I checked in my development LPAR’s on AIX 7.2 node and there also we do not need to calculate rpath.

Also liked your suggestion to use disable rpath which also is all right for us.

Just that if someone runs test cases without disabling rpath then the test cases won’t run.(Only while using the GNU build system in AIX)

For which I have one suggestion,
# -blibpath must contain ALL directories where we should look for libraries
libpath := $(shell echo $(subst -L,:,$(filter -L/%,$(LDFLAGS))) | sed -e's/ //g'):/opt/freeware/lib:/usr/lib:/lib

How about adding "/opt/freeware/lib” to the calculation like the above lines. This is the standard path where all AIX open-source freeware libraries will exist, and system libraries will be in /usr/lib. We have this differentiation in AIX.

This will allow the test cases to find the open-source libraries incase rpath is calculated and both of our requirements are satisfied.

Let me know if we can do that.

Have a nice day ahead.

Thanks and regards,
Aditya.
