Hi eric,
     Thanks for your help. I use the header file to include the symbol But I still can't see it in semantic-lex-spp-describe(function name you gave is wrong^_^) output.
     I find it could work like this:
(semantic-c-add-preprocessor-symbol "__USE_POSIX" "1")
add this to .emacs then exit the emacs ,delete the db file. Restart , Ok.
     Thanks for your help again~

Hi,

 Preprocessor symbols from the flie are not placed into the the symbol map variable you listed.  Instead those two variables are combined.

You can use semantic-spp-lex-describe to list all the preprocessor symbols.

 Also, be sure to exit emacs, then delete ~/.semanticdb, then restart Emacs when doing a test.

firenet <kevinmiter@gmail.com> seems to think that:


My semantic-lex-c-preprocessor-symbol-file is
"/usr/include/c++/i486-linux-gnu/bits/c++config.h" . In that file no define
for __USE_POSIX so I add #define __USE_POSIX to the end
of this file. After deleting the .semanticdb dir, I found
semantic-lex-c-preprocessor-symbol-map don't have __USE_POSIX like before.
Where am I wrong? Thank you.ls

I looked in my signal.h on my ubuntu system, and the kill fcn is wrapped
like this:

#ifdef __USE_POSIX
extern int kill (__pid_t __pid, int __sig) __THROW;
#endif /* Use POSIX.  */

If I then do:

M-x semantic-spp-lex-describe

it does not list _USE_POSIX as an active macro.

You can use semantic-lex-c-preprocessor-symbol-map or
semantic-lex-c-preprocessor-symbol-file to add such #defines.  You would
then need to delete files from ~/.semanticdb that map to the system
includes with the problems.  That ought to fix this issue.
