How to install openssl cryptographic library on Lubuntu

Question

I'm trying to build cryptsetup 1.6.8 (or 1.7.0) from source using the openssl libraries instead of libgcrypt.

./configure --with-crypto_backend=openssl

I did install libssl-dev but it still gives me this error:

configure: error: You need openssl library.

Have I to install some others libraries? I searched on the web and everywhere they refer to the openssl lib for ubuntu, debian ad libssl-dev

Solution

How to install openssl cryptographic library on Lubuntu

Use:

sudo apt-get install libssl-dev

Also see What is “openssl binaries” and “openssl development package”? on the Ubuntu Stack Exchange.

@Raffaele - Well, I'm not sure... Your question was, "How to install openssl cryptographic library on Lubuntu". Perhaps you should open another question.

you're right, I forgot to mention that I'm compiling cryptsetup and it tells me configure: error: You need openssl library. even after installing libssl-dev

Update: if you want to compile cryptsetup with openssl backend, be sure to install pkg-config in addition to libssl-dev.
