The third line here made me smile
:)

But... at the very end :

Code: Select all

and many more ; here are the complete last lines from the 'make' stdout :
http://pastebin.com/raw/8MjVWiaR

Ending with the related error :
"collect2: error: ld returned 1 exit status"
It seems that the linking step in the build process encountered some issues.

Exactly the same error appears when Linking CXX executable for ccViewer.


Some more informations :

This was the cmake-gui entries containing the word 'las' :

Here are the contents of these two directories :
$ tree /usr/include/liblas/
http://pastebin.com/raw/k97XM40Q

and :
$ find /usr/lib -iname "*liblas*"
/usr/lib/liblas.so
/usr/lib/python2.7/dist-packages/liblas
/usr/lib/python2.7/dist-packages/libLAS-1.8.0.egg-info

/usr/lib/liblas_c.so.3
/usr/lib/liblas_c.so.2.3.0
/usr/lib/liblas_c.so
/usr/lib/liblas.so.3

It's liblas1.8.0, freshly installed from the Xenial official repositories. All theses packages are installed :

Code: Select all

$ sudo apt-cache search liblas | grep -i lidar
liblas-bin - ASPRS LiDAR data translation toolset
liblas-c-dev - ASPRS LiDAR data translation library - C development files

liblas3 - ASPRS LiDAR data translation library - C++ version
python-liblas - Python module to use the ASPRS LiDAR data translation library
I do not feel I'm wrong somewhere but who knows...

Thanks a lot !

The cmake liblas_library_file variable should point to the actual library file (.a or. so) not the folder.

Hello,

It's now ending correctly !!
Thanks a LOT !

( > CC is really slow.... it has taken more than 20min to compute normals on a 45 Mpts points clouds and just moving and rotating the cloud around is lags like hell )


But as I never come empty-handed here are a few new questions :

1) The changes you committed to github were on the 2.8 beta.
Will you also upgrade the 2.7 version we can found here on the release page : https://github.com/cloudcompare/trunk/releases ?

2) CC 2.8 beta comes without qCANUPO, is it normal ?
How to add this plug-in ?
Is it available in 2.7 ?
Answer is : no, it's not natively available. Here is what is in the plugin dir of the 2.7 release :

Code: Select all

$ tree -L 1 -d ./
./
├── qAnimation
├── qBlur
├── qCork
├── qCSVMatrixIO
├── qDummyPlugin
├── qEDL
├── qFacets
├── qGMMREG
├── qHPR
├── qKinect
├── qPCL
├── qPCV
├── qPoissonRecon
├── qRANSAC_SD
├── qSRA
└── qSSAO
2.5) Same question about qM3C2 which is also not there.
Answer same as above.

3) I noticed the following libraries have almost the same name :
Image
Do we need both or could we drop the two OPENNI entries (without the '2') ?


4) ☑ [FIXED BY wpqjbzwm] If I enable INSTALL_QCSF_PLUGIN in cmake-gui, configure and generating outputs seem the same as before, nothing new.
But when making the software it comes a new issue with strange characters...
As this error is related to this particular plugin I will post in a new dedicated thread in the plugins section :
viewtopic.php?f=17&t=1825&sid=5f23424f7 ... 7d9796060a


Thanks a lot again for your work ! ;-)

0) Slow CC: are you sure you are not compiling in debug mode? Otherwise the normals computation time highly depends on the kernel size (radius). And the display depends on your graphic card and/or driver

1) The 2.7 release corresponds to a given tag (https://github.com/cloudcompare/trunk/r ... tag/v2.7.0). It is not modified after this point. However the 2.8.beta version is online (and I update it from time to time).

2) Indeed, qCanupo and M3C2 sources are not public yet. Canupo is only shipped as a binary with the Windows version for now. Hopefully the sources will be released soon...

3) OpenNI is an optional dependency of one of the library we use (I believe it's PCL?). It is not used by CC and therefore it's not necessary to set these variables!

4) The strange characters were chinese comments ;)

Hi,

Yes CC is really really slow, I don't know why, there is absolutely no overloads in memory or CPU usage. (this is strange in fact).
Edit : yes 1 CPU is running at 100% during the move of the cloud for example.

Just moving the cloud or rotate it is very slow.

The compile mode was : "release".
I didn't touch any exotic features or whatever.
I compiled it as simple as can be.
I'll check if I can test the graphic card, but with the new 'radeon' driver, there is not much informations I can find to watch actual running speeds or so... And this is a pain : http://www.omgubuntu.co.uk/2016/03/ubun ... iver-16-04 :-(


Thanks for the other answers about plugins =) it's clear now.
Openni is used by PCL yes.

Regards.

What OpenGL manufacturer and version is displayed in the console? (should be near the beginning when you start)

Sorry I was referring to CC's own console (press F8 if it doesn't appear by default)

MESA is an emulation of OpenGL... you are not using your graphic card driver here.
