If your system lacks /usr/include/local.h ,
|
||
|
|
then you should create an appropriate local.h in
|
||
|
|
this directory. An appropriate local.h may simply
|
||
|
|
be empty, or it may #define VAX or #define CRAY
|
||
|
|
(or whatever else you must do to make fp.h work right).
|
||
|
|
Alternatively, edit fp.h to suite your machine.
|
||
|
|
|
||
|
|
If your system lacks /usr/include/fcntl.h , then you
|
||
|
|
should simply create an empty fcntl.h in this directory.
|
||
|
|
|
||
|
|
If your system's sprintf does not work the way ANSI C
|
||
|
|
specifies -- specifically, if it does not return the
|
||
|
|
number of characters transmitted -- then insert the line
|
||
|
|
|
||
|
|
#define USE_STRLEN
|
||
|
|
|
||
|
|
at the end of fmt.h . This is necessary with
|
||
|
|
at least some versions of Sun software.
|
||
|
|
|
||
|
|
If your system's fopen does not like the ANSI binary
|
||
|
|
reading and writing modes "rb" and "wb", then you should
|
||
|
|
compile open.c with NON_ANSI_RW_MODES #defined.
|
||
|
|
|
||
|
|
If you get error messages about references to cf->_ptr
|
||
|
|
and cf->_base when compiling wrtfmt.c and wsfe.c or to
|
||
|
|
stderr->_flag when compiling err.c, then insert the line
|
||
|
|
|
||
|
|
#define NON_UNIX_STDIO
|
||
|
|
|
||
|
|
at the beginning of fio.h, and recompile these modules.
|
||
|
|
|
||
|
|
You may need to supply the following non-ANSI routines:
|
||
|
|
|
||
|
|
fstat(int fileds, struct stat *buf) is similar
|
||
|
|
to stat(char *name, struct stat *buf), except that
|
||
|
|
the first argument, fileds, is the file descriptor
|
||
|
|
returned by open rather than the name of the file.
|
||
|
|
fstat is used in the system-dependent routine
|
||
|
|
canseek (in the libI77 source file err.c), which
|
||
|
|
is supposed to return 1 if it's possible to issue
|
||
|
|
seeks on the file in question, 0 if it's not; you may
|
||
|
|
need to suitably modify err.c . On non-UNIX systems,
|
||
|
|
you can avoid references to fstat and stat by compiling
|
||
|
|
err.c, inquire.c, open.c, and util.c with MSDOS defined;
|
||
|
|
in that case, you may need to supply access(char *Name,0),
|
||
|
|
which is supposed to return 0 if file Name exists,
|
||
|
|
nonzero otherwise.
|
||
|
|
|
||
|
|
char * mktemp(char *buf) is supposed to replace the
|
||
|
|
6 trailing X's in buf with a unique number and then
|
||
|
|
return buf. The idea is to get a unique name for
|
||
|
|
a temporary file.
|
||
|
|
|
||
|
|
On non-UNIX systems, you may need to change a few other,
|
||
|
|
e.g.: the form of name computed by mktemp() in endfile.c and
|
||
|
|
open.c; the use of the open(), close(), and creat() system
|
||
|
|
calls in endfile.c, err.c, open.c; and the modes in calls on
|
||
|
|
fopen() and fdopen() (and perhaps the use of fdopen() itself
|
||
|
|
-- it's supposed to return a FILE* corresponding to a given
|
||
|
|
an integer file descriptor) in err.c and open.c (component ufmt
|
||
|
|
of struct unit is 1 for formatted I/O -- text mode on some systems
|
||
|
|
-- and 0 for unformatted I/O -- binary mode on some systems).
|
||
|
|
|
||
|
|
For Turbo C++, in particular, you need to adjust the mktemp
|
||
|
|
invocations and should compile all of libI77 with -DMSDOS .
|
||
|
|
You also need to #undef ungetc in lread.c and rsne.c .
|
||
|
|
Don't use -mh -- it is horribly broken.
|
||
|
|
|
||
|
|
If you want to be able to load against libI77 but not libF77,
|
||
|
|
then you will need to add sig_die.o (from libF77) to libI77.
|
||
|
|
|
||
|
|
If you wish to use translated Fortran that has funny notions
|
||
|
|
of record length for direct unformatted I/O (i.e., that assumes
|
||
|
|
RECL= values in OPEN statements are not bytes but rather counts
|
||
|
|
of some other units -- e.g., 4-character words for VMS), then you
|
||
|
|
should insert an appropriate #define for url_Adjust at the
|
||
|
|
beginning of open.c . For VMS Fortran, for example,
|
||
|
|
#define url_Adjust(x) x *= 4
|
||
|
|
would suffice.
|
||
|
|
|
||
|
|
To check for transmission errors, issue the command
|
||
|
|
make check
|
||
|
|
This assumes you have the xsum program whose source, xsum.c,
|
||
|
|
is distributed as part of "all from f2c/src". If you do not
|
||
|
|
have xsum, you can obtain xsum.c by sending the following E-mail
|
||
|
|
message to netlib@research.att.com
|
||
|
|
send xsum.c from f2c/src
|
||
|
|
|
||
|
|
The makefile assumes you have installed f2c.h in a standard
|
||
|
|
place (and does not cause recompilation when f2c.h is changed);
|
||
|
|
f2c.h comes with "all from f2c" (the source for f2c) and is
|
||
|
|
available separately ("f2c.h from f2c").
