Hello, I am building Boost and making progress. Thus far wondering what options to provide my B2. I added the zlib include path to the include="...;/path/to/zlib;...", and now seems to be wanting the LIB path? LINK : fatal error LNK1181: cannot open input file 'z.lib' LINK : fatal error LNK1181: cannot open input file 'zlib.lib' LINK : fatal error LNK1181: cannot open input file 'zll.lib' LINK : fatal error LNK1181: cannot open input file 'zdll.lib' Which option is that for B2? After that, it is on to finding bzip? fatal error C1083: Cannot open include file: 'bzlib.h': No such file or directory Is there a source download similar to that of zlib? I think I'm pretty close but for a handful of obscurish third party dependencies. Thanks! Cheers, Michael Powell
