Trying to generate Murmur.php for the server component of Mumble (named Murmur (which is the only place I’ve ever encountered Ice)), slice2php gave the error:
/usr/share/slice/Murmur.ice:9: error: Can't open include file "Ice/SliceChecksumDict.ice" #include
1 error in preprocessor.
To fix this I had to run slice2php with a -I statement, to tell it where to find the SliceChecksumDict file (which you can locate using locate or find or the packages search):
slice2php -I/usr/share/Ice-3.4.2/slice /usr/share/slice/Murmur.ice
