IBM Data and AI Ideas Portal for Customers
Shape the future of IBM!
We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:
Post your ideas
Post ideas and requests to enhance a product or service. Take a look at ideas others have posted and upvote them if they matter to you,
Post an idea
Upvote ideas that matter most to you
Get feedback from the IBM team to refine your idea
Help IBM prioritize your ideas and requests
The IBM team may need your help to refine the ideas so they may ask for more information or feedback. The product management team will then decide if they can begin working on your idea. If they can start during the next development cycle, they will put the idea on the priority list. Each team at IBM works on a different schedule, where some ideas can be implemented right away, others may be placed on a different schedule.
Receive notification on the decision
Some ideas can be implemented at IBM, while others may not fit within the development plans for the product. In either case, the team will let you know as soon as possible. In some cases, we may be able to find alternatives for ideas which cannot be implemented in a reasonable time.

OK, I've found a workaround. Add '--static' to the STATICFLAGS variable at the top of the esql script in $INFORMIXDIR/bin and it will compile with gcc versions after v7. Note that you will get a warning about the executable still requiring certain system shared libraries of the same (or compatible?) GCC release, but it will create a working fully static executable! Still, this needs work.
Dectoint.ec is just too simple to pull in the problematic libs. Yes, I can link that one also, but try something more complex and BOOM! Witness:
informix@Elbereth:/opt/informix/infmx/demo/esqlc$ esql -static dectoint.ec -o dect
