Hi,
I am new to LLVM and Clang. I am trying to set up Clang on my system. I
am currently running it on Ubuntu 10.04 which is loaded on a VM.
After Installation I tried running a small code to check if it works
this is my code
#include <iostream>
#include <llvm/Support/raw_ostream.h>
#include <clang/Basic/Diagnostic.h>
#include <clang/Basic/TargetInfo.h>
#include <clang/Basic/FileManager.h>
#include <clang/Lex/Preprocessor.h>
#include <clang/Lex/HeaderSearch.h>
#include <clang/Frontend/TextDiagnosticPrinter.h>
#include <clang/Frontend/DiagnosticOptions.h>
using namespace clang;
int main()
{
llvm::raw_stdout_ostream ost;
DiagnosticOptions dops;
TextDiagnosticPrinter tdp(ost,dops);
return 0;
}
when I run this bit of code using
g++ tut1.cpp -g -fno-rtti `llvm-config --cxxflags --ldflags --libs`
-L/usr/local/lib -lclangBasic -lclangLex -lclangDriver -lclangFrontend
-lclangParse -lclangAST -lclangSema -lclangAnalysis
this is the output that I get
fla@ubuntu:~/Desktop/Clang$ g++ tut1.cpp -g -fno-rtti `llvm-config
--cxxflags --ldflags --libs` -L/usr/local/lib -lclangBasic -lclangLex
-lclangDriver -lclangFrontend -lclangParse -lclangAST -lclangSema
-lclangAnalysis

Their seems to definitely be some issue regarding linking of the libraries
and the steps used for installation were
svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm
cd llvm/tools
svn co http://llvm.org/svn/llvm-project/cfe/trunk clang
cd .. (back to llvm)
./configure
make
(tried make install also)
Could someone help me out with what could be the root cause of this
problem and the possible solution.
Thanks,
Shashank
