Closed Kidist-Abraham closed 6 years ago

Kidist-Abraham commented 6 years ago

While building relex on rapberryPi, I encountered an error of "package org.slf4j does not exist" even after i add the " slf4j-1.7.25.jar" file in to /usr/share/java folder.

Hi @Kidist-Abraham, what kind of Linux do you use on Raspberry PI? If it is Ubuntu you can use sudo apt-get install libslf4j-java liblogback-java to fix setup.

Manually you can add following symlinks to make it work:

${PREFIX}/slf4j-api.jar -> ${PREFIX}/slf4j-api-1.7.25.jar
${PREFIX}/logback-core.jar -> ${PREFIX}/logback-core-1.2.3.jar
${PREFIX}/logback-classic.jar -> ${PREFIX}/logback-classic-1.2.3.jar

You can also use maven to build RelEx without managing dependencies by hand. But in such case you need manually prepare run environment. Automatic run environment preparation is raised as https://github.com/opencog/relex/issues/267.

Hello @vsbogd , Thank you for the help. The OS is raspbian. I manually added the library and it runs. But I was thinking to add the maven build to the installation script. I will check that out.

Just found recently that Raspbian is based on Debian, so at least on last version which is based on Debian Stretch sudo apt-get install libslf4j-java liblogback-java should work properly.
