LinuxQuestions.org - Add precompiled binary to a rpm file

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.
