Hi i am using boost 1.32 on the sun solaris. Machine: *SunOS etbf27 5.9 Generic_122300-13 sun4u sparc SUNW,Sun-Fire-V440* Compiler: *CC: Sun C++ 5.8 2005/10/13* And i am getting the following error when i use the tokenizer <> Error : "*/usr/include/boost/iterator/iterator_facade.hpp", line 837: Error: Could not find a match for boost::iterator_core_access::equal*" I googled and found out that its a bug in the boost 1_32_00 version of boost but could not find anything concrete except to upgrade to the next version. I cannot upgrade because 1_32 is already used in many parts of project and i have to go through a long chain of approval. Can you please provide me links to the workaround if there is one available. P.S : Its my first post ... Feel free to point out the mistakes i made in posting and i would be happy to correct them.
