After updating my guacamole installation to 0.6.2 and struggling for some time to get the autologin to work again, I decided it’s time for some little instructions (mainly for my future self \ud83d\ude42 )
\n—-Update 6.12.12— added instructions for guacamole-0.7.0<\/p>\n
Here we go:<\/p>\n
#euse –enable cgi vnc
\n#emerge tomcat guacamole php
\n#\/etc\/init.d\/tomcat start
\n#\/etc\/init.d\/guacd start<\/p>\n
make guacamole itself work via tomcat and test it…<\/p>\n
Now it gets tricky… make php work within the guacamole application.<\/p>\n

\n<\/a>Place the .war file in the webapps folder and access it once via http. This will unpack its content and one can pick the three jar files from WEB-INF\/lib and copy them over to the guacamole’s WEB-INF\/lib. Also copy the whole cgi folder over to the guacamole directory. In it, I had to place a link to the php-cgi binary.
\nln -sf \/usr\/bin\/php-cgi \/var\/lib\/tomcat-7\/webapps\/guacamole\/WEB-INF\/cgi\/i386-linux\/php-cgi
\nNext place the following lines in the guacamole’s web.xml under <web-app><\/p>\n
