Your compiler is complaining about an overly long string. This will probably fix it... In the file binary.tm, find something that looks like the following text: :Evaluate: resolveExistingFilename[s_String]:=Module[{first=First[Characters[s]],drive,os,fileinfo,thefile}, Switch[os=$OperatingSystem, "Unix", (* a whole bunch of stuff here *), "MacOS", (* a whole bunch of stuff here *), "Windows"|"WINDOWS"|"WindowsNT", (*a whole bunch of stuff here *), _, (* a whole bunch of stuff here *)]] This is being turned into a C string by 'mprep', and apparently it's too long for your compiler to swallow. We can make it simpler by just splitting out the stuff that's irrelevant for Solaris: :Evaluate: resolveExistingFilename[s_String]:=Module[{first=First[Characters[s]],drive,os,fileinfo,thefile}, Switch[os=$OperatingSystem, "Unix", (* a whole bunch of stuff here *), _, (* a whole bunch of stuff here *)]] which is to say, just delete all of the lines from the line beginning with "MacOS" to the line immediately preceding the one beginning with '_'. Or, you could rewrite your code in terms of Experimental`BinaryImport[] and Experimental`BinaryExport[], which is somewhat faster than FastBinaryFiles these days.
