So what do you define as best for you? Code quality? Library features? Clear, concise error messages?
I personally use GCC and clang. Both are fine, free compilers, each with slightly different quirks. The thing I can recommend: IDEs hides build process and sometimes makes projects unportable without the same IDE installed by somebody wants to build ypur program. If you want to progress to other languages, you can write them yourself - LLVM is a well known compiler development toolchain, includes tutorial on writing Kaleidoscope language in manuals. It is not suitable for dynamic languages, but if you anderstand how to implement your language in C semantics, LLVM is good platform for you.

What is the best c compiler in Mac? It encourages another best practice by making your class' destructor virtual.
We can enter the source code for these classes as seen in Listings 1 and 2. What's this code doing?
Write C/C++ on Mac with Eclipse, no Xcode – The Mac Observer
Well, our Lottery class has two attributes. The ticketSize attribute is the number of numbers on the lottery ticket. The maxNum is the maximum number on the ticket. Later, we'll use the Florida state lottery as an example. There, you pick six numbers from 1 to 53, so ticketSize would be 6 and maxNum would be The generateNumbers method generates an array of numbers corresponding to the numbers on a lottery ticket.
It uses the STL function rand to generate numbers randomly. The allNums array is used to keep track of what numbers have been generated so far, so we can make sure we don't get a duplicate number on our ticket. Finally, the printTicket creates a string representation of our ticket.
When you save the files, Eclipse builds your project automatically. Again, if you save the project, it should be compiled and you should see compilation messages in the console, as shown in Listing 3. You might have noticed that we made the printTicket method virtual when it was declared in the header file.
That will allow us to subclass Lottery and override this method. We wanted to do that because some states have a lottery with a "mega" number. This is a separately drawn number that any ticket must match in addition to the other numbers drawn. Let's create a MegaLottery class for these states that will subclass Lottery.

This time in the New Class wizard, we'll declare our new class in the same namespace, but call it MegaLottery. To subclass Lottery , select the Add button next to the Base Classes section. This will bring up the Choose Base Class dialog. You can start typing the name of the class, and Eclipse will narrow the list of base class candidates quickly. You'll want to select Lottery and click OK.
We can enter the code for MegaLottery , as shown in Listings 4 and 5. This is the max value that the mega number can take. It overrides the printTicket method. It uses the base class to generate the first part of the ticket, then it generates the mega number and appends it to the string representation of the ticket. We just need a way to create the various lotteries.
We'll use a class Factory Pattern to do this. We'll do this by adding a LotteryFactory class. We want all Lotteries to come from the same factory, so we'll make LotteryFactory a singleton. The code for it is in Listings 6 and 7. Listing 7 shows the implementation file for the LotteryFactory class. The LotteryFactory has an enum of the different types of lotteries. We've only put in Florida and California in the example, but it shouldn't be hard to add as many as you want.
The LotteryFactory 's constructor seeds the rand function used by our lottery classes. We just need to implement our executable's main method. This will bring up the Create run configuration interface for the Lottery project. You'll need to select its executable by clicking the Search Project button. You can select the binary that Eclipse created for you and click OK.
Just click Run , and the program should run in your console. The code below shows some sample output. Contrary to other tools, Eclipse does not need administrative rights, does need not be installed in a system location, and does not need not be a single instance on a system. Actually you are encouraged to install multiple instances of Eclipse, possibly one for each project type, to avoid mixing plug-ins from different sources in case different project types. The minimum CDT version is 9. Please note that starting with 4. The following samples are from a slightly older Eclipse 4.
Other platforms may behave slightly different, but the idea is the same. Be sure your Eclipse is 4. If you already installed the toolchain and, on Windows, the build tools in the default locations, as suggested in the above steps, the plug-ins might have automatically discovered them. The above definition will make the toolchain and build tools accessible to all projects in all workspaces.
How To Install Eclipse CDT 8.2 and Get Started
If needed, you can define different paths per workspace Workspace Tools Paths or even per project Tools Paths in the project properties. To check if the paths definitions are effective, go to the project properties page and identify the PATH variable. There are cases when the on-line access to the SourceForge mirror servers might not be reliable. In these cases the Eclipse update system may fail. For example:. To overcome this, disable the use of GTK 3, by adding the following line to your environment:.
If, for any reason, a global setting is not possible, the GTK version can be set in eclipse. This requirement is anecdotal and appears on some forums; the Eclipse documentation does not mention it.
