Subject: [Caml-list] Options -c and -o are incompatible when compiling C files
Date: Tue, 18 Jul 2017 14:22:17 +0200 [thread overview]
Message-ID: <546b87d1-9f90-684a-b048-c8ffb279ff7b@glondu.net> (raw)
Hello,
kalzium (in Debian) fails to build with ocaml 4.05.0 because of the
following error:
> [ 55%] Generating modwrap.o
> cd /tmp/kalzium-16.08.3/obj-x86_64-linux-gnu/src && /usr/bin/ocamlopt -I /usr/lib/ocaml/facile -c /tmp/kalzium-16.08.3/src/solver/modwrap.c -o /tmp/kalzium-16.08.3/obj-x86_64-linux-gnu/src/modwrap.o
> Options -c and -o are incompatible when compiling C files
> src/CMakeFiles/kalzium.dir/build.make:107: recipe for target 'src/modwrap.o' failed
> make[4]: *** [src/modwrap.o] Error 2
> make[4]: Leaving directory '/tmp/kalzium-16.08.3/obj-x86_64-linux-gnu'
> CMakeFiles/Makefile2:305: recipe for target 'src/CMakeFiles/kalzium.dir/all' failed
> make[3]: *** [src/CMakeFiles/kalzium.dir/all] Error 2
I am surprised by this error message: what is the rationale?
Investigating this, I bumped into:
https://github.com/ocaml/ocaml/pull/761
Fabrice says: "In 4.04.0+beta1, ocamlc -c test.c -o subdir/test.o does
not produce subdir/test.o but test.o.". But in ocaml 4.02.3, -c and -o
used to work properly together (kalzium was building successfully). This
looks like a regression to me.
