Problem compiling DBD::Informix under Linux

I downloaded and installed Informix SE for Linux (as well as ESQL/C). It seems working like a champ. Awesome. Now I wanted to build perl DBD::Informix. Yes, I read the README. I downloaded and built DBI OK but when I try to compile DBD::Informix I get: ================================================== Configuring DBD::Informix version 0.60... You are using DBI version 1.00 and Perl version 5.00404 Remember to actually read the README file! Using INFORMIX-ESQL Version 7.24.UC5 from /usr/informix DBD::Informix doesn't check whether ODBC or Informix-CLI software is installed any more. It uses a home-brew odbctype.h instead. Testing whether your Informix test environment will work... cc: /usr/informix/lib/libnetstub.so: linker input file unused since linking not done cc: /usr/informix/lib/libnetstub.so: linker input file unused since linking not done /usr/informix/lib/esql/libixos.so: undefined reference to `crypt' Failed to link test program esqltest =================================================== I am doing this under Redhat 5.1. I know that the supported versions are Caldera and Suse (Suse should be here tomorrow although I hate to reinstall if I can get this working). Any help appreciated. -- =================================================== Darrel L. Davis darreld@his.com Linux - The choice of a Gnu generation ===================================================
