this is the interface for the ipopt library which is required to compile. as stated in the setup.py file
# You will probably have to edit this file in unpredictable ways
# if you want pyipopt to work for you, sorry.
the easiest way to handle this is to adjust the setup.py accordingly:
# When I installed Ipopt from source, I used the
# --prefix=/usr/local
# option, so this is where I want pyipopt to look for my ipopt installation.
# I only installed from source because the ipopt packaging
# for my linux distribution was buggy,
# so by the time you read this the bugs have probably been fixed
# and you will want to specify a different directory here.
IPOPT_DIR = '/usr/local/'
adjust IPOPT_DIR to the path where the library has been installed on your system, which of course should has been conducted anyway.
EDIT:
If you are installing from source, just use --prefix=/usr/local for the configure script and compile and install the library by running make; sudo make install. Then you don't have to change the setup.py file.
