Trying to build (or get my hands on) Firmware version 1.14.3

Hello,

I need the firmware version 1.14.3, however through QGRound control I can only flash the newest version if I am not mistaken. So two things really:
First: Does anybody by chance have the px4 file version 1.14.3 for a cube orange plus laying around?

Second:

I tried to build the firmware myself using the development environment, however I encountered problems. All the 15 versions build fine however 14 does not work…
I get some warnings and finally this Error:

[ 25%] Built target nuttx_c_build
gmake[1]: *** [Makefile:156: all] Error 2
make: *** [Makefile:227: cubepilot_cubeorangeplus_default] Error 2

Is this maybe a Problem with the gcc Version?

Any help is highly appreciated, Thanks!

@JHanseatic I was able to build this in my computer. You can download the firmware for cubepilot_cubeorangeplus_default from the link below.
