cannot find people_detect application after build pcl

[chiaho903]

Your Environment

• Operating System and version: ubuntu 16.04
• Compiler: ccmake 3.5.1
• PCL Version: 1.8.1

Context

Hi, I was trying to run the example on the pcl tutorial/gpu/detect people. I expect that it will be built after cmake the whole pcl repository, my ccmake options is shown below:

I already turn on the BUILD_GPU and BUILD_GPU_PEOPLE, but even after I run make and make install successfully, I can't find an executable file name people_detect in the bin folder.

I also find the original code in doc/tutorials/content/sources/gpu/people_detect and try to build it, but I got the error message:
fatal error: pcl/gpu/people/include/pcl/gpu/people/people_detector.h: No such file or directory
I think maybe the reference include file is misplaced, but I still can't make the people_detect file executable.

I am so sorry to ask the question. Please tell me how to compile the source code in Ubuntu 16.04? I was trying to compile for two days.Do you have the installation process.Thank you!!

[chiaho903]

hi @libaosuan, I followed the tutorial on the pcl website here. Make sure you have install the dependencies below the page.

[libaosuan]

Thanks. I have installed the PCL.

Me too having same issue, people_detect executable file is not generated after enable BUILD_GPU ,BUILD_CUDA and BUILD_PEOPLE options .

Already raised an issue - PFB links
#2292

Any help appreciated !

[dhgokul]

Thanks for review, Please let me know how to sort out this issue !

[chiaho903]

hi @dhgokul I solved this problem by enabling the WITH_VTK option, then go to build the people_detect.cpp in the tutorial folder.
I think its because the people_detect needs something from VTK, and the files in tutorial folder won't be build in the general cmake.

Hi Chiah,

Thanks for your response, I have enabled option WITH_VTK - ON (vtk-6.2), still not able to generated people binary. If you have ccmake configuration screen shot. Please share with me. will validate once

Thanks,
Gokul

@dhgokul this is my ccmake list for pcl,

And here is the ccmake list for people_detect,

[dhgokul]

Chia,
Thanks for sharing screen-shot, it really helped me lot . In my build i am not able to see BUILD_gpu_* (example : BUILD_gpu_people) options . Any changes need to be done ?

[chiaho903]

@dhgokul in my ccmake I just press [t] to get in advanced mode, maybe you should try install ccmake, it's the GUI for cmake, the usage is the same as cmake.

[dhgokul]

Thanks chia. Now, I'm able to enable BUILD_gpu_people = ON.

Now, facing different issue like CUDA version issue as follows,
I have cuda 9.0 version only, but still it shows CMake error with cuda version

Error details :

   CMake Error at gpu/people/CMakeLists.txt:24 (if):
   if given arguments:

     "9.0" "VERSION_GREATER_EQUAL" "9.0"

   Unknown arguments specified

I have tried changing version in CMakeLists.txt file like 8.0, 9.0 and 9.1. But, it always shows the same error. Please let me know, anything missing here.

[smihael]

Which version of CMake are you using?

VERSION_GREATER_EQUAL logic is available only since CMake v3.7, whereas Ubuntu 16.04 ships only with v3.5.

[dhgokul]

@smihael Thanks ! will check
