Hello
I try to use Interbase Client with PHP to work with an interbase database. 
I work on Solaris 8, with php 5.1.4 and apache 2.0.55.
So, i have to recompile my php with the option: "--with-interbase=shared,/opt/app/apache/SoftAnx/Interbase/7.5"
The compilation fails with the following error message :
...
checking for isc_detach_database in -lib_util... no
configure: error: libgds, libib_util or libfbclient not found! Check config.log for more information 

In the config.log, I has the following error :
...
configure:49496: checking for isc_detach_database in -lib_util
configure:49515: gcc -o conftest -I/usr/local/include -g -O2  -D_POSIX_PTHREAD_SEMANTICS -R/opt/app/apache/SoftAnx/Interbase/7.5/lib -L/opt/app/apache/SoftAnx/Interbase/7.5/lib -liconv -L/usr/local/lib  -R/usr/ucblib -L/usr/ucblib -R/usr/local/lib/gcc/sparc-sun-solaris2.8/3.4.2 -L/usr/local/lib/gcc/sparc-sun-solaris2.8/3.4.2 -R/usr/local/lib -L/usr/local/lib conftest.c -lib_util  -liconv -lresolv -lm -ldl -lnsl -lsocket  -lgcc -lxml2 -lz -liconv -lm -lsocket -lnsl -lxml2 -lz -liconv -lm -lsocket -lnsl 1>&5

/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply.  */
char isc_detach_database(

The 3 libraries are wel installed and my LD_LIBRARY_PATH is correct...

Thanks for help
