I am having trouble with regex on an Alpha-Dec with Compaq's compiler 6.3.

I've got regex to compile with generic.mak as follows:

CXX="cxx" CXXFLAGS="-inline-none" -D__USE_STD_IOSTREAM -DBOOST_REGEX_NO_EXTERNAL_TEMPLATES" LINKER="cxx" gnumake generic.mak

but then it comes to the link step an error occures:

ld: Unresolved: main

wierd, do compaq shared libs require a main?

Nevertheless, boost_regex.so is being build, but when I try to link an application with boost_regex.so I do get loads of errors concerning the C++ standard library:

ld (prelink): /usr/lib/cmplrs/cxx/V6.3-008/libcxxstd.a(cxxl_std_init.o): std::cout: multiply defined Warning: std::basic_string::npos defined as GLOBAL RCONST but is defined in a shared lib as a GLOBAL OBJECT Warning: std::basic_string, std::allocator >::npos defined as GLOBAL RCONST but is defined in a shared lib as a GLOBAL OBJECT Warning: std::locale::collate defined as GLOBAL RCONST but is defined in a shared lib as a GLOBAL OBJECT Warning: std::locale::ctype defined as GLOBAL RCONST but is defined in a shared lib as a GLOBAL OBJECT Warning: std::locale::monetary defined as GLOBAL RCONST but is defined in a shared lib as a GLOBAL OBJECT Warning: std::locale::numeric defined as GLOBAL RCONST but is defined in a shared lib as a GLOBAL OBJECT

Looks like the std lib deffinitions are being duplicated in the regex .so, there may be some define you can set to suppress this, but otherwise, can you build as a static library (either use bjam or else just compile all the source files and put them in a shared lib using your usual build tool - there is nothing special going on here).

Did you try using Boost.Build? I have used it for Boost.Python stuff on Tru64 with great success. -- Dave Abrahams Boost Consulting www.boost-consulting.com
