Admonition understood - I was just experimenting and wanted the file to be in a specific place without any uncertainty about just what various "look over there" options actually do. The reason for such a mind set is that actual behavior of cpp seems to differ from its documentation, to wit: info cpp :: Header Files::Search Path reads: GCC looks in several different places for headers. On a normal Unix system, if you do not instruct it otherwise, it will look for headers requested with `#include ' in: /usr/local/include LIBDIR/gcc/TARGET/VERSION/include /usr/TARGET/include /usr/include I'm either missing something very fundamental (which I doubt not at all) or this should be a somewhat serious problem. There are 4944 header files in /usr/local/include/ branch on this system that should be accessible by default but, if my experience with nzbget is any guide, do not seem to be. -- Walter M.

Even though cc has a million options, there's none that I know that prints the system include path (not even in -dumpspecs). However, in practice you can assume it's /usr/include. To make configure scripts believe you have something installed, it's not a good idea to copy headers. Look for a --with-iconv=/usr/local option and failing that, change CFLAGS and LDFLAGS in the environment when configuring. -- Mel Problem with today's modular software: they start with the modules and never get to the software part. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
What is CPP's real default include path?
I've been fiddling with compiling nzbget-0.4.0 on a 6.3 system. My initial efforts failed the configuration process for not finding iconv.h. This, despite /usr/local/include/iconv.h being present and supposedly in the include search path if the info documentation can be believed. Just to see if I could learn something, I copied the /usr/local/include/iconv.h to /usr/include/ and tried again. After this, the configuration process completed and the application seemed to "make" and "make install" just fine. Is there some way to ascertain what the set of default include paths actually is? -- Walter M.
