Original bug ID: 5655
Reporter: @ygrek
Assigned to: @xclerc
Status: closed (set by @xavierleroy on 2015-12-11T18:07:09Z)
Resolution: fixed
Priority: normal
Severity: minor
Version: 3.12.1
Target version: 4.00.0+dev
Fixed in version: 4.00.0+dev
Category: -for ocamlbuild use https://github.com/ocaml/ocamlbuild/issues
Monitored by: mehdi @hcarty

Bug description

This can be useful for example to pass -verbose flag to see how C compiler is called.

Steps to reproduce

STR:
$ touch src_c.c src.ml
$ echo src_c.o > libsrc_stubs.clib
$ ocamlbuild -classic-display -clean && ocamlbuild -classic-display -cflags -verbose libsrc_stubs.a src.cmx
/usr/bin/ocamlc.opt -c src_c.c
/usr/bin/ocamlmklib -o src_stubs src_c.o
/usr/bin/ocamldep.opt -modules src.ml > src.ml.depends
/usr/bin/ocamlc.opt -c -verbose -o src.cmo src.ml
/usr/bin/ocamlopt.opt -c -verbose -o src.cmx src.ml

  • /usr/bin/ocamlopt.opt -c -verbose -o src.cmx src.ml
  • as -o 'src.o' '/tmp/camlasm5bc13e.s'

ACR:
-verbose is passed only when compiling ml source, but not C source

EXR:
-verbose passed to all invocations of 'ocamlc -c'. NB help says: " -cflag Add to ocamlc compile flags"

Fixed in trunk (revision 12670) and 4.00 (revision 12671) branches.

I might have missed some bit (I didn't check the source, tbh) but isn't the same fix needed for -lflags?

You are right, it cannot hurt (revisions 12675 for trunk, and 12676 for 4.00).
