I want to build a rpm package from a spec file(hello-world.spec).The command and error output are given below Command1:

rpmbuild -ba hello-world.spec

ErrorOutput1:

+ 
: not foundm-tmp.z4GoQn: 28: /var/tmp/rpm-tmp.z4GoQn:

RPM build errors:

Content of my spec file is

%description
This is my first RPM package, which does nothing.

%prep
# we have no source, so nothing here

%build
cat > hello-world.sh <<EOF
#!/usr/bin/bash
echo Hello world
EOF

%install
mkdir -p %{buildroot}/usr/bin/
install -m 755 hello-world.sh %{buildroot}/usr/bin/hello-world.sh

%files

Command2:

Can anybody help on this issue?

Check how your files is being generated. If you are passing files from windows to Linux, usually, there are different EOL for the files. We had a similar issue, I recommend you to change all the files to Unix format. I'm sharing with you how to reproduce your issue, if you edit that file in a Linux environment, like "nano", the problem disappears.
