Ubuntu cannot find gmp

[JerryYan97]

Hello,

When I try to install gmp on Ubuntu by using this command: sudo apt-get install gmp

it says: Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package gmp

Does anyone know what's wrong here?

Thanks!

I installed gmp on ubuntu with this command sudo apt-get install libgmp3-dev.

is the installation in the path?

Cmake is looking in these env vars: GMP_INC and GMP_LIB

See the official instruction below.

Note if cmake cannot find gmp you need to export the envirnement variable GMP_INC and GMP_LIB to the folder where you installed (e.g., \Library\include for GMP_INC and \Library\lib for GMP_LIB).

Previously I did sudo apt-get install gmp and got the same errors:

$ sudo apt install gmp
Reading package lists... Done
Building dependency tree       
Reading state information... Done
E: Unable to locate package gmp

Then, cmake gave errors about GMP_INC and GMP_LIB:

$ cmake ..
...
-- Could NOT find GMP (missing: GMP_INCLUDE_DIRS GMP_LIBRARIES) 
-- GMP libs: GMP_LIBRARIES-NOTFOUND GMP_INCLUDE_DIRS-NOTFOUND
CMake Error at CMakeLists.txt:81 (MESSAGE):
  Cannot find GMP

Thanks to @hph73, the alternative command sudo apt-get install libgmp3-dev worked for me. I didn't have to set GMP_INC, GMP_LIB myself. It just works!

$ sudo apt-get install libgmp3-dev
$ cmake ..
$ make

It built successfully after 5 minutes with a number of compiler warnings (shadowed declarations, enumeration values not handled, assume signed overflow not occur).
