[melroy89]

Cross-compiling towards Windows, on Linux, with gcc11 (using MXE.cc project).

With your latest release:

Within the MXE.cc project we switched to GCC11 now, but this should work.

The command I used after updating your project to again the latest release:

-$(PKG)_VERSION  := 64989f6
-$(PKG)_CHECKSUM := 7b9844bf3af80191a850bb3ef3c3e1a451dbca6b8441d5094a2a6260afb414b7
+$(PKG)_VERSION  := ff4f844
+$(PKG)_CHECKSUM := 21a7134ca60ad8ff4e75e839999acf9ae6992d07d2d826fa783005a4dd0263ca

Anyway, the command I used:

sudo make pe-parse -j 16 MXE_TARGETS='x86_64-w64-mingw32.static' MXE_PLUGIN_DIRS='plugins/gcc11'

@ekilmer maybe create a new release :)?

[woodruffw]

Thanks for bringing this to our attention. I'll cut a 2.0.0 release now.

[woodruffw]

Alright, we've cut the latest changes as 2.0.0. Let me know if you have any issues and we'll reopen here!
