Exporting my function to Matlab - explanations are outdated about gtsam HOT 9 CLOSED

@etamarlu I made some updates to the project template file. Can you please clone the latest main branch and try again?

from gtsam.

Thanks, I tried it now, std namespace is not recognized, it fails with the following error:

In file included from /home/et/gtsam-project-matlab-main/example/PrintExamples.cpp:18: /home/et/gtsam-project-matlab-main/example/PrintExamples.h:57:6: error: variable or field ‘consumePrinter’ declared void 57 | void consumePrinter(std::shared_ptr<PrintExample>& pe) {} | ^~~~~~ /home/et/gtsam-project-matlab-main/example/PrintExamples.h:57:26: error: ‘shared_ptr’ is not a member of ‘std’ 57 | void consumePrinter(std::shared_ptr<PrintExample>& pe) {}

also, it doesn't appear in the readme (and I still haven't confirmed), but I changed the "WRAP_TOOLBOX_INSTALL_PATH" to control where the matlab 'toolbox' is generated, can you please confirm it is ok?

from gtsam.

@etamarlu updated to handle the error message. It's a C++11 standards issue.

Yes, WRAP_TOOLBOX_INSTALL_PATH is the correct variable to set.

same still

re-downloaded everything and started from scratch, yet..

Same compilation error? Can you please paste the output you're seeing over here?

from gtsam.

I'll also need information about your OS, compiler, Matlab version etc. I can help you but I need additional information.

from gtsam.

It looks like the same compilation error (below)

Enviroment information:
I am using vm with 64 bits ubuntu-22.04.
matlab 23a
CXX compiler identification is GNU 11.4.0

Thanks! I was able to reproduce the issue on my Ubuntu machine and have made all the fixes. Please re-download the latest version of the project template and you should be good to go.

from gtsam.

It works perfectly!

Thank you :)
