C-在cygwin/mingw上为窗户编译

Question

所以，我正在尝试为Cygwin中的开罗图形库编译一个简单的C示例。编译Cygwin时，一切都按预期工作，但是对于Windows编译，但在尝试执行时不起作用。

这是我的makefile：

CFLAGS= -lcairo
#WIN32HEADERS= /usr/i686-w64-mingw32/sys-root/mingw/include/cairo
WIN32HEADERS= /usr/i686-w64-mingw32/sys-root/mingw/include/cairo -I/usr/i686-w64-mingw32/sys-root/mingw/include/glib-2.0 -I/usr/i686-w64-mingw32/sys-root/minclude/glib-2.0 -I/usr/i686-w64-mingw32/sys-root/mlib/glib-2.0/include -I/usr/i686-w64-mingw32/sys-root/minclude/pixman-1 -I/usr/i686-w64-mingw32/sys-root/minclude/freetype2 -I/usr/i686-w64-mingw32/sys-root/minclude/libpng16 -I/usr/i686-w64-mingw32/sys-root/minclude/freetype2 -I/usr/i686-w64-mingw32/sys-root/minclude/libpng16
#WIN32LIBS= ./lib32
WIN32LIBS= ./usr/i686-w64-mingw32/sys-root/mingw/bin
#WIN64HEADERS= /usr/x86_64-w64-mingw32/sys-root/mingw/include/cairo
WIN64HEADERS= /usr/x86_64-w64-mingw32/sys-root/mingw/include/cairo -I/usr/x86_64-w64-mingw32/sys-root/mingw/include/glib-2.0 -I/usr/x86_64-w64-mingw32/sys-root/minclude/glib-2.0 -I/usr/x86_64-w64-mingw32/sys-root/mlib/glib-2.0/include -I/usr/x86_64-w64-mingw32/sys-root/minclude/pixman-1 -I/usr/x86_64-w64-mingw32/sys-root/minclude/freetype2 -I/usr/x86_64-w64-mingw32/sys-root/minclude/libpng16 -I/usr/x86_64-w64-mingw32/sys-root/minclude/freetype2 -I/usr/x86_64-w64-mingw32/sys-root/minclude/libpng16
WIN64LIBS= ./lib64
#WIN64LIBS= ./usr/x86_64-w64-mingw64/sys-root/mingw/bin
CYGWINHEADERS= /usr/include/cairo
CYGWINLIBS= /usr/bin

all:
    i686-w64-mingw32-gcc kairo.c -o kairo_32.exe -I $(WIN32HEADERS) -L $(WIN32LIBS) $(CFLAGS)
    x86_64-w64-mingw32-gcc kairo.c -o kairo_64.exe -I $(WIN64HEADERS) -L $(WIN64LIBS) $(CFLAGS)
    gcc kairo.c -o kairo.o -I $(CYGWINHEADERS) -L $(CYGWINLIBS) $(CFLAGS)
#Build for Windows 32 Bit
win32:
    i686-w64-mingw32-gcc kairo.c -o kairo_32.exe -I $(WIN32HEADERS) -L $(WIN32LIBS) $(CFLAGS)
#Build for Windows 64 Bit
win64:
    x86_64-w64-mingw32-gcc kairo.c -o kairo_64.exe -I $(WIN64HEADERS) -L $(WIN64LIBS) $(CFLAGS)
#Build for Cygwin - maybe linux in general?
cygwin:
    gcc kairo.c -o kairo.o -I $(CYGWINHEADERS) -L $(CYGWINLIBS) $(CFLAGS)
#delete everything but the source files
clean:
    rm *.exe
    rm *.o

我已经尝试了评论的零件以及当前活跃的零件，但没有运气。在尝试执行结果.exe时，我会发现libcairo-2.dll丢失的错误，但是由于它已链接，它不应该找到它吗？是否有任何方法可以链接到非系统文件夹中所需的DLL？我无法弄清楚如何做。

导入lib位于

/USR/I686-W64-MINGW32/SYS-ROOT/Mingw/lib/libcairo.dll.a

因此您需要定义

win32libs =/usr/i686-w64-mingw32/sys-root/mingw/lib
