g77 libU77
|
||
|
|
----------
|
||
|
|
|
||
|
|
This directory contains an implementation of most of the `traditional'
|
||
|
|
Unix libU77 routines, mostly an interface to libc and libm routines
|
||
|
|
and some extra ones for time and date etc. It's intended for use with
|
||
|
|
g77, to whose configuration procedure it's currently tied, but should
|
||
|
|
be compatible with f2c otherwise, if using the same f2c.h.
|
||
|
|
|
||
|
|
The contents of libU77 and its interfaces aren't consistent across
|
||
|
|
implementations. This one is mostly taken from documentation for (an
|
||
|
|
old version of) the Convex implementation and the v2 SunPro one.
|
||
|
|
As of g77 version 0.5.20, most of these routines have been made
|
||
|
|
into g77 intrinsics. Some routines have a version with a name prefixed
|
||
|
|
by `vxt', corresponding to the VMS Fortran versions, and these should
|
||
|
|
be integrated with g77's intrinsics visibility control.
|
||
|
|
|
||
|
|
A few routines are currently missing; in the case of `fork', for
|
||
|
|
instance, because they're probably not useful, and in the case of
|
||
|
|
`qsort' and those for stream-based i/o handling, because they need
|
||
|
|
more effort/research. The configuration should weed out those few
|
||
|
|
which correspond to facilities which may not be present on some Unix
|
||
|
|
systems, such as symbolic links. It's unclear whether the interfaces
|
||
|
|
to the native library random number routines should be retained, since
|
||
|
|
their implementation is likely to be something one should avoid
|
||
|
|
assiduously.
|
||
|
|
|
||
|
|
This library has been tested it under SunOS4.1.3 and Irix5.2 and there
|
||
|
|
has been some feedback from Linux; presumably potential problems lie
|
||
|
|
mainly with systems with impoverished native C library support which
|
||
|
|
haven't been properly taken care of with autoconf.
|
||
|
|
|
||
|
|
There's another GPL'd implementation of this stuff which I only found
|
||
|
|
out about recently (despite having looked) and I haven't yet checked
|
||
|
|
how they should be amalgamated.
