Problems Compiling Certain Programs
Certain programs have problems compiling.
* Parse errors may occur compiling X11 on a Decstation running
Ultrix 4.2 because of problems in DEC's versions of the X11 header
files `X11/Xlib.h' and `X11/Xutil.h'. People recommend adding
`-I/usr/include/mit' to use the MIT versions of the header files,
using the `-traditional' switch to turn off ANSI C, or fixing the
header files by adding this:
#ifdef __STDC__
#define NeedFunctionPrototypes 0
#endif
* If you have trouble compiling Perl on a SunOS 4 system, it may be
because Perl specifies `-I/usr/ucbinclude'. This accesses the
unfixed header files. Perl specifies the options
-traditional -Dvolatile=__volatile__
-I/usr/include/sun -I/usr/ucbinclude
-fpcc-struct-return
most of which are unnecessary with GCC 2.4.5 and newer versions.
You can make a properly working Perl by setting `ccflags' to
`-fwritable-strings' (implied by the `-traditional' in the
original options) and `cppflags' to empty in `config.sh', then
typing `./doSH; make depend; make'.
* On various 386 Unix systems derived from System V, including SCO,
ISC, and ESIX, you may get error messages about running out of
virtual memory while compiling certain programs.
You can prevent this problem by linking GCC with the GNU malloc
(which thus replaces the malloc that comes with the system). GNU
malloc is available as a separate package, and also in the file
`src/gmalloc.c' in the GNU Emacs 19 distribution.
If you have installed GNU malloc as a separate library package,
use this option when you relink GCC:
MALLOC=/usr/local/lib/libgmalloc.a
Alternatively, if you have compiled `gmalloc.c' from Emacs 19, copy
the object file to `gmalloc.o' and use this option when you relink
GCC:
MALLOC=gmalloc.o
