Hi Gabriel.
Thanks for the advice. It seems like the Ocaml interpreter installed on my
system was using "flexdll" instead of gcc to do the linking, and "flexdll"
did not understand the "-g" flag. Based on advice provided here (
http://caml.inria.fr/mantis/view.php?id=4645), the option was supposed to be
"-link -g" and not just -g; "-link -g" sends the command "-g" to gcc.
My fix was to change the following portion in "Makefile.ocaml":
ifdef CAML_NOOPT
ifdef WIN32
COMPILE_FLAGS += -ccopt /Zi -ccopt /Od
LINK_FLAGS += -ccopt /Zi -ccopt /Od
else
COMPILE_FLAGS += -g -ccopt -g
ifdef MINGW
LINK_FLAGS += -g
else
LINK_FLAGS += -g -ccopt -g
endif
endif
else
to
ifdef CAML_NOOPT
ifdef WIN32
COMPILE_FLAGS += -ccopt /Zi -ccopt /Od
LINK_FLAGS += -ccopt /Zi -ccopt /Od
else
COMPILE_FLAGS += -g -ccopt -g
ifdef MINGW
LINK_FLAGS += -g
else
LINK_FLAGS += -g -ccopt *"-link -g"*
endif
endif
else
with the changes emboldened (the quotation marks are important). However, I
am not sure what else I have to modify to ensure that this particular change
is only used when "flexdll" is used to link on a system, as opposed to when
gcc is used, because gcc does not understand the "-link -g" command line
option. (I'm new to Makefiles.)
However, I have run into another problem. I get the following error
message:
Linking bytecode obj/x86_WIN32/cilly.byte.exe

'obj/x86_WIN32/cilly.byte.exe' '-L/usr/lib/ocaml' -link -g

** Fatal error: Cannot find file "libstr"
File "_none_", line 1, characters 0-1:

Any suggestions?
Thanks,
Jon.
