Install the latest versions of the software.Ĭreate a new C++ project. Use the “Oxygen” version of Eclipse, not “Luna”. You still need the -L and -l options to compile and link (previous slide).ħ Download and Install the Eclipse Plug-inĭownload and install the latest version “Oxygen” of Eclipse CDT (C/C++ Development Tooling) from Follow the instructions at under “Eclipse Installation”. dll file to the same directory as your compiler executable. If you don't know how to do this, a backup strategy is to copy the. Run the path command to verify it’s there. Therefore, you must first put the lib directory in your execution path. When you run the the generated compiler in Windows 10, it wants to use the dynamically linked library cygantlr4-runtime-4.7.dll in the lib directory.
To compile and link the ANTLR-generated code, you must use the 2011 dialect of g++ and tell it to use the ANTLR header files and library: If you did not put the library files in the standard location (or if you’re on Windows), you must add the -L option for the library directory before the -l option: For example, to run the executable expr on the input file t.expr: g++ -std=c++0x -I/usr/local/include/antlr4-runtime -lantlr4-runtime -o expr *.cpp -L/your/path/to/lib. Download non-MSVS library files from Remember which directory you put the library files in.ĥ Compile, Link, and Run the Generated Compiler Code
Unfortunately, the library files you download from the ANTLR site are for Visual Studio C++. Mac and Linux Install in the standard locations: Header files: /usr/local/include/antlr4-runtime Library files: /usr/local/lib/libantlr4-runtime.* Windows Remember which directory you put the header files in. In order to compile and link these generated compiler files, you need the ANTLR 4 header (.h) files and the ANTLR 4 library. cpp files for a parser, lexer (scanner), and parse tree routines. Run on the command line: Tip: Create a script or an alias: java -jar /your/path/to/antlr-4.7/ -Dlanguage=Cpp my.g4 export ANTLR_JAR="/your/path/to/" export CLASSPATH="$CLASSPATH:$ANTLR_JAR" alias antlr4="java -jar $ANTLR_JAR –Dlanguage=Cpp"ģ Download and Install the ANTLR 4 LibraryĪNTLR reads a.
