I have a couple of perl projects that make use of the GD::Graph module and I needed to set them up on a new machine. I was expecting to install the module without any problems but I was wrong. With a live internet connection I started off by starting the CPAN shell by typing the following in a bash shell<\/p>\n
sudo perl -MCPAN -e shell<\/p>\n
Since it was the first time I had run this command on this particular machine I had to answer a lot of questions but simply selected the defaults for everything as this usually works for me. Once in the CPAN shell I entered<\/p>\n
install Bundle::CPAN<\/p>\n
and selected all of the defaults again. Once the CPAN bundle had finished installing I tried to install GD::Graph by typing<\/p>\n
install GD::Graph<\/p>\n
but it failed with hundreds of errors – the first of which was<\/p>\n
GD.xs:7:16: error: gd.h: No such file or directory<\/p>\n
This was fixed with the following apt-get command (in the bash shell)<\/p>\n
sudo apt-get install libgd2-xpm-dev<\/p>\n
back in the CPAN shell I still couldn’t get GD::Graph to build and I guessed this was because of some left over files from the failed build. I don’t know the command to clean things up inside the CPAN shell and am too lazy to read the docs so I simply went into the .cpan\/build directory in my home directory and deleted anything that started with GD – eg<\/p>\n
rm -rf GD-2.35-HC_vkB<\/p>\n
rm -rf GDGraph-1.44-Evfibe<\/p>\n
and so on. Those strings at the end (VkB and so on) look random so they might be different on your machine. Then I went back into the CPAN shell and ran<\/p>\n
install GD::Graph<\/p>\n
again. There were a few dependencies which the script fetched and installed for me but everything worked smoothly. With a bit of luck these notes will be of use to someone else out there – please let me know if this is the case.<\/p>\n","protected":false},"excerpt":{"rendered":"
