Hi,
I have a big RPM spec file for a project that I would like to use with CPack. I can change things in that file if needed. This specfile contains several %package tags I would like to keep. I tried to use CPack with those packages but failed. To simplify my issue, I wrote a little project with a little specfile containing two packages:
The project builds a program with a shared library:
/usr/bin/test
/usr/lib64/liblll.so
and I would like to get two rpm files, one test-test.rpm and another test-lll.rpm
In my CMakeLists.txt, I set those two lines:
install(TARGETS test COMPONENT test DESTINATION “${CMAKE\_INSTALL\_BINDIR}”)
install(TARGETS lll COMPONENT lll DESTINATION “${CMAKE\_INSTALL\_LIBDIR}”)
The idea is to have one component for one package.
In the specfile, I defined
%package test and also %package lll with
%files test
%{\_bindir}/test
%files lll
%{libdir}/liblll.so
My CMakeCPack.cmake file contains:
set(CPACK\_PACKAGE\_NAME “${PROJECT\_NAME}”)
set(CPACK\_COMPONENTS\_ALL test lll)
set(CPACK\_PACKAGING\_INSTALL\_PREFIX ${CMAKE\_INSTALL\_PREFIX})
set(CPACK\_GENERATOR RPM)
set(CPACK\_RPM\_COMPONENT\_INSTALL ON)
set(CPACK\_RPM\_USER\_BINARY\_SPECFILE “${CMAKE\_SOURCE\_DIR}/test.spec”)
After a “make package”: I get a tree that looks like:
\_CPack\_Packages/Linux/RPM/test-0.1.1-Linux/
├── lll
│ └── usr
│ └── lib64
│ └── liblll.so
└── test
└── usr
└── bin
└── test
But I cannot get my two rpm files.
CPackRPM is complaining about /usr/bin/test that does not exist in lll or usr/lib64/liblll.so that does not exist in test.
Since I specified %files for each one, I don’t understand this error. What am I doing wrong?
Regards, thank you
David.

David,
Not an expert by any means, but I have mostly wrangled CPack into submission for my project.
I can’t say this is right or not, but I install my targets in the “normal” places:
```cmake
install(TARGETS test COMPONENT test DESTINATION bin)
install(TARGETS lll COMPONENT lll DESTINATION lib64)
```
In my RPM, we install in /opt, so I also add
```cmake
# Since we are putting things in /etc and /opt, don't make this package relocatable
set(CPACK_PACKAGE_RELOCATABLE OFF)
set(CPACK_PACKAGE_INSTALL_DIRECTORY "/opt/foo")
set(CPACK_PACKAGING_INSTALL_PREFIX "/opt/foo")
```
You might also want to assert that this is a binary (not source) RPM. I don’t know how/if this interacts with specifying the binary spec file
```cmake
set(CPACK_BINARY_RPM "ON")
```
I haven’t used my own specfile; I rather found that things are a bit easier if I let CPack do what it wants to do. When I do need to exert some control,
```cmake
set(CPACK_RPM_FILE_NAME RPM-DEFAULT)
# Control the %files section
set(CPACK_RPM_USER_FILELIST
"%config(noreplace) /etc/opt/foo/foo.cfg"
"%config /etc/systemd/system/foo.service"
)
set(CPACK_RPM_EXCLUDE_FROM_AUTO_FILELIST_ADDITION
/opt
/etc/opt
/etc/systemd /etc/systemd/system
/usr/lib/python /usr/lib/python2.7 /usr/lib/python2.7/site-packages
)
```
Everything else is pretty automagic.

Hi Jim,
Thank you very much for your suggestions. It is not exactly what I was thinking about but looks very interesting.
I’ll give it a try.
