m8c the answer is Abort

[decadenet]

Hello, m8c seems not working. After running m8c the response is Abort.

pi@raspberrypi:~ $ m8c /dev/ttyAMC0 INFO: Looking for USB serial devices. INFO: Found M8 in /dev/ttyACM0. INFO: Opening port. Abandon pi@raspberrypi:~ $

Your user probably does not have the proper rights to use the port, or there is some other problem with libserialport. Please try running the program with 'LIBSERIALPORT_DEBUG=1 m8c' and paste the full log here.

I'm having the same issue so I hope it's ok if I leave my own comment on this issue. I tried runing with sudo and mine failed also so I'm not sure it's a permissions issue. Here's the log (running on Linux Mint 20.2):

[2]    1870809 abort      sudo LIBSERIALPORT_DEBUG=1 ./m8c

[defensem3ch]

OK I talked to jefftheworld and apparently the issue is that the libserialport shipped with my distro has a bug. He advised compiling those libs and rebuilding m8c, which I will do

[defensem3ch]

OK I followed the instructions in https://github.com/laamaa/m8c/issues/20 but am now getting this error:

❯ ./m8c
./m8c: error while loading shared libraries: libserialport.so.0: cannot open shared object file: No such file or directory

[defensem3ch]

OK I got it. Just had to run

❯ sudo ln -s /usr/local/lib/libserialport.so.0.1.0 /usr/lib/libserialport.so.0.1.0
❯ sudo ln -s /usr/local/lib/libserialport.so.0 /usr/lib/libserialport.so.0
❯ ./m8c

and then it worked!

[laamaa]

Glad to hear you got it to work. Doing make clean && make in m8c code directory after installing the new lib should theoretically take care of referencing the correct files, but good that you found a workaround anyway. :)

[laamaa]

@decadenet Could you please try the same thing as @defensem3ch did and see if that solves the issue.

[JeffAlyanak]

@laamaa Not all distros are configured to load libraries from /usr/local/lib/ where the libserialport makefile puts them.

[laamaa]

I'm closing this issue as it is very likely a duplicate of https://github.com/laamaa/m8c/issues/20.

@decadenet please comment if the problem persists even after building libserialport from sources.
