Not compiling imported programs in lpcxpresso

I always get the following error when trying to compile programs for lpc1768 and lpc11u68.

Hi,

This is known issue and we are working on it. https://github.com/ARMmbed/mbed-os/issues/2448

A quick workaround is to use the mbed library Rev.121 and upward.

I hope this helps.

The LPCxpresso export is still broken. Looks like that if a project that uses mbed-rtos and EthernetInterface one can't downgrade mbed to Rev.121 (or maybe I'm missing somethig...), so it is basically not possible to export such project. Any news on the topic? I've read in the bug log that an eclipse export is mentioned, but I don't know how to do it.

Thanks

Any progress on that?
