Crosscompiling ECL for Windows

[Wolfgang Dautermann]

Dear ECL-developers,

Can one crosscompile ECL for Windows (on a Linux based system)?
Currently it fails - both the latest release and the current GIT - with:


$ ./configure --host=i686-w64-mingw32
$ make
[...]
i686-w64-mingw32-gcc -DECLDIR="\"/usr/local/lib/ecl-16.1.2\"" -I.
-I/tmp/ecl/build -I/tmp/ecl/src/c -I../ecl/gc -DECL_API -DECL_NO_LEGACY
   -g -O2 -D_THREAD_SAFE -Dmingw32 -c -o threads/process.o
threads/process.o.c
/tmp/ecl/src/c/threads/process.d:40:22: error: conflicting types for

make: *** [all] Error 2

What is the problem here?

(Background: I developed a crosscompiled Windows installer for the (Lisp
based) computer algebra system 'Maxima' (using 'Wine' (does ECL work
with the emulator 'wine'?)), currently based on CLISP and SBCL - and
probably I can support ECL too - but for that I should be able to
crosscompile it.
