[solved] Building on Nvidia Jetson Nano

Ubuntu 18.04 LTS, this is the image that Nvidia puts up on the website.

Basically, I followed the build instructions, and used cmake_arm.sh ./build to set up build as my build directory. When I attempted to make, I received a lot of errors that broke down to this file:

The errors resulted from this line:
#define WRAP_OBJ_LAST(name) (::gw::id(name).TMPL ol< name >())

Right above that there’s a note about using the template keyword. Here’s your hint! It should ultimately be:
#define TMPL template

My GCC is:
gcc (Ubuntu/Linaro 7.5.0-3ubuntu1~18.04) 7.5.0

Now everything is working great. I didn’t find any reference to this while searching for an answer, so I hope this helps someone.

What did you do exactly? Did you edit the wrap16.h file?

Yes, I edited wrap16.h. You’ll see some conditional compiles near the end that define TMPL based on your GCC version. I just commented out all of that and just made it:

#define TMPL template

^ that is one of the options, but it only decides up to GCC 5 or so. If you’re inclined you could probably just fix the conditional compile to include this for > 5.

In the master branch we have it corrected already.
