POcompiling BUTT with mingw64 cannot convert 'char*' to ' LPWSTR {aka wchar_t*}' in assignment
text
Body
copied!<p>I'm trying to compile BUTT (<a href="http://butt.sourceforge.net/" rel="nofollow">http://butt.sourceforge.net/</a>) on windows with MingwW64. I seem to be running into errors of the type <code>error: cannot convert 'char*' to 'LPCWSTR {aka const wchar_t*}'</code> the most. Is there some simple option for enabling unicode that I am missing? You can see the options being passed to g++ at the top of my paste.</p> <pre><code>0_0@0_0-PC /z/src/butt-0.1.12 $ make make -C src check for ../config.mk ... ok. make[1]: Entering directory `/z/src/butt-0.1.12/src' g++ -I/usr/local/include -I/usr/local/include -I/usr/local/include -I. -I/usr/ local/include -Wall -O2 -DVERSION=\"butt-0.1.12\" `` -IFLTK -I/usr/local/includ e -I/usr/local/include/FL/images -mwindows -DWIN32 -DUSE_OPENGL32 -D_LARGEFILE_S OURCE -D_LARGEFILE64_SOURCE -D_FILE_OFFSET_BITS=64 -DFLTK1 -DHAVE_FLTK -ILIBVORB IS -DHAVE_LIBVORBIS -ILIBLAME -DHAVE_LIBLAME -c -o FLTK/Fl_Native_File_Cho oser.o FLTK/Fl_Native_File_Chooser.cpp In file included from FLTK/Fl_Native_File_Chooser.cpp:26:0: FLTK/Fl_Native_File_Chooser_WIN32.cxx: In member function 'void Fl_Native_File_C hooser::ClearOFN()': FLTK/Fl_Native_File_Chooser_WIN32.cxx:244:24: error: cannot convert 'char*' to ' LPWSTR {aka wchar_t*}' in assignment _ofn.lpstrFile = strfree((char*)_ofn.lpstrFile); ^ FLTK/Fl_Native_File_Chooser_WIN32.cxx:247:30: error: cannot convert 'LPCSTR {aka const char*}' to 'LPCWSTR {aka const wchar_t*}' in assignment _ofn.lpstrInitialDir = (LPCSTR)strfree((char*)_ofn.lpstrInitialDir); ^ FLTK/Fl_Native_File_Chooser_WIN32.cxx: In member function 'int Fl_Native_File_Ch ooser::showfile()': FLTK/Fl_Native_File_Chooser_WIN32.cxx:312:23: error: cannot convert 'char*' to ' LPWSTR {aka wchar_t*}' in assignment _ofn.lpstrFile = new char[fsize]; ^ FLTK/Fl_Native_File_Chooser_WIN32.cxx:319:21: error: cannot convert 'char*' to ' LPCWSTR {aka const wchar_t*}' in assignment _ofn.lpstrTitle = _title ?
