And are pa8700 at 875mhz...

Have the problem also on 11.00...

When try to compile php in apache2 (--enable-mods-shared for apache + 
--with-apxs2 for php) module, with php module (--enable-shared), the problem is 
libtool does not correctly detect dependency, and arbitrary decide to link 
static....

When force pass_all libtool linking work perfectly...if I use only .sl in 
dependency... 

If y try to generate .sl linked with static lib they don't whant...but are 
other problem...

Have dependency like that: httpd, that open libphp4.sl, that open oci8.sl, that 
open libclntsh.sl that open many other oracle libs....


And with that modification all other compilation with dll work for me without 
probleme...

Have tested test_compile mode without success...

But I don't have many time to test... I think is the shell script who make 
file_magic mode who fail to find dependency... if have time I while try to 
debug this shell script why don't find dependency...

I don't use 64bit at all... I use gcc in 32bit only... binary versions of gcc 
in 64bit mode are very problematic at the moment...and binary version of open 
source a only in 32bit mode for the moment for hp-ux...And mixing 64bit with 
32bit is a little bit touchy!!!!

Gnu ld for 32bit does not exist... only for 64bit version... I use hp-ux ld...

I don't have ia64 for the moment for testing... but in future it's possible to 
have... and I while try it...

For "hppa*64" I don't know witch machine and os send this matching.....!!!!
