Bug #3386 Unresolved symbol: ifx_checkAPI
Submitted: 2000-02-02 09:55 UTC Modified: 2000-10-05 06:41 UTC
From: petr dot husak at meiller dot com Assigned: afalout (profile)
Status: Closed Package: Informix related
PHP Version: 4.0 Beta 3 OS: hpux 10.20
Private report: No CVE-ID: None
 [2000-02-02 09:55 UTC] petr dot husak at meiller dot com
When I use function ifx_connect(), httpd instance crashes and in the logfile appears record:

/usr/lib/ Unresolved symbol: ifx_checkAPI (code)  from /apl/informix/lib/

I use Iformix SE 7.22 and Inf. client sdk v2.40 uc11.
I've compiled php4 with informix support and the phpinfo() shows information about the informix extension well.

Actually, not close yet. It should be in "Assigned', not 'Feedback'...

Has there been any progress on this bug?

I was examining an option to add described statemens to makefiles but after taking in account differences between CSDK, ESQL/C in different versions, I gave up. It seems that Informix spend half of there time renaming files in new versions. Just adding checkapi.o  should work, but location of that file changes trough versions too. Then, I noted that there are simmilar problem caused and fixed the same way, that do not nececery relate to checkapi.o in error message.

This information should be sufficient for users to resolve this issue. It should go to FAQ or manual or somewhere.

Closed. For real this time...I hope.

I added additional comments to this workaround from Danny that apply to libtool in V4:

The work-around suggested by Andrej is still valid, but libtool does not
like those "libifsql.a libifasf.a ..." libraries, you have to specify them
as '-lifsql -lifasf ...' etc..

This will use the shared (.so) libraries, which is not a problem (unless you
move the binary to another machine with a different Informix server or
client version, in that case you should use the static libraries). If you
need the static Informix libraries, copy them to a separate directory and
add that directory to your $LDFLAGS when running configure for PHP and for
Apache, this way the linker won't find the shared libraries and use the
static ones. This is the way I build Apache/modphp4 because I have to
distribute the binary to SVR4  Unix servers running different Informix
server versions (7.21, 7.22, 7.23, 7.30 and 7.31).

This may help somebody who is not so much in the stuff (like me) If you have to struggle with Apache,Informix and PHP installation troubles, have a look at this install-solution wich solved my problems in september 2002
Thanks to Paul Gardiner again, who helped me in further informix-problems, i could adjust his script for the actuall versions of HP-UX and INFORMIX.
