The easiest way to build a new client (X application) is to use
xmkmf if an Imakefile is included in the sources. Type
``xmkmf -a'' to create the Makefiles, check the configuration if
necessary and type ``make''. Whenever you install additional man
pages you should update whatis.db by running ``makewhatis
/usr/X11R6/man''.
When porting clients to *BSD systems, make use of the symbol BSD for code which is truly BSD-specific. The value of the symbol can be used to distinguish different BSD releases. For example, code specific to the Net-2 and later releases can use:
#if (BSD >= 199103)
To ensure that this symbol is correctly defined, include
<sys/param.h> in the source that requires it. Note that
the symbol CSRG_BASED is defined for *BSD systems in XFree86 3.1.1
and later. This should be used to protect the inclusion of
<sys/param.h>.
For code that really is specific to a particular i386 BSD port, use __FreeBSD__ for FreeBSD, __NetBSD__ for NetBSD, __OpenBSD__ for OpenBSD, and __bsdi__ for BSD/386.
