The missing function finite() is called from an Informix library and I found it neither in 10.20- nor in 11.11-systemlibraries. I tried your hint to create a dummy function for finite(), but now the shared library loader complaints about another missing funtion. A test program with ESQL functions originally produced the following error message: # make making all in ./src... if [ -f infxtest ]; then rm -f infxtest~; mv -f infxtest infxtest~; fi cc -o infxtest -g -Aa +DAportable -Wl,-aarchive_shared -L /opt/informix/lib/esql -L/opt/informix/lib infxtest.o libDB.a -lsql -los -lasf -lgen -lixgen -lixgls -lixglx -lixos -lixsql -lxti -lm -ldld -lsec /usr/ccs/bin/ld: Unsatisfied symbols: finite (first referenced in /opt/informix/lib/esql/libgen.a (rvaldata.o)) (code) *** Error exit code 1 With your proposed dummy function the test program compiles, links and runs without problems. My next step was to install the DBD-Informix PERL module. With shared libraries the module compiles fine, but 'make test' produces the error: PERL_DL_NONLAZY=1 /usr/bin/perl "-MExtUtils::Command::MM" "-e" "test_harness(0, 'blib/lib', 'blib/arch')" t/t00basic.t t/t01stproc.t ... t/t00basic........../usr/lib/dld.sl: Unresolved symbol: finite (code) from /opt/informix/lib/esql/libifgen.sl install_driver(Informix) failed: Can't load '/home/ascapp/DBD-Informix- 2003.04/blib/arch/auto/DBD/Informix/Informix.sl' for module DBD::Informix: No such file or directory at /opt/perl5/lib/5.8.6/PA- RISC2.0-thread-multi/DynaLoader.pm line 230. at (eval 1) line 3 Compilation failed in require at (eval 1) line 3.

FAILED tests 1-41 Unfortunately it is no option for us to use a 64bit CSDK (Perl is running as 32bit application, and we really don't want to know which modules will fail when using 64bit mode) Thanks a lot for your help.
