LinuxQuestions.org - URGENT: help with Makefile

Hello all,

I have this Makefile (see the bottom of this message) that works fine in Unix, but is giving me problems in Linux. The message that I keep getting is:

/home/informix/bin/esql -O -o DbUpdate_inf -I. -I/home/informix/incl/esql -I/homes/rogerh/dbupdate/inflib/rel6.1 main.o error.o inf/DbUpdate.o inf/db_err.o inf/DbUpdate_6.o inf/create_procedure.o -L /homes/rogerh/dbupdate/inflib/rel6.1 -ldb_genlib -lm
/usr/bin/ld: cannot find -ldb_genlib
collect2: ld returned 1 exit status
make: *** [linux] Error 1

Although db_genlib.a is found in ${IDSDBLIB}/inflib/rel6.1
(IDSDBLIB is defined, verified and all that. ls -l ${IDSDBLIB}/inflib/rel6.1/db_genlib.a produces the right file with read/write permissions to all).
And it's driving me nuts.. I tried copying the library (db_genlib.a) to the current directory and typing -l./db_genlib, still didn't work. Tried all combinations (db_genlib, db_genlib.a).

What is missing here?!

Thank you so much!!!
