[erlang-questions] IPC bus for Erlang?
Fri Apr 3 13:24:39 CEST 2009
Just two more things:
1. It appears on Mac OS X Leopard that it is needed to instruction the
wxerlang configure script to use the newly installed wxWidgets library, like
2. in wxerlang, "make install" fails with the following error:
olibrius:wx camille$ sudo make install
escript ./install.es @libdir@
escript: exception error: undefined function 'escript__install.io':format/2
in function 'escript__install.es__1238__757603__565159':main/1
in call from escript:run/2
in call from escript:start/1
in call from init:start_it/1
in call from init:start_em/1
make: *** [install] Error 127
Sorry, I am not proficient enough in escript to be able to fix that.
I am using Erlang OTP R13A.
