I'm still having a lot of issues with the latest Boost.Test not building: On Win32 with Intel's 11.1 and 12.1 compilers I see: ..\..\..\boost/test/impl/execution_monitor.ipp(104): error: invalid redeclaration of type name "_invalid_parameter_handler" (declared at line 228 of "C:\Program Files\Microsoft Visual Studio 10.0\VC\INCLUDE\stdlib.h") typedef void* _invalid_parameter_handler; And on Ubuntu Linux with gcc I see: gcc.compile.c++ /home/john/bin/boost/bin.v2/libs/test/build/gcc-4.4.3/debug/link-static/unit_test_main.o In file included from ../../../libs/test/src/unit_test_main.cpp:16: ../../../boost/test/impl/unit_test_main.ipp: In function 'int boost::unit_test::unit_test_main(boost::unit_test::test_suite* (*)(int, char**), int, char**)': ../../../boost/test/impl/unit_test_main.ipp:97: error: 'getchar' is not a member of 'std' "/usr/local/gcc/4.4.3/bin/g++" -ftemplate-depth-128 -O0 -fno-inline -Wall -pedantic -g -DBOOST_ALL_NO_LIB=1 -I"../../.." -c -o "/home/john/bin/boost/bin.v2/libs/test/build/gcc-4.4.3/debug/link-static/unit_test_main.o" "../../../libs/test/src/unit_test_main.cpp" Probably a missing <cstdio> include?
