I'm unable to build OCaml using the mingw-w64 compilers with Cygwin 3.2.0.
Windows 10.0.19042.928 (and tried on three different machines so far)
Repro:
- Fresh Cygwin64 installation with make, libiconv, mingw64-x86_64-gcc-core
and git added; fire up mintty
- git clone --depth 1 --recursive https://github.com/ocaml/ocaml
- cd ocaml && ./configure --host=x86_64-w64-mingw32 && make -j8 flexdll &&
make -j8 world.opt
This is consistently hanging with Cygwin 3.2.0 and seems possibly to have
something to do with linking (the creation of runtime/ocamlrun.exe and
stdlib/camlheader, which is also an executable, seem to be part of the
problem).
It can be immediately fixed by downgrading to Cygwin 3.1.7, cleaning the
tree and repeating the build.
I'm of course very happy to try to reduce this to a smaller repro case, but
is there an obvious culprit in Cygwin 3.2.0 to check before I do?
The build fails for me with error messages but it does not hang.
You could have tried at least building without -j option, and running
the build steps separately for better diagnostics.
Many thanks,
David
