Build & Run Customization

[nettrino]

Hello all, sorry if this is somewhere in the documentation and I have missed it, but is there some option to customize
the build & run options for a particular benchmark? In particular, suppose I want to run the apache benchmark but
I want to build it with some extra flags in gcc and run apache binary doing a LD_PRELOAD of a module of mine. Is that
possible without modifying source code directly?

Thanks a lot

Generally speaking, the CFLAGS/CXXFLAGS are honored by the test profile and other build arguments as long as they are honored by the upstream program you're planning to test. Likewise, LD_PRELOAD is honored too. PTS generally doesn't force override any of these important flags.

Thank you very much from the prompt the reply! I did not have a clear view of the test-profile concept. It makes sense now.
I copied the apache profile from .phoronix-test-suite/test-profiles/pts into local and made the changes there, but when I try
to run my test (which is successfully listed in list-available-tests), I get the error

The test executable for local/apache-XXX could not be located

.
From what I see it is compiled. Any ideas what am I doing wrong or what part of the documentation I am missing?

Thank you again

Btw I tried to modify the profile parameters directly inside pts/apache-1.6.1 and works as expected but ideally I would like to keep different local configurations
to perform a series of tests.

Is the name of the test script being run called apache?

Got it! Thank you again for the support (and great work!)

Cheers, by the way, if it's an interesting test the test is happily accepted upstream.
