无法将'timeval *'转换为'PTIMEVAL {aka __ms_timeval *}'

Question

在Windows10 / MSYS2 / Cygwin上FileZilla的wxWidgets编译期间出现此错误。

  

$ ./configure --prefix =＆＃34; $ HOME / prefix＆＃34; --enable-static --disable-shared   --build = x86_64-w64-mingw32 --enable-unicode --without-libtiff --without-libjpeg --with-expat = builtin --with-libpng = builtin --disable-fsvolume

$ make

Google搜索提供了一些暗示，它与提升有关。 有办法解决吗？

Answer 1

Both values are different structures, because the members are of different type. Look at the definition code of them.

You cant convert them => make an instance and set the members.
