Not Able To build this project

After running make command following Error is thrown while building this project

Making all in src
make[1]: Entering directory '/home/sir/llvm_proj/aplc-master/build/src'
make[1]: *** No rule to make target 'parser.h', needed by 'all'. Stop.

"parser.h" is a symlink that should have been created by the CMake script:

aplc/src/CMakeLists.txt

Line 32 in 745aa7a

execute_process(COMMAND ${CMAKE_COMMAND} -E create_symlink ${CMAKE_CURRENT_BINARY_DIR}/parser.hpp ${CMAKE_CURRENT_BINARY_DIR}/parser.h)

I'm not sure why that didn't work.

In any case, I don't think this project still builds with modern versions of LLVM.

Any continued interest in porting this to a more recent LLVM?

I've updated the library paths, but I still get the following error (first of many)

/home/usr/dev/aplc/src/codegen.cpp: In constructor ‘llvm::UnresolvedType::UnresolvedType(int)’:
/home/usr/dev/aplc/src/codegen.cpp:41:53: error: ‘NumTypeIDs’ was not declared in this scope
     UnresolvedType(int x) : Type(mod->getContext(), NumTypeIDs), x(x) {}

I've got no immediate plans for updating this to newer LLVM versions -- I'd gladly accept PRs, however!

[cannadayr]

Do you happen to remember what version of llvm you used to develop?

[jiixyj]

At the time of the last commit LLVM 3.0 was the latest version, so it should probably work with it.

If anyone is still interested. I could make it run

First you need to add pthreads to the src/CMakeLists.txt

It should then look like this:

find_package(Threads REQUIRED)
target_link_libraries(aplc
    LLVMipo
    LLVMInstrumentation
    LLVMScalarOpts
    LLVMInstCombine
    LLVMTransformUtils
    LLVMipa
    LLVMAnalysis
    LLVMTarget
    LLVMCore
    LLVMSupport
    ${ICONV_LIBRARY}
    ${CMAKE_THREAD_LIBS_INIT}
)

(the find_package and the ${CMAKE_THREAD_LIBS_INIT} are new)

then you can use a docker container with llvm3.0 to run it.

docker run --rm -it -v "$PWD":/workspace -w /workspace nwtgck/llvm:3.0 bash
apt update && apt install -y build-essential automake autoconf libtool bison flex clang pkg-config
export PATH="/usr/local/llvm/llvm-3.0/bin:$PATH"
mkdir build
cd build
cmake ..
make
./aplc ../../examples/example.apl

The simple apl dialect however doesn't cover much and doesn't support unary operators yet. I had to add that and then it still wasn't able to parse my examples without segfaults
