OLSRd exits on Redhat.

[sanjayjaiman]

I have the same issue as #89.

The suggestion in the above was to build all the plugins as that may be caused by missing plugins. For that use "make build_all". When I did that the make ended in an error "gps.h not found".
A simple "yum install libgps-dev" did not work.
I tried the following -

wget https://rpmfind.net/linux/fedora/linux/development/rawhide/Everything/aarch64/os/Packages/g/gpsd-devel-3.25-7.fc39.aarch64.rpm
sudo yum install gpsd-devel
That fixed "gps.h" not found
When I do "make build_all" but now I get

[CC] src/configuration.c
In file included from src/configuration.h:50,
from src/configuration.c:46:
src/gpsdclient.h:67:24: error: field ‘source’ has incomplete type

Please help

Adding the following did let me finish the "make build_all"

After the build finished, I expected OLSRd to not exit. But it still does:

sudo /usr/local/sbin/olsrd -f routing2.conf

if debug is disabled (set to level 0), olsrd detaches itself , if you do not want that, you need to enable debug.
you need to set at least DebugLevel 1 in your routing2.conf or enable debug like this:
sudo /usr/local/sbin/olsrd -d 1 -f routing2.conf

Thanks so much. That got me ahead a bit. Now I am getting -

. . . . . .

Running plugin_init function...

[sanjayjaiman]

In my config file I had the following -

LoadPlugin ""
{
PlParam "accept" "0.0.0.0"
}

I deleted that and OLSrd comes up.

Althogh OLSRd is running now on two containers I am having isssues with "olsrlinkview" in the Emane tutorial not showing the two nodes This may not be a question for this thread. But just in case someone has any input on that, it would be great.

[mathiashro]

Hi @sanjayjaiman , what exactly is your issue about "olsrlinkview"? (I'm not sure what your are refering to and did not found a reference at your emane-tutorial.

Can we close this issue since OLSRd is running as expected?
