How to know more about RDM indexing errors ?

[fperies]

Command 'rc -g' reports the following:

[ 81%] 17/21 15:47:32 ~/repo/gnb/uplane/sct/tickler/cpp_testsuites/l2ps/tc/baseline/bl_LoopCellGroupSetupDelete.cpp error in 18ms.  (dirty). (priority 2)
[ 86%] 18/21 15:47:32 ~/repo/gnb/uplane/sct/tickler/cpp_testsuites/l2ps/sctl2ps_support.cpp error in 19ms.  (dirty). (priority 2)

How to find out what is behind those errors ?
Is there any trace I can activate to know more about this issue ?

Thanks

You could try rdm -vvv.

I've already tried without any success:

*********************************

*********************************
Running a release build
socketFile: /ebs/frperies/.rdm
dataDir: /dev/shm/rtags/
options: 0x40080001c
jobCount: 16

I understand I run into the following condition:

Is there any more accurate way to find out what is missing in the DB ?

UPDATE
I've just added the dump of variable hasUnit and it is false:
[ 96%] 26/27 11:48:52 ~/repo/gnb/uplane/sct/tickler/cpp_testsuites/l2ps/sctl2ps_support.cpp error (hasUnit(0)) in 26ms. (dirty). (priority 2).
But I've also checked this file is effectivily in DB (extract from file compile_commands.json):
....
{
"directory": "/ebs/frperies/repo/gnb/uplane/build/tickler",
"command": "/ebs/frperies/repo/gnb/uplane/sdkuplane/prefix-root-list/asik-x86_64-ps_lfs-dynamic-linker-on/usr/bin/x86_64-pc-linux-gnu-g++ --sysroot=/ebs/frperies/repo/gnb/uplane/sdkuplane/prefix-root-list/asik-x86_64-ps_lfs-dynamic-linker-on/toolchain/sysroots/core2-64-pc-linux-gnu ... -include /ebs/frperies/repo/gnb/uplane/build/tickler/cpp_testsuites/l2ps/tc/CMakeFiles/sctl2psTemplatesVars.dir/cmake_pch.hxx -o cpp_testsuites/l2ps/CMakeFiles/sctl2ps_support.dir/sctl2ps_support.cpp.o -c /ebs/frperies/repo/gnb/uplane/sct/cpp_testsuites/l2ps/sctl2ps_support.cpp",
"file": "/ebs/frperies/repo/gnb/uplane/sct/cpp_testsuites/l2ps/sctl2ps_support.cpp"
},
...

How is it possible to get hasUnit to false while file is in the DB ??

Also I've just noticed that maybe some symbols is causing the issue because I get an error prior to the first error of this post:
Error during validation: /ebs/frperies/repo/gnb/uplane/sct/tickler/cpp_testsuites/l2ps/sctl2ps_support.cpp /dev/shm/rtags/%2Febs%2Ffrperies%2Frepo%2Fgnb%2F/6800/symbols doesn't exist

@cslux : I think I found the issue : this is due to the following include option in compilation command:

-include /ebs/frperies/repo/gnb/uplane/build/tickler/cpp_testsuites/l2ps/tc/CMakeFiles/sctl2psTemplatesVars.dir/cmake_pch.hxx

If I remove this option the error goes away.

It seems that this .cxx file is not indexed according to the following trace:
Shouldn't index /ebs/frperies/repo/gnb/uplane/build/tickler/cpp_testsuites/l2ps/tc/CMakeFiles/sctl2psTemplatesVars.dir/cmake_pch.hxx.cxx because of exclude filter

That is .cxx files are part of the exclude filter by default.
The question now is : how do I remove .cxx files from exclude filter ?

Thanks again for your support !

[fperies]

So, I've used the --exclude-filter RDM's option as follows:
--exclude-filter="/cmake/Modules/;/conftest.c*;/tmp/;/private/tmp/;/private/var/*"
and the Shouldn't index message goes away but unfortunately errors are still there.

So, for some reasons the "-include" option in compilation command does not work....

I'm still looking forward your opinion on this topic.

Thanks

Hi @fperies can you have a steps to reproduce this issue? If so, I would like to have a try if it is not too complex.

[fperies]

Hello @zhihuiFan,

My understanding is that RTags does not support compilation commands where the CMake feature precompiled headers has been used.
I'm not a CMake expert but I think that if the CMake macro target_precompile_header() has been used in file CMakeLists.txt then it will add both a warning (-Winvalid-pch) and a preprocessor include directive (-include <path_to_precompiled_header>/cmake_pch.hxx) to the compilation command line of the associated CMake target.
Knowing that, if you want to reproduce it, you have to set up a CMake target with a precompiled header (by using the macro target_precompiled_header()) and then try to index it with RTags. Of course, you will need also to remove string "/CMakeFiles/" from RTags --exclude-filter option as I did above, because CMake put the precompiled headers in some /CMakeFiles/ path within build directory. Then, you should hit the error I've described at the beginning of this issue.

Otherwise, I've found a workaround by using the CMake flag:

but I can not really say if it is acceptable in all situations.

Let me know if you need additional information.
Thanks !

Hi @fperies :

Actually I was expecting an reproduce steps like

git clone xxxx/demo.git
cmake --version
cmake ..
rc -J .
balabala...

Maybe the steps like above is not easy, and I didn't use CMAKE in my real work, so it would be hard to provide help.
