[Expat-discuss] Re: troubles with expat sol 8/gcc/xml-parser

[Josh Martin]

Hi,

Ah, see, there's the rub.  If you're writing an extension for Perl (at least in 
C) then you must either build it as a dynamic library, or you have to have to 
statically link it in to perl itself, meaning recompiling perl. Now, I'm rather 
vague on static versus dynamic libraries on solaris, but I think it should be 
possible to build the XML-Parser module dynamically (as normal) but link the 
expat library into it statically when you build it.  That is, assuming you only 
built a static version of expat.  You might (but shouldn't) need to get so 
drastic as to edit the XML::Parser makefile and add the '-lexpat' compiler 
switch (possibly along with the '-L' compiler switch specifying the directory 
expat was installed to if it's not in your libpath).

BTW, Perl version 5.6.1 is the most recent stable release.  As far as I could 
tell there is no version 5.8.  Okay, I take that back... 5.8 is the most recent 
release.  While it is not the "stable" release, it is also not a development 
release, so that shouldn't be causing you any problems.  You might want to check 
the perldelta man page (or perldoc) just to be sure.  Also, did you try running 
'make test' after 'make install' like I suggested? Did it help?
