I've said it before, and I guess I'll end up saying it again in the future, and I'm going to repeat myself now just for good measure: The only way to link anything that uses ESQL/C is to use the esql script to do the linking. The libraries used by Informix change with every release, for most purposes. You should certainly assume that they do. The job of the esql script is to keep on top of the changes. If you really decide to do the linking manually, you will have to be prepared to redesign your link lines for each release of ESQL/C, on each platform where you port your software. If you use the esql script, you don't! Note the per-platform bit; there is no guarantee that the libraries used on a Solaris machine are the same as the ones used on an HP-UX or DEC OSF/1 machine. Be aware that the 9.12 release (IUS and DevSDK - Developer's SDK, previously called ESQL/C) have yet more libraries and the names have been changed systematically, and so on, in comparison with both earlier 9.0x and 9.1x releases, and in comparison with 7.2x releases, etc. But, I have ESQL/C programs which compile and link OK under 5.00 through 9.12 using the esql script on a number of platforms -- that really is the only way to do it!

The compilation scripts are designed to protect innocent users (eg you) from the harsh realities of what is necessary to get the products to work. Use the esql script for compiling and linking. The list of libraries varies from version to version. And if you get to ESQL/C version 7.20, you get threaded libraries and non-threaded libraries in shared and non-shared forms, etc. Also, there are places where the order of the libraries changes depending on whether the libraries are threaded or not. The list of libraries required changes too. Do not, ever, try doing without the esql script. Use it; do not try to avoid using it, because you will be bitten, probably badly, when you port to a different machine, or a new version of the products. Similar comments apply to I4GL and the c4gl script. If you want to switch compilers, you can set the INFORMIXC environment variable.

Build library: ar ru libmine.a libfile1.o libfile2.o libfile3.o Link with library: esql -o myprog myesql1.o myesql2.o -L. -lmine or: esql -o myprog myesql1.o myesql2.o libmine.a Substitute the directory where the library is for the dot in the "-L." option. Unrecognized options are passed through ESQL to the C compiler. That means you can play games with "-Wall -Wshadow -ansi -pedantic" and the GCC compiler, and use the esql script, etc. Yours, Jonathan Leffler (johnl@informix.com) #include <disclaimer.h> PS: I think the c.d.i newsgroup might benefit from this answer -- please post it if you agree.

I haven't had to fix Purify; I simply arrange that the environment variable INFORMIXC is set to "purify cc" and it all works fine. That, of course, assumes that you have a sufficiently recent esql script that it recognizes this environment variable, but I'd rather fix the esql script than the purify script.
