Shared libray error at application start

----LNX_Fri_May_16_2003_17:50:31_V3.33-- Content-Type: text/plain; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable Hello, = we have an ESQL/C application developed with Client SDK 2.50 and running against 9.30.HC2 first and against 9.30.HC4 later.

Last week we did an 'upgrade' from 9.30.HC4 to 9.30.HC5 and the applicati= on didn't start with the following error: /usr/lib/dld.sl: Unresolved symbol: idx_ggetenv (code) from /opt/informix= /lib/libifasf.sl = We found: From 9.30.HC4 to 9.30.HC5 the Connect Software has changed from 2.70 to 2= =2E80 !!!

Informix has always had this problem since going to shared libraries, that they occassionally reorganize the libraries (move functions from one lib to another) or eliminate functions. Usually this is involves one of the libraries that they do not have a version naming scheme for so you cannot have multiple versions in the same directory. Normally we do not recompile when installing new engine versions. But when this library glitch occurs then we either install the older iConnect after the engine or compile -static eliminating the problem at the expense of memory. Art S.
