Build 4diac FORTE for Multiple Target on WSL

Meanwhile, this is for the Raspberry Pi 4B and Windows targets, although I have also done it for the Ubuntu 20.04 server.

I wrote it as personal blog content but you can asking related questions here.

UPDATE:
I decided to upgrade Ubuntu WSL from 22.04 LTS "Jammy Jellyfish" to 24.04 LTS "Noble Numbat" to use gcc-mingw-w64 and g++-mingw-w64 packages from Ubuntu distribution but had a problem with FORTE that compilation result did not run without any error message. In order for FORTE compilation results run successfully we have to change gcc and g++ thread model from default win32 to posix, do the following:

$ sudo update-alternatives --set x86_64-w64-mingw32-gcc /usr/bin/x86_64-w64-mingw32-gcc-posix
$ sudo update-alternatives --set x86_64-w64-mingw32-g++ /usr/bin/x86_64-w64-mingw32-g++-posix


UPDATE:
Upgrade to Ubuntu 24.04 make me feel stupid because the compilation result for Raspberry doesn't work anymore with an error message "/lib/aarch64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found" even though I compiled using gcc version 11. Incompatible libc version!

I suggest sticking with Ubuntu version 22.04 or switch to GNU toolchain from Arm but then requires an adjustments in compilation: change compiler from aarch64-linux-gnu-* to aarch64-none-linux-gnu-*

$ cd
$ wget -c https://armkeil.blob.core.windows.net/developer/Files/downloads/gnu/11.3.rel1/binrel/arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu.tar.xz
$ tar xvf arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu.tar.xz
$ export PATH=$HOME/arm-gnu-toolchain-11.3.rel1-x86_64-aarch64-none-linux-gnu/bin:$PATH


UPDATE:
Attached 2 patch to fix modbus build and com raw layer to fix MQTT data publishing/subscribing.

@Alois Zoitl Please check attached patch above. Sorry, I haven't used gerrit for a long time.

I somehow missed your patches. Sorry for that. According to the Eclipse development process I can only accept them if you sign the Eclipse Contributor agreement and provide them (currently) as Gerrit pushes. There is a very nice documentation by Jose what you need to do: https://eclipse.dev/4diac/en_help.php?helppage=html/development/contribute.html

However we are in the phase of moving all Eclipse 4diac repositories to github. Maybe a github pull request is more suitable for you. I hope to have that done for 4diac FORTE in the next 2-3 weeks.

Finally your documentation looks great. Would you be interested to write a guest news/blog post for the Eclipse 4diac Web-page? You can easily do this by submitting a github pull request to our web-page content git repo: https://github.com/eclipse-4diac/4diac-website

Sorry for the late response. A great news! Nothing wrong with gerrit but somehow too complicated. I want to write a content for 4diac FORTE project but my English is not that good :D

I found a bug in OPC UA client. There is no attempt to reconnect to the server if the connection is lost. Attached a patch to fix it but I'm not sure if it's a proper fix but always works for my situation.

I build a server application based on Open62541's CTT https://github.com/open62541/open62541-ctt, modified to load our own nodesets created using Siemens's SiOME - OPC UA Modeling Editor. I can connect to the server using my self signed certificate via Unified Automation UaExpert application but FORTE can only access the server using a username and password with securityPolicy=http://opcfoundation.org/UA/SecurityPolicy#None. Please confirm about FORTE's OPC UA with OpenSSL security support.

Looks like open62541 v1.3.9 isn't working correctly using openssl 3.x yet. Switch to mbedtls and immediately able to connect to the server using:
1. securityPolicy=http://opcfoundation.org/UA/SecurityPolicy#None and securityMode=1
2. securityPolicy=http://opcfoundation.org/UA/SecurityPolicy#Basic128Rsa15 and securityMode=2 or 3
3. securityPolicy=http://opcfoundation.org/UA/SecurityPolicy#Basic256 and securityMode=2 or 3
4. securityPolicy=http://opcfoundation.org/UA/SecurityPolicy#Basic256Sha256 and securityMode=2 or 3

I did use open62541 provided script to create the certificates. The certificate URI is "urn:unconfigured:application" which is the client default URI:
/usr/share/open62541/tools/certs/create_self-signed.py -u "urn:unconfigured:application" -c client

I have several in-service Siemens IOT2050 with Ubuntu Focal image, it's hard to upgrade without inferencing our system. FORTE develop branch need gcc version >= 11.3 but not found any toolchain that compatible to our IOT2050 GLIBC 2.31. Today, finally I manage to compile FORTE including libmodbus, mbedtls, paho mqtt, libopen62541, and libluajit using musl's libc from https://toolchains.bootlin.com/. Although experiencing a strange cmake problems to create a working fully static binary, finally FORTE develop branch bynk on one of our IOT2050 :D

Hi,

would you mind posting different discussion topics in different forum topics. This helps me and others to better keep track and later search for it.

We are on our journey to migrate the 4diac FORTE repo to github. Would you be able to provide PR requests there?

Anything that makes 4diac FORTE's open62541 and OPC UA usage more secure would be great. However I'm not an expert on that topic.

Sorry, I was just too excited :D

In my use case, a secure OPC UA is a must in our mixed Wide Area Network. I hope I can contribute to 4diac project via Github, I was waiting for it.

I totally get that. I'm also very happy that Eclipse 4diac serves your needs.

@Alois Zoitl Sir, attached a patch to support a toolchain with musl libc https://www.musl-libc.org/ from https://toolchains.bootlin.com/ I found musl libc use smaller memory footprint on Raspberry Pi 4B. I think musl is a good choice for embedded Linux target. I also attach a build scrip as a reference for our user to build FORTE for Linux x86_64, Windows x86_w64 (mingw_w64), Raspberry Pi aarch64, and aarch64 with musl libc that actually for Siemens IOT2050 target.
