Standard libraries not included when using MinGW-w64 GCC #2627
Description
I built c3c entirely from scratch on Windows using MinGW-w64+GCC (under the MSYS2 shell).
But then, when I try to compile a simple C3 test using flags --cc gcc --linker=custom gcc I see the following issues:
- the specified linker is not used (lld-link is used instead of gcc)
- there are undefined symbols related to the standard libraries (maybe due to the above issue)
echo -e "import std::io;\nfn void main()\n{\nio::printn(\"Hello world!\");\n}" |
c3c compile - --cc gcc --linker=custom gcclld-link: error: <root>: undefined symbol: mainCRTStartup
lld-link: error: undefined symbol: _tls_index
