How to strip binary in build?

Hi,

i release a new version of my app in the harbour store - and got the following comment:

The RPM validator issued the following warning for all 3 architetcures:

Libraries

WARNING [/usr/bin/harbour-saildsb] file is not stripped!
PASSED

The question now is, how do i strip the binary in the build?
What do i have to add to the spec file?

Thanks in advance,
Andreas

Have you left debug mode in the build by chance?
