Errors running "make camotics" during firmware build

[MColeman0102]

Hi, I was following the development.md and I'm having trouble with "make camotics". Everything seems fine up until this point: scons: lib/libcbang-boost.a' is up to date. scons:lib/libyaml.a' is up to date. build_function(["build/build_info.cpp"], []) [Errno 2] No such file or directory [Errno 2] No such file or directory scons: `lib/libcbang.a' is up to date. scons: done building targets.

• export CBANG_HOME=/mnt/host/cbang
• CBANG_HOME=/mnt/host/cbang
• scons -C camotics build/camotics.so with_gui=0 scons: Entering directory `/mnt/host/camotics' scons: Reading SConscript files ... IOError: [Errno 2] No such file or directory: 'build/version.txt': File "/mnt/host/camotics/SConstruct", line 10: with open('build/version.txt', 'w') as f: f.write(version)
• cleanup
• umount /home/mark/bbctrl-firmware/rpi-root/dev/pts /home/mark/bbctrl-firmware/rpi-root/dev /home/mark/bbctrl-firmware/rpi-root/sys /home/mark/bbctrl-firmware/rpi-root/proc /home/mark/bbctrl-firmware/rpi-root/boot /home/mark/bbctrl-firmware/rpi-root/mnt/host /home/mark/bbctrl-firmware/rpi-root/

It looks like the camotics dev image might be missing the version.txt file for some reason.

Thanks! Mark

I think the problem is that the build directory is missing. Try creating that first.

Hey, Yes the build directory was missing from the camotics_dev.img file. I mounted it, created the build folder and closed it. The build proceeds but now I'm receiving this:

Exception: Chakra or V8 support is required, please rebuild C!. You may need to set CHAKRA_CORE_HOME or V8_HOME from /mnt/host/camotics/SConstruct line 85:

I'll dig into that and see what I come up with.
