Makefile.in (install): Don't install if $(libsubdir) is empty...
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.
