C preprocessor in assembly

asi,

Can you provide the armasm line that your tool generates? Also, what version of armasm are you using.

I tried a line like this:

armasm --cpu=Cortex-R4 --cpreproc --cpreproc_opts=-DTHREAD_PROFILING_ENABLED -o .obj/xxx__xxx_restore.o ../../appsrc/xxx/xxx_restore.s

and it works as expected (no 1905 error)

hi emiller,

>>Can you provide the armasm line that your tool generates?

'Building file: ../xx_xxxxxx_xxxxx_restore.s'

'Invoking: ARM Assembler'

armasm --cpreproc --cpreproc_opts='-DTHREAD_PROFILING_ENABLED' --cpu=7-R --arm -g -o "xx_xxxxxx_xxxxx_restore.o" "../xx_xxxxxx_xxxxx_restore.s"

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

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

1 Error, 0 Warnings

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

**** Build Finished ****

>>Also, what version of armasm are you using.

ARM Assembler, 5.03 [Build 76]

>>and it works as expected (no 1905 error)

if there is some mistake please let me know,

ARM C/C++ Compiler, 5.03 [Build 76]

armcc OUTPUT:

'Building file: ../xx_xxxxxx_xxxxx_notify.c'

'Invoking: ARM C Compiler'

armcc -O3 --cpu=7-R --arm --apcs=/softfp -g -c -o "xx_xxxxxx_xxxxx_notify.o" "../xx_xxxxxx_xxxxx_notify.c"

'Finished building: ../xx_xxxxxx_xxxxx_notify.c'

Thanks.

Hi asi,

I'm not getting the same error as you.  I tried

ARM Assembler, 5.03 [Build 102]
and

ARM Assembler, 5.03 [Build 24]
(I don't have a copy of Build 76, so I can't duplicate your environment exactly).

I'll take a guess at a solution, but I can't guarantee it'll work: since assembly is failing with a C preprocessor error (the "C" in "C3472E" is for "Compiler, and the "E" is for "Error") saying that it can't decide between C90 and C++, you could specify which to use explicitly in your preprocessor options.

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.

Hi emiller,

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.

Hi Asi, would you mind closing the question and re-open it later if necessary? That helps keeping track of what requires attention.
