0013019: The ZIP package generator does not find the files when CPACK_PACKAGING_INSTALL_PREFIX is set
I use components and generate one binary package ZIP for each component. If CPACK_PACKAGING_INSTALL_PREFIX is not set, everything works as expected. But when I set CPACK_PACKAGING_INSTALL_PREFIX to "/MyPrefix", the package generator is unable to find the files when compressing, resulting in the error message:

CPack: Create package
1>CPack Error: ERROR while packaging files: archive_read_disk_entry_from_file: (Empty error message)
1>CPack Error: Problem compressing the directory
In CMakeLists.txt:

In CPackProjectConfig.cmake:

"C:\Program Files\CMake 2.8\bin\cpack.exe" -C Debug --config ./CPackConfig.cmake
In Source\CPack\cmCPackGenerator.cxx line 849:

           localFileName =
                cmSystemTools::RelativePath(InstallPrefix, fit->c_str());
            localFileName =

Now, when CPACK_PACKAGING_INSTALL_PREFIX is NOT set, fit is "C:/MyPath/_CPack_Packages/win32/ZIP/MyPackage-win32/core//bin/MyLib.dll" and InstallPrefix is "C:/MyPath/_CPack_Packages/win32/ZIP/MyPackage-win32/core/”.
Note the double slash in fit, it looks strange. After line 849 has executed, localFileName is "/bin/MyLib.dll”. Then, line 851 removes the leading slash, leaving "bin/MyLib.dll” in localFileName, and everything works.

However, if I set CPACK_PACKAGING_INSTALL_PREFIX to "/MyPrefix", then at line 849 above fit is "C:/MyPath/_CPack_Packages/win32/ZIP/MyPackage-win32/core/MyPrefix/bin/MyLib.dll" (note: no double slash in the path) and InstallPrefix is "C:/MyPath/_CPack_Packages/win32/ZIP/MyPackage-win32/core/MyPrefix". Line 489 sets localFileName to “bin/MyLib.dll” (which is the correct file name), but then line 851 strips of “bin/”, leaving just “MyLib.dll” in localFileName. That path will not be found later on.

But there also seems to be other problems in the code. The CPACK_PACKAGING_INSTALL_PREFIX doesn't seem to be taken into account futher down when the ZIP archive is created. Is the prefix parameter of the AddFile call suppose to be used for this?
No tags attached.

Archive generators does not use (or handle) properly
and in fact may be they can't because the prefix is meant to be some
absolute path (as used by DEB or RPM generators)

(as does NSIS generator) but again, they don't.

Note that this is not "component-related" this does not work with MONOLITHIC
package either!!

There are some related bugs to this I'll try to add links
and better explanation later.

Are you sure about that? This problem was not present in CMake 2.8.4. In that version, setting CPACK_PACKAGING_INSTALL_PREFIX added the prefix to each of the files in the resulting zip archive, as expected.

Even in CMake 2.8.7, CPack will add CPACK_PACKAGING_INSTALL_PREFIX to the paths of the files collected under _CPack_Packages. The problem is that it uses the wrong file names when it later tries to create the zip archive.

I looked at the diff between 2.8.4 and 2.8.7, and there are changes all over the place. However, I suspect that the changes to cmCPackGenerator::InstallProjectViaInstallCMakeProjects play a role. That single function is almost 400 lines (!) and has grown almost 100 lines between 2.8.4 and 2.8.7.

Since you obviously tracked down a regression,
I'm not sure :-]

The growth of code in InstallProjectViaInstallCMakeProjects, comes
from addition of Component Support and many bug fixes.

This is no excuse but we obviously miss a systematic test for the
I'll try to look into that, but If you are willing to try a patch
I'll happily review it.

What I'm [almost] sure is that:


may not be what you want in archive generator?
Are you really wanting to create a ZIP or TGZ
with an absolute path in it?
Harald Winroth

No, I don't want an absolute path in my zip. What I want is to insert a prefix so that the zip unpacks as ./MyPrefix/bin, ./MyPrefix/lib etc, instead of just ./bin and ./lib.

Setting CPACK_PACKAGING_INSTALL_PREFIX to "/MyPrefix" (with a leading slash) does just that in 2.8.4. The prefix is appended to _CPack_Packages/win32/ZIP/MyPackage-win32, so it need to include that leading slash.
2012-03-06 16:43   
Ok then this way of using it with archive generator is awkward
at best because you should usually use CPACK_PACKAGE_INSTALL_DIRECTORY
for this purpose and not CPACK_PACKAGING_INSTALL_PREFIX.

Moreover requiring the leading slash is really odd...

That said may be for Archive generator
should be used the same way as

Could you create a small standalone test case for that, I'll try
to integrate it in the test suite...
and may be dissect a little further
in order to find when exactly the behavior changed?

May be you already did that?
You said 2.8.4 was OK and 2.8.7 is not.
How are 2.8.5 and 2.8.6? (and may be 2.8.3)?

The way archive generator are handled changed drastically in 2.8.2
when the switch to libarchive was done.

Sending old, never assigned issues to the backlog.

(The age of the bug, plus the fact that it's never been assigned to anyone means that nobody is actively working on it...)

If an issue you care about is sent to the backlog when you feel it should have been addressed in a different manner, please bring it up on the CMake mailing list for discussion. Sign up for the mailing list here, if you're not already on it: [^]

It's easy to re-activate a bug here if you can find a CMake developer who has the bandwidth to take it on, and ferry a fix through to our 'next' branch for dashboard testing.
