The standard was released in 1998, but I don't think that *any* C++ compilers are 100% conformant. The major players (includes gcc) are all striving to achieve conformance however, so each new release tends to reject code that used to compile under the older, less compliant version. >>lyx 1.3.4 does compile with g++ 2.95, so there is hope. > > *Bright red face*.

I have two questions of my own: * what platform are you compiling on? * what is the native compiler for this platform? Eg, on Fedora 1 the native compiler is g++ 3.3.2. I ask because if you use something other than the native c++ compiler then you'll have trouble linking against libraries of c++ code. In your case, linking to the XForms library you have nothing to worry about because XForms is written in C. If, however, you had tried to compile the Qt version of lyx then you would have experienced probelms at link time if the library and lyx were compiled with different compilers. Name mangling differs from one compiler to the next. Just things to be aware of. -- Angus
