Question

我正在尝试从Eclipse进行CPP开发..

我已经安装了cgywin ..当尝试编译时，链接任何简单的Hello World应用程序，我在链接时得到以下内容...

/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -luser32
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lkernel32
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -ladvapi32
/usr/lib/gcc/i686-pc-cygwin/3.4.4/../../../../i686-pc-cygwin/bin/ld: cannot find -lshell32

完整输出：

***Build of configuration Debug for project testcpp***

**** Build Finished ****

我认为ld所需的上述库是特定的赢...

我试过find / -name *user32*，结果是..

.....
/usr/i686-pc-mingw32/sys-root/mingw/lib/libuser32.a
......

这有用吗？

Answer 1

从上面的通知中：

I've tried find / -name *user32*, the result were ..

.....
/usr/i686-pc-mingw32/sys-root/mingw/lib/libuser32.a
......

Is this can help?

这对我有帮助..

所需的库包含在mingw下，但我在eclipse中使用cygwin。所以，在cygwin的目录下是： /usr/i686-pc-cygwin，我做了以下事情： ln -sf ../i686-pc-mingw32/sys-root/mingw/lib lib; 所以，现在cgywin拥有所需的库......

我意外中断了设置，并开始看到这些：

/usr/lib/gcc/x86_64-pc-cygwin/4.8.3/../../../../x86_64-pc-cygwin/bin/ld: cannot find -lshell32
/usr/lib/gcc/x86_64-pc-cygwin/4.8.3/../../../../x86_64-pc-cygwin/bin/ld: cannot find -luser32
collect2: error: ld returned 1 exit status

跑"cygcheck -c"导致一切正常

Ran "cygcheck -p libuser32.a"并看到两个命令输出之间的重叠

Found 9 matches for libuser32.a
cygwin32-w32api-runtime-3.1.0-1 - Win32 API import libs for Cygwin 32bit toolchain
cygwin32-w32api-runtime-3.2.0-1 - Win32 API import libs for Cygwin 32bit toolchain

w32api-runtime-3.2.0-1 - MinGW-w64 Windows API import libraries for Cygwin
w32api-runtime-3.3.0-1 - MinGW-w64 Windows API import libraries for Cygwin

重新安装w32api-runtime再次设置设置并解决问题。
