- Type "make" to check the validity of the f2c source and compile f2c.
-
- If (in accordance with what follows) you need to modify the makefile
- or any of the source files, first issue a "make xsum.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 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 "index 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.
-
- Please send bug reports to dmg@research.att.com . The index file
- ("send index from f2c") will report recent changes in the recent-change
- log at its end; all changes will be shown in the "fixes" file
- ("send fixes from f2c"). To keep current source, you will need to
- request xsum0.out and version.c, in addition to the changed source
- files.
