I have some doubts about the procedure. In order to check the flags that must be defined, should I run the
bjam config_info config_test toolset=gcc-4.4.0 cxxflags="-std=c++0x bjam config_info config_test toolset=gcc-4.5.0 cxxflags="-std=c++0x bjam config_info config_test toolset=gcc-4.6.0 cxxflags="-std=c++0x
and compare the outputs?
Hi again, unfortunately I don't reach to get the config_info for my installed gcc-4.4. I get the following error \boost\trunk\libs\config\test> bjam -a config_info toolset=gcc cxxflags="-std=c++0x" > gcc440x.log In file included from c:\cygwin\gcc-4.4.0\bin\../lib/gcc/i386-pc-mingw32/4.4.0/../../../../include/c++/4.4.0/bits/postypes.h:42, from c:\cygwin\gcc-4.4.0\bin\../lib/gcc/i386-pc-mingw32/4.4.0/../../../../include/c++/4.4.0/iosfwd:42, from c:\cygwin\gcc-4.4.0\bin\../lib/gcc/i386-pc-mingw32/4.4.0/../../../../include/c++/4.4.0/ios:39, from c:\cygwin\gcc-4.4.0\bin\../lib/gcc/i386-pc-mingw32/4.4.0/../../../../include/c++/4.4.0/ostream:40, from c:\cygwin\gcc-4.4.0\bin\../lib/gcc/i386-pc-mingw32/4.4.0/../../../../include/c++/4.4.0/iostream:40, from config_info.cpp:19: c:\cygwin\gcc-4.4.0\bin\../lib/gcc/i386-pc-mingw32/4.4.0/../../../../include/c++/4.4.0/cwchar:159: error: '::swprintf' has not been declared c:\cygwin\gcc-4.4.0\bin\../lib/gcc/i386-pc-mingw32/4.4.0/../../../../include/c++/4.4.0/cwchar:166: error: '::vswprintf' has not been declared "g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -g -std=c++0x -DBOOST_ALL_NO_LIB=1 -I"..\..\.." -c -o "..\..\..\bin.v2\libs\config\test\config_info.test\gcc-mingw-4.4.0\debug\config_info.o" "config_info.cpp" I gues I have a problem with wide charracters on my config :( Surprisingly the outputs for 4.5 and 4.6 are the same. See attached files. There is a common line BOOST_NO_CONSTEXPR [no value] I guess this means that BOOST_NO_CONSTEXPR is defined with no value. But when I run the following with gcc4.5.0 or gcc 4.6.0 \boost\trunk\libs\config\test\all> bjam -a BOOST_NO_CONSTEXPR toolset=gcc cxxflags="-std=c++0x" > gcc460x.log I get the following logs gcc.compile.c++ ..\..\..\..\bin.v2\libs\config\test\all\no_constexpr_fail.test\gcc-mingw-4.5.0\debug\threading-multi\no_constexpr_fail.o In file included from ..\no_constexpr_fail.cpp:28:0: ..\/boost_no_constexpr.ipp: In function 'int boost_no_constexpr::test()': ..\/boost_no_constexpr.ipp:19:7: warning: unused variable 'i' "g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -g -mthreads -std=c++0x -DBOOST_ALL_NO_LIB=1 -I"..\..\..\.." -c -o "..\..\..\..\bin.v2\libs\config\test\all\no_constexpr_fail.test\gcc-mingw-4.5.0\debug\threading-multi\no_constexpr_fail.o" "..\no_constexpr_fail.cpp" ...failed gcc.compile.c++ ..\..\..\..\bin.v2\libs\config\test\all\no_constexpr_fail.test\gcc-mingw-4.5.0\debug\threading-multi\no_constexpr_fail.o... or gcc.compile.c++ ..\..\..\..\bin.v2\libs\config\test\all\no_constexpr_fail.test\gcc-mingw-4.6.0\debug\threading-multi\no_constexpr_fail.o In file included from ..\no_constexpr_fail.cpp:28:0: ..\/boost_no_constexpr.ipp: In function 'int boost_no_constexpr::test()': ..\/boost_no_constexpr.ipp:19:7: warning: unused variable 'i' [-Wunused-variable] "g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -g -mthreads -std=c++0x -DBOOST_ALL_NO_LIB=1 -I"..\..\..\.." -c -o "..\..\..\..\bin.v2\libs\config\test\all\no_constexpr_fail.test\gcc-mingw-4.6.0\debug\threading-multi\no_constexpr_fail.o" "..\no_constexpr_fail.cpp" ...failed gcc.compile.c++ ..\..\..\..\bin.v2\libs\config\test\all\no_constexpr_fail.test\gcc-mingw-4.6.0\debug\threading-multi\no_constexpr_fail.o... These log let me think that constexpr is provided. How these reports can be interpreted? BTW I see also BOOST_NO_0X_HDR_FUTURE [no value] But there is no such <future> file. So I think this check should be removed. Best, Vicente P.S I have taken the care to check the gcc version before running each test :) gcc (GCC) 4.4.0 Copyright (C) 2009 Free Software Foundation, Inc.
