Dear all, I tried to compile Rosetta for rosetta_refinement, on Mac OX10.10. I run " /rosetta_2014.22.56873_bundle/main/source] user% sudo scons.py But it was in failure, showing the following message: g++-4.2 -o build/external/debug/macos/14.0/64/x86/gcc/4.2/default/dbio/cppdb/atomic_counter.os -c -isystem external/boost_1_55_0/ -isystem external/include/ -isystem external/dbio/ -pipe -ffor-scope -Wall -Wextra -pedantic -Werror -Wno-long-long -Wno-strict-aliasing -m64 -march=nocona -mtune=generic -O0 -g -ggdb -ffloat-store -fPIC -DBOOST_ERROR_CODE_HEADER_ONLY -DBOOST_SYSTEM_NO_DEPRECATED -DCPPDB_EXPORTS -DCPPDB_LIBRARY_SUFFIX=\".dylib\" -DCPPDB_LIBRARY_PREFIX=\"lib\" -DCPPDB_DISABLE_SHARED_OBJECT_LOADING -DCPPDB_DISABLE_THREAD_SAFETY -DCPPDB_SOVERSION=\"0\" -DCPPDB_MAJOR=0 -DCPPDB_MINOR=3 -DCPPDB_PATCH=0 -DCPPDB_VERSION=\"0.3.0\" -DCPPDB_WITH_SQLITE3 -Ibuild/external/debug/macos/14.0/64/x86/gcc/4.2/default/dbio/sqlite3 -Iexternal/dbio/sqlite3 -Iexternal/boost_1_55_0 -Iexternal/dbio -I/usr/include -I/usr/local/include external/dbio/cppdb/atomic_counter.cpp sh: g++-4.2: command not found scons: *** [build/external/debug/macos/14.0/64/x86/gcc/4.2/default/dbio/cppdb/atomic_counter.os] Error 127 scons: building terminated because of errors. How can I resolve that? Best regards, H. Miyatake
