How to install gprbuild on Linux - Centos7 - linux

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
progname=bootstrap
prefix=/usr/local
bindir=/bin
datarootdir=/share
libexecdir=/libexec
srcdir=$PWD
xmlada_src=../xmlada
CC=${CC:-cc}
GNATMAKE=${GNATMAKE:-gnatmake}
CFLAGS=${CFLAGS:-$CFLAGS}
GNATMAKEFLAGS=${GNATMAKEFLAGS:--j0}
usage() {
cat >&2 <<EOF
usage: $progname [options]
Options [defaults in brackets]:
--prefix=DIR installation prefix [$prefix]
--bindir=DIR user executables [PREFIX/bin]
--libexecdir=DIR program executables [PREFIX/libexec]
--datarootdir=DIR read-only arch.-independent data root [PREFIX/share]
--srcdir=DIR source code path [$PWD]
--with-xmlada=DIR xmlada source path [$xmlada_src]
--build build only but do not install
--install install only, skip build steps
Environment variables:
CC specify C compiler [$CC]
CFLAGS set C and Ada compilation flags [$CFLAGS]
DESTDIR optional for staged installs
GNATMAKE specify gnatmake Ada builder [$GNATMAKE]
GNATMAKEFLAGS additional Ada builder flags [$GNATMAKEFLAGS]
EOF
exit 0
}
error() {
printf -- "%s: $1" "$progname" "${#:2}" >&2
exit 1
}

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
