I'm using the MinGW version of OCaml 3.11.0 under Cygwin to build a
custom-linked executable. The command
ocamlc -custom -o foo.exe foo.ml
produces the rather cryptic error message
Access is denied.
** Fatal error: hd
File "_none_", line 1, characters 0-1:
Error: Error while building custom runtime system
This problem has a simple solution: Cygwin allows multiple versions of
gcc to coexist by making /usr/bin/gcc.exe a symlink
to /etc/alternatives/gcc, and making another symlink from there
to /usr/bin/gcc-3.exe. The flexdll tool that's used to link OCaml
programs won't tolerate this. So you need to remove the
symlink /usr/bin/gcc.exe and copy /usr/bin/gcc-3.exe in its place. Then
everything works as it should.
Seasonal best wishes to all!
