我尝试运行一个依赖于 .dll 的 Windows 程序，而 .dll 既不在当前目录中，也不在程序目录中。文档中提到，“WINEDLLPATH”变量用于提示在何处搜索库。但即使设置了此变量，我也无法运行该程序：
/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.
fixme:winediag:start_process Please mention your exact version when filing bug reports on winehq.org.

open("/opt/qt/win32/qt/5.6/mingw49_32/bin//libwinpthread-1.dll.so", O_RDONLY|O_LARGEFILE) = -1 ENOENT (No such file or directory)
最让人恼火的是最后两行。/opt/qt/win32/qt/5.6/mingw49_32/bin//libwinpthread-1.dll.so如果没有后缀， Wine 会尝试打开 ，而这应该是正确的文件.so。
有没有办法让 wine 以/opt/qt/win32/qt/5.6/mingw49_32/bin/对待 $PWD 或程序目录中的文件相同的方式考虑 .dll 文件？
答案1
我发现，wine 提供了 -variable WINEPATH，它添加了额外的路径来查找其他库。
WINEPATH=/opt/qt/win32/qt/5.6/mingw49_32/bin/ /opt/qt/win32/qt/Tools/mingw492_32/libexec/gcc/i686-w64-mingw32/4.9.2/cc1.exe --help
确实有效。
