maybe use wx-config when gcc is found in wxCompile.nim

[retsyo]

on my sys2+mingw, the make file runs exactly

$ make -f makefile.unx
g++ -c `wx-config --cxxflags` -o bombs.o bombs.cpp
g++ -c `wx-config --cxxflags` -o game.o game.cpp
g++ -c `wx-config --cxxflags` -o bombs1.o bombs1.cpp
g++ -o bombs bombs.o game.o bombs1.o `wx-config --libs`

to build binary files. The wx-config can handle all kinds of compile/link situation while considering real wxwidget's installation (for example, shared/static lib, monolithic build, libtiff...)

[Peter Munch-Ellingsen]

The wxCompile file already uses wx-config if you don't pass it a path explicitly. At least on Linux. If you have a way to run it on Windows as well than I'd be happy to merge a PR which implements that. I have never run the Windows part of the script. That was developed by someone else.

Any status on this?

long time passed

firstly

$ nim c --define:"wxWidgetsPath:/e/msys64/home/USER/wxWidgets" controlgallery.nim
R:\wxnim-0.8.0\examples\genuimacro\command line(1, 2) Error: invalid command line option: '--wxWidgetsPath;E:\msys64\home\USER\wxWidgets'

then

$ nim c --define:"wxWidgetsPath:e:\msys64\home\USER\wxWidgets" controlgallery.nim
...

gcc.exe: error: `wx-config: No such file or directory

so the passC and passL in wxCompile.nim is read wrongly because the ``` symbol is treat bad

first font.nim should be edited as #13

finally I get it work on my Windows, but this is not a good way.

Here is the instruction to build in MSYS2 + MingW64 on windows 64 bits

1. first, get the latest wxWidgets source, decompress it into, for example, E:\msys64\home\USER\wxWidgets\

2. in E:\msys64\home\USER\wxWidgets\

mkdir msw_build
cd msw_build
../configure --disable-shared --disable-debug --enable-threads --enable-monolithic --enable-unicode  --enable-compat28 --enable-graphics_ctx --prefix=/opt/windows_64
make -j8

3. now run and copy the output

$ /opt/windows_64/bin/wx-config --libs all
-L/opt/windows_64/lib   -Wl,--subsystem,windows -mwindows /opt/windows_64/lib/libwx_mswu-3.1.a -lpng -lz -ljpeg -ltiff -llzma -lwxregexu-3.1 -lwxscintilla-3.1 -lz -lexpat -lpng -lz -ljpeg -ltiff -llzma -lz -lrpcrt4 -loleaut32 -lole32 -luuid -llzma -luxtheme -lwinspool -lwinmm -lshell32 -lshlwapi -lcomctl32 -lcomdlg32 -ladvapi32 -lversion -lwsock32 -lgdi32 -loleacc

$ /opt/windows_64/bin/wx-config --cflags
-I/opt/windows_64/lib/wx/include/msw-unicode-static-3.1 -I/opt/windows_64/include/wx-3.1 -D_FILE_OFFSET_BITS=64 -DwxDEBUG_LEVEL=0 -D__WXMSW__

4. modify wxCompile.nim according to what you get in step 3. But you must expand /opt to the expression of harddisk driver, and use / to replace \ in the directory

{.passL: " -LE:/msys64/mingw64/lib   -Wl,--subsystem,windows -mwindows E:/msys64/mingw64/lib/libwx_mswu-3.1.a -lpng -lz -ljpeg -ltiff -llzma -lwxregexu-3.1 -lwxscintilla-3.1 -lz -lexpat -lpng -lz -ljpeg -ltiff -llzma -lz -lrpcrt4 -loleaut32 -lole32 -luuid -llzma -luxtheme -lwinspool -lwinmm -lshell32 -lshlwapi -lcomctl32 -lcomdlg32 -ladvapi32 -lversion -lwsock32 -lgdi32 -loleacc  ".}
{.passC: " -static-libstdc++ -IE:/msys64/mingw64/lib/wx/include/msw-unicode-static-3.1 -IE:/msys64/mingw64/include/wx-3.1 -D_FILE_OFFSET_BITS=64 -DwxDEBUG_LEVEL=0 -D__WXMSW__  ".}

5. modify richtext.nim

then you can compile all the 4 demos with nim cpp xx.nim
