After upgrading tu Ubuntu 10.04, I started having a problem using an
Autoconf-generated configure script to detect the Boost
libraries. Ultimately, the problem turned out to be that the
libraries just were not installed anymore! Here's what the
configure output looked like:
checking for boostlib >= 1.38.0... yes
checking whether the Boost::Filesystem library is available... yes
configure: error: Could not link against !
Note the two spaces before the "!". That's where the library name
should be, if it were even found. So apparently I had the headers
left over somehow, but the library had been uninstalled. Something to
keep in mind if you see such an error...
