Installing with pip shouldn't use SWIG, so it doesn't matter if it's installed or not. This is clearly a bug but I'm surprised I haven't encountered it on the computers I've been using. Maybe something to do with the default size of int on different systems. I haven't had a Mac since the days of MacOS 8.

Commit f174207 (released as v1.4.1) should fix this.

amirom commented 8 years ago

Hi Jim, Thank you so much for pushing that fix, unfortunately that didn't solve the issue. Since linux seems to be the key here, I decided to pull the trigger and dev on ubuntu. Again, appreciate your efforts, but it built magically well on this linux distro!

jim-easterbrook commented 8 years ago

It's odd that v1.4.1 didn't fix the problem, as it entirely removes the function that was upsetting the compiler. I would like python-gphoto2 to work on MacOS.

I'm sorry to revive a long untouched and closed issue but has there been any progress on this?

jim-easterbrook commented 6 years ago

I don't have MacOS so am not able to investigate the problem myself. What errors are you getting when trying to install the current version?
