Binary not found
4 stars based on
You must have a working GCC cross development toolchain. This includes several parsers, compiler options eclipse c binary not found launch failed are working silently in the background to provide all kind of additional information while you are editing the source code.
Although sometimes a little bit tricky, just a few configuration steps are required to make these helpful features available. If already running, terminate Eclipse and start it again. If still in the virgin state, Eclipse will present the welcome page. Click on Workbench in the upper right corner. The so called Resource Perspective appears. We will later change to the C Perspective. The project name events will be added automatically, though, you may change it, if you like.
If this dialog doesn't appear, you will be back in the Resource Perspective. We do not need the Resource Perspective any longer. You have now created a C cross development project in Eclipse. As you may have noticed already, there are several warning signs. They appear, because the code parser is not yet able to get the full picture of project's source code. Read on, we will try to solve this now. This includes not only the application code, but also the compiler options eclipse c binary not found launch failed and all related header files.
As you probably assume, Eclipse needs to know a few things about your compiler configuration and the linked libraries. It is often a bit difficult to figure out these settings, but don't worry. In the worst case Eclipse will misinterpret parts of your code, displaying false warnings or errors. Nevertheless your code will still build and run fine. If you are in a hurry, you may simply skip this chapter. In a first step we will tell Eclipse, where to find the header files.
Open the project properties by selecting Properties in the Project menu. If not already selected, click on the tab that is titled Includes. You can now use the action buttons on the right to add, edit, delete and move include directories. Which directories to choose? Some are provided on to the compiler as command line options pre-pended by -Iothers are built-in. Those on the command line are added by the Configurator when creating the Makefiles.
Usually there are only two of them. If the source code refers to a header file not found in the directories given on the command line, the preprocessor will search so called built-in paths.
Their location depends on the toolchain configuration. Note, that the sequence of the entries is important. In general, the most target specific headers must come first, while the most general header files should be located in the path that is the last entry in the list. Like with include paths, symbols more precisely named preprocessor macros may be given on the command line or may be built-in.
Click on the Symbols tab to enter a list of macros. In most cases a single one is used, the name of the target board. On the other hand, the list of built-in macros is quite large. In most case the following macros definitions will be sufficient. It is sometimes difficult to determine the correct include paths and symbols to let Eclipse correctly find all header files.
If you are like me, you will be compiler options eclipse c binary not found launch failed bugged by any red underlined part in your source code. At least these paths must be added to the project properties Paths and Symbols.
Furthermore you must add the built-in paths of the compiler, which can be retrieved by the following command. We can also use compiler options eclipse c binary not found launch failed command line to get a sorted list of pre-defined symbols macros. For this, it is required to specify the architecture. In contrary to the last chapter, configuring a correct build environment is essential. Otherwise you won't be able to build the binaries. You may still use the command line to execute make, but in that case Eclipse won't be useful any more.
Luckily we chose a Makefile project, so most of the configuration items had been put into the Makefiles by the Configurator. Instead, non-existing variables will be appended to the initial environment.
If you define a variable, which already exists, then its value will be replaced. Not really required for building, but essential for debugging: The parser for the binary. If no problems were found, Eclipse will create the final binaries of our events application. To make sure, that your code is properly rebuilt after source code changes, you should clean the project first before re-building it. Quite often, specifically on Windows PCs, the first attempt failed and no target will be built.
If you are lucky, Eclipse will provide a useful error message in the Console. Sometimes there is no console output at all and nothing is built.
Sometimes you will use more advanced Makefiles, which may require additional environment settings. If this works, you should create a command line window from within Eclipse, which allows you to further evaluate your environment. This is not always that easy. On Windows I found the following solution.
It is very important to use a tab in front of test. Now create a batch file mycmdline. To start the batch file, make sure that the project is selected in the Project Explorer and then select Make target Enter the name cmdline and keep the option Same as the target name enabled. When you click OK, you will see your new target in the list. Select it and click on Build. A new command line compiler options eclipse c binary not found launch failed should open, which you can use to further evaluate your problem, test environment settings etc.
If you finally succeeded in building the project, then you are ready to configure the debugger. Hardware Firmware Tools Download Community.
In the File menu select New and Project For other targets, different macros are used. The value specifies the major version. This one is for the Ethernut 5 board, other compiler options eclipse c binary not found launch failed use different ones. Solving Parser Problems It is sometimes difficult to determine the correct include paths and symbols to let Eclipse correctly find all header files. Furthermore you must add the built-in paths of the compiler, which can be retrieved by the following command arm-none-eabi-cpp -x c -v In any case, you should only absolute paths to the project properties, e.
Click OK to save your settings. To test your configuration, open the Project menu and select Build Project. Cannot run program "make": Error reports from make itself are quite verbose, but less informative. The system cannot find the file specified. Add a new target to the end of your Makefile cmdline: Next Step If you finally succeeded in building the project, then you are ready to configure the debugger. Actually not really required for source code browsing, but may help, when later running the debugger.
