The following script takes care of downloading and compiling Flightgear from the | The following script takes care of downloading and compiling Flightgear from the git repositories with just one command execution for both 32-bit and 64-bit Debian based systems (Debian, Ubuntu). Pre-existing installed version (if any) of Flightgear are not touched at all since the script builds and installs everything under the directory in which it is launched. | ||
Necessary packages are installed via the apt-get system while libraries not included in the repositories are downloaded and compiled on the fly (i.e. [[Plib]], [[Simgear]] and [[OSG]]). | Necessary packages are installed via the apt-get system while libraries not included in the repositories are downloaded and compiled on the fly (i.e. [[Plib]], [[Simgear]] and [[OSG]]). | ||

There is a simple solution to the above errors: wait and relaunch the script after some time (hours or days), if (and generally happens) software developers repair or synchronize their code with the newly updated libraries, your Flightgear will compile fine as if the previous error never took place. | There is a simple solution to the above errors: wait and relaunch the script after some time (hours or days), if (and generally happens) software developers repair or synchronize their code with the newly updated libraries, your Flightgear will compile fine as if the previous error never took place. | ||
