Hi!
I’m trying to learn LLVM and I want to compile the Kaleidoscope compiler.
according to:
http://llvm.org/docs/tutorial/LangImpl3.html
I’m compiling it with:
clang++ -g -O3 test.cpp llvm-config --cppflags --ldflags --libs core -o toy
and it indeed works.
The problem is that when using eclipse it forces me to divide the compilation into two steps:
g++ -O0 -g3 -Wall -c -fmessage-length=0 llvm-config --cppflags --ldflags --libs core -MMD -MP -MF"src/lunac.d" -MT"src/lunac.d" -o “src/test.o” “…/src/test.cpp”
(which compiles fine)
and:
Invoking: Cross G++ Linker
g++ llvm-config --cppflags --ldflags --libs core -o “test” ./src/test.o
which gives me error:
./src/test.o: In function NumberExprAST::Codegen()': /home/wdanilo/dev/lunac/Debug/../src/test.cpp:358: undefined reference to llvm::APFloat::APFloat(double)’
/home/wdanilo/dev/lunac/Debug/…/src/test.cpp:358: undefined reference to llvm::getGlobalContext()' /home/wdanilo/dev/lunac/Debug/../src/test.cpp:358: undefined reference to llvm::ConstantFP::get(llvm::LLVMContext&, llvm::APFloat const&)’
[…]
Why Linker is not working with these flags? How can I fix it?
