Hello, I'm trying to build Boost 1.34 using STLport 5.1(.0), but I get those error messages during link: /usr/bin/ld: cannot find -lstlportstlg.5.1 /usr/bin/ld: cannot find -lstlport.5.1 I use Linux and gcc 4.1.2. The static libs of STLport exist, but without the version number. Here is how I compile and install STLport: tar jxvf STLport-5.1.0.tar.bz2 cd STLport-5.1.0/build/lib make -f gcc.mak depend make -f gcc.mak make -f gcc.mak all-static make -f gcc.mak install make -f gcc.mak install-static cd ../.. cp lib/libstlport* $HOME/local/lib/ cp -R stlport $HOME/local/include/ Here are the available static libs: libstlport.a libstlportg.a libstlportstlg.a Note: I've just compiled STLport 5.1.3. Same files. They didn't change the build system. Note bis: I've asked the STLport devs if I should link my project with static or shared lib of STLport. They answered the shared lib as it is less troublesome. Maybe Boost should also do that. I modified user-config.jam by adding ($HOME == /home/torri): using stlport : 5.1.0 : "/home/torri/local/stlport" "/home/torri/local/lib" ; I compiled Boost with that command line: ../../boost-jam-3.1.13-1-linuxx86/bjam --prefix=$HOME/local stdlib=stlport --toolset=gcc If needed, I can provide more informations on my system.
