esql error

I recently install Informix 7.3 on mandrake 10.1 and I'm getting the following error: /home/informix/lib/esql/libifgen.a(decconv.o)(.text+0x12c2): In function `dectodbl': : undefined reference to `errno' /home/informix/lib/esql/libifgen.a(decconv.o)(.text+0x12dc): In function `dectodbl': : undefined reference to `errno' collect2: ld returned 1 exit status I don't have this problem running on mandrake 9.1. Any help would be appreciated. Thanks.
