Hello everyone,
I’m trying to update the cross-compiling Vagrant VM setup that can be found here for OF 0.10 and Stretch/arm6 and running into a weird problem.
I’m using the latest build_cross_gcc.sh script from jvcleave and have followed a few other guides, including this one:https://forum.openframeworks.cc/t/cross-compile-of-0-10-for-raspberry-pi-armv6-guide/31733
I can get through all the steps and am able to compile a simple test c++ code but when trying to compile an OF example, I get the following error
detected cross compiling 1

To me, that looks like the compiler somehow is compiling project as C instead of C++, but the compiler is correct (/opt/cross/bin/arm-linux-gnueabihf-g++) and cross-compilation is detected. I’ve tried poking around OF makefile and various config files for the make, but no luck so far.
Anyone see this before? any ideas?
P.S. My setup can be found here https://github.com/eshkrab/rpi-build-and-boot
