Boost::Statechart: Shadow Variables Cause Warnings/Errors When Headers Are Not in System Path
| Reported by: | Owned by: | Andreas Huber | |

Description
I've recently added Boost 1.39.0 to an Xcode 3.1.3 project with the following warnings enabled in GCC/G++ 4.0.1:
-Werror -Wreturn-type -Wunused-function -Wunused-label -Wunused-variable -Wshadow
Unfortunately, when boost is not installed in a "system" path--as is the case here--unused and shadow variable warnings cause the build to fail when warnings are treated as errors.
The included header is:
boost/statechart/result.hpp
To test and fix, I isolated with:
printf "#include <${BoostHeader}>\nint main(void) { return 0; }" | /Developer/usr/bin/gcc-4.0 -x c++ -Wall -Wshadow -Werror -o test -I${BoostRoot}/boost/include -
The patch to address this is attached.
Because this problem seems to come up frequently in all Boost subsystems, perhaps there is a way -Wshadow and -Wall can be forced for all unit tests?
