Tried latest version of antlr4 and the one from the readme. Got this error again, which is weird bc it used to work perfectly fine

I have three options to fix the broken build:
- Use an older compiler version
- Disable the
-Werrorflag in the build system - Fix the root cause of the problem
1. Older Compiler
The build fails with g++-13 but succeeds with g++-11 (I haven't tested at other compilers). Install the older compiler and run the build:
apt install -y g++-11
mkdir build && cd build
cmake .. -DANTLR_JAR_LOCATION=/path/to/antlr-4.8-complete.jar -DGRAMMAR_FILE=/path/to/Grammar-Mutator/grammars/ruby.json -DCMAKE_CXX_COMPILER=g++-11
cmake --build .
2. Disabling -Werror flag
- Create a file named
disable_Werror.patchwith the following content:diff --git a/CMakeLists.txt b/CMakeLists.txt index c94eba0..32ba7cf 100644 --- a/CMakeLists.txt +++ b/CMakeLists.txt @@ -49,7 +49,7 @@ endif () # Set -Wall -Wextra -Werror set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wall -Wextra -Werror") -set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wextra -Werror") +set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall -Wextra") # Do not disable assertions based on CMAKE_BUILD_TYPE. foreach (_build_type "Release" "MinSizeRel" "RelWithDebInfo") - Apply the patch:
git apply disable_Werror.patch - Build the project:
mkdir build && cd build cmake .. -DANTLR_JAR_LOCATION=/path/to/antlr-4.8-complete.jar -DGRAMMAR_FILE=/path/to/Grammar-Mutator/grammars/ruby.json cmake --build .
3. Fix the Root Cause
A Pull Request with the fixes has been created, but it is unlikely to be accepted: PR with fixes. Therefore, here are the instructions to apply the fixes manually:
-
Start build the project:
mkdir build && cd build cmake .. -DANTLR_JAR_LOCATION=/path/to/antlr-4.8-complete.jar -DGRAMMAR_FILE=/path/to/Grammar-Mutator/grammars/ruby.json cmake --build .* After some time, the build error will appear *
-
Make changes to
build/third_party/antlr4-cpp-runtime/antlr4-cpp-runtime-src/runtime/src/RuleContext.h:diff --git a/runtime/src/RuleContext.h b/runtime/src/RuleContext.h index 9ee0d2d..9de977a 100755 --- a/runtime/src/RuleContext.h +++ b/runtime/src/RuleContext.h @@ -128,6 +128,7 @@ namespace antlr4 { virtual std::string toString(const std::vector<std::string> &ruleNames, RuleContext *stop); + using ParseTree::operator==; bool operator == (const RuleContext &other) { return this == &other; } // Simple address comparison. private: -
Continue the build with the changes applied:
cmake --build .
