From what I have been reading, the use of 'WITH_DEBUG' also prevents the stripping of debug code when the program is installed. Is that correct, or do I have to use another flag to insure that debug code is not stripped from the installed program? > Yes, it's true. There might be some weird ports, which do things in a non-standard way, this might not apply to those, but for the most of our ports, which respect the most important macros, it is going to work. -- Gabor Kovesdan FreeBSD Volunteer EMAIL: gabor@FreeBSD.org .:|:. gabor@kovesdan.org WEB: http://people.FreeBSD.org/~gabor .:|:. http://kovesdan.org
