Re: [mosquitto-dev] error adding symbols: file format not recognized

[Antonio English <antonio.english@xxxxxxxxxxxx>]

Hello, thank you for your response. The locations are all on my linux virtual machine. I installed the mosquito library using vcpkg. I am assuming that the libmosquitto_static.a library needs to be the same architecture as the the project that I’m linking the mosquito library to?

The image below is the SDK toolchain for the the Uzone project that I’m trying to add the mosquito library to.

Hi Antonio,

 

This sounds like the libmosquitto_static.a you are trying to use does not match your operating system or CPU architecture. The location seems to be some shared folder between a host an a virtual machine so most likely the library is meant for a different type of machine/architecture.

 

Best

Norbert
