python ethereum pyethapp Failed building wheel for scrypt

0 votes

My compilation terminated 2 times when installing pyethapp on Ubuntu.

Firstly, I installed packages:

apt-get install build-essential automake pkg-config libtool libffi-dev libgmp-dev

I made virtualenv and tried to install pyethapp inside venv with pip:

pip install mytheapp

but it crashed with 2 following errors:

1.)

#include <openssl/aes.h>
                           ^
  compilation terminated.
  error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

  ----------------------------------------

2.)

    scrypt-1.2.0/libcperciva/crypto/crypto_aes.c:6:25: fatal error: openssl/aes.h: No such file or directory
     #include <openssl/aes.h>
                             ^
    compilation terminated.

apt-get install openssl
