Cannot compile on Linux Mint 19: invalid conversion from ‘char**’ to ‘void**’ #20

Closed Cat5TV closed 5 years ago

Well, I've gotten this far, but am stumped.

During the make process, it errors out with the following:

......

viacamcontroller.cpp: In member function ‘CCamera* CViacamController::SetUpCamera()’:
viacamcontroller.cpp:233:70: error: invalid conversion from ‘char**’ to ‘void**’ [-fpermissive]

Thoughts?

My arm is killing me... I'd really like to get eViacam working :)

Thanks!

Got it working by installing the old version of wxWidgets (manually compiled 3.0). So it seems this issue occurs only on current versions of wxWidgets.

Here is the installer script I wrote based on my findings: https://github.com/Cat5TV/eviacam

I will be featuring eViacam (on Linux Mint 19) on Episode 607 of Category5 Technology TV, if anyone would be interested in seeing the installation process and product demo.

Thanks @Cat5TV. I've added a comment clarifying the situation and linking your script here: https://github.com/cmauri/eviacam/issues/14#issuecomment-491756387

Could we re-open this? It's not just a Mint issue; it also happens when compiling on Arch.

As it's an issue that is coming up with newer (but same major versions) of wxWidgets, a proper fix would be to address the issue in the code that's causing the compiler error. In any case, what's provided is a work-around, not a fix, and it would make more sense to leave this open until the root cause is addressed.
