How to Fix: Could not find OpenSSL Error in Ubuntu and Other Linux

1 min


Here’s how you can fix the “could not find OpenSSL” error in Debian, Ubuntu, Fedora and Arch Linux.

Thousands of open-source applications use the OpenSSL library to implement features which require secure connectivity between components over the web. Hence it’s a critical package and is needed when compiling any source package that implements OpenSSL.

If you don’t have it in your system, you may run into this error during compilation.

-- Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY OPENSSL_INCLUDE_DIR) (Required is at least version "0.9.7")
-- Could NOT find WolfSSL (missing: WOLFSSL_LIBRARY WOLFSSL_INCLUDE_DIR) (Required is at least version "3.4")
-- Could NOT find MbedTLS (missing: MBEDTLS_LIBRARY MBEDTLS_INCLUDE_DIR) (Required is at least version "1.3")
CMake Error at CMakeLists.txt:258 (message):

For Fedora, CentOS, RHEL and related distributions, use the below.

sudo dnf install openssl-dev

For Arch Linux, use the following command to install it.

sudo pacman -S --needed openssl

After you install it, you can now run your compilation which caused the error.
