According this manual I have installed i686-w64-mingw32. When I try to run a compiled program, I get an empty output. USE="-fortran" crossdev -t i686-w64-mingw32 --stable -oO /usr/crossdev-overlay Example: $ cat hello.cpp #include <iostream> using namespace std; int main() { cout << "Hello, World" << endl; return 0; } $ i686-w64-mingw32-g++ -O2 hello.cpp -o hello.exe -mconsole -static-libgcc -static-libstdc++ $ wine hello.exe $

Assuming workaround does help: https://www.linux.org.ru/forum/development/13966748?lastmod=1516422156800&filter=show#comment-13968613 It means mingw startup code is not compatible with --enable-default-pie. To avoid passing -no-pie into every linked program you can disable gcc[pie] as: $ USE="-pie" crossdev -t i686-w64-mingw32 or override default in /etc/portage/package.use/cross-i686-w64-mingw32

Looks like x86_64-w64-mingw32 needs the same fix, otherwise it also produces executables that just hang.

Yes, with USE=-pie the resulting x64 executables work fine (tested on GIMP 2.10)

Thanks for the report and test! crossdev-20180508 should default to saner toolchain now.
