2 Davids, The output at the top of the compile after running: bjam "-sTOOLS=gcc" install > out.txt 2>&1 shows python errors followed by: ...found 13313 targets... ...updating 250 targets... And then throughout the compile there are a lot of link errors and FileClone operation not permitted errors. The the compile completes with a lot of skipped errors ending with: ....failed updating 110 targets... ...skipped 118 targets... ...updated 22 targets... So...the following list from the Boost site gave the order for compiling which I completed in order with my appended notes: 1. Download Boost http://boost.org/more/getting_started.html#step1. 2. Install Boost.Jamhttp://boost.org/more/getting_started.html#step2. ( I installed bjam to: /usr/local/bin/bjam) 3. Configure your compiler toolsethttp://boost.org/more/getting_started.html#step3. (This I did not do...I didn't know what they wanted me to do) 4. Go to Boost distribution directoryhttp://boost.org/more/getting_started.html#step4 . 5. Build and installhttp://boost.org/more/getting_started.html#step5 . Could some of this be the result of the fact that I didn't configure my compiler? Thanks guys... Douglas
