New issue 2626: invalid conversion from ‘const char*’ to ‘char* in cython based library https://bitbucket.org/pypy/pypy/issues/2626/invalid-conversion-from-const-char-to-char
Stuart Axon: Trying out pyimgui, a cython based binding to imgui, I found a couple of compile errors with pypy. https://github.com/swistakm/pyimgui This seems to be in unicode 16 decode functions and all complaining about "invalid conversion from ‘const char*’ to ‘char*" ``` python setup.py install Compiling imgui/core.pyx because it changed.
