Compiling/Linking COBOL code on a RHEL 8.6, which compiles fine but then when it tries to link I get an error with one of the variables: cob2 -F//etc/cob2.cfg -v <cobolprog.cbl> -L/lib64 -ldb2 -I/include/cobol_a/ -q"size(16384K) -o cobolprog
The output is /usr/bin/ld: skipping incompatible lib64/libdb2.so when searching for -ldb2 /usr/bin/ld: cannot find -ldb2 If I remove the -ldb2 I get 'undefined reference to 'SQLGSTRT', 'SQLGALOC etc
When I try this with lib32 and -ldb2 I dont see issues?
I did try using the -q64 on the cmd line but apparently this is not supported on linux.

Tried 32 bit which compiles the cobol fine, but it now seems to have an issue with linking a static library I need: /usr/bin/ld: /usr/lib/gcc/x86_64-redhat-linux/8/../../../../lib/Scrtl.0(.text+0x1c): unresolvable R_386_GOTOFF relocation against symbol '__libc_csu_fini'
It appears that you are using IBM COBOL for Linux on x86 version 1.1.
According to IBM's documentation at this link the ADDR compiler option specifies whether to create a 32-bit or 64-bit object file.
Additionally, as you are on version 1.1 (the currently available version as of February-2023), the documentation also has this specific relevant note:
Note: The ADDR(64) and -q64 options are not currently supported. The compiler accepts and ignores these options and defaults to ADDR(32).
This means that your object file is 32-bit, but you are trying to link (ld) with the 64-bit Db2 libraries, and consequently ld skips the incomptabile library with the message that you see. You should Link with the 32-bit Db2 libraries instead, they are in the lib32 directory of the Db2 client, so arrange for this in your command line options.
