+### On Solaris:
+
+The default Solaris linker can't be used, you have to install GNU ld, then run cmake manually with the path to your copy of GNU ld:
+
+        mkdir -p build/release
+        cd build/release
+        cmake -DCMAKE_LINKER=/path/to/ld -D CMAKE_BUILD_TYPE=Release ../..
+        cd ../..
+
+Then you can run make as usual.
