#ident query

#ident query

[Barry Clarkson]

Hi,

I'm in the process of porting some code to a Linux
based platform that is using gcc 3.2.2.  I am trying
to enforce ansi C (as near as possible!) but there are
#ident directives within the code for third party
source control. What can I modify within the source
(not ideal) or on the command line to get ansi C and
safely ignore the '#ident' directives (tried
-fno-ident)?

Thanks in advance,

Barry

GCC version...

Simple.

Hi Barry,

You could pre-process the source file to remove the offending #ident lines 
before compiling.

This will remove the line entirely...

grep -v -e '^#ident' source.c >source.c1
gcc -pedantic -W -Wall -o source.o -x c source.c1

Or this will replace the line with a blank line...

sed -e 's/^#ident.*$//' source.c >source.c1
gcc -pedantic -W -Wall -o source.o -x c source.c1

HTH,

The only way to modify the command line would be to remove
-pedantic-errors.  If you use -pedantic-errors, you are asking to
compiler to give you an error for anything which is pedantically
incorrect.  #ident is pedantically incorrect.  There is no option for
"all pedantic errors except this particular one."

If you insist on -pedantic-errors, then you need to modify the source
code to remove the #ident directives.
