Hello.
I am in the process of upgrading code to use boost 1.31.0 for MSVC6.5. During this process I happened upon minimum_category.hpp which contains "ETI workarounds". Now, it seems that the ETI workarounds cause the compilation to fail, with the error message: constant expression expected. Particularly, we are creating zip iterators to two STLPort vectors. In debug iterator mode, I get the following error. (minimum_category.hpp was modified a bit
Post the error you get with an unmodified minimum_category.hpp, please. It's hard to analyze when the line numbers are wrong.
but the problem is in the instantiation of boost::is_same<T1 or T2,int>). ^^^^^^^^
Huh? That's not valid regardless of any ETI workarounds.
If I remove the ETI "workarounds" the code compiles fine. So my question is what is ETI, what does the ETI workaround provide
