Type "make" to check the validity of the f2c source and compile f2c.
|
|
|
|
On a PC, you may need to compile xsum.c with -DMSDOS (i.e., with
|
|
MSDOS #defined). If your system does not understand ANSI/ISO C
|
|
syntax (i.e., if you have a K&R C compiler), compile xsum.c with
|
|
-DKR_headers. (Eventually this will also be required of the f2c
|
|
source proper.)
|
|
|
|
On non-Unix systems where files have separate binary and text modes,
|
|
you may need to "make xsumr.out" rather than "make xsum.out".
|
|
|
|
If (in accordance with what follows) you need to modify the makefile
|
|
or any of the source files, first issue a "make xsum.out" (or, if
|
|
appropriate, "make xsumr.out") to check the validity of the f2c source,
|
|
then make your changes, then type "make f2c".
|
|
|
|
The file usignal.h is for the benefit of strictly ANSI include files
|
|
on a UNIX system -- the ANSI signal.h does not define SIGHUP or SIGQUIT.
|
|
You may need to modify usignal.h if you are not running f2c on a UNIX
|
|
system.
|
|
|
|
Should you get the message "xsum0.out xsum1.out differ", see what lines
|
|
are different (`diff xsum0.out xsum1.out`) and ask netlib to send you
|
|
the files in question "from f2c/src". For example, if exec.c and
|
|
expr.c have incorrect check sums, you would send netlib the message
|
|
send exec.c expr.c from f2c/src
|
|
|
|
On some systems, the malloc and free in malloc.c let f2c run faster
|
|
than do the standard malloc and free. Other systems cannot tolerate
|
|
redefinition of malloc and free. If yours is such a system, you may
|
|
either modify the makefile appropriately, or simply execute
|
|
cc -c -DCRAY malloc.c
|
|
before typing "make". Still other systems have a -lmalloc that
|
|
provides performance competitive with that from malloc.c; you may
|
|
wish to compare the two on your system.
|
|
|
|
On some BSD systems, you may need to create a file named "string.h"
|
|
whose single line is
|
|
#include <strings.h>
|
|
you may need to add " -Dstrchr=index" to the "CFLAGS =" assignment
|
|
in the makefile, and you may need to add " memset.o" to the "OBJECTS ="
|
|
assignment in the makefile -- see the comments in memset.c .
|
|
|
|
For non-UNIX systems, you may need to change some things in sysdep.c,
|
|
such as the choice of intermediate file names.
|
|
|
|
On some systems, you may need to modify parts of sysdep.h (which is
|
|
included by defs.h). In particular, for Sun 4.1 systems and perhaps
|
|
some others, you need to comment out the typedef of size_t. For some
|
|
systems (e.g., IRIX 4.0.1 and AIX) it is better to add
|
|
#define ANSI_Libraries
|
|
to the beginning of sysdep.h (or to supply -DANSI_Libraries in the
|
|
makefile).
|
|
|
|
Alas, some systems #define __STDC__ but do not provide a true standard
|
|
(ANSI or ISO) C environment, e.g. do not provide stdlib.h . If yours
|
|
is such a system, then (a) you should complain loudly to your vendor
|
|
about __STDC__ being erroneously defined, and (b) you should insert
|
|
#undef __STDC__
|
|
at the beginning of sysdep.h . You may need to make other adjustments.
|
|
|
|
For some non-ANSI versions of stdio, you must change the values given
|
|
to binread and binwrite in sysdep.c from "rb" and "wb" to "r" and "w".
|
|
You may need to make this change if you run f2c and get an error
|
|
message of the form
|
|
Compiler error ... cannot open intermediate file ...
|
|
|
|
On many systems, it is best to combine libF77 and libI77 into a single
|
|
library, say libf2c, as suggested in "readme from f2c". If you do this,
|
|
then you should adjust the definition of link_msg in sysdep.c
|
|
appropriately (e.g., replacing "-lF77 -lI77" by "-lf2c").
|
|
|
|
Some older C compilers object to
|
|
typedef void (*foo)();
|
|
or to
|
|
typedef void zap;
|
|
zap (*foo)();
|
|
If yours is such a compiler, change the definition of VOID in
|
|
f2c.h from void to int.
|
|
|
|
For convenience with systems that use control-Z to denote end-of-file,
|
|
f2c treats control-Z characters (ASCII 26, '\x1a') that appear at the
|
|
beginning of a line as an end-of-file indicator. You can disable this
|
|
test by compiling lex.c with NO_EOF_CHAR_CHECK #defined, or can
|
|
change control-Z to some other character by #defining EOF_CHAR to
|
|
be the desired value.
|

|
Please send bug reports to dmg@research.att.com . The old index file
|
|
(now called "readme" due to unfortunate changes in netlib conventions:
|
|
"send readme from f2c") will report recent changes in the recent-change
|
|
log at its end; all changes will be shown in the "changes" file
|
|
("send changes from f2c"). To keep current source, you will need to
|
|
request xsum0.out and version.c, in addition to the changed source
|
|
files.
