OPC UA with freeRTOS LWIP [message #1859010]

Hi,
I want to use opc ua in my freertos system(esp32s2). I compiled opc ua for posix there is no problem in there. But when I try to compile opc ua (git clone https://github.com/open62541/open62541.git --branch=v1.0 open62541) for freertos lwip with esp32s2 gcc compiler there is a lot of error.
Can I use libopen62541.so (built for posix) in my freertos system?
I think in order to use opc ua in freertos I must to compile with own compiler. Am I wrong ?

Best Regards.

Hi,

yes you need to compile all code and all libraries you would like to use with the compiler, libs and includes of your target system. I don't know if open6251 has been ported to freeRTOS. But I think this is the first thing you need to check. So I would suggest to ask the open62541 people about this.

Cheers,
Alois

Maybe for that you will need the upcoming 4diac FORTE release. You can find it in the freeze branch of 4diac FORTE's git repo.
