Hello, I am completely new to Boost framework. However like many others I am finding the initial stage(s) - namely that what is happening during the install seems particularly complicated. I guess most people here have been able to get going with Boost by glazing over the install and "it just works". Other people can run into a myriad of issues. So I guess my problem sits somewhere in-between those two extremes. One thing I cannot vouch for is not knowning (or wanting to know!) what boost is doing, and not seeing anywhere some firm list of requirements (eg system paths for libraries, etc) - I cannot be sure that my system has some misconfiguration somewhere that (is probably) causing this issue. However what is clear to me is that many other people can install boost on *their* systems with no apparent issue. So... whats the problem? In a nutshell, boost will only compile if i am UID=0 (root user / sudo superuser). As a normal, regular user boost install fails with the following error(s): janitors-Mac-mini:boost_1_46_1 id$ ./bootstrap.sh --show-libraries -n Building Boost.Jam with toolset darwin... Failed to build Boost.Jam Consult 'bootstrap.log' for more details bootstrap.log: https://gist.github.com/915620 It doesnt seem to matter the exact version of boost, or even the "CMake" version of boost. They all behave the same way. Whats unfortunate for me especially is that after successfully compiling jam (as root), and chown'ing down all the created files in the boost directory. The same error still seems to occur afterward. For example to compile such selected library. Has anyone seen anything like this? What could be the possible issue here? Is it really normal to compile everything as root?!!? Operating system - Mac OS-X Snow Leopard. Thanks in advance. dreamcat4 dreamcat4@gmail.com
