I have just installed ginac-0.6.2 on a PC under NT4SP5 using gcc-2.95/cygwin (http://sourceware.cygnus.com/cygwin). There were two minor problems fixed by patches below. 1. cygwin defines a macro log2, which confuses ginac function in utils 2. a builddir != srcdir cannot find ginsh/*.sed files After these fixes the build and the checks were OK. +++++++++++++++++++++++++++++++++++++++++ (Mr) David Billinghurst Comalco Research Centre PO Box 316, Thomastown, Vic, Australia, 3074 Phone: +61 3 9469 0642 FAX: +61 3 9462 2700 Email: David.Billinghurst@riotinto.com.au --- ginsh/Makefile.am.orig Sat Feb 5 02:03:58 2000 +++ ginsh/Makefile.am Thu Jun 29 09:53:56 2000 @@ -10,10 +10,10 @@ EXTRA_DIST = $(man_MANS) ginsh_parser.h ginsh_fcn_help.sed ginsh_op_help.sed # files created by sed scripts -ginsh_fcn_help.c: ginsh.1 ginsh_fcn_help.sed - sed -n -f ginsh_fcn_help.sed <$< >$@ +ginsh_fcn_help.c: ginsh.1 $(srcdir)/ginsh_fcn_help.sed + sed -n -f $(srcdir)/ginsh_fcn_help.sed <$< >$@ -ginsh_op_help.c: ginsh.1 ginsh_op_help.sed - sed -n -f ginsh_op_help.sed <$< >$@ +ginsh_op_help.c: ginsh.1 $(srcdir)/ginsh_op_help.sed + sed -n -f $(srcdir)/ginsh_op_help.sed <$< >$@ ginsh_parser.o: ginsh_fcn_help.c ginsh_op_help.c --- ginac/utils.h.orig Tue Jun 27 23:20:32 2000 +++ ginac/utils.h Wed Jun 28 21:12:29 2000 @@ -45,6 +45,7 @@ * signal that ordinary Taylor expansion is safe. */ class do_taylor {}; +#undef log2 unsigned log2 (unsigned n); int compare_pointers(const void * a, const void * b);
