Eclipse Cdt Macros Syntax Error
content assist. eclipse disable syntax error The parser must be configured properly for eclipse c++11 it to find header files, otherwise the code analysis features may not have sufficient information available, and will not provide a complete analysis. Additionally it may be necessary to provide the parser with additional information on symbols (preprocessor macros) so that the preprocessing phase of the parser is correct. Configuring the Parser Tasks for configuring the parser: Setting up remote include paths Setting up symbols Configuring the Indexer The indexer used for C/C++ projects may be configured using the C/C++ General > Indexer properties page. For Remote C/C++ projects the RDT Remote Fast Indexer must be selected, otherwise the project will not be able to communicate with the remote index and none of the code analysis features will work correctly. Editor Warnings There is a known issue where sometimes the remote editor displays false warnings about syntax errors or invalid include directives. To disable editor warnings do the following: Use the workbench menu to open the Preferences dialog, Window > Preferences. Navigate to the Annotations preference page, General > Editors > Text Editors > Annotations. Select C/C++ Indexer Markers. Uncheck all the checkboxes. Click Apply.

I think it is marked as such by the CDT indexer. However, compilation (manually in a terminal) is no problem. This is a bit inconvenient however, since the elements on the line don't get indexed (so the call hierarchy tree isn't always correct, or the highlighting of elements, etc.) Why does Ecipse not like the line as it is? c indexing eclipse-cdt share|improve this question asked Apr 29 '09 at 13:38 Rabarberski 7,960165173 add a comment| 9 Answers 9 active oldest votes up vote 23 down vote accepted Eclipse CDT contains its own preprocessor/parser for analyzing your code and building an index. However, when you invoke a build CDT calls out to your system compiler, like gcc for example. There may be minor differences between

When I use common predefined macro __BASE_FILE__ Eclipse says Symbol '__BASE_FILE__' could not be resolved, but compilation is OK.

They just came out of the blue after having a working project. Anyway, I fixed it with a single option in workspace settings by setting: "Build configuration for indexer: Use active build configuration" The other option was "Use the build configuration specified in the project's indexer settings" and this is the one that wasn't working. I think it may have been corrupted after an eclipse crash. share|improve this answer answered Apr 9 '12 at 23:13 taloft 19113 1 Seems to be it is bug of the static analyzer, not the indexer. In any case it isn't working for me. Thanks for your efforts. –fasked Apr 10 '12 at 17:46 1 Hi talot, I couldn't find out how to access to th

Preprocessor Overview The C preprocessor, often known as cpp, is a macro processor that is used automatically by the C compiler to transform your program before compilation. It is called a macro processor because it allows you to define macros, which are brief abbreviations for longer constructs. The C preprocessor is intended to be used only with C, C++, and Objective-C source code. In the past, it has been abused as a general text processor. It will choke on input which does not obey C's lexical rules. For example, apostrophes will be interpreted as the beginning of character constants, and cause errors. Also, you cannot rely on it preserving characteristics of the input which are not significant to C-family languages. If a Makefile is preprocessed, all the hard tabs will be removed, and the Makefile will not work. Having said that, you can often get away with using cpp on things which are not C. Other Algol-ish programming languages are often safe (Pascal, Ada, etc.) So is assembly, with caution. '-traditional-cpp' mode preserves more white space, and is otherwise more permissive. Many of the problems can be avoided by writing C or C++ style comments instead of native language comments, and keeping macros simple. Wherever possi
