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. From-SVN: r20507
