At present any test in Boost.Math that depends on Boost.Test fails for GCC prior to 4.5 because the build script for Boost.Test has:
<toolset>gcc:<cxxflags>-std=gnu++0x
Is this really required?
It looks wrong headed to me:
* We already have testers that test both C++03 and C++11 modes - so we don't need this to test C++11 support. * It's presence makes testing gcc in C++03 mode impossible if the library uses Boost.Test - so there may be C++03 breakages that we don't know about because of this. * As mentioned above, this is a hard error for GCC prior to 4.5, so those compilers can't be tested either.
Can this be safely removed?
I have experimenting regression that disappear when this line is commented. This line must be removed. Could I commit it?
Confirmed. As Gennadiy hasn't responded I've gone ahead and committed the change. John.
