OPC UA with freeRTOS LWIP [message #1859010] Fri, 05 May 2023 23:06 Go to next message

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

Hi Alois Zoitl,
Thanks for reply. I found that:
https://github.com/Pro/open62541-esp32
I will examine.

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.
