Hello, I am currently developing a cable driver for newer J-Links based on libjaylink, because the old driver doesn't work with newer V11 J-Links. The driver itself seems to kind of work as boundary scans do work. SVF replay is still kind of buggy, but the driver still is a WIP.
However, whilst trying to get libjaylink detection into the autoconf
scripts, I have a weird error:
> checking for LIBJAYLINK... yes
> checking for a Python interpreter with version >= 2.5... python
> checking for python... /usr/bin/python
> checking for python version... 3.8
> checking for python platform... linux

> ./configure: line 17966: syntax error near unexpected token `('
> ./configure: line 17966: ` as_echo_body='eval expr "X$1" : "X\\(.*\\)"''
This only happens when my custom stuff in configure.ac is present.
I don't have any clue what the problem might be. I tried to copy the
stuff from the libusb detection. I have not used autoconf at all, so I'm
kind of stuck right now.
Does anyone have a hint?
My code currently is at
https://github.com/boomer41/urjtag/tree/cable/jaylink
My configure.ac stuff starts at line 362.
If you have any critique on the code, please let me know too!
I haven't done anything with C in a while, so any feedback is
appreciated! :)
Thanks
Stephan
