Compiling PostgreSQL Plugin on Ubuntu 16.04.1

[max.t...@gmail.com]

Hi all,

I have been trying to compile the PostgreSQL plugins on Ubuntu 16.04.1 and I am getting an error during the linking phase that has to do with libiconv. Specifically, "Undefined reference to 'libiconv'" generated while linking a boost file. Here is the message:

Linking CXX shared library libOrthancPostgreSQLStorage.so
CMakeFiles/OrthancPostgreSQLStorage.dir/boost_1_59_0/libs/locale/src/encoding/codepage.cpp.o: In function `boost::locale::call_iconv(void*, char**, unsigned long*, char**, unsigned long*)':

I'm guessing this could be solved by installing the libiconv library and linking to it, however I am running into another set of compiler errors with that installation. So, two questions:
1. Is there a more straightforward way to get a hold of a PostgreSQL plugin that is compatible with Ubuntu 16.04.1?
2. If not, do you have any tips for installing libiconv or otherwise resolving this linker error?

Thanks!

The best way to get Orthanc and its plugins running on any Linux installation: use Docker

If you really need/want/enjoy to compile it by yourself, then, check the Orthanc Docker repository (https://github.com/jodogne/OrthancDocker).  Docker images are built from clean ubuntu 14.04 install.  The build script contains all the instructions to install all prerequisites and build all plugins.  You might need to adapt a few package names for 16.04 but that should not be a big issue.

Other tip when compiling Orthanc and its plugins: use -DSTATIC_BUILD=ON -DALLOW_DOWNLOADS=ON to reduce the dependencies issues.

Hello,

I have created a minimal build of the PostgreSQL plugins from source code on a raw Ubuntu 16.04.1 installation using Docker, and the linking works perfectly.

You will find my experimental Dockerfile attached to this message. Just type "sudo docker build -t orthanc-postgresql ." in the folder where you store the Dockerfile.

As a consequence, this is definitely an Orthanc-related problem here. This error reflects an issue with your Ubuntu box. Run synaptic, update the package database, upgrade all the packages, "autoremove" unneeded packages, and make sure nothing is broken.

That being said, I agree with Alain about Docker (https://github.com/jodogne/OrthancDocker), which is clearly the easiest way to bring the most recent version of Orthanc to any Linux box.

HTH,

Sébastien-

Perfect, I downloaded a fresh copy of the source and it compiled just fine. Thanks for the help!
