是否可以在 C++ 代码中使用库 GMP 而无需安装它？

Question

I'm trying to build a portable project that uses a library and that library uses GMP. I am wondering if it is possible to use a statement like #include "gmpxx.h" with GMP's code in my project's directory.

Answer 1

Yes, as Marc Glisse pointed out, if performance is not so important to you, and you are not calculating with very very large numbers, GMP has a small footprint library-within-the-library version called "mini-gmp" which is almost fully compatible with the GMP interface, comprising calculations on natural numbers ( mpn ), integers ( mpz ), and rationals ( mpq ), see here and here for details. Almost all issues with mini-gmp have been fixed .

You don't ever install mini-gmp, basically you #include "mini-gmp.c" in your code (and #include "mini-mpq.c" if rational numbers required) and you are ready to go. Or just compile mini-gmp.c as a separate compilation unit and use the declarations in mini-gmp.h . Also, there's a test suite in the directory you may run with make .

Note, though, that if your application is mission-critical you may run into problems because all microarchitecture optimizations and code for arithmetic on asymptotically large numbers are not included in mini-gmp.
