A new update of GLSL Hacker is ready.
Download for Windows 64, Linux 64, OSX and Raspberry Pi here:
On Arch Linux the plugin_gxl_python_27_x64.so fails because I don't have a libpython2.7.so.1, only libpython2.7.so.1.0 and libpython2.7.so
2015:08:26@15:29:28(0000000012) <!> Python 2.7 installation not found: unable to load Python core library (libpython2.7.so.1).
2015:08:26@15:29:28(0000000013) <!> Unable to load plugin plugin_gxl_python_27_x64.so
I should link the Python plugin with something that is present on every linux distro like libpython2.7.so. You can still try to copy the Python shared objects in the GLSL Hacker plugin dir and rename one of them in libpython2.7.so.1. That should work...
I will look at this issue for the next Linux update of GLSL Hacker.
