How to find out what options a library was configured with when it was installed
 

Hello
Is there a way to find out with what options a library was configured with when it was installed?

I am trying to install a library on my system that depends on gasnet and it requires me to configure it with the very same options that gasnet was configured with. Gasnet was not originally installed by me, so I cannot tell. I can see bin/, include/, lib/ and share/ directories in the gasnet folder and no other information in it. To be specific, I need to use the same CFLAGS that were used during installation of gasnet. For example, if it was installed using '-g -O2', I have to make sure I use the same CFLAGS here.

Your help is appreciated.

I do not think it is possible to determine this information from the library itself. The packaging system may be able to help. Which distribution are you using?

Its a remote machine, and looks like its running Redhat.

If it was installed using the package system, then the following rpm command could help.

rpm -q --queryformat="%{NAME}: %{OPTFLAGS}\n" gasnet

Looks like gasnet was not installed as an rpm package, it might have been installed manually using the standard 'configure,make,make install' process.

'rpm -q --queryformat="%{NAME}: %{OPTFLAGS}\n" gasnet' says that gasnet was not installed and i dont see it either using
'rpm -qa | grep -i gasnet'

Thanks for your help though.
