Having persuaded everything to compile in the 1.31.0 Regex library, it runs into another problem in building the .a archive libraries: tru64cxx65-Archive-action bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a /bin/sh: /bin/ar: arg list too long rm -f bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a ar r bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/c_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/c_regex_traits_common.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/cpp_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/cregex.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/fileiter.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/posix_api.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex_debug.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/regex_synch.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/w32_regex_traits.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/wide_posix_api.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/instances.o bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/winstances.o "bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release"/cxx_repository/* ...failed tru64cxx65-Archive-action bin/boost/libs/regex/build/libboost_regex.a/tru64cxx65/release/libboost_regex-tru-1_31.a... The problem is due to the number of instantiations in the template repository and the lengths of their names. There are 492 instantiations, and many of them have 90-character file names, which looks like the compiler's maximum allowed. I solved the problem in previous versions of boost by breaking up the build into separate steps. This was the way I modified the make file: AR:= ar -cq IIDIR:= $(LIBDIR)/cxx_repository $(DIRNAME)/lib$(LIBNAME).a : $(ALL_O) @echo "*** creating lib$(LIBNAME).a" rm -f $@ $(AR) $@ $^ @echo "*** adding template instantiations" $(AR) $@ $(IIDIR)/[_A-Z]* $(AR) $@ $(IIDIR)/[a-z]* It builds the library from just the object files and then adds the instantiations in two steps. (Apparently, adding all of them exceeded the same shell arg list limit.) How can I do something equivalent with bjam to build the library? -- Dick Hadsell 914-259-6320 Fax: 914-259-6499 Reply-to: hadsell@blueskystudios.com Blue Sky Studios http://www.blueskystudios.com 44 South Broadway, White Plains, NY 10601
