Revision 1.2, Tue Feb 8 04:47:09 2000 UTC (24 years, 7 months ago) by noro
Branch: MAIN
Changes since 1.1: +4 -1
lines
Cleaned up source files for creating libasir*.a with various
configurations.
Added new targets in src/asir2000/Makefile
install-lib-with-pari : libasir_pari.a -> OpenXM/lib
install-lib-small : libasir.a -> OpenXM/lib
install : asir libasir_pari_X.a libasir_gc.a -> OpenXM/lib
libasir_pari_X.a requires libpari.a and X11 libraries.
libasir_pari.a requires libpari.a.
libasir.a requires nothing.
