0011656: CPackRPM: Support dependency between RPM component
As of CPack 2.8.4 the RPM component support is very basic,
no dependency between components are handled.

We should support this.

Attached a patch for CPackRPM.cmake in 2.8.6 to define different RPM spec headers for different components e.g. CPACK_RPM_mycomponent_PACKAGE_PROVIDES, CPACK_RPM_mycomponent_PACKAGE_REQUIRES

Just merged a modified version of the provided patch to next.
Thank you very much for that.
With that addition the dependency between components is not [yet] automatic
but at least it can be specified by hand.

Merge topic 'CPackRPM-perComponentHeader' into next

e20c59a CPackRPM support component specific variables for spec files.

I attach a patch for CPackRPM.cmake (2.8.12) that creates the inter-component dependencies. It needs review and testing, I have just tested it with my software and it worked.

Barthelemy could you provide a working example for you.

The patch looks OK but shouldn't work in all grouping case,
see: http://www.cmake.org/Wiki/CMake:Component_Install_With_CPack#Controlling_Differents_Ways_of_packaging_components [^]

Moreover I think tha currently the definition of
"CPACK_COMPONENT_${CPACK_RPM_PACKAGE_COMPONENT}_DEPENDS"

is case sensitive, may be one should always use
string(TOUPPER ${CPACK_RPM_PACKAGE_COMPONENT} UPPER_COMPNAME)

instead of CPACK_RPM_PACKAGE_COMPONENT.

Beware not to mix tab and space in you patch/source modification.
Use space only (no tab) please.

Hello,

Sorry for the excessive delay in my reply. Next iteration will be faster.

For the grouping cases, I am not sure what is missing.
1. ALL_COMPONENTS_IN_ONE : CPACK_RPM_PACKAGE_COMPONENT is false, my code is ignored. My debug output should actually be within the if, I will change that.
2. IGNORE : it successfully process the dependencies considering that there is one package per component.
3. ONE_PER_GROUP : this case is not handled for RPMs. I see that if I declare groups and use this option I still get 1 rpm per component. Thus it is equivalent to IGNORE. If a day it is implement, then we should of course adapt the code.

For the casing of "CPACK_COMPONENT_${CPACK_RPM_PACKAGE_COMPONENT}_DEPENDS" I would not change it. First, it doesn't work anymore if I do so, possibly because it is at some point compared with CPACK_COMPONENTS_ALL. Second, if it is case sensitive there is no obvious reason to make it case insensitive (by putting it all uppercase). Users should be careful to have consistent components naming e.g. core != CORE != Core.

I will change the tabs into spaces, sorry about that.

I will shortly upload a new diff with the 2 changes mentioned above and a simple working example.

Best regards

Hi again,

I made a mistake. ONE_PER_GROUP option works and must be handled. I will do it.

Sorry for the confusion.

Maybe I will also understand the "upper case" thing soon :)

Please find attached a new diff. It contains changes to CPackRPM.cmake implementing dependencies between components.
It handles the different CPACK_COMPONENTS_GROUPING. The code is more complicated due to that.
I tested it for various cases such as group-less components, dependencies between components of the same group or multiple dependencies from one group to another.

The working example I use is unfortunately copyrighted by my company. I can send it to you Eric Noulard for test purpose but can't post it here. Would it be ok like this ?

Best regards,
Barth

Domen,

Would you be kind enough to have a look at Barthelemy proposal?

Sorry for the late response...

I've looked the patch and tested it with the tests that come with CMake.
I haven't yet tested it allot but it doesn't work with the tests that come with CMake. Tests pass but only because generated RPM files are not semantically checked a whole lot (diffs of generated spec files are more revealing).

There are a few obvious problems:

1)
SET(CPACK_RPM_${CURRENT_PKG}_PACKAGE_REQUIRES "")

This line unsets the value that is provided by the user and thus breaks back compatibility.

CMake file Tests/CPackComponentsForAll/MyLibCPackConfig-OnePackPerGroup.cmake.in contains set(CPACK_RPM_Development_PACKAGE_REQUIRES "mylib-Runtime") and even though this variable name is not documented it is present in tests and usable in the past so I would say that the back compatibility should be preserved.

2)
All if(DEFINED *) and if(NOT DEFINED *) tests should be replaced by if set checks (just delete DEFINED) since even if a variable is defined it can still contain an empty string and such values should be ignored as well to prevent "Requires: , some_value" variable contents.

3)
Even if I remove DEFINED values I still get "Requires: ," and "Requires: " values in spec files.

Could you also fix the above cases?
