Re: [Caml-list] ocamlc compiles hello world, ocamlopt not

Hi Xavier,

Thanks for the hint! I gave it a try and also with SYSTEM=bsd_elf. Please, find below the result of the latter (it's the same for linux_elf anyway). I also tried another suggestion from Olivier Andrieu by introducing SYS_minix in asmrun/i386.S but ended up in the same result:( Do you happen to know how to proceed now?

gmake runtimeopt
gmake[1]: Entering directory `/home/r0ller/ocaml-4.00.1'
cd asmrun; gmake all
gmake[2]: Entering directory `/home/r0ller/ocaml-4.00.1/asmrun'

DSYS_bsd_elf: not found

I asked the guys on the minix3 forum and one of the developers said that neither the default minix toolchain (clang) nor the minix port of gcc prepends leading underscores. However, he had a hint about checking if the ocaml package itself is trying to guess during its build whether leading underscore prepending is done on the host system or not.
