Hi to all the MSYS2 community,
At first MSYS2 is the solution i have search for years for making
Windows version from my programs, passing trough code-block-mingw32,
mingw alone, cygwin,...
---
But i come to my problem:
I can compile and launching my program mmp-2.1 which is an update from
the Micro Music Player
<http://www.open-source-projects.net/Micro_Music_Player/Micro_Music_Player_presentation.html>
which I have build for Linux, the update will soon release in the hope
their will be a Windows version too.
:: extract from my Makefile
CXXFLAGS= -mwindows-O2-std=c++11 # we can try -static-libstdc++ -static-libgcc -lstdc++ # but -lmingw32
make fail the build
LDFLAGS= `pkg-config--cflags gtk+-3.0` `pkg-config--cflags libvlc`
LDFLAGS= `pkg-config--libs gtk+-3.0` `pkg-config--libs libvlc`
All success but when i come to distributing i heart to a wall:
I have make a folder outside from the MSYS2 installation, then copy all
the dependencies, and finally copy the required *.dll files into my
./bin folder like this
::
ldd ./bin/mmp | grep mingw64 | cp $(gawk '{print $3}')
/path/to/test/dir/bin
And when i launch the program all works fine except the initialization
from libvlc which always return NULL ???
::
int main (int argc, char *argv[]) {
// ...
libvlc_instance_t * libvlc_inst = libvlc_new (0, NULL) ;
if (libvlc_inst == NULL) {
// The instance is always equal to NULL in the
/path/to/test/dir/bin
// But not in the MSYS2 home ???
fprintf(stderr,"The unborn is killed in the winbee !\n") ;
exit(EXIT_FAILURE) ;
}
// ...
return 0 ;
}
Thanks for you answers about why my program works into the MSYS
environment and not other way ?
I think the problem is the libvlc because the program start but libvlc
doesn't initialize.
PS: Is it right to distribute only the *.dll contains into the /mingw64
subfolders or must I add the *.dll from /c/windows too ?
