ANTLR4.10.1 C++ target doesn't compile with CMake/MSVC2019/2022 32-Bit anymore (and more problems with C++ Target)

[Johann Anhofer]

1.) Building with CMake: 32-Bit Builds fail with 67 Linker errors: 

LNK2001    unresolved external symbol "public: static unsigned int __cdecl antlr4::misc::MurmurHash::update(unsigned int,void const *,unsigned int)" (?update@MurmurHash@misc@antlr4@@SAIIPBXI@Z)    runtime\XPathWildcardAnywhereElement.cpp.obj 

its always the same error on different files.

2.) Building with Visual Studio (Project Files)

Fails for all Plattforms with Files not found 

3.) Building with MsBuild (deploy-windows.cmd)

Fails for all Plattforms with Files not found 

e.g.

"c:\source\antlr4\runtime\Cpp\runtime\antlr4cpp-vs2019.vcxproj" (Standardziel) (1) ->

Hi Johann,

First of all - please consider usage of build automation tools for C++.
In the Java environment there are two eras - b.m and a.m - Before
Maven and After Maven.
In C++ we have Conan - something rather new - but Conan is what Maven
for Java is.
Antlr 4.10.1 compiles correctly for C++ MSVC 16 / 64 bit version correctly.
Project runs and parser works - here is a living example
https://github.com/michalwidera/Antlr4ConanExample
You will find some issues with MSVC on the 4.10 version.
In case of 32 bit version - just use --build missing for conan build
command if you want to build 32 bit version.
You can check what versions are compiled and tested here:
https://conan.io/center/antlr4-cppruntime

Looking in your post I think that you have linked in your project
files that came from 4.9.3 - AbstractPredicateTransition.cpp - etc.
They do not exist in runtime anymore.
Moreover you need to recompile your grammar with the 4.10.1 grammar compiler.
The Major number of versions (9->10) has changed and there are no bug
fixes but output of generated results can be different.
Input (.g4 file) remains the same - or it is backward compatible but
output could change.
Output in Antlr4 for C++ is a set of .cpp files and runtime.
You shouldn't link directly your project with inner runtime libraries
- compile it separately or use binaries from conan. As you wish.

That's mine advice,

Regards,
M.

I've found reference to these missing files in antlr4cpp-*.vcxproj files.
It looks like these files contain broken references to non-existent
files from 4.9.3
Try using CMake to build these sources or regenerate vcxproj files.
CMake works correctly here.

I don't know how to build those project files. If someone can build those files and give them to me, I can upload them to the website.

Dictation in use. Please excuse homophones, malapropisms, and nonsense.

Generating the project as stated in the Stackoverflow article for Platform Win32 and compile it with VS 2019 bring the same linker errors and much more.

cmake -DCMAKE_CONFIGURATION_TYPES="Debug;Release" -DCMAKE_GENERATOR_PLATFORM=Win32 -G "Visual Studio 16 2019" e:\projects\github\antlr4\runtime\Cpp

The project was freshly checked out from the github repository.

Compiling with cmake 

cmake -DCMAKE_BUILD_TYPE=Release -G Ninja e:\projects\github\antlr4\runtime\Cpp -DWITH_STATIC_CRT=OFF -DANTLR_BUILD_CPP_TESTS=OFF -DWITH_DEMO=OFF

cmake --build . 

in MSVC 2019/64 Environment builds correctly.

Doing the same in a MSVC 2019/32 Environment shows the above linker errors.

This was not the case before ANTLR 4.10, 4.9.3 builds for both platforms.

Best is to open a bug report against the C++ target on Github and someone from the C++ guys will take a look.
