I installed libffi-3.0.11, because another program needs that. But after the installation the other program (by calling the comand ./configure)don’t recognize that libffi is installed. Do I have to set a environment variable? Or are all variables set automatically?
usually there is a LIBPATH, you should try to include the directory where your lib resided into this path. In addition, if you have a default bash
export LIBPATH=/your/libffi/path:$LIBPATH
I highly recommend to put this into a script and load it whenever you login automatically so that you don’t need to repeat this step
/home/yourhome/.profile <- make sure you insert it into this file and its loaded automatically
Here is a guide how to do the task:

The parameter you probably need is the following:
./configure –libexecdir=/usr/lib:
If you have installed the libffi library properly this should completely solve your problem.
