You may not define a member or variable by a value that references the same variable or member through a cyclic dependency.Ĭode::Blocks will detect the most obvious cases of recursive definitions (which may happen by accident), but it will not perform an excessive depth analysis of every possible abuse.You may not define a member by a value that references the same member.You may not define a variable by a value that references the same variable or any of its members.Variable and member values may contain arbitrary character sequences, subject to the following three constraints:.If 'libext' is a custom member we can only write $(#variable.libext) and not $(#variable)/libext. Currently, the custom member will overwrite the builtin member, but in general, the behaviour for this case is undefined. You may not define a custom member that has the same name as a builtin member.If you don't define a variable's base, it will not be saved (no matter what other fields you have defined). Everything else is optional, but the base is absolutely mandatory. Every variable requires its base to be defined.If Code::Blocks is given invalid character sequences as name, it may replace them without asking. Cyrillic or Chinese letters are not alphanumeric characters. Both set and global compiler variable names may not be empty, must not contain white space, must start with a letter and must consist of alphanumeric characters.The members cflags and lflags are empty by default and can be used to provide the ability to feed the same consistent set of compiler/linker flags to all builds on one machine.īeginning with revision 2664 (4 July 2006), Code::Blocks allows you to define custom variable members in addition to the builtin ones. It is generally recommended to use the syntax $(#variable.include) instead of $(#variable)/include, as it provides additional flexibility and is otherwise exactly identical in functionality (see mini tutorial). However, a user can redefine them if another setup is desired. The members include and lib are by default aliases for base /include and base /lib, respectively. The member base resolves to the same value as the variable name uses without a member (alias). The Code::Blocks team provides a list of recommended variables for known packages. This way, the amount of information that the user needs to provide is minimised. Although you can choose anything for a variable name in principle, it is advisable to pick a known identifier for common packages.
Names are freely definable, while some of the members are built into the IDE. Global compiler variables are structured every variable consists of a name and an optional member. Global compiler variables in Code::Blocks are discriminated from per-project variables by a leading hash sign.
No local layout information ever needs to be changed more than once.
Global compiler variables allow you to set up a project once, and any number of developers using any number of different filesystem layouts will be able to compile and develop the project. The concept of global compiler variables is an unique new solution for Code::Blocks which addresses this problem. If one does not pay attention, this can happen easily for example after changing a build flag to make a release build. In the case of project files, care must be taken to not accidentially commit a locally modified copy. Working as a developer on a project which relies on 3rd party libraries involves a lot of unnecessary repetitive tasks, such as setting up build variables according to the local filesystem layout.
