Hi everyone,
I've tried two methods to build binary rpm files:
-- from source tarball, and
-- from precompiled executables.
In both cases, the rpm file I built can be installed properly.
In the second case, I compiled "~/hello/src/helloworld" from source, then I copied it to the rpm in the "install" section of the spec file. Therefore, I expect to see exactly the same binary if I install this rpm. Yet the binary installed thru the rpm (/usr/bin/helloworld) and ~/hello/src/helloworld are different in file size, althrough they both run properly.
Below is the workhorse part of my spec file.
Code:
%prep
%setup -q
%install
rm -rf $RPM_BUILD_ROOT
install -m 755 -d $RPM_BUILD_ROOT%{_bindir}
cp /home/doris/hello/src/helloworld $RPM_BUILD_ROOT
chmod 755 $RPM_BUILD_ROOT/helloworld
cp $RPM_BUILD_ROOT/helloworld $RPM_BUILD_ROOT%{_bindir}
%clean
rm -rf $RPM_BUILD_ROOT
%files
%defattr(-,root,root)
%{_bindir}/*
%doc README ChangeLog AUTHORS INSTALL
Below is the size info of my two binaries.
Code:
[doris@cheetah src]$ ls -l /usr/bin/helloworld
-rwxr-xr-x 1 root root 4127 Aug 6 18:22 /usr/bin/helloworld
[doris@cheetah src]$ ls -l helloworld
-rwxrwxr-x 1 doris doris 16264 Aug 6 18:15 helloworld
Thank you for looking at my question. Any help is very much appreciated.
