I believe I added the following to the makefile locally for newer versions of gcc:

  USR_CXXFLAGS += -fpermissive -Wno-narrowing -Wno-write-strings -Wno-unused-but-set-variable

Subject: problem compiling edm

I've a new pc on which I'm running Fedora release 25.  I'm using base 3.15.5.

I'm attempting to build edm, but whilst attempting to compile, I get:

make[2]: Entering directory

../cursor.cc:82:50: error: narrowing conversion of ‘224’ from ‘int’ to ‘char’ inside { } [-Wnarrowing] and many more lines of the same.

I can't find this problem in tech-talk, nor with a web search. Has anyone run into this problem and if so, how did you resolve it?
Many thanks,
Pierrick
