OBSERVED RESULT
[58%] Building CXX object core/app/CMakeFiles/digikamcore.dir/utils/digikam_version.cpp.o
Failed to create directory /run/user/0/ccache-tmp: Permission denied

I test other build applications: Amarok git, efl-git, enlightenment-git, rage-git, terminology-git. They compile fine with Ccache.
I see Digikam ccache build begin  to write successfully in /run/user/1000
Then he tries to write in /run/user/0 
He can't because /run/user/0 belongs to root and root group
This issue happens only with Digikam 
SOFTWARE/OS VERSIONS
Ccache 4.1
Cmake 3.19.3
Linux Arch

Comment 1 caulier.gilles 2021-01-18 13:31:13 UTC

In fact, digiKam cmake rules are missing to handle ccache.

Something similar to Exiv2 must be implemented in DK :

1/ new cmake option:

 https://github.com/Exiv2/exiv2/blob/master/CMakeLists.txt#L47

2/ new cmake rules:

https://github.com/Exiv2/exiv2/blob/master/cmake/findDependencies.cmake#L53

That all...

Maik, 

For info, I assigned this file to my new student Phước Khánh Lê to start to fix some issues in bugzilla for next GoSC 2021.

Created attachment 135207 [details]
change to handle ccache in compilation Digikam

Gilles,
Inspired by code cmake for compilation of exiv2, i inserted an option to handle ccache in compilation of DK. 
For testing, i re-compiled DK with and without ccache to compare the speed. The compilation is accelerated by turning on option BUILD_WITH_CCACHE.

Comment 6 Maik Qualmann 2021-01-26 17:25:32 UTC

I don't know whether we will activate it by default, there are also bugs with ccache.

Comment 7 caulier.gilles 2021-01-26 19:35:53 UTC

Maik,

The option is disabled by default.

MXE use CCache since 2 years now to speed-up compilation, and i must admit that it work well, considerating the amont of code compiled with MXE on my computers.

So we will see step by step how last ccache version work with DK source code with users feedback.

Comment 8 maderios 2021-01-27 10:38:33 UTC

I've been using ccache for at least two years to build digikam without any problem.
I use ccache to build other git projects softwares (efl, enlightenment, linux kernel, etc...) it works fine, except with digikam *very recently*. I guess that something has changed in Digikam during last weeks.

Comment 9 caulier.gilles 2021-01-27 17:25:28 UTC

Maik,

i will release the RC this week end and we will see the feedback for few weeks before the final release.

Comment 10 maderios 2021-01-27 18:22:50 UTC

Error again with last git master today

IN Arch PKGBUILD
-DBUILD_WITH_CCACHE=ON 

Then when building:
-- Check for working CXX compiler: /usr/lib/ccache/bin/c++ - skipped
-- Looking for ccache...
-- ccache program found: /usr/bin/ccache
--  ccache found............................. YES (optional)
-- Using ccache to speed-up compilations..... YES

Odd behaviour: compilation doesn't stop at 58% but reaches about 98% then this error appear, then strangely, all messages from 58% to 98% disappear... I can't get this messages in terminal, even in a "script" file.

Precision: this odd behaviour was already present with previous git versions

Comment 12 Maik Qualmann 2021-01-27 19:24:13 UTC

Could it be that the cache is broken? Maybe just delete the directory. The problem isn't that rare when you google it. But it's always a ccache problem.

Maik

Comment 13 maderios 2021-01-27 20:33:15 UTC

A mistake from me, i didn't see the end of messages, sorry:
It builds successfully to 100% then, it seems there's a problem with package. 
After this digikam build issue, i built successfully efl library and enlightenment with ccache, no issue.
Important: 
- efl and enlightenment use meson and ninja to build, not cmake.
- amarok build uses cmake too. Compilation works normally with ccache.


Here the digikam build end :

I see these error messages in your log. Have you possibly accidentally compiled / worked as a root user, so that there are now cache files to which you have no rights? Please check it out. The problem cannot be caused by digiKam, as the current code compiles under different architectures and compilers without any problem. And Phuoc Khanh LE has also successfully compiled digiKam with ccache.

Same here. Now digiKam build successfully under Windows, Mac and Linux in CI/CD workflow, with ccache activated....

I never compile as root. As Arch user, I compile with 'makepkg', "a script to automate the building of packages". It doesn't allow to compile as root for security reason.
After deleting whole ./ccache directory, i meet same issue
Digikam is the only software i can't compile with ccache, *now*. This issue appeared only recently. It didn't exist on December 22,23 2020. I keep two digikam git versions i compiled at this date.
digikam-git-r49275.1d890ed602
digikam-git-r49281.a1645c3afe

Comment 17 Maik Qualmann 2021-01-28 10:54:31 UTC

Now I don't see anything special at "digikam_version.cpp", the header file is created in the build directory at compile time. Possibly the problem, but it was the same before. You have probably already deleted the build directory?

Maik

Comment 18 caulier.gilles 2021-01-28 11:11:38 UTC

To second Maik,

We have many header created at build time to share information in source codes. These .h are generated by cmake automatically in temporary build directory:

...with a corresponding .cpp files from source code:

-rw-r--r-- 1 gilles gilles 1928 janv. 14 17:06 digikam_version.h.cmake.in

Note the *.cmake.in files parsed by cmake and exported with populated information into the build directory.

The last changes in digikam_version.h file is to include the build date automatically when user rebuild the project. That all. Nothing special...

Yes i deleted /home/user/.ccache before compiling

Comment 20 maderios 2021-01-28 11:57:59 UTC

Wow, i deleted the build directory some days ago : 2021-01-17 
https://bugs.kde.org/show_bug.cgi?id=431658
I'll try to do it again then compile. I'm not sure it's useful...

Comment 21 caulier.gilles 2021-01-28 12:11:19 UTC

This is the cmake code used to populate the digikam_version.h with build date:

Prior this call :

https://invent.kde.org/graphics/digikam/-/blob/master/core/CMakeLists.txt#L624

...running this cmake script :


https://invent.kde.org/graphics/digikam/-/blob/master/core/cmake/modules/MacroBuildDateHeader.cmake

...and later patching header :

Comment 22 maderios 2021-01-28 19:27:16 UTC

After deleting build directory, same compiling error.

Comment 23 Maik Qualmann 2021-01-29 07:01:09 UTC

I installed ccache with the default settings of openSUSE. The cache is created in the ".cache" folder in the user directory. No problem with compilation and installation.
The only thing that strikes me is that digikam_version.cpp "is recompiled with" make install "because a new time is available. Perhaps that is the point where it fails for you because you now have no rights for the cache.

Maik

Comment 24 caulier.gilles 2021-01-29 08:52:12 UTC

You are right Maik, date build must be only updated for make not "make install". We need a rules in cmake script to prevent it. But it's a normal behaviour as make install will pass all codes to see if someting has changed.

Note, here i always use "make install/fast" to install, and i never seen this problem.

@Maderios: please change your "make install" to "make install/fast" in your build script to see if this fix your problem. Note that "make install/fast" is a standard target definition in cmake and KDE applications, it's not specific to digiKam.

It works, i can build and install Digikam with ccache this way.
I edited the end of PKGBUILD:

package() {
  cd "${srcdir}/build"
  make DESTDIR="${pkgdir}" install/fast
}

Comment 26 caulier.gilles 2021-01-29 13:59:56 UTC

Thanks for the feedback. I can close this file now.

Comment 27 maderios 2021-01-29 14:12:04 UTC

I’m going to be annoying :) but I don't understand why Digikam is the only one application that needs "make install/fast"

Comment 28 maderios 2021-05-11 07:52:11 UTC

For information:
After RTF :) , I solved issue without 'install/fast"
I created /home /user./config/ccache.conf
with inside
temporary_dir = /run/user/1000/ccache-tmp
It works for all softwares

Comment 29 maderios 2021-05-23 12:44:54 UTC

> I created /home /user./config/ccache.conf
Mistake it's :
/home/user/.config/ccache/ccache.conf
