I am also getting the above error any resolution for this

Hi, I am also having issues in compiling pdo_informix.

I am using the below:
CentOS 7.8 (clean install)
php 5.4 (from yum)
informix CSDK clientsdk.3.70.FC8DE
PDO_INFORMIX-1.3.1

I can complile the pdo_informix with no issue, but when I do the make test, I am getting the below error. (Especially undefined symbol: pdo_parse_params). Would anyone have any idea how to solve this? Thanks

make test

Build complete.
Don't forget to run 'make test'.

update (1)
Looks like "make test" failed. But I still install it by "make install" and then I do the test and it works. Thanks a lot for all your help. I would like to share the process I used to make it work if someone would find it useful.
