Re: [paho-dev] Paho MQTT C++ client sample
Yes. It will be fixed in the next update. The absolute path slipped by me last time. Dumb mistake.

Hi,

Could the user specific paths in the Makefile be removed anyway?

PAHO_C_LIB ?= /home/fmp/static/opensrc/mqtt/paho/org.eclipse.paho.mqtt.c

I don't believe this is appropriate and masks problems that "real"
users might have, just to make life a bit easier for one developer.

Cheers,

Roger

My current development branch is working. I can look to see if there is
something I did to fix this specific problem.

Hopefully a simple patch will fix this right now, then I can follow up with
my current version. That one should carry us until a formal, coordinated
release (1.1?)

Frank,

I don't think there have been any updates to the externals that should have
affected the C++ wrapper.  I hope I'd have told you otherwise :-)

I'll try building when I get home - none of my machines at work have a
recent enough version of gcc.

The Paho C++ library is a wrapper around the C library. The C library has
had a number of updates and improvements since the last C++ update. Perhaps
compatibility was broken between the versions. I will look and patch
accordingly.

Hi,

I've just tried to compile the samples of the Paho MQTT C++ client, but it
looks to me that the make file contains some hard coded references to other
projects:

After fixing the references make returns the following errors:
