Hi , I have a problem, I download boost, I followed the steps on www.boost .org so first I build jam to obtain jam.exe, I copy it in my directorie where I installed boost. I run Msdos, I run VCVARS32 to set the environement of vc++ after I execute : bjam "-sTOOLS=msvc" install It compiles , however I have many errors and failed. At the end , It has copied in a directory boost include... the include , and the . lib. But I don't have all the libs I have the following message: ...failed updating 82 targets... ...skipped 60 targets... ...updated 4598 targets... You'll get better responses here if you use a subject appropriate to your issue, and do not reply to unrelated topics. Also please post using plain text. You can generally download a pre-built bjam.exe for you platform, in particular windows, which is implied in your post. You do _not_ need to run vcvars32 if your MSVC is installed in the default location as listed on the boost getting started page. Can we assume you download boost_1_33_1? What were the errors? What .libs didn't build? Are you aware that many boost libraries are header-only libraries and do not get compiled into .libs? Jeff Flinn
