Undefined references to utf8proc_* when building julia from source on mingw32

[ajinkya-k]

Building julia from source fails on mingw32 possibly because utf8proc library is missing. Note that this error does not occur for mingw64, but happens only on 32bit

can someone help with this?

[giordano]

Build with make ... VERBOSE=1 to show the compiler invocation, otherwise it's impossible to say anything.

[ajinkya-k]

this might have happened because the julia directory was not clean. I will try to build from a clean directory again.

There is something wrong with libutf8proc.a, seems a version mismatch.

[vtjnash]

It looks like it is using the wrong compiler (host gcc). Only cross-compiler (XC_HOST-gcc) is supported on Windows.

[ajinkya-k]

@vtjnash do you mean only cross compilation using cygwin is supported?

[vtjnash]

msys2 is also mostly supported, though it presents itself as an odd sort of native cross-compiler, which can get you into some trouble when trying to build things if you don't force it to operate as a normal cross-compiler

[ajinkya-k]

Given that using msys2/mignw is brittle, maybe the msys2/mingw section should be removed from the build doc?

[ajinkya-k]

For what its worth, in a clean directory the build worked, using this PR #57451
