Hello.
I'm trying to build a .cma with C stubs with ocamlbuild. Linking and
includes are supposed to be set to non-standard directories.
You probably need to add some 'A-ccopt; Ayour-option' to the good
tag.
Can you give more details/actual layout of your myocamlbuild.ml ?
OK. Yes, I could meddle with my myocamlbuild.ml file. My myocamlbuild.ml
file is the same as the one on the wiki:
http://brion.inria.fr/gallium/index.php/Using_ocamlfind_with_ocamlbuild
But I mean, if I'm supposed to write a myocamlbuild.ml for every project
I make, I might as well use Makefiles, as below.
I was wondering if there was a myocamlbuild.ml that would solve the C
stub problem and bottleneck. For instance, being able to _tag in the
tags file for a given .c file the directories in which to look for
headers (here /usr/share/R/include), and for .o files, all linking
information (here, /usr/lib/R/lib/libR.so).
The ideal would be to have all that available only from _tags.
Because if you need to write a myocamlbuild.ml for each and every
project, you might as well write Makefiles... That's the point of a
generic plugin.
