[LLVMdev] Error while linking LLVM files

[Wojciech Daniło]

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?
