Hello,
yes qmake can be a plague.
you could download Mcproxy to another computer, where the qmake dependencies are not a problem and generate a Makefile with qmake and simply use this Makefile.
I tried it, after deleting line 251 from the Makefile, it worked on my computer.
I also attached the Makefile to this message.
Or, you could use this repository (
https://github.com/mcproxy/mcproxy/tree/OpenWRT/uClibc), there is already a Makefile attached.
Regards,
Sebastian
