Hi guys, I am using mingw-w64 gcc v4.8.2 installed under the /mingw32 directory under mingw and I compile using msys/1.0 shell, or CMAKE from msys using "MSYS Makefiles". I adopted this after installing from a recipe and found it worked more often than not in situations where plain mingw/msys (installed on same computer) failed. So I've been pretty happy with things but as my projects get larger I need a better understanding of the general configuration and what gcc expects - especially the linker utilities.
2 quick questions: Is MSYS2 really neccessary to work with mingw-m64 compilers? I've managed OK with msys-1.0. I tried to overlay the 4.9.1 gcc-tools distribution on a /mingw32 tree under my older mingw installation, but the failure of a configure (couldn't determine default exec file) indicates I may need to do something more: true? if so, what? --------------------- My current problem is from trying to make a shared library in graphicsMagick, this line is the first link attempt after compilation: bin/sh ./libtool --tag=CC --mode=link gcc -O2 -mtune=pentium3 \ (more flags) \ -L/local32/lib -o magick/libGraphicsMagick.la -rpath /build32/GM1.3.20share/lib \ (long list of .lo files) \ magick/magick_libGraphicsMagick_la-analyze.lo \ XXX..analyze.lo -lwebp -ltiff -lfreetype -ljpeg -lpng16 -lwmflite -lbz2 -lxml2 -lz -lgdi32 -lm -lgomp -lpthread /bin/grep: /usr/local/lib/libpng16.la: No such file or directory /bin/sed: can't read /usr/local/lib/libpng16.la: No such file or directory libtool: link: `/usr/local/lib/libpng16.la' is not a valid libtool archive ------------------------------------------------------- I'm guessing webp, freetype, jpeg and tiff were ready to load from the compiler tree, and png16 was the first library to get loaded from the library: -L/local32/lib=LDFLAGS holds all of these but it went to search in /usr/local/lib. ???.
