Compile GiNaC 1.2.0 on cygwin using gcc 3.2 20020927: ginac/remember.cpp table_size = 1 << log2(s); The compiler doesn't like the mixture of integer and double on operator<<. I used int(log2(s)). If this is also the place to report CLN build issues, version 1.1.5 */Makefile.in do not include LDFLAGS = @LDFLAGS@ so it couldn't find my version of libgmp.a. Paul Kienzle pkienzle@nist.gov
