How to Install the LDPL Programming Language on Fedora

Recently, I stumbled across an interesting little language named the . It’s inspired by and has several neat features. However, LDPL is not as popular or well known as other languages.

(the Dinosaur Programming Language) is a language designed to be easy to understand and simple to write. Designed to be easy to learn and simple to use. We believe that coding should be easy and simple. Nothing should become a frustrating chore. Compiling source code should be easy and simple: a single, flagless command should be enough to compile any source code. Every statement in the language should do one and one thing only, not multiple things depending on the context. Complex, low level stuff like encoding, sockets, floating point number comparison, etc., should be dealt by the compiler, transparently to the user. Hard stuff should be made easier.

If you want to use LDPL, you need to follow the . However, the instructions are pretty generic. Below are Fedora specific installation instructions.

First, you need to download the latest version of LDPL via git.

git clone //github.com/Lartu/ldpl.git

Next, you need to use cd ldpl to enter the languages folder and run the make command.

In my case, I got the following error because LDPL needs to have C++ installed. I was under the impression that Fedora had C++ installed, but I was wrong.

[johnblood@itsfoss ldpl]$ make
cd src && g++ -Wall -std=gnu++11 -fpermissive -DVERSION='"4.5"'   -DVERSIONNAME='"Groovy Gualicho"'  -DCOMPILEDATE='"2021-02-07"' -DCOMPILEHOUR='"08:29:47"' -DLPMLOCATION='"~/ldpl/lpm/"' -DLDPLLIBLOCATION='"/usr/local/lib/ldpl"'  ldpl.cpp -o ldpl -static-libgcc -static-libstdc++
/usr/bin/ld: cannot find -lstdc++
collect2: error: ld returned 1 exit status
make: *** [makefile:59: all] Error 1

To install the required dependency, run sudo dnf install libstdc++-static.

Once the installation is complete, run make and then sudo make install.

You shouldn’t encounter any other errors. Once the installation is complete, you can check to make it is working by running ldpl -v in the terminal. The output should look like this:

[johnblood@itsfoss ~]$ ldpl -v

 This is LDPL version 4.5 'Groovy Gualicho'.

Update: 1-29-2022

I tried to install LDPL on a clean installation of Fedora 35 and ran into the following error:

[johnblood@fedora ldpl]$ make
cd src && g++ -Wall -std=gnu++11 -fpermissive -DVERSION='"4.5"'   -DVERSIONNAME='"Groovy Gualicho"'  -DCOMPILEDATE='"2022-01-29"' -DCOMPILEHOUR='"21:53:15"' -DLPMLOCATION='"~/ldpl/lpm/"' -DLDPLLIBLOCATION='"/usr/local/lib/ldpl"'  ldpl.cpp -o ldpl -static-libgcc -static-libstdc++
/bin/sh: line 1: g++: command not found
make: *** [makefile:59: all] Error 127

To fix this error, you need to install the gcc-c++ package via sudo dnf install gcc-c++.

Optional: Install Code Highlighting

LDPL ships with support for code highlighting for both Nano and Gedit/Pluma. To install, you need to navigate to either the /highlighting/nano or /highlighting/gedit folder. When you are in the correct folder, run ./install.sh/.
