So I thought I'd change the configure options in PKGBUILD for the CRT to add
--with-default-msvcrt=ucrt
built and installed it. But now when building GCC, I get the following
C:/msys64-redux/mingw64/lib/gcc/x86_64-w64-mingw32/8.3.0/adalib/libgnat.a(argv.o):(.rdata$.refptr.__imp__environ[.refptr.__imp__environ]+0x0):
undefined reference to `__imp__environ'
collect2.exe: error: ld returned 1 exit status
gnatlink: error when calling C:\msys64-redux\mingw64\bin\gcc.exe
gnatmake: *** link failed.
This is not surprising since the GCC I have on the system contains a libgnat
that
uses the older MSVC runtime, which requires the _environ symbol. So I have a
chicken and egg situation here.
Any way around this?
Thanks,
Tom
