Description John Ellson 2012-06-10 10:47:30 EDT
Description of problem:

Graphviz builds fail with:

gv_ocaml.cpp:866:54: error: declaration of C function 'int caml_array_length(caml_value_t)' conflicts with
In file included from /usr/lib64/ocaml/caml/alloc.h:24:0,
                 from gv_ocaml.cpp:752:
/usr/lib64/ocaml/caml/mlvalues.h:252:21: error: previous declaration 'mlsize_t caml_array_length(caml_value_t)' here

swig generated the gv_ocaml.cpp with:
    SWIGSTATIC int caml_array_length( CAML_VALUE arr );

mlvalues.h expects:
    CAMLextern mlsize_t caml_array_length (value);   /* size in items */

This is only a problem on x86_64;  no eror on i686.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1.  build graphviz (I'm building upstream development snapshots, but ocaml code hasn't changed recently so I expect this will effect the Fedora version too.)
Actual results:
compile errors as above

Expected results:
no compile errors

Additional info:
Only affects x86_64
Comment 1 John Ellson 2012-06-11 09:23:14 EDT
Correction - also affects i686 (build must have run before upgrade yesterday, sorry)
Comment 2 Adam Tkac 2012-06-12 06:40:01 EDT
I untagged broken swig from f18-build collection so you should be able to compile ocaml successfully now. The patch for swig is on the way...
Comment 3 Adam Tkac 2012-06-19 07:01:17 EDT
It seems this was a bug in ocaml package, I'm not able to reproduce this bug with swig-2.0.7-1 now.

Closing as notabug, please reopen it if problem still persists.
