ld 找不到 找不到 -luser32 （来自 Eclipse）

Question

我正在尝试从 Eclipse 进行 CPP 开发..

我已经安装了 cgywin..并且当尝试编译时，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 ****

I认为 ld 所需的上述库是 win 特定的...

我尝试过 find / -name *user32*，结果是..

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

这有帮助吗？

Answer 1

从上面的通知来看：

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

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

Is this can help?

它确实帮助了我..

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

Answer 2

我意外中断了安装，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

Ran "cygcheck -c" 结果一切正常

Ran "cygcheck -p libuser32.a" 并看到两者之间有重叠命令输出

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

通过重新安装 w32api-runtime 再次运行设置并解决问题。
