[LLVMdev] Question about linker error
Hello all,
When extending the tutorial to support global variables I'm getting
the following linker error:
glob.o:glob.cpp:(.text+0x12241): undefined reference to `vtable for
GlobalExprAST'
collect2: ld returned 1 exit status
GlobalExprAST class is:
/// GlobalExprAST - Expression class for globals
class GlobalExprAST : public ExprAST {
std::string Name;
ExprAST *Init;

[LLVMdev] conversion from 'const llvm::Value*' to 'llvm::Constant*'
Oh, I thought that after "codegening" cos(0) would get me double 1.0
(assigment is working for anything like: global a = 1/3 + 2 /3 for
example) What would be the best way to make assigments involving
functions, like global a = cos(0);
without getting the assertion arising from InitVal =
cast<Constant>(Init->Codegen()); ?
I made some changes and now my code basically works,

[LLVMdev] conversion from 'const llvm::Value*' to 'llvm::Constant*'
Hi
Apolagize if this newbie question has some obvious answer. When running
something like
...
ExprAST *Init = GlobalNames[i].second;
const Value *InitVal;
InitVal = Init->Codegen();
GlobalVariable * globvar = new GlobalVariable(*TheModule,
InitVal->getType(), false, llvm::GlobalValue::ExternalLinkage, InitVal,
Twine(GlobalName));
...
I'm getting the following error

[LLVMdev] Emitting LLVM IR for control flow
Hi
I'm following the excellent Kaleidoscope tutorial to learn how to build an
interpreter using LLVM. Apologize if this list is not the best place to post
beginner's questions. In Kaleidoscope 2.7 when I run
def binary : 1 (x y) y;
def testfor (x)
(for c = 1, c<2 in
x = x +1 ) :
x;
testfor(1)
unexpectadly get 3.000000 instead of 2.000000. This happens, I believe,
because the
