Hi, I tried to build boost1.48 with stlport5.2.1 (linux). I noticed such problem:

libs/locale/src/posix/numeric.cpp:215: error: invalid conversion from `int' to `stlp_std::ctype_base::mask'

This is simple problem like this one:

enum Test {     value }

Test test; test|=value; //error is here

I could use -fpermissive, however I think it's very intrusive. If you know other solutions let me know please.

Best regards, Bogdan

Ok. It is a bug in Stlport library. C++03 17.3.2.1.2 Bitmask types defines operator |= on the mask values. And std::ctype_base::mask is defined as bitmask type (not only enum) - it should have overloads for these operators. If you want to fix this you can do following Change the line:    mask r=mask(); To    unsigned r=0; And at the end of the function Change    *m++ = r To    *m++ = static_cast<mask>(r); If it works you can make a patch with some ifdef for STLPort to workaround the problem. I'll commit it (with proper ifdef) Also what compiler do you use?   Artyom Beilis -------------- CppCMS - C++ Web Framework: http://cppcms.sf.net/ CppDB - C++ SQL Connectivity: http://cppcms.sf.net/sql/cppdb/>
