我尝试运行一个 Windows 程序，它依赖于一个 .dll，它既不在当前目录中也不在程序目录中。该文档提到“WINEDLLPATH”变量用于提示在何处搜索库。但是即使设置了这个变量，我也无法运行程序：
/home/rudi/foobar $ WINEDLLPATH=/opt/qt/win32/qt/5.6/mingw49_32/bin/ strace -o /tmp/cc1.log /opt/qt/win32/qt/Tools/mingw492_32/libexec/gcc/i686-w64-mingw32/4.9.2/cc1.exe --help
fixme:winediag:start_process Wine Staging 1.9.12 is a testing version containing experimental patches.
