Hello,

i am porting some legacy code that hash a nice logging macro

that uses varargs to tag the line, file of the message.

I have tried both the old gcc syntax and the new iso

but i could not get it to work.

Is code like this supposed to work?

#define dlog(fmt, ...) log(__LINE__, __FILE__, fmt, __VA_ARGS__)

I did look for the manual of the compiler (to know the language,

preprocessor and command line switches) but i did not

find any.

Thank You ..

I'm not familiar with what you are doing specifically but depending on the target you're looking for a CGT guide:

If you are building for an ARM I think they just use GCC, so any GCC documentation should apply (note: I'm not an ARM/Linux expert but this is my understanding [:)])

The latest versions of TI compilers do support variable arguments in macros when --gcc option is enabled. This option is documented in the Compiler Users Guides for the different device families.

Hello,

i am targeting a TMS320C6415 with some code that is running

with gcc (arm), visualdsp++ (blackfin) and x86 with visual studio.

the code is c++ (very simple classes, no rtti or templates)

so the --gcc extension parameter don't work.

the macro add the filename and a line number to every

log message that is "printed" by the library.

the link is usefull, will read. thanks.

thank you for your reply,

unfortunately my code is c++ and the -gcc option seem to be unsupported with c++.
