Hi,


I'm having the following problem while porting ocaml using ape/psh:

at one point of the build process (rather early, in fact) it builds a
library called "libcamlrun.a" which contains, among other things, the
definition of main(). this library is then compiled together with a list of
primitives to create the first binary in the bootstrap process -- ocamlrun.

the problem that I'm having is that main() appears to be stripped from the
library (it's contained in main.o), resulting in unsuccessfull compilation:

$ ar vu libcamlrun.a interp.o misc.o stacks.o fix_code.o startup.o main.o  freelist.o major_gc.o minor_gc.o memory.o alloc.o roots.o globroots.o  fail.o signals.o printexc.o backtrace.o  compare.o ints.o floats.o str.o array.o io.o extern.o intern.o  hash.o sys.o meta.o parsing.o gc_ctrl.o terminfo.o md5.o obj.o  lexing.o callback.o debugger.o weak.o compact.o finalise.o custom.o  dynlink.o unix.o
$ make
cc   -o ocamlrun  prims.o libcamlrun.a
_main: undefined: main in _main
cc: 8l: 8l 20157: error
*** Error code 1

Stop.
$

on the other hand including main.o works just fine:

$ make
cc   -o ocamlrun  prims.o libcamlrun.a main.o
$

ar p libcamlrun.a main.o shows 'main' there, fyi..
