Subject: problems with lclint, gcc, unixware
Content-Type: text/plain; charset=us-ascii
I've had a couple problems with lclint 2.0 under unixware 1.12 with
gcc 2.6.3. I've
come up with work-arounds, so this is more of a is there a better
1. lclint seems to look in /usr/include for its headers files.
Since gcc supplies its own system header files elsewhere, this
leads to parsing errors and other troubles. I frankly don't
understand why lclint doesn't use gcc to do its preprocessing, but
I dutifully set BASEPATH and DEFAULT_SYSTEMDIR in constants.h and
SYSTEM_LIBDIR in Makefile to the location of gcc's header files.
This seems to cure the problem, but it will require the update of a symlink
for every new release of gcc we install (small maintenance headache).
My questions are,
why doesn't lclint use gcc to do the preprocessing and was this
the "right" way to handle this problem?
2. lclint barfs (unrecoverable parse error) on gcc's __asm__ statement.
Unfortunately, this is used in an inline function in one of
gcc's header files (sys/byteorder.h). I'm loath to
change gcc's header files because of the maintenance headache,
so we managed to keep that file from being included for now.
Is there a way to get lclint to understand __asm__? If not,
I hereby request this feature for the next release. :-)
