Description: Trying to build an image with libmosquittopp included and keep running into this issue:

Package libmosquittopp is missing dependencies for the following libraries:
libmosquitto.so.1

This problem has been occurring me for quite some time, we've talked about it in IRC before but never found a fix. This happens after make dirclean. I usually work around it with this hack:

diff --git a/include/package-ipkg.mk b/include/package-ipkg.mk
index c374faa647..49feb97d4d 100644
--- a/include/package-ipkg.mk

                        echo "Package $(1) is missing dependencies for the following libraries:" >&2; \
                        cat "$(PKG_INFO_DIR)/$(1).missing" >&2; \

Mosquitto related symbols in config:

$ grep -i mosquitto .config
# CONFIG_PACKAGE_libmosquitto-nossl is not set
CONFIG_PACKAGE_libmosquitto-ssl=y
CONFIG_PACKAGE_libmosquittopp=y
# CONFIG_PACKAGE_mosquitto-client-nossl is not set

@stintel try https://github.com/openwrt/packages/pull/7772

Maybe the libmosquitto depends needs a +.

Or it's not being installed properly.

[karlp]

It can't be a + depends, because you can't autoselect the virtual package. I'll be back to work tomorrow and will be looking at this.

[karlp]

@stintel do you reallllly have mosquitto without ssl, but libmosquitto with ssl? I mean, I guess that should work, but was that the goal?

[karlp]

I can confirm the issue if you have mosquitto-ssl + libmosquitto-nossl, but it works if you have mosquitto-ssl+libmosquitto-ssl or mosquitto-nossl + libmosquitto-nossl.

I can only presume this is a build system problem with dependency tracking. I'm not sure what I can do about it really, and while it should be a legal build combination, it's not really a very useful build combination IMO?

[stintel]

Using libmosquitto-ssl for vallumd, which connects to a public MQTT broker with SSL, and running mosquitto-nossl internally, used by Domoticz and some sensor devices. I don't need SSL for that, and I usually select only what I need.

I can do mosquitto-ssl+libmosquitto-ssl as workaround for now, but would be nice if this can be fixed eventually.

[karlp]

Well, it's a build issue, not a mosquitto issue, so there's nothing else I can do about it right now. We could try making -ssl and -nossl variants for libmosquittopp too maybe? might help?

Well, it's a build issue, not a mosquitto issue, so there's nothing else I can do about it right now.

Where should it be reported then?
