Hi I'm trying to track down a very nasty stack corruption bug in my release code and therefore I would like to enabled the Visual C++ RTCs option to enable runtime stack checks in my release build, however when I try to do this I get an "Incompatible build options" error from the boost libraries. Specifically I get this from boosts AutoLink.hpp: #if defined(__MSVC_RUNTIME_CHECKS) && !defined(_DEBUG) # pragma message("Using the /RTC option without specifying a debug runtime will lead to linker errors") # pragma message("Hint: go to the code generation options and switch to one of the debugging runtimes") # error "Incompatible build options" #endif It seems to be suggesting that in order to use /RTC I need to do a Debug build, buts that's exactly what I don't want to do... I need to enable Runtime Checks in the Release build! Is there any way to get this to work in a release build that uses boost? Does anyone know the details of the incompatibility? Surely /RTC doesn't require all linked in DLLs also to be compiled with /RTC? Thanks in advance. Ben This email is from Verint Systems UK Ltd and is confidential.
