RDK problems

[Sebastian Meisner]

Hi!

I just cloned a fresh repo of the "develop" branch from
https://www.github.de/reconos/reconos.git.

I tried to build the hardware for the sortdemo using the reconos development
kit (rdk) however, it fails at compiling the HLS version of the sortdemo
thread (see [1] at end of mail). It seems like the rdk tries to feed the
unprocessed template files to Vivado HLS.

Any ideas how to solves this?


Kind regards
Sebastian

Hi Sebastian,

you are right that the files are not processed correctly by the RDK. The problem is, that you are calling rdk without the LANG environment variable set correctly to an UTF-8 encoding (e.g. en_US.utf-8). Leaving it empty causes python to open the files with plain ASCII encoding instead of UTF-8. This fails for some of the files using non-ASCII characters. Unfortunately, no errors are printed but the files are simply skipped during pre-processing.

Is there any reason for setting the LANG environment variable before calling rdk? I think you do not need to worry about it (on Linux I would suppose that it is already set to somrthing with UTF-8). I also tested it on my system and it also breaks with LANG="" but works fine without it.

Yours,
Christoph

Hi Christoph!

Thanks a lot! With LANG="de_DE.UTF-8" it works now. I've been setting the LANG
Variable, because i got another error when not setting it. After several
generations of ISE tools on my Ubuntu machine and several work arounds to get
everything working my environment seems to be messed up a bit...


Cheers,
Sebastian
