Hello, I'm trying to build boost on our SGI Onyx4 and am running into some problems. I've tried looking up some documentation for configuring the build-system a bit better, but couldn't find much. I don't have the time to dig into it and find it out myself, especially since building boost isn't my ultimate goal for this exercise, so I'm hoping you can help me out here I'm getting (a lot of occurances of) three errors throughout the build: 1) the indicated type is incomplete std::basic_istream<charT> m_is; // stream for parsing numbers. Not sure about this one. Missing include somewhere or maybe SGIs STL is f00bar 2) The indicated enumeration value is out of "int" range. enum npos_type { npos = (size_type)-1 }; I assume it's the same problem as with IBMCPP. Don't know if MIPSpro can have 64-bits enums. 3) Threading is disabled: _SGI_MP_SOURCE is undefined If somebody could help me out with these, I'd be very grateful. My environment is IRIX 6.5.27 with MIPSpro 7.41, bjam 3.1.11 and I'm trying boost 1.33.0. I've modified the tools/build/v1/mipspro-tool.jam to use -64 and -mips4 as default. Probably not the way to do it, but I couldn't find the "proper" way within decent time Kind regards, Jeroen -- Jeroen Akershoek SARA - High Performance Computing & Visualization dep. tel: +31 20 5923000 fax: +31 20 6683167 Draco dormiens nunquam titillandus
