gcc-Link-action libs/test/build/bin/libboost_prg_exec_monitor.so/g cc/debug/runtime-link-static/shared-linkable-true/ threading-single/libboost_prg_exec_monitor.so ld: warning: option -d appears more than once, first setting taken ld: fatal: option -dn and -z[text|textwarn|textoff] are incompatible ld: fatal: option -dn and -G are incompatible ld: fatal: Flags processing errors collect2: ld returned 1 exit status What's causing this, and how do I fix it? I can't figure my way through these jam files just yet... Sparc Solaris 2.7, gcc-2.95.3, binutils-2.14 Any help would be... helpful. Thanks!
