similar to: [LLVMdev] Getting Kaleidoscope to compile

Probably you missed to install llvm-dev package with headers for llvm. 2010/1/4 Russell Wallace <russell.wallace at gmail.com> > Hi all, > > I've started work on a new programming language for which I am > considering using LLVM as the backend, and trying to experiment with > it using the Kaleidoscope demo compiler. > > Taking the full source listing from >

I am new to llvm so I might be missing a critical step. My system is Fedora 12 but this also happens in Mac OS X 10.6.2. Here are the steps I used to compile llvm: export TARGETS=x86,x86_64,cpp export INSTALLDIR=/home/rovitotv/llvm ../llvm-2.6/configure --prefix=$INSTALLDIR --enable-bindings=none --enable-targets=$TARGETS --enable-optimized --with-llvmgccdir=$INSTALLDIR

First, you have to call llvm-g++ to use the llvm-gcc front end, but it doesn't matter here. I'd like to suggest that you use pastebin to put your code and the send us the link, so that we can download it. The problem is that TheExecutionEngine is set to NULL (maybe because of a previous error), but it will be really better if you use pastebin. On Wed, Feb 17, 2010 at 6:01 AM, Todd Rovito

Greetings, I am having trouble getting the Kaleidoscope example to build from tutorial #3 on Mac OS X 10.6.2. I didn't have too much trouble getting llvm-2.6 and llvm-gcc-frontend to build. Thanks for the help. Here are the steps I followed: Environment variables for build export LLVMOBJDIR=/opt/llvm export TARGETOPTIONS='--with-arch=nocona --with-tune=generic' export

I tried apt-get install llvm-dev just now, and it says it was already installed, and when I again try compiling toy.cpp, it gives the same set of error messages.

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

Hi, Try these scripts to build llvm and llvm-gcc. It's the ones I use and I managed to get them to work when I saw another build script using those CFLAGS. They compile llvm and stuff using only x86_64, but you can then generate code for i386 (just use a different backend). The configuration options are at the top of the scripts and they install llvm and llvm-gcc to ~/llvm. Regards,

It does take one parameter. Here's the important bits: // My Function extern "C" void print(double X) { printf("%f\n", X); } // Args type std::vector<const Type*>

Hello , I have build llvm from release_38 branch ( only llvm and clang ) and install it. My DYLD_LIBRARY_PATH points to installation-directory/lib. I am compiling example files for Kaleidoscope with following command : clang++ -g toy.cpp -std=c++11 `llvm-config --cxxflags --ldflags --system-libs --libs core mcjit native` -O3 -o toy but it fails with following error: Undefined symbols for

Hi, all I'd like to write a code that can build different codes based on LLVM version. Like code snippets in the below. #ifdef __LLVM_29__ PHINode *PN = Builder.CreatePHI (Type::getDoubleTy(getGlobalContext()), 2, "iftmp"); #elif __LLVM_28__ PHINode *PN = Builder.CreatePHI (Type::getDoubleTy(getGlobalContext()), "iftmp"); #else assert ("wrong

I am trying to get a handle on IR builder, at least some basics. I ran through a tutorial here: Create a working compiler with the LLVM framework, Part 1 <http://www.ibm.com/developerworks/library/os-createcompilerllvm1/>, and it worked well enough. I have some simple code that creates a hello world IR. I am trying to now bring in some concepts from the Kaleidoscope tutorial, namely

Hello All I 'm studing LLVM/Clang and trying to follow the Kaleidoscope tutorial (Release 2.6 version). I found some minir docu-bugs and added them to Bugzilla. However, Now I found a show-stopper for me, the toy (v4) demo does build, but does crash, on any input. Even a simpe ';'! Looking into the (demo-code) found the that the JIT can't be build/ created,/loaded/... Which

I don't know if the toy program in chapter 4 of the tutorial implementing Kaleidoscope in llvm with C++ is part of your regression suite, but with the version of llvm I installed last weekend, it does not compile: hendrik at lovesong:~/dv/llvm/tut$ g++ -g toy.cpp `llvm-config --cppflags --ldflags --libs core jit native` -O3 -o toy toy.cpp: In member function ‘virtual llvm::Value*

I read the tutorial doc and some info of SSA, finally understand it. Thanks for your help. And the segmentation error of loading arguementation occurs, (gdb error info) Program received signal SIGSEGV, Segmentation fault. 0x0855bb68 in llvm::LoadInst::LoadInst(llvm::Value*, char const*, bool, llvm::Instruction*) () code is like follows: //#include necessary header files int main(){

Hi, I want to use a function defined in c(++)-code from code generated by llvm. For this I use ExecutionEngine.addGlobalMapping(). I started with the JIT execution engine and everything worked, then I switched to the interpreter engine and it stopped working, but only if compiled on a Linux system. More precisely it works if I use llvm 3.8.1 + gcc (Linux) + JIT llvm 3.8.0 + mingw-gcc

Hello, I am attempting to use llvm casting and intrinsic functions to do basic operations on Value pointers. I have read the online documentation and relevant portions of the source code and wrote the following code to do a Float to Double cast and then a log operation- Value *castFP(Value *i, Type *ty) const { return b->CreateFPCast(i, ty, n); } \\b is an IRBuilder and TheModule is an

Hi All, LLVM has long needed a tutorial for people who are interested in using it to implement their favorite language and to demonstrate how to use the JIT. To help solve this, I've put together a little tutorial that runs through the implementation and extension of a toy language here: http://llvm.org/docs/tutorial/ At this point, the tutorial is feature complete, but might

I'm working through the Kaleidoscope tutorial through section 2.4, and I've encountered some problems: several minor bugs, and finally a bus error that has me stumped: ------- In the code listed in LLVM Tutorial section 2.2 Implementing a Parser and AST. Line 19 has a comma at the end of line that shouldn't be there Line 120 is missing a closing angle bracket. Line 120 should be
