C preprocessor in assembly

Asif Rizwan

IDE:           ARM DS-5 (v5.15.0)

Platform:    Cortex R4

Hi,

I am interested to use C pre-processor in assembly file but i am facing the attached issue. According to arm documentation

Using the C preprocessorFlag.png

I set the flag --cpreproc and --cpreproc_opts but getting following issue:


Error: C3472E: No source language specified (--cpp or --c90) and sourcefile extensions conflict

Fatal error: A1905U: Pre-processor step failed for '../xx_xxxxxx_xxxxx_restore.s'

1 Error, 0 Warnings

make: *** [xx_xxxxxx_xxxxx_restore.o] Error 8

I really appreciate your suggestions.

Thanks.

    Hi emiller,

    >>So instead of "--cpreproc_opts='-DTHREAD_PROFILING_ENABLED'," try "--cpreproc_opts='--c90 -DTHREAD_PROFILING_ENABLED'," which I would expect to get you past the 3472 error.

    Sorry for late response, I tried that one earlier but didn't succeed. I will try it again with [Build 102] and hit back there with results.

    Thanks.
