All these symbols should be part of the postgres.imp file. Please recheck whether the file is proper and have these symbols.

Now, it seems any library or libraries are missing.

The error is because the .exp file is not having any symbols. Try the below steps.,
make clean
export OBJECT_MODE=64
make OPTFLAGS="-lm"

Maybe the following error is caused by postgres.imp or a problem in postgres packages?

Yes, looks like the import file is missed in the packaging. We will fix this.
For now, you can take the attached file here as postgres.imp

Hi,
I'm trying to build pgvector on AIX 7.2 and get following linkage error:
ld: 0706-003 Cannot find or read import file: /opt/freeware/lib64/postgresql/postgres.imp
ld:accessx(): No such file or directory
collect2: error: ld returned 255 exit status
# rpm -qa | grep postgres
postgresql15-libs-15.10-1.ppc
postgresql15-15.10-1.ppc
postgresql15-devel-15.10-1.ppc
postgresql15-server-15.10-1.ppc
Am I missing a package? Or, maybe is the postgres.imp missing in postgres15-devel package?
