Hello, I am creating a GUI for my science project, using FLTK.
The CodeBlocks default "GNU GCC Compiler" works fine.
Then I wanted to compile exe for my program for Windows use.
Add new compiler... check
Directories set to /usr/x86_64-w64-mingw32/include (compiler), /usr/x86_64-w64-mingw32/lib (linker) and /usr/x86_64-w64-mingw32/include (resource compiler)
Toolchains executables set to x86_64-w64-mingw32-gcc, x86_64-w64-mingw32-g++, x86_64-w64-mingw32-g++, x86_64-w64-mingw32-g++.

They are mostly warning from FLTK.
But THIS:
ld||unrecognized option '-z'|
||error: ld returned 1 exit status|
stops me from rebuilding it, thus cannot have EXE file.
What is this? Searching gives me no answer.
Some more info: the rebuild code from codeblocks:
x86_64-w64-mingw32-g++ -I/usr/include/freetype2 -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fvisibility-inlines-hidden -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT -g -I../../../../../home/kudy/Downloads/fltk-1.3.3 -I/usr/x86_64-w64-mingw32/include -c /media/DATA/Projects/FLTK/cap2_gui/main.cpp -o obj/Debug/main.o
the sucessful default rebuild (before cross compiling):
g++ -I/usr/include/freetype2 -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector-strong -fvisibility-inlines-hidden -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -D_THREAD_SAFE -D_REENTRANT -g -I../../../../../home/kudy/Downloads/fltk-1.3.3 -c /media/DATA/Projects/FLTK/cap2_gui/main.cpp -o obj/Debug/main.o
g++ -L../../../../../home/kudy/Downloads/fltk-1.3.3/lib -o bin/Debug/cap2_gui obj/Debug/main.o -Wl,-O1,--sort-common,--as-needed,-z,relro -lGL -lGLU -Wl,-O1,--sort-common,--as-needed,-z,relro -lGL -lGLU ../../../../../usr/lib/libfltk_images.so ../../../../../usr/lib/libfltk_gl.so ../../../../../usr/lib/libfltk.so ../../../../../usr/lib/libfltk_forms.so
Other linker options:
`fltk-config --ldstaticflags`
-lGL -lGLU
remove these lines clears ld||unrecognized option '-z'| but still returns 1.
