Hello All, I am building boost 1.54 on a linux box and I am seeing the following error messages after the build: gcc.compile.c++ bin.v2/libs/wave/build/gcc-4.7/release/link-static/threading-multi/instantiate_re2c_lexer_str.o gcc.compile.c++ bin.v2/libs/wave/build/gcc-4.7/release/link-static/threading-multi/token_ids.o gcc.compile.c++ bin.v2/libs/wave/build/gcc-4.7/release/link-static/threading-multi/wave_config_constant.o common.mkdir bin.v2/libs/wave/build/gcc-4.7/release/link-static/threading-multi/cpplexer common.mkdir bin.v2/libs/wave/build/gcc-4.7/release/link-static/threading-multi/cpplexer/re2clex gcc.compile.c++ bin.v2/libs/wave/build/gcc-4.7/release/link-static/threading-multi/cpplexer/re2clex/aq.o gcc.compile.c++ bin.v2/libs/wave/build/gcc-4.7/release/link-static/threading-multi/cpplexer/re2clex/cpp_re.o gcc.archive bin.v2/libs/wave/build/gcc-4.7/release/link-static/threading-multi/libboost_wave.a common.copy /home/yadav/dev/cpp/boost_1.54/lib/libboost_wave.a ...failed updating 29 targets... ...updated 10797 targets... How can I know what these 29 targets have failed and how to go about getting a clean build? Thanks!
