informix 15 esql in conjunction with latest AIX compiler generation
Peter Weigert reported that the esql script in Informix 15 hardcodes xlclang and -q options, which the AIX XL C/C++ V17 compilers (ibm-clang) do not accept, forcing him to edit the script. David Williams advised opening a support case or moving to gcc. Sebastien Flaesch asked for a ticket number or new CSDK 15 release. No official fix was reported.

Dear community! In the Machine Notes for my Installation is noted that: 1. This product was built on AIX 7.2 Technology using the following compilers: IBM XL C/C++ for AIX, V16.1.0 (5725-C72, 5765-J12) XL C/C++ Runtime 16.1.0.10 That is quite ok for me, but when it comes to the point to use the esql command I am failing on the specific issue that we need to proceed to the V17 compiler generation which is installed on the machine. esql assumes, the compiler to be named xlclang by default. This can be overridden by defining $INFORMIXC in the environment. But still I need to modify the installed esql-script, as they imply fixed compiler flags: CC="${INFORMIXC=xlclang} -qchars=signed -m64 -qcheck=nullptr -qmaxmem=-1 -qspill=2000" In the V17 compiler generation the compiler is named by one of these entry-names: -rwxr-xr-x 1 root system 442 Oct 18 2023 ibm-clang -rwxr-xr-x 1 root system 488 Oct 18 2023 ibm-clang++_r -rwxr-xr-x 1 root system 460 Oct 18 2023 ibm-clang-cpp -rwxr-xr-x 1 root system 468 Oct 18 2023 ibm-clang_r But none of these is supporting the legacy options named by -q. We may modify this to "-fsigned-char -m64 -fsanitize=nullability" (hopefully it's really the same) but for the spillsize i did not find a viable equivalent. On the other hand the 13.1.3 compiler can't manage the -m64 option which requires to be modifed to -q64 I do not want to change the esql command, but I see no other options for now. Does anyone have a suggestion? krgds Peter ------------------------------ Peter Weigert ------------------------------
Hi, I would open a support case. Regards, David. ------------------------------ David Williams Senior Database Platform Engineer Flutter London ------------------------------
Hello! Has this issue been registered as support case? If yes, can someone provide the ticket id? Is there a new Informix CSDK 15 version available? Thanks! Seb ------------------------------ Sebastien FLAESCH ------------------------------
Hi, Go back to the AIX compiler people at tell them to not break people's compile scripts! If they want to change the name of the compiler binary and flags then they should make that a new product and not break compatability in v17. I would move to gcc, it is free and I have not had compatability issues with it!

Hi David, I understand your frustration. I did not look in detail to this problem, but as far as we are concerned, we plan to port our product on AIX 7.3, potentially with IBM V17 compiler, so I need a solution. If this issue is filed somewhere at IBM or HCL issue database, I would appreciate to get a ticket number/id, and we'll watch for a fix / new CSDK release. Otherwise, short term, if patching the esql script is the solution, we'll do that. Seb ------------------------------ Sebastien FLAESCH ------------------------------
