OSerror

[Peter Vince]

I'm using "glumpy" to develop GL applications using python with Spyder as an IDE. Immediately I ran into this problem with the incomprehensible message -

-------

OSError: dlopen(/usr/local/lib/libfreetype.dylib, 0x0006): tried: '/usr/local/lib/libfreetype.dylib' (code signature in <4CBC5B96-18F2-3BA6-B6A8-A0051B19C0EA> '/usr/local/Cellar/freetype/2.12.1/lib/libfreetype.6.dylib' not valid for use in process: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.), '/usr/local/Cellar/freetype/2.12.1/lib/libfreetype.6.dylib' (code signature in <4CBC5B96-18F2-3BA6-B6A8-A0051B19C0EA> '/usr/local/Cellar/freetype/2.12.1/lib/libfreetype.6.dylib' not valid for use in process: mapped file has no cdhash, completely unsigned? Code has to be at least ad-hoc signed.)

--------

with a simple program -

--------

from glumpy import app

window = app.Window()

@window.event

def on_draw(dt):

window.clear()

app.run()

------------

This runs without error in ipython running in bourne shell.

I suspect this lies in the PATH environment variable for which you have

window that allows viewing of the contents but no editing.

Any thoughts would be welcome.
