I have a very simple regex program that will not compile on AIX using IBM's xlc++ compiler.
Here is the program: "/usr/local/include/boost/regex/v4/cregex.hpp", line 75.4: 1540-0063 (S) The text "0x001" is unexpected.
I believe this is a known problem: there is a fix in the works but you may have to wait a while: the problem occurs if you include the platforms native <regex.h> before including <boost/regex.hpp>, I believe in some modes IBM's compiler includes <regex.h> if you include nearly any platform header. You could try moving <boost/regex.hpp> to be the first include, if that doesn't fix it, it gets harder, because the "correct" fix is a complete restructuring of the Boost.Regex header structure. I believe that our AIX regression tests were passing for Boost.Regex so there is a set of compiler options that will also remove the problem, our regression tests are using something like: xlC -c -DNDEBUG -O3 -qstrict -qinline -qnotempinc -qfuncsect -qeh -qrtti source-file.cpp but I don't know which of those is important, Regards, John.
