GMP库：我们是否可以仅使用一种功能gmp_printf而不构建完整的GMP库？

Question

I am just starting with GMP for that I need to check any one function.

I downloaded gmp-6.0.tar , extracted it then I used gmp_printf in my code .

Now when I open gmp_printf.c it has a header file gmp.h . But when I search into that extracted folder its not there. So I just want that printf.c code to be linked with my native code successfully.

And I don't want complete library to be installed.

Answer 1

The header gmp.h is generated when you run configure and contains specific information on what settings you configure with. In general it is not a good idea to cut a function from its library. Especially in this case, I cannot see any way you can print GMP types without actually having them defined.

Also note that GMP is LGPLv3 and/or GPL v2.0 and by copying code like this your code must be GPL compatible.

Answer 2

Have a look at mini-gmp. It is included in the GMP source as a stand alone, portable SUBSET GMP library. :)
