I'm getting this error on a g++ build step:
g++ -L/sw/lib/ -o dlllablscintilla.so ml_scintilla.o
liblablscintilla.a "/usr/local/godi/lib/ocaml/std-lib"/libcamlrun.a
"/usr/local/godi/lib/ocaml/std-lib"/lablgtk2/liblablgtk2.a
-lgtk-x11-2.0 -lgdk-x11-2.0 -latk-1.0 -lgdk_pixbuf-2.0 -lm
-lpangoft2-1.0 -lpango-1.0 -lfreetype.6 -lgobject-2.0 -lgmodule-2.0
-ldl -lglib-2.0 -lgthread-2.0
/usr/bin/ld: Undefined symbols:
_caml_names_of_builtin_cprim
_caml_builtin_cprim
It may or may not be a coincidence, but I'm trying to build your
lablscintilla package. This is on OS X 10.4 with godi-installed OCaml
3.09.3. FWIW, these symbol references appear to come from
libcamlrun.a. They don't appear in libasmrun.
[n8gray@golux n8gray]$ nm -a
/usr/local/godi/lib/ocaml/std-lib/libcamlrun.a | grep builtin_cprim
U _caml_names_of_builtin_cprim
U _caml_builtin_cprim
U _caml_names_of_builtin_cprim
[n8gray@golux n8gray]$ nm -a
/usr/local/godi/lib/ocaml/std-lib/libasmrun.a | grep builtin_cprim
Building the native-code version works fine.
Cheers,
