tar value <uid> out of uid_t range 0..2097151

[harpreetsc1992]

Hello,
I am trying to build keystone and am building this version of the tool - a1842a1 - on an x86 machine, so that I can run it with gem5. I'm building on the 5.15.0-100-generic kernel, and it is an Ubuntu distribution. The machine is a Intel(R) Core(TM) i5-8500 CPU @ 3.00GHz model.

The steps that I have performed up until now are:
git clone https://github.com/keystone-enclave/keystone.git
cd keystone
git checkout a1842a1
./fast-setup.sh
source source.sh
mkdir build
cd build
cmake ..
make

On doing make, I get the following error:
[ 34%] Generating pkg/eyrie-rt

The ######### is a uid assigned to me by my university, a 9 digit number, which also happens to be my UIN (that is why I have hidden it).

My tar version is GNU tar 1.34.

Why is tar blocking on a big number in the script? And how can I mitigate this error? Any help would be useful.

Thanks

I did find a solution that is working for me. In sdk/macros.cmake, the makeself command can be changed to:
COMMAND
${MAKESELF} --tar-extra "--owner=0 --group=0" --noprogress ${pkg_dir} ${package_name} "Keystone Enclave Package" ${package_script_raw}

I believe this will even be applicable to the latest branch too.
