Windows: INSTALL deploy mode does not work
Building an application also needs the DLL stub library in $(OPCUA)/lib/$(T_A), not just the DLL in $(OPCUA)/bin/$(T_A).
(Careful: the stub is named differently between MSVC and MinGW.)
The application, on the other hand, should only install a copy of the DLL for distribution. The stub is not needed for running an application, just for building it.
We are trying to build it on windows (minGW) and we get : make[2]: *** No rule to make target '../opcua.dll', needed by '../../lib/windows-x64-mingw/opcua.dll'. Stop. You think it could be linked ? how can we choose between MSVC & MinGW ? our EPICS_HOST_ARCH is configured in a environnement variable
Which doesn't exist for Windows. (I don't even have a Windows license of the SDK.)
For Windows builds, you can use the UASDK evaluation bundle. (I'm testing with those.)
Long-term, I would recommend using the open62541 client. Free, open, and works on Windows.
In fact we don't know where to begin with windows ( linux is working but we want to test it on windows too). So you confirm that we have to download Source code (zip) and not BDIST ?
Start with reading the "EPICS on Windows" doc that explains the compilers and build options. https://docs.epics-controls.org/en/latest/getting-started/installation-windows.html
For that, you will have to download or check out the source code of the Device Support and build (open62541) or install (UASDK) the low-level client, correct.
