high cpu with version 5.4

Post by bobcat » Tue Apr 22, 2014 4:54 pm

Hello,

I tried to use Codelite 5.4.
The process consumes 100% CPU (one of the cores). GDB shows that it constantly creates new threads with fork(). I tried to stop process several times and it the backtrace shows that process somewhere in TagsManager::StartCodeLiteIndexer():

It seems that codelite_indexer could not be started on your machine.

1. Is it a self compiled codelite?
2. Do you have /usr/bin/codelite_indexer binary installed?
3. Does it start? (try to start manually)

Yes, it is self compiled version.
indexer exists, but it missing libraries from wx:

ldd /usr/bin/codelite_indexer
linux-vdso.so.1 => (0x00007fff733ff000)
libwx_gtk2u_core-3.0.so.0 => not found
libwx_baseu-3.0.so.0 => not found
libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x0000003be7400000)
libm.so.6 => /lib64/libm.so.6 (0x0000003bdb000000)
libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x0000003be6000000)
libpthread.so.0 => /lib64/libpthread.so.0 (0x0000003bdb800000)
libc.so.6 => /lib64/libc.so.6 (0x0000003bdb400000)
/lib64/ld-linux-x86-64.so.2 (0x0000003bdac00000)

So, the issue is not related to codelite.
Thanks for help.

I checked the codelite binary.

ldd /usr/bin/codelite | grep wx
libwx_gtk2u_aui-3.0.so.0 => /usr/local/lib/libwx_gtk2u_aui-3.0.so.0 (0x00007fec93e53000)
libwx_gtk2u_propgrid-3.0.so.0 => /usr/local/lib/libwx_gtk2u_propgrid-3.0.so.0 (0x00007fec93b3c000)
libwx_gtk2u_stc-3.0.so.0 => /usr/local/lib/libwx_gtk2u_stc-3.0.so.0 (0x00007fec936ff000)
libwx_gtk2u_xrc-3.0.so.0 => /usr/local/lib/libwx_gtk2u_xrc-3.0.so.0 (0x00007fec933cc000)
libwx_gtk2u_html-3.0.so.0 => /usr/local/lib/libwx_gtk2u_html-3.0.so.0 (0x00007fec930cd000)

libwx_gtk2u_core-3.0.so.0 => /usr/local/lib/libwx_gtk2u_core-3.0.so.0 (0x00007fec921e2000)
libwx_baseu_xml-3.0.so.0 => /usr/local/lib/libwx_baseu_xml-3.0.so.0 (0x00007fec91faf000)
libwx_baseu_net-3.0.so.0 => /usr/local/lib/libwx_baseu_net-3.0.so.0 (0x00007fec91d72000)
libwx_baseu-3.0.so.0 => /usr/local/lib/libwx_baseu-3.0.so.0 (0x00007fec91930000)
libwxsqlite3.so => /usr/lib64/codelite/libwxsqlite3.so (0x00007fec91660000)

The libraries missing in indexer were linked correct into codelite binary.
Is there any difference in build process between codelite and codelite_indexer?

Thanks in advance

RPATH settings. But I am pretty sure that RPATH should be applied to all binaries
I will double check this

What do you get when run:

Code: Select all

readelf -d /usr/bin/codelite_indexer |grep RPATH

RPATH in codelite_indexer is missing one directory:

readelf -d /usr/bin/codelite_indexer | grep RPATH
0x000000000000000f (RPATH) Library rpath: [/usr/lib64/codelite:/usr/lib64/codelite]

readelf -d /usr/bin/codelite | grep RPATH
0x000000000000000f (RPATH) Library rpath: [/usr/lib64/codelite:/usr/lib64/codelite:/usr/local/lib]

Its not missing it...
If the wx is installed under /usr/local/lib then it means that it is a self compiled wxWidgets, and _you_ should have add it to your LD_LIBRARY_PATH
In other cases:
1. If it is a binary provided by us, then we also copy the wxWidgets libraries to /usr/lib/codelite/, so the RPATH is enough
2. If it is a distro wxWidgets library, then it will be placed under /usr/lib - which is also fine

In your case, you compiled wxWidgets and installed it into /usr/local/lib, so you need to add it to your LD_LIBRARY_PATH

The only question remaining is: how did /usr/local/lib got into codelite binary...

wxWidget is indeed self compiled.
LD_LIBRARY_PATH is a good workaround.

How can it possible to track the source of /usr/local/lib?
Does CMake has any log files?

Hi,
How can it possible to track the source of /usr/local/lib?
That path is the default for a wxWidgets build (and, more generally, for most app builds on most Linux distros). To change it, configure with --prefix=/usr/ to install into /usr/lib/ (risks clobbering, or conflicting with, wx packages) or, as I do all the time:

Code: Select all

mkdir builddir && cd builddir && ../configure --prefix=$(pwd) --whatever-else
to 'install' to a subdir of the wx source. Then 'make' but don't 'make install'. This has the great advantage that it doesn't conflict with anything, and make it easy to have multiple wx build-types (just build each in a different subdir) and versions. However its disadvantage is that you have to specify the path to that build when you build with wx; I usually prepend it to that terminal's $PATH, or specify it in that CodeLite project configuration's compile/linker settings.

Regards,

David
