When building BLFS-7.6 (systemd), I noticed that the configure script for Valgrind was not finding Boost even though I had installed it.
Turns out that in more recent versions of Boost, the multithreaded libraries no longer have, by default anyway, the "-mt" in their filenames (e.g. libboost_thread-mt.so). Valgrind, for one, looks for these libraries with the assumption that the "-mt" is present (it uses "-llibboost_system-mt" in its configure). Given that it is probable that some programs will look for "-mt" style libraries, and others will look for libraries without the "-mt," symlinks seem to be the most appropriate way to address this. I have tried it out and it fixes the issue I was having with Valgrind. This is the command I used to generate the symlinks once the libraries were installed in /usr/lib. If there is a more compact way to do this, I would love to know it. But this works. pushd /usr/lib && for file in $(ls -1 libboost*); do prefix=`echo $file | cut -d'.' -f 1` suffix=`echo $file | cut -d'.' -f 1 --complement` link_name=$prefix"-mt."$suffix ln -s $file $link_name done && popd Best, -wpl
