Sorry for the repost, but it looks like the formatting on my previous post was messed up, and I wouldn't blame people for not reading it I am on windows using the latest version of the intel compiler (set in my user-config.jam). I was able to do a debug build of everything using: bjam link=static debug stage But when I tried to do a release build, it is popping up a spirit error for serialization(fails with or without mpi). Any ideas on a workaround or if this is a legit bug? The main error in the build output is: C:\apps\boost\boost_1_38_0\boost\spirit\home\classic\utility\impl\chset\range_run.ipp(142) (col. 21): internal error: 0_1504 compilation aborted for libs\serialization\src\xml_grammar.cpp Full output: bjam --with-mpi link=static release stage ...patience... ...found 1080 targets... ...updating 4 targets... compile-c-c++ bin.v2\libs\serialization\build\intel-win\release\link-static\thre ading-multi\xml_grammar.obj icl: command line remark #10010: option '/Op' is deprecated and will be removed in a future release.
