I am trying to upgrade from Boost 1.30.0 to 1.31.0. My main interest is in the Regex library. I was pleased to build its libraries successfully for intel-linux, both .a and .so forms, using bjam. When trying to build the libraries for mipspro, it fails to build the .a forms, because it is trying to use ranlib. The bjam system is too unfamiliar to me to debug it, so I'm hoping somebody else can give me a remedy. (Note: I built bjam from the source in tools/build/jam_src, as described in the docs.) Here is the evidence: 69% bjam "-sTOOLS=mipspro" --stagedir=stage "-sBUILD=debug release <threading>single" stage [snip] mipspro-Archive-action bin/boost/libs/regex/build/libboost_regex.a/mipspro/debug/libboost_regex-mp-d-1_31.a --- C++ prelinker: bin/boost/libs/regex/build/libboost_regex.a/mipspro/debug/c_regex_traits.o --- [snip] Ranlib bin/boost/libs/regex/build/libboost_regex.a/mipspro/debug/libboost_regex-mp-d-1_31.a /bin/sh[2]: ranlib: not found ranlib bin/boost/libs/regex/build/libboost_regex.a/mipspro/debug/libboost_regex-mp-d-1_31.a ...failed Ranlib bin/boost/libs/regex/build/libboost_regex.a/mipspro/debug/libboost_regex-mp-d-1_31.a... ...skipped <@boost!lib>libboost_regex-mp-d-1_31.a for lack of <@boost!libs!regex!build/libboost_regex.a/mipspro/debug>libboost_regex-mp-d-1_31.a...
