I appreciate your any comments to solve the problems. My detail procedures is as follows.

  1. Compiling and installing gmp library (with default option)

    • gmp.h is generated in /usr/local/include
    • libgmp.a, libgmp.so, libgmp.la, etc are generated in /usr/local/lib

  2. Compiling and installing paillier library (with default option)

    • paillier.h is generated in /usr/local/include
    • libpaillier.a is generated in /usr/local/lib

  3. Sample code for paillier library test

What happens if you switch the link order? That is, use input "paillier", "gmp". Especially with static libraries, link order is important.
