Installing OpenSSL Libraries on Ubuntu for C Development
Attempting to build code utilizing OpenSSL 1.0.0 on Ubuntu 10.04 LTS, users may encounter errors indicating missing OpenSSL header files. Despite having the openssl package installed, the necessary library is not available.
To resolve this issue, the development package, libssl-dev, is required. It contains the headers and libraries needed for C development:
sudo apt-get install libssl-dev
This package includes the following headers:
- openssl/bio.h
- openssl/buffer.h
- openssl/des.h
- openssl/evp.h
- openssl/pem.h
- openssl/rsa.h
The linker typically searches the following standard system directories for libraries:
- /lib
- /usr/lib
- /usr/local/lib
- /usr/lib64 (on 64-bit systems)
By installing the libssl-dev package, the necessary headers and libraries will be made available, allowing compilation and linking of code that utilizes OpenSSL.
