check' to work, you may need wine installed.

To build openssl, try:

CROSS_COMPILE="i686-w64-mingw32-" ./Configure mingw no-asm no-shared --prefix=$PWD/mingw && make depend && make -j8 && make install

To build opusfile, try:

CC=i686-w64-mingw32-gcc PKG_CONFIG_PATH=$PWD/lib/pkgconfig RANLIB=i686-w64-mingw32-ranlib make -f ../unix/Makefile

Building the release package

Running make package should produce a binary package.

The steps are something like

• Compile dynamic opusfile with:
  • ./configure --host=i686-w64-mingw32 --prefix=/path/to/builddir/mingw
    PKG_CONFIG_PATH=/path/to/builddir/mingw/lib/pkgconfig
  • make && make check && make -C doc/latex
    • If Doxygen fails because of unescaped '#' characters in URLs Update to at least Doxygen 1.8.15. Doxygen 1.8.3 also works.
• mkdir opusfile-${version}-win32
• Copy AUTHORS COPYING README.md include/opusfile.h to the release dir.
  • Don't put opusfile.h in an opusfile-${version}-win32/include directory, just put it straight in the release dir.
• Merge changes between README.md and the version in the last binary release. E.g. it's good to include versions of the dependencies, release notes, etc.
• Convert README.md to DOS line endings.
• Copy .libs/libopusfile-0.dll to the release dir.
• Copy .libs/libopusfile.a to the release dir.
• Copy .libs/libopusurl-0.dll to the release dir.
• Copy .libs/libopusurl.a to the release dir.
• Copy mingw/bin/*.dll to the release dir for dependencies.
• Copy any other dependent dlls, e.g. on Fedora 32 I needed to copy /usr/i686-w64-mingw32/sys-root/mingw/bin/libgcc_s_dw2-1.dll /usr/i686-w64-mingw32/sys-root/mingw/bin/libwinpthread-1.dll On Fedora 23 I needed to copy /usr/i686-w64-mingw32/sys-root/mingw/bin/libgcc_s_sjlj-1.dll /usr/i686-w64-mingw32/sys-root/mingw/bin/libwinpthread-1.dll On Gentoo I needed to copy /usr/lib64/gcc/i686-w64-mingw32/7.3.0/libgcc_s_sjlj-1.dll TODO: It may be possible to avoid this with CFLAGS="-static-libgcc"
• Copy doc/latex/refman.pdf to opusfile-${version}-win32/opusfile-${version}.pdf
• Copy examples/.libs/*.exe to the release dir.
• Run "i686-w64-ming32-strip *.dll *.a *.exe" in the release dir.
• In the release dir, run: sha256sum * > SHA256SUMS.txt gpg --detach-sign --armor SHA256SUMS.txt
• In the parent directory, create the archive: zip -r opusfile-${version}-win32.zip opusfile-${version}-win32/*
• Copy the archive to a clean system and verify the examples work to make sure you've included all the necessary libraries.
