106 | # The logic here is partly dictated by the desire to keep the lib?77 |

107 | # subdirs for compatibility with the Netlib version and because libU77 |

108 | # has a different copyright; then the libe77 bit (EXTERNALly-callable |
---|
109 | # versions) is funny. Given that, as well as keeping things as simple |
---|
110 | # as possible we want (at least) the following: |
---|
111 | # * Allow make to be run at the top level (all-target-libf2c), at this |
---|
112 | # level, or the subdirs of this level. In the latter case we only |
---|
113 | # compile, rather than updating libg2c.a; |
---|
114 | # * A robust set of dependencies, so that we rebuild (as little as |
---|
115 | # possible) if a configuration file, g2c.h or any lib?77/*.c file |
---|
116 | # changes; |
---|
