Recently I was interested in migrating the GiNaC from Unix to Windows,
FYI, GiNaC compiles and works just fine (as a static library) on win32.
but I only need the symbolic operation not the large number operation,
If you need symbolic operations you need bignum operations too.
so I was wondering whether I can get rid of the CLN lib from the GiNaC,
Yes, to some extent. You can replace it with another bignum library, such as GMP.
can any one tell me that where and how the GiNaC uses the CLN?
1. ginac/expairseq.{h,cpp}. Numeric coefficients in sums and products are cln::cl_N. 2. ginac/normal.cpp gcd(), normal() need bignums. 3. numeric evaluation (evalf())
Is it practicable that exclude the CLN lib?
I don't think so. You'd better put the effort somewhere else. Best regards, Alexei -- All science is either physics or stamp collecting.
