&eelopment Getting Started

tFs relatiely easy to get started working on +ono&eelop' but this page aims to make it

easier to get o the ground.

youFre on "S B you can also try IddsglFs one step

installJ httpsJ==github.com=ddsgl=monodeelopbuild

Setting up an 9nironment

+ono&eelop doesnFt reKuire the ery latest ersion o +ono' and we speciically depend onGT6L eatures no later that GT6L 2.4. That said' using a recent release o +ono and Gtk#

is likely to improe reliability and perormance.

It is strongly recommended to use a ac!aged release o" #ono or your distribution'

as it is ery easy to mi up conlicting +ono ersions i installing rom source. you mustinstall +ono rom source' set up a Parallel +ono 9nironment.

+ake sure you hae git installed' and check +ono&eelop out rom GitHub.

@uilding and nstalling

"pen a terminal in the topleel +ono&eelop directory' and run

.=conigure proileMcore

t may ail because o missing dependenciesN install them' and rerun the command.

There are a number o other proiles that can be usedN the command

.=conigure help

eplains how they are used.

:et' use

to build +ono&eelop.

Since youFre working on the deelopment ersion' itFs best not to install itN instead' you canuse

make run

to run it without installing it.

t is a good idea to keep separate copies or using and deeloping.

you do install +ono&eelop' it is best to run the current ersion uninstalled' to make sureit works' beore installing it.

%orking on +ono&eelop

@eore hacking on +ono&eelop' donFt be araid to ask Kuestions on #monodeelop>C or +ono&eelop mailing list. People will be able to gie you pointer about where to start

and how best to approach the problems your are trying to sole. There are also numbero *rticles on the +ono&eelop architecture and on implementing addins.

The +ono&eelop solution can be opened rom +ono&eelop' and builds can be preormed

orm within +ono&eelop. ndeed' some parts o the build 8such as Stetic code generation;must be perormed within +&. Howeer' the modiied +ono&eelop must be run rom a

terminal with

make run

ou should ollow our contribution rules' or code style and licensing.

*ter you hae made your changes' commit them with a descriptie message and open apull reKuest on GitHub.

Troubleshooting the @uild

the +ono&eelop build ails' there are a number o possible ies.

the build commands ailed' try a clean rebuildJ

make cleanN make

and i any that are in conlict' or delete any that hae changed unnecessarily.

the build system ailed' check or changed iles and rerun the conigure script.
