I'm porting some g++ code to MSVC, and I'm trying to use the Boost.Wave driver executable as a preprocessor instead of Visual Studio's. Boost 1.54.0. I'm generally successful, but I'm having trouble with macros like these: #define LOG(msg, ...) whatever Usage examples: LOG("Hello world!"); LOG("Hello and print out some variables", foo, bar); Both g++ and MSVC have custom extensions that make these examples work, but Wave is pretty strict and follows the standard to the letter, so gives the error message "not enough arguments for macro LOG" for the first example. I know it's possible to rewrite each macro like this in a standard- compliant way, but it's a lot of work and gets complicated if I want recursive macro invocation. Is it possible to enable this behaviour in wave somehow? Do I need to compile Wave Driver with a specific option? I searched through the docs and tried looking at the code, but I can't find anything.

As you said, Wave is very strict - and this is by design. Thus there is no compile time option enabling this feature. I'd need to have a closer look to decide how much work it would be to optionally enable this (non-standard) behavior. Regards Hartmut --------------- http://boost-spirit.com http://stellar.cct.lsu.edu
