[numeric/conversion] Possible bug in converter.hpp ?
Hello,
I'm trying to build openvrml 0.15.10 which uses the Boost library.
However, I get the following error message:
/usr/include/boost/numeric/conversion/detail/converter.hpp:233: error: expected unqualified-id before numeric constant
/usr/include/boost/numeric/conversion/detail/converter.hpp:238: error: type/value mismatch at argument 6 in template parameter list for 'template

It might well be a problem in converter.hpp but I can't see it with the information you are providing me since the error is triggered by the template parameters used in your specific case. In gcc, you get a sequence of "Instantiating from" messages that allow you to see the compilation path that leads to the failing template instantiation and the corresponding template parameters. Can you use that to isolate the problem into a small but complete program? TIA Fernando Cacciola

I didn't get any other error message that the ones that I posted in my first email. I have also noticed that if I comment out the declaration of 'None' (line 233) and replace 'None' by 'void' in line 238, then the compilation is successful. I don't know C++ so I'm not sure how appropriate this fix is. However, it implies that the problem is in the declaration of 'None' itself and that the following errors about line 238 are caused by this failed declarations. A cause of this problem could be that None is already defined in a standard X11 include file (/usr/X11R6/include/X11/X.h): #ifndef None #define None 0L /* universal null resource or null atom */ #endif That's all the information I can give now. Let me know if you need more information. Thanks. Eric Belanger
