[CMake] Cpack generated RPM and changed binary file size in 2.8.10
Hi, I have a wired situation, I have a binary file (ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped) in bin directory, I then I run cpack -G RPM to generate an RPM package. After install the RPM package in another machine, the size of the binary file (82576 KB) is different from original binary file (106228 KB). Some functions in that packaged binary file did not run correctly. Could anyone help to explain me why the size of binary file changes? And how to fix it? Thank you.

After install the RPM package in another machine, the size of the binary file (82576 KB) is different from original binary file (106228 KB). Could you check the size of the executable which gets into the RPM it should be located in: builddir/_CPack_Packages/packageName/RPM/packageFileName/ When CPackRPM runs you get a message like: CPackRPM: Will use GENERATED spec file: /blah/blah/.../RPM/SPECS/yourpackage.spec then the directory to look into should be: /blah/blah/.../RPM/packageFileName/ You can also extract the content of the generated RPM using rpm2cpio (or alien) rpm2cpio yourpackage.rpm | cpio -idmv alien -t yourpackage.rpm tar zxvf yourpackage.tgz then verify the size of the concerned file. Some functions in that packaged binary file did not run correctly. Could anyone help to explain me why the size of binary file changes? I bet you compare with a file produced by make install/strip? a) The executable your are looking at may not be the same as the one put into the RPM. b) rpmbuild (which get called by CPackRPM) can post-process the library/executable depending on the distribution you are running on. So first do the comparison with the package executable. Then more questions: 1) On which kind of hosts do you create the RPM? (Fedora Y, OpenSuSE W, Debian Z, etc...) What is the version of RPM on this one: rpm --version 2) On which king of target do you intsall it? What is the version of RPM on the target: rpm --version In each case could check the dependency found in the RPM: rpm -qp --requires yourPackage.rpm And how to fix it? Depending on the discrepancy between the host and the target this may not be fixable. Thank you.

No, I did not run make install/trip. I used CMake ExternalProject to copy the whole bin directory in configure command, and run echo in make and make install command.

The binary file size had already changed in build _CPack_Packages directory.
