That would be a compiler bug, please submit it such if you are able to, in the mean time I will patch a workaround into the source. [ Note - the reason it's a compiler bug, is that in the code: inline match_flags& operator&=(match_flags& m1, match_flags m2) { m1 = m1&m2; return m1; } The result of m1&m2 is type match_flags, and *not* int as the compiler suggests, because of the earlier defined operator: inline match_flags operator&(match_flags m1, match_flags m2) { return static_cast(static_castboost::int32_t(m1) & static_castboost::int32_t(m2)); } - end note ]

These are just a few. The rest of the errors occured for the same reasons in various files. (If you want those too - let me know).

Yes! I can't patch the source unless you give me all the available information. Incidently it might be easiest to work around this by including sunpro in the workaround above that reads: #if BOOST_WORKAROUND(BOOST_MSVC, <= 1200) || BOOST_WORKAROUND(__BORLANDC__, BOOST_TESTED_AT(0x564)) in match_flags.hpp

2. The aCC errors are (HP-IX): aCC -o generic/boost_regex/cpp_regex_traits.o -c -Aa -AA +O2 -I../../../ -O ../src/cpp_regex_traits.cpp Error 742: "../src/cpp_regex_traits.cpp", line 382 # Source type const char *& and target type char * in a const_cast can only differ in their qualifiers pmd->sbuf.pubsetbuf(const_cast(first), static_caststd::streamsize(last-first));

I mistakingly wrote dynamic_cast in the original post, but I meant const_cast. Sorry for the confusion.

Please notice that we had to add manually some flags to generic.mak (which is the makefile we used to build it on HP-IX). I'm aware of some example you gave in the html documentation about compiling with aCC - but we still had to change some flags. (I know these weren't formal settings and just an example).

Is there any chance that there will be a HP-IX-special makefile? It will make life much easier. :-)

If you want to provide one - I don't have access to that compiler.

3. I forgot to mension, that we managed to compile RegEX with SunOS C++ 5.5 both in 32 & 64 bits. There were no errors, BUT in 64 bits when we tried to run the rs/regress test - it failed (something which didn't happen in the 32-bits version). There was also a memory access violation, so even thought the compilation went just fine - apparently the library is not fully 64-bit compatible.

What can we do to overcome this problem?

OK a couple of data points: the library is passing all it's tests with IBM C++ on Itanium, so I would be surprised if this is 64-bit issue as such, it's more likely to be a compiler or platform specific issue. As I asked before what precisely is failing? What is the general protection fault? Where in the code does it occur (stack trace?) and so on. I'm going to need a lot more information before I can make any suggestions, and probably you're going to have to do some debugging as well... John.
