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 DECs 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 the following
input.
#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 following options
most of which are unnecessary with GCC 2.4.5 and newer versions.
-traditional -Dvolatile=__volatile__
-I/usr/include/sun -I/usr/ucbinclude
-fpcc-struct-return
You can make a properly working
Perl by setting ccflags
to -fwritable-strings
(implied by the option, -traditional,
in the original options) and cppflags
to empty in config.sh,
then using the following input.
./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 GNU CC 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 the following option when you relink
GNU CC.
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 the following option when you relink GNU CC.
MALLOC=gmalloc.o
