Building shared monolithic library on MSYS/MinGW64, can't locate wxwidgets libraries

[sokolas]

I've tried building wxlua and wxwidgets as a static library (as described here), and everything works fine. Now, I need to have wxWidgets as a shared library, to expose some of its functionality to other libraries I plan to use. So, I've build wxWidgets 3.2.6 and 3.2.2.1 (not sure if the version is relevant, as the issue is related to finding the libraries) as a shared monolithic library:

./configure --prefix="$INSTALL_DIR"  --disable-debug \
    --enable-monolithic \
    --enable-compat30 \
    --enable-privatefonts \
    --with-libjpeg=builtin --with-libpng=builtin --with-libtiff=builtin --with-expat=builtin \
    --with-zlib=builtin \
    CFLAGS="-Os" CXXFLAGS="-Os -DNO_CXX11_REGEX"
  make -j1 SHARED=1 || { echo "Error: failed to build wxWidgets"; exit 1; }
  make install

The result is libwx_mswu-3.2.dll.a in INSTALL_DIR/lib and wxmsw32u_gcc_custom.dll in INSTALL_DIR/bin. Then I'm trying to build wxlua like this:

cmake -G "MSYS Makefiles" -DCMAKE_INSTALL_PREFIX="$INSTALL_DIR" -DCMAKE_BUILD_TYPE=MinSizeRel-DBUILD_SHARED_LIBS=TRUE \
    -DCMAKE_CXX_FLAGS="-DLUA_COMPAT_MODULE" \
    -DwxWidgets_CONFIG_EXECUTABLE="$INSTALL_DIR/bin/wx-config" \
    -DwxWidgets_COMPONENTS="mono" \
    -DwxLuaBind_COMPONENTS="xrc;xml;media;richtext;propgrid;gl;html;adv;core;net;base" \
    -DwxLua_LUA_LIBRARY_USE_BUILTIN=FALSE \
    -DwxLua_LUA_INCLUDE_DIR="$INSTALL_DIR/include/luajit-2.1" -DwxLua_LUA_LIBRARY="$INSTALL_DIR/lib/lua$LUAV.dll" .
  (cd modules/luamodule; make $MAKEFLAGS) || { echo "Error: failed to build wxLua"; exit 1; }
  (cd modules/luamodule; make install)

and I get the following result:

-- Found wxWidgets: -L/home/user/built_test_dynamic_2024-12-31/deps/lib;;;-Wl,--subsystem,windows;-mwindows;-lwx_mswu-3.2 (found version "3.2.6")

-- * - wxWidgets_DEBUGFLAG         =

I think the issue lies somewhere in the wx-config, because when I call it I get the following:

./wx-config --libs mono
-L/home/user/built_test_dynamic_2024-12-31/deps/lib   -Wl,--subsystem,windows -mwindows -lwx_mswu-3.2

There's no .a or .dll that the cmake script relies on to parse the configuration here.

Same goes for non-monolithic build, but the libraries output is a bit different:

Found wxWidgets: -L/home/user/build_test_dynamic_separate/deps/lib;;;-Wl,--subsystem,windows;-mwindows;-lwx_mswu_xrc-3.2;-lwx_baseu_xml-3.2;-lwx_mswu_media-3.2;-lwx_mswu_richtext-3.2;-lwx_mswu_propgrid-3.2;-lwx_mswu_gl-3.2;-lwx_mswu_html-3.2;-lwx_mswu_core-3.2;-lwx_baseu_net-3.2;-lwx_baseu-3.2 (found version "3.2.2")

As you can see, there's no .a or .dll as well.

Is there any way to fix this build?

I could somewhat resolve the issue by building everything using MSVC, but the discussion may still have some worth for those who prefer GCC.
