It looks like the error comes from Line 64 of SnappyCompressor.c. I've tried to 
debug it, but I couldn't really determine why the code wasn't working.

Does anybody have any idea on why the error is generated?

fyi, "\u2019" is an apostrophe ('). Copy-and-paste was done improperly.

I experiance something similar (which also had to do with the resulting value 
of HADOOP_SNAPPY_LIBRARY determined in the "configure" script - that is, a 
custom configure function defined in acinclude.m4). If the available ways of 
resolving the value of the (snappy) library file doesnt work out, the configure 
phase dont fail directly. Instead some humbug value of the 
HADOOP_SNAPPY_LIBRARY is assigned and the compilation fails instead. Im a total 
gcc noob, so bear with my layman explaination.

...like for me, i clearly have the libsnappy files in /usr/local/lib, but the 
objdump  and ldd tools doesnt list it as a dependency after compiling/linking 
conftest.c with "snappy" as a dependency. Id expect you can hardcode 
"libsnapp.so" as the result of that custom function.
