install_dependencies.sh fails with following error message

[HWiese1980]

I now get the following error message during installation of dependencies:

Is Boost 1.58 too old?

[jmachowinski]

Es fehlt die Class loader lib

[HWiese1980]

Ja, ist das nicht eine "Dependency", die durch "install_dependencies" installiert werden sollte?

[arneboe]

This does not happen on the CI and also not on my pc. I'll fix it :)

[HWiese1980]

Weird...

Awesome! 👍

[planthaber]

class loader is a apt package on ubuntu:

apt install libclass-loader-dev

[HWiese1980]

True, but doesn't install_dependencies include system dependencies like that?

[HWiese1980]

I mean, install_dependencies implies that all dependencies are installed, no exceptions...

[planthaber]

That's what autoproj does, we cannot cover all the system dependencies for all the distributions, btw. the Readme tells you what packages to install on ubuntu:

https://github.com/envire/envire-envire_core/blob/master/README.asciidoc#standalone-installation

[arneboe]

Right now the install script does not cover system dependencies. That could be changed, however :)

[HWiese1980]

Okay, I've manually installed libclass-loader-dev. Now it's failing with the following error message.

The allegedly missing libraries are definitely there. What irritates me however is the colon right in front of the path.

[HWiese1980]

I've made sure all system dependencies not installed by install_dependencies.sh are installed before I started install_dependencies.sh. The error shown in #44 (comment) happens nevertheless.

[planthaber]

Just tested in a clean docker ubuntu:18_04 image and it worked.

The missing Part in the Readme is that install_dependencies.sh generated a env.sh script which ghas to be sourced in order to find the custom build dependencies

[HWiese1980]

I have Ubuntu 16.04. Is that a problem?

[planthaber]

on 16.04 the pkg-config file of class_loader seems to be broken:

In
/usr/lib/x86_64-linux-gnu/pkgconfig/class_loader.pc

remove all ":" from the -l statements

Libs: -lclass_loader -l/usr/lib/x86_64-linux-gnu/libboost_thread.so -l/usr/lib/x86_64-linux-gnu/libboost_system.so -l/usr/lib/x86_64-linux-gnu/libpthread.so -l/usr/lib/libPocoFoundation.so -ldl -l/usr/lib/x86_64-linux-gnu/libconsole_bridge.so

[planthaber]

we could also add class_loader to the install_dependencies script:

build https://github.com/ros/class_loader melodic-devel class_loader "$PREFIX -DBUILD_SHARED_LIBS=TRUE"

[arneboe]

Is this still relevant?

[pierrewillenbrockdfki]

In the sense that ubuntu 16.04's class_loader's pkgconfig.pc is still broken, yes.

[HWiese1980]

Just tripping over this again. Could the bug be fixed automatically by the install_dependencies.sh script? Does that make sense?
