Hello, I'm trying to run the example files obtained with the installation of Spinnaker sdk for ubuntu 20.04. I would like to run Acquisition.cpp, but when I try to compile it this is the error:

ubuntu@ubuntu:/opt/spinnaker/src/Acquisition$ g++ Acquisition.cpp -o Acquisition
Acquisition.cpp:42:10: fatal error: Spinnaker.h: No such file or directory
   42 | #include "Spinnaker.h"
      |          ^~~~~~~~~~~~~

---

I see the file Spinnaker.h has another directory (/opt/spinnaker/include). How can i fix this problem?

thank you

  Hello Silvia,

  With "sudo make", executable is moved to /opt/spinnaker/bin after compilation. Have you tried running the application from this bin folder? Besides, running similar command as you pointed out should generate executable in the same .Acquisition.cpp directory. i.e:

  g++ -std=c++11 -o Acquisition .obj/build/Acquisition.o -Wl,-Bdynamic -L../../lib -lSpinnaker  -Wl,-rpath-link=../../lib

  Please let me know if you find any of the above options helpful.

  Thanks,

  Ifeanyi

  Hello Silvia,

  Does it work using make file path of example directory to compile the project? i.e:

  $ sudo make 

  Thanks,

  Sorry, I didn't get how to use $ sudo make.

  I try to execute $ sudo make Acquisition and this is the output:

  ubuntu@ubuntu:/opt/spinnaker/src/Acquisition$ sudo make Acquisition
  g++ -std=c++11 -o Acquisition .obj/build/Acquisition.o -Wl,-Bdynamic -L../../lib -lSpinnaker  -Wl,-rpath-ink=../../lib
  mv Acquisition ../../bin

  but then when I try to compile I get the same error:

  ubuntu@ubuntu:/opt/spinnaker/src/Acquisition$ g++ Acquisition.cpp -o Acquisition
  Acquisition.cpp:42:10: fatal error: Spinnaker.h: No such file or directory
     42 | #include "Spinnaker.h"
        |          ^~~~~~~~~~~~~

   

  can you explain better how can I do? sorry but I'm a beginner with c++. thank you

  Hello Silvia,

  I mean to only enter "sudo make" from Acquisition directory:

  "ubuntu@ubuntu:/opt/spinnaker/src/Acquisition$ sudo make "

  I hope this helps to resolve the issue.

  Thanks,

  So this is the same I've done before since the output is :

  ubuntu@ubuntu:/opt/spinnaker/src/Acquisition$ sudo make
  g++ -std=c++11 -o Acquisition .obj/build/Acquisition.o -Wl,-Bdynamic -L../../lib -lSpinnaker  -Wl,-rpath-link=../../lib
  mv Acquisition ../../bin

  But compiling Acquisition.cpp, it still give me the same error of before.

  I also try to move Spinnaker.h in the directory /opt/spinnaker/src/Acquisition/ but permission denied.

  other ideas? thank you very much

  Hello,

  thank you very much now I got it!

  but now I'm trying again to run Acquisition in the bin folder but this error occurs:

  ubuntu@rpi-lumio:/opt/spinnaker/bin$ ./Acquisition
  ./Acquisition: error while loading shared libraries: libSpinnaker.so.3: cannot open shared object file: No such file or directory

  I see the library is in this directory opt/spinnaker/lib , so why this error?

  thank you

  Hi Silvia,

  This may be related to access permission. Does it work with below command line?

  "$ sudo -E ./Acquisition"

  Thanks,

  No, it doesn't work. same error:

  ubuntu@ubuntu:/opt/spinnaker/bin$ sudo -E ./Acquisition
  ./Acquisition: error while loading shared libraries: libSpinnaker.so.3: cannot open shared object file: No such file or directory

  is there another solution?
