install libbase eroor

[Luigi Palmieri]

Hi all,

I am new in using or-tools. Two questions.

1. I have some issues: while attempting to run "make test" I received the

following error messages:

make test

bin/golomb --size=5

bin/golomb: symbol lookup error:

/media/data/or-tools-read-only/lib/libbase.so: undefined symbol:

_ZTIN6google8protobuf2io14ErrorCollectorE

make: *** [test_cc] Error 127

I am using Ubuntu 12.04, and following the guide in here (

https://code.google.com/p/or-tools/wiki/AGettingStarted). I have run the

following commands:

sudo apt-get install bison flex python-setuptools python-dev autoconf

libtool texinfo gawk

sudo apt-get install openjdk-7-jdk

make third_party

make install_python_modules

make

make all

make test

Any suggestions?

2. I'd like to use or-tools to solve a Minimum cost flow problem. Is there

an example that shows how to solve it?

Thank you for your help,

Best Regards,

Luigi
