First, I issued the following bcp command to copy the required libraries to /boost_minimal/boost
find /path/to/my/app | xargs {} bcp --scan {} /boost_minimal
As Voorhees said, no building script is copied.
By default bcp copies source files, but not Boost.Build, you can get Boost.Build as well with a: bcp build /boost_minimal Unfortunately, someone has added a new vital build file (boostcpp) to root which doesn't get copied.... I'll fix that in bcp.
In my case, I manually copied all files at the root of the original directory and the tools directory. Then I ran
./bootstrap.sh --prefix=/some/dir ./bjam ./bjam install
It generated headers in /some/dir/include, but no libraries in /some/dir/lib, which would happen if I did this on the original boost dir. I guess I'm missing some step when copying the build files to boost_minimal.
Not necessarily: is there actually anything for it to build? Remember a lot of Boost is header only - which libraries are you missing? HTH, John.
