All these paths are relative and would be relative to the variantdir
specified in the parent..
so
build/fwk/systemServices/stupd/fwk/simulation_fwk/core/logger_c/logger_c.sc
And the variant dir would be:
build/fwk/systemServices/stupd/build/fwk/systemServices/stupd/

Likely you really want:
libraries = SConscript('#fwk/simulation_fwk/core/logger_c/logger_c.sc',
exports='envService', variant_dir='#build/fwk/systemServices/stupd/',
duplicate=0)

?
