无法安装IPOPT for python（缺少库依赖性）

Question

I built IPOPT from source at /usr/local/ Then I tried to install ipopt for python python setup.py install

However the installer complained (error) that it could not locate IpStdCInterface.h
I then modified the content of setup.py file as follows: (line 1 and 3 had wrong paths)

    IPOPT_ICLUDE_DIRS=['/usr/local/include/coin']
    IPOPT_LIBS=['ipopt', 'coinhsl', 'coinlapack', 'coinblas', 'coinmumps', 'coinmetis']
    IPOPT_LIB_DIRS=['/usr/local/lib/']
    IPOPT_DLL=None

I modified the first and third line to point to the correct directory.

Now, the lib directory path (in the third line above) contains a library file named libipopt.so , libipopt.so.0 , libipopt.la (same name, different extensions).

The setup is now not complaining about IpStdCInterface.h but it is unable to find the libs

x86_64-linux-gnu-gcc -pthread -shared -Wl,-O1 -Wl,-Bsymbolic-functions -Wl,-Bsymbolic-functions -Wl,-z,relro -fno-strict-aliasing -DNDEBUG -g -fwrapv -O2 -Wall -Wstrict-prototypes -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security -Wl,-Bsymbolic-functions -Wl,-z,relro -Wdate-time -D_FORTIFY_SOURCE=2 -g -fstack-protector-strong -Wformat -Werror=format-security build/temp.linux-x86_64-2.7/src/cyipopt.o -L/usr/local/lib/ -lipopt -lcoinhsl -lcoinlapack -lcoinblas -lcoinmumps -lcoinmetis -o build/lib.linux-x86_64-2.7/ipopt/cyipopt.so

/usr/bin/ld: cannot find -lcoinmetis
collect2: error: ld returned 1 exit status
error: command 'x86_64-linux-gnu-gcc' failed with exit status 1

Those libs should be provided by the libipopt.so file? Or do I need to install some other package?

Answer 1

Well, i have a same problem as you. My solution was add the following commands in .bashrc:

export IPOPT_HOME="/opt/CoinIpopt"

export PATH="${PATH}:${IPOPT_HOME}/bin"

export LD_LIBRARY_PATH="${LD_LIBRARY_PATH}:${IPOPT_HOME}/lib"

/opt/CoinIpopt is the path which the IpOpt was installed.
