RE: Mixtures and Compiling w/ the CMDs sudo ./waf configure --board=blue and sudo ./waf

Bug report

While Compiling and While Configuring

I think that w/out the iiod and the dependencies it needs, I found this out while using the cmd sudo ./waf configure --board=blue, the configuration is off. I typed that b/c the issues I found while using that cmd produced some odd results.

These results were listed as lttng-ust not found and libiio not found. Then, I went on to produce this cmd: sudo ./waf. This cmd was to compile on my BBBlue. It is an Open Source board that has a Linux Distro on it.

Anyway...while compiling I noticed two issues:

There was a lack of:

XML Validation Libraries

and this created a set of info. that stated that XML libraries will not be used.

This is a snippet of info. from the compilation. It has to do w/ the a .cpp file that could not compile corrrectly.

Here are my logs from journalctl -f.

P.S. After compilation tonight, I am going to add the iiod and esp. libiio as the dependency under my Linux Distro. I have tried different kernels and different images so far, mostly Stretch 4.9 and 4.14.

P.S. I am almost done compiling. I just thought since you and your people were in charge of this bug report, you needed to know what was happening to the software on a Debian Stretch Distro.

[magicrub]

What version of gcc are you running?

[silver2row]

Hello,

I am using:

gcc (Debian 6.3.0-18+deb9u1) 6.3.0 20170516

Hello Again Sir...

Please see here: https://pastebin.com/PZDLC68G. It is my terminal on PuTTY from the BBBlue. I cannot connect to the MP software yet for calibration.

I am close. i can feel it.
