In gprofng/libcollector, we need to generate the shared libraries:
% cat -n gprofng/libcollector/configure.ac
...
     35    LT_INIT
     36    AC_ENABLE_SHARED
     37    AC_DISABLE_STATIC
     38
     39    if test "$enable_shared" != "yes"; then
     40      AC_MSG_ERROR([Cannot set --enable-shared for 
gprofng/libcollector.])
     41    fi
     42
...


But it is so late to turn off the gprofng build.

Is there an easy way to find out if shared libraries are not supported ?
I want to know this in gprofng/configure.ac


Thank you,
