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?

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

The error is because the .exp file is not having any symbols. Try the below steps.,

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

Hi,

ld: 0706-003 Cannot find or read import file: /opt/freeware/lib64/postgresql/postgres.imp

Am I missing a package? Or, maybe is the postgres.imp missing in postgres15-devel package?

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.
