Hi, good to see that boost.log is being formally reviewed! From what I read in the documentation so far, I am really looking forward to seeing the library included in boost. I sure want to do some tests, hoping to replace our current logging system, soon, but today I can only answer the following review item: - Did you try to use the library? With what compiler? Did you have any problems? Yes, I tried and failed to compile it. Details are below. Platform: Ubuntu 8.04, 64bit, g++ 4.2.4 Intel QuadCore 2.5GHz, 8GB Ram Compilation: ============ Sounds embarassing, but I failed to compile the library. I copied the folders boost, lib and doc from boost-log-RC4 to boost_1_42_0, called ./bootstrap.sh ./bjam -d+2 --build-dir=build --with-log --prefix=/my/install/path link=shared runtime-link=shared install All looked well until this point: gcc.compile.c++ build/boost/bin.v2/libs/log/build/gcc-4.2.4/release/threading-multi/filter_parser.o "g++" -ftemplate-depth-128 -O3 -finline-functions -Wno-inline -Wall -pthread -fPIC -fno-strict-aliasing -DBOOST_ALL_NO_LIB=1 -DBOOST_DATE_TIME_DYN_LINK=1 -DBOOST_FILESYSTEM_DYN_LINK=1 -DBOOST_LOG_DLL -DBOOST_LOG_SETUP_BUILDING_THE_LIB=1 -DBOOST_LOG_SETUP_DLL -DBOOST_LOG_USE_NATIVE_SYSLOG=1 -DBOOST_SYSTEM_DYN_LINK=1 -DBOOST_THREAD_POSIX -DBOOST_THREAD_USE_DLL=1 -DDATE_TIME_INLINE -DNDEBUG -I"." -c -o "build/boost/bin.v2/libs/log/build/gcc-4.2.4/release/threading-multi/filter_parser.o" "libs/log/src/filter_parser.cpp" The process cc1plus was running about 20 minutes (100%CPU, moderate RAM usage) before anything else happened. Then, after lots and lots of very long error messages, it continues like this: ...skipped <pbuild/boost/bin.v2/libs/log/build/gcc-4.2.4/release/threading-multi>libboost_log.so.1.42.0 for lack of <pbuild/boost/bin.v2/libs/log/build/gcc-4.2.4/release/threading-multi>attribute_set.o... Hmm. Not sure how to proceed. Should I send the whole bunch of error messages to the list as an attachment? Regards, Roland
