Question

所以，我正在尝试为cygwin中的cairo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

我已经尝试了注释掉的部分，以及当前活跃的部分，但没有运气。当尝试执行生成的.exe时，我收到一个错误，即libcairo-2.dll丢失了，但它不应该能够找到它，因为它是链接的？有没有办法在非系统文件夹中链接到所需的dll？我无法弄清楚如何做到这一点。

导入库位于

/usr/i686-w64-mingw32/sys-root/mingw/lib/libcairo.dll.a

所以你需要定义

WIN32LIBS =的/ usr / i686的-W64-的mingw32 / SYS-根/的mingw / lib中

在cygwin / mingw上编译windows
