Hi, I am having some major problems trying to compile EpicsQt source files to make custom plugins

 

My setup is a Windows 64 bit machine and I compile in 32 bits but I think the problem is using Qt5 which is 32 bit and telling me “%1 this is not a valid win32 plugin”

 

Setup:

64Bit machine, Windows7

Qt5

For Visual Studio I used the C++ libs:

VC 2012 and VC 2015. I ended up only using VC2012 libs to get as close to the Qt4 install as possible

Mingw32 bit

Strawberry Perl 32 bit

 

All compiled on the command line.

 

The version of EpicsQt is 3.1.0 simply because I found a working windows version of epicsqt on Sourceforge that I could trial and assumed that if the EpicsQt team could get that working so could I.  I have made some of my own libraries under this system but I get a strange “not valid win 32” error when try to open the QEPlugin.dll in designer 5.5. I am wondering if I am using something that is too new?

 

I compiled Epics Base and epicsqt with the win-x86-ming32. The only change I made was to comment out Timespec for EPICS base to get this to work with Mingw32 but base works and caget opens. VC2012 is also set to be 32 bits in this compile.

 

Now for EpicsQt:

3.1.0 compiles just fine. I used a program called “depends” to check QEPlugin.dll . It shares to the exact same x64 system libs that the working demo version uses and is an x32 lib like the working version. So, seeing as I have used 32bits everywhere, any idea why Qt5 should throw that error? Will EpicsQt not build for Qt5? I’m hoping that one of the Qt’ers out there has used a similar setup (Qt5, Visual Studio 2013 or 2015). I tried to install Qt4 in desperation but it is telling me that Mingw32 Is too new and may cause errors. I am wondering what should be the next step forward, as the Qt designer “not a valid win32 ” error is not much to go on.
