| # The logic here is partly dictated by the desire to keep the lib?77 |
| # subdirs for compatibility with the Netlib version and because libU77 |
| # has a different copyright; then the libe77 bit (EXTERNALly-callable |
| # versions) is funny. Given that, as well as keeping things as simple |
| # as possible we want (at least) the following: |
| # * Allow make to be run at the top level (all-target-libf2c), at this |
| # level, or the subdirs of this level. In the latter case we only |
| # compile, rather than updating libg2c.a; |
| # * A robust set of dependencies, so that we rebuild (as little as |
| # possible) if a configuration file, g2c.h or any lib?77/*.c file |
| # changes; |
| # * Avoid unnecessary running of ar and ranlib; |
| # * Expose parallelism where reasonable, but not as a priority. |
| |
| # The intended top-level target here does a non-multilib build (via |
| # the dependency) and then (perhaps) builds multilibs. |

| # update stamp files (see the subdir makefiles) which the $(LIBG2C) |
| # target checks in the sub make to decide whether to run ar/ranlib. |
| # (Probably only one stamp file is really needed.) The stamp files |
| # s-lib[fiu]77 are intentionally not targets, since we're only meant |
| # to come in at the level of this target. The [fiu]77 targets always |
| # invoke sub makes to check dependencies in the subdirs, else we'd |
| # have to maintain them at this level; we live with the overhead of |
