Re: [Caml-list] dynamic link library path under mingw

2010-01-27 Thread Xavier Leroy 

I'm doing something wrong, but can't figure out what?


Try setting the OCAMLRUNPARAMS environment variable to the value v=256.
The run-time system will then print additional debug messages
concerning DLL searching and loading.

Why you're not using -dllpath option in ocamlmklib?
I think this should solve your problem (didn't make the check).


I did. With no more success.

I even did it with -verbose, with and without -dllpath: the emitted 
commands are the same


Thanks for your suggestion

P.S. I have the same kind of problem with native code. Is there any way 
to store search path for dynamic libraries in PO/COFF programs?

OCAMLRUNPARAM without S!

Thanks for the tip.

OK. only the paths stored in ld.conf are tried. Testing -I.

This is better:  was found, but can't be loaded?

Maybe because it depends on another library?

depends.exe allow to check that  needs .


[   ] DLLM2MEEPROMS.DLL
 [   ] KERNEL32.DLL
  [   ] NTDLL.DLL
 [   ] MSVCRT.DLL
  [ ^ ] KERNEL32.DLL
   [F^ ] NTDLL.DLL
  [ ^ ] NTDLL.DLL
 [   ] EPROMDLL.DLL
  [ ^ ] KERNEL32.DLL
   [F^ ] NTDLL.DLL



I have the feeling that dllm2mEeproms.dll is loaded explicitely,
but that the load of EpromDll.dll is left to the operating system?


The following works:

If dllm2mEeproms.dll and EpromDll.dll are both in ../libeeproms:

PATH=../libeeproms:$PATH OCAMLRUNPARAM=v=256 ocamlrun -I ../libeeproms 
./tests.byte



If I move EpromDll.dll in ../libeeproms/toto:

PATH=../libeeproms/toto:$PATH ocamlrun -I ../libeeproms tests.byte



Two separated problems, then:
- how to store a search path into tests.byte?
- is it possible to have EpromDll.dll loaded, even if not in a $PATH 
directory?
