Updating OpenSSL 1.1.0f to 1.1.1 from source, missing header error

I’m not sure if this is the place to ask, but I’ll give it a shot.

I’ve installed DietPi on a Raspberry Pi 3B+, to use as a web- and nextcloud server. I’d like to use HTTPS/SSL and wanted to update to the latest version of OpenSSL, the raspian repository doesn’t seem to have a later version than 1.1.0f and the latest LTS version is 1.1.1, released last month.

Here is what I did:

apt install make
apt install gcc
apt install ssllib-dev
wget https://www.openssl.org/source/openssl-1.1.1.tar.gz
tar -xvzf openssl-1.1.1.tar.gz
cd openssl-1.1.1/
./config --prefix=/usr
make

And this is the output I get:

make depend && make _all
make[1]: Entering directory ‘/root/openssl-1.1.1’
make[1]: Leaving directory ‘/root/openssl-1.1.1’
make[1]: Entering directory ‘/root/openssl-1.1.1’

So I understand that I’m missing limits.h (or at least a path to it). I’m not very at home with compiling software from source so I’m a bit at a loss here. Which limits.h am I missing? Is there some other package I need to install or can I create a link to is in some lib directory?

Seems I was missing some build tools for gcc, running:

 apt install build-essential -y

helped with that. Then running:

make
make install

went without errors. However I encountered:

openssl: /usr/lib/arm-linux-gnueabihf/libssl.so.1.1: version OPENSSL_1_1_1' not found (required by openssl) openssl: /usr/lib/arm-linux-gnueabihf/libcrypto.so.1.1: version OPENSSL_1_1_1’ not found (required by openssl)

Not sure where I get these libraries from, any suggestions?
