Issue while compiling #2

Closed mcgurk94 closed 5 years ago

mcgurk94 commented 5 years ago

I've been consistently getting an error while trying to install with the setup file.

I'm currently running with Python 3.6 (32 bit) and compiling with visual studio 2019 - I've tried uninstalling and using an older version of VS (2015) but it spat out the same errors while compiling.

This might be entirely user error, but is there any guidance you could offer to help get this installed?

The symbols look decorated. Be certain you have the 32-bit PVCAM installed - 64 bit functions are not decorated by the compiler. No reason 32-bit should be a problem provided everything matches. In general we suggest using 64-bit PVCAM. Is there a requirement pushing you to use 32-bit?

Thanks, I'll see if I can make any progress with this when I'm back in the office.

There's no reason I can't move on to use the 64 bit version of pvcam if that's what you recommend; the lab replaced their prehistoric laptops fairly recently but kept most of the software the same, I can update them if required.

Just retried the install with your advice and it all went smoothly this time, thanks for your help
