How to install gprbuild on Linux - Centos7

Question

I have recently dowloaded GNAT Community on my Linux machine (Centos7).

Within /home/parallels/opt/GNAT/2019 there is a folder gprbuild, my understanding is that to install this I need to execute the bootstrap.sh script that is located within gprbuild: /home/parallels/opt/GNAT/2019/gprbuild/bootstrap.sh

I try to execute the bootstrap.sh script like so...

[parallels@localhost gprbuild]$ ./bootstrap.sh

Then I recieve this error message...

./bootstrap.sh: line 87: gnatmake: command not found

Here is the bootstrap.sh script...

# bootstrap.sh - a simple bootstrap for building gprbuild with xmlada

  --build            build only but do not install

I have been told that I need to install xmlada prior to installing gprbuild, then I have read elsewhere that I need to install gprbuild to be able to install xmlada!

I have a similair issue when attempting to install xmlada, the shell script within the xmlada folder is called install-sh, when I attempt to install this I am told there is no input file specified...

[parallels@localhost xmlada]$ ./install-sh
./install-sh: no input file specified.

I apreciate this is really two questions in one, but I felt I had to explain it this way, as I am unsure which library needs to be installed first, and also how do I actually install them.

Any help would be greatly apreciated! I hope you're all having a good weekend... :)

Thanks, Lloyd

Just install gcc-ada, or search in your package manager for gcc-ada (may change its name), gnat* commands come in this package
