I try to write a simple plugin with gimpfu in python and I tried following those instructions.
1.2. Installation Gimp-python consists of a Python module written in C and some native python support modules. You can build pygimp with the commands: ./configure make make install This will build and install gimpmodule and its supporting modules, and install the sample plugins in gimp's plugin directory.
Where do I have to execute those commands?
I tried adding my script to the plugins folder but it seems like there is no python module called gimpfu. I believe I have to enable or install it in some way, but I can't find a solutio to do it.
EDIT: It seems like gimpfu is availible in the gimpfy-console insode gimp. It just doesn't seem to be availible for my plugin scripts.
No need to install anything. In the Windows versions Python support is built-in, and the gimpfu import is available when your code is executed by Gimp.
If you don't see the plugin in the menu it is likely a syntax error that doesn't let it run its registration code. See here for some debugging techniques.
However, since you mention PyCharm, you may have another Python interpreter installed and this makes things complicated because there can be conflicts depending on order of installation (and remember, Gimp uses Python 2.7)
Now it all depends if you are really doing a plugin (called from the Gimp menu) or a batch (where Gimp is called from a shell script), which is somewhat different. If you are writing a batch, see this answer for an example.
