I am not sure if this is the list meant for such questions but here goes.

I am trying to compile a project where there are libraries and execs.
One of the libraries built by the project "libUtils.a" needs to be linked
against boost iostreams

When compiling with toolset gcc it uses a linking command with start-group
and end-group, but when compiling with toolset clang b2 uses a linking
command like :

"clang++" -L"/apps/bzip2/lib" -L"/apps/zlib/lib"   -o
"fixfast/bin/clang-linux-3.3/release/link-static/fixfast-mds_MCAST"
"fixfast/bin/clang-linux-3.3/release/link-static/fixfastDataD.o"
 "/apps/boost/root/bin.v2/libs/iostreams/build/clang-linux-3.3/release/link-static/libboost_iostreams.a"
~/infra_install/lib/libCDef.a -lbz2 -lz  -lpthread

This produces linking errors like undefined references in boost

When I reorder it to

"clang++" -L"/apps/bzip2/lib" -L"/apps/zlib/lib"   -o
"fixfast/bin/clang-linux-3.3/release/link-static/fixfast-mds_MCAST"
"fixfast/bin/clang-linux-3.3/release/link-static/fixfastDataD.o"  *
~/infra_install/lib/libCDef.a* *
"/apps/boost/root/bin.v2/libs/iostreams/build/clang-linux-3.3/release/link-static/libboost_iostreams.a"
* -lbz2 -lz  -lpthread
 i.e bring boost lib to the end it links fine.

What am I doing wrong ? Any pointers ?
