Cannot find -lstdc++_nano, -lg_nano, -lg_nano [SOLVED]

Troubleshooting
1

I'm trying to compile the Photon firmware locally and I'm having trouble setting up my environment. I followed the steps in the Github repo's gettingstarted.md. Since then I've done a fair bit of troubleshooting with no luck. I've done a lot of digging and it seems like Issue #60 could be related to my problem.

I'm on Ubuntu 14.04 LTS.

When I run sudo make PLATFORM=photon from my firmware/main directory, I get the following output:

/home/brian/bin/gcc-arm-embedded/gcc-arm-none-eabi-4_8-2014q2/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld: cannot find -lstdc++_nano

For the record here is the output when I run arm-none-eabi-gcc -v

Using built-in specs.

Any ideas?

This is caused by using an older compiler (the 4.8.x line) which used a different suffix for the runtime libraries (_s instead of _nano). A fix for this has just been pushed to latest and develop branches.

Please pull down the branch - the problem should be resolved. :smile:

Thanks for the quick reply! I’ll give this a try tonight.

This works now. Thanks for the help @mdma!
