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

[SergioRAgostinho]

Based on this comment seems like we're not respecting the minimum required cmake version for the project. Regarding the application install location we'll still need to look into it.

Based on this comment seems like we're not respecting the minimum required cmake version for the project. Regarding the application install location we'll still need to look into it.

In my CMakeLists
cmake_minimum_required(VERSION 3.1 FATAL_ERROR)
My CMake version:
cmake version 3.5.2

Still getting the same error.

Any resolutions?

PS- The gpu/people file that it references is this: @line24
