Hi, I am trying to build the lastest boost release candidate (also tried the latest CVS version), and I am getting the below compiler error. I suppose, there is some problem with the wide character support, but I could not fix it. Perhaps someone on this list had similar problems and knows what to do? System Info: FreeBSD 5.3-STABLE, Compiler: (gcc -v) Using built-in specs. Configured with: FreeBSD/i386 system compiler Thread model: posix gcc version 3.4.2 [FreeBSD] 20040728 Let me know, if you need more info, or if I should ask somewhere else, and thanks in advance for your time.
