You said earlier that you don’t know which version of MinGW you’re using, so I
think there’s a good chance that you can’t reproduce the problem because you
two are not agreeing on what “MinGW” means.
(No surprise, the MinGW project has forked roughly thrice (original mingw32,
MSYS, MSYS2, MingW-64) and the original project has been through several
changes of maintainership besides.)
The installation directory quoted in the OP’s build transcript tells us much:
x86_64-5.3.0-win32-seh-rt_v4-rev0
Splitting by dashes, it means:
* x86_64: target CPU type
* 5.3.0: GCC version, which is fairly old (7.2.0 is current from MinGW)
* win32: refers to threading model; alternative is “posix”.
* seh: use Windows native Structured Exception Handling, as opposed to dwarf
(32-bit only) exceptions or exceptions implemented in terms of setjmp/longjmp,
a.k.a. “sjlj”.
* rt_v4: MinGW runtime version; current is 5.0.3, reported as “rt_v5”
* rev0: first build of 5.3.0; there only was rev0 for this version
So, I’d suggest that you two get onto the same page and work from there. :)
This is the current source for MinGW-64 binary builds:
https://mingw-w64.org/doku.php/download/mingw-builds
I tried building using win/Makefile.mingw* under
x86_64-7.2.0-win32-seh-rt_v5-rev1 and get a bunch of complaints about the
assembly code in zlib. I haven’t bothered trying to roll back to 5.3.0 to see
if that helps.
Another MinGW flavor that may be of interest is the Cygwin package, since it
means you can use POSIX tools to build, yet get a Cygwin-free binary out. In
theory. :)
