Sat Jun 13 03:46:40 1998 Craig Burley <burley@gnu.org> * Makefile.in (install): Don't install if $(libsubdir) is empty; issue a diagnostic saying top-level Makefile must pass it in instead, and exit. * Makefile.in (g2c.h): Rename from f2c.h. * Makefile.in, libF77/Makefile.in, libI77/Makefile.in, libU77/Makefile.in: Rewrite config and var assignment sections to be even more minimal than before, and to more clearly documented what macros are expected to be set and to what sorts of values. Eliminate CROSS and related stuff, since there's no such things as CROSS in egcs. Rename GCC_FOR_TARGET to CC throughout. * Makefile.in (stamp-libi77, stamp-libf77, stamp-libu77): Eliminate CROSS. * configure.in: Eliminate CROSS. Rename libf2c.a and f2c.h to libg2c.a and g2c.h, normalize and simplify g77/libg2c build process: * Makefile.in: Remove all stuff pertaining to installation, cleaning, and so on. Parent Makefile does all that now. Pass F2C_H_DIR, G2C_H_DIR, and GCC_H_DIR, the pathnames for the directories containing f2c.h, g2c.h, and other #include files, to subdirectory Makefiles. (stamp-libf77, stamp-libi77, stamp-libu77): Don't specify `-f Makefile' anymore, it's not needed now that subdirectory makefile's from netlib are renamed to makefile.netlib in g77 source (and to makefile.ori by configuration process, in case they're still around somehow). (stamp-libe77): Don't make libE77 dir unless it doesn't exist, if it does just delete all objects in it. Compile using $(GCC_FOR_TARGET), not $(CC). (rebuilt): Remove this and all subordinate targets, as parent Makefile now handles all that. (*clean): Remove. * configure.in (Pad_UDread, ALWAYS_FLUSH, WANT_LEAD_0): Remove these and commentary to new f2c.h file. AC_OUTPUT g2c.h instead of f2c.h. Remove old commentary regarding concatenation. * g2c.h.in: Rename from f2c.h.in, add appropriate commentary. * f2c.h: New file, a wrapper for g2c.h that does libg2c-specific stuff. * libF77/Makefile.in, libI77/Makefile.in, libU77/Makefile.in: Change $(ALL_CFLAGS) to use F2C_H_DIR, G2C_H_DIR, and GCC_H_DIR macros. Remove F2C_H macro, replace use with explicit dependencies on f2c.h and g2c.h. (*clean): Remove. From-SVN: r20507 |

19970811 -*-text-*- 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.
