clang - LLVM assertion error -
i'm trying use llvm/clang api compile source code llvm ir.
clang_ir.cpp:
#include <iostream> #include <clang/driver/compilation.h> #include <clang/driver/driver.h> #include <clang/frontend/textdiagnosticprinter.h> #include <llvm/support/host.h> #include <llvm/support/program.h> #include <llvm/support/raw_ostream.h> using namespace std; using namespace clang; using namespace clang::driver; int main(int argc, char** argv) { cout << "starting ----" << std::endl; // [clang -s -emit-llvm ./test/hello_world.cpp] // arguments pass clang driver: string clangpath = "clang"; string inputpath = "./test/hello_world.cpp"; string outputpath = "hello_world.ll"; vector<const char *> args; args.push_back(clangpath.c_str()); args.push_back("-s"); args.push_back("-emit-llvm"); args.push_back(inputpath.c_str()); // clang driver needs diagnosticsengine can report problems clang::diagnosticoptions *options = new clang::diagnosticoptions(); //clang::textdiagnosticprinter *diagclient = new clang::textdiagnosticprinter(llvm::errs(), options); clang::intrusiverefcntptr<clang::diagnosticids> diagid(new clang::diagnosticids()); clang::diagnosticsengine diags(diagid, options); cout << "making driver" << endl; // create clang driver clang::driver::driver thedriver(args[0], llvm::sys::getdefaulttargettriple(), outputpath, diags); // c++ code //thedriver.ccciscxx = true; cout << "making compilation" << endl; // create set of actions perform clang::owningptr<clang::driver::compilation> compilation(thedriver.buildcompilation(args)); cout << "printing actions:" << endl; // print set of actions thedriver.printactions(*compilation); std::cout << "done ----" << std::endl; // carry out actions int res = 0; smallvector<std::pair<int, const command *>, 4> failingcommands; if (compilation) res = thedriver.executecompilation(*compilation, failingcommands); // report problems /* if (res < 0) thedriver.generatecompilationdiagnostics(*compilation, failingcommands); */ (smallvectorimpl< std::pair<int, const command *> >::iterator = failingcommands.begin(), ie = failingcommands.end(); != ie; ++it) { int commandres = it->first; const command *failingcommand = it->second; if (!res) res = commandres; // if result status < 0, driver command signalled error. // if result status 70, driver command reported fatal error. // in these cases, generate additional diagnostic information if possible. if (commandres < 0 || commandres == 70) { thedriver.generatecompilationdiagnostics(*compilation, failingcommand); break; } } return res; } successfully built command-line:

while running i'm getting assertion error:
mba-anton:build asmirnov$ ./clang_ir starting ---- making driver making compilation assertion failed: (getclient() && "diagnosticclient not set!"), function emitcurrentdiagnostic, file /users/asmirnov/documents/dev/src/llvm_34/tools/clang/lib/basic/diagnostic.cpp, line 391. abort trap: 6 mba-anton:build asmirnov$ what can reason?
it pretty tells problem is. diagnosticclient wasn't set. diagnosticengine requires diagnosticclient- callback when diagnostic occurs.
frankly, clang c++ api full of annoying shit this. it's ask take reference or pointer client in engine constructor. have used fixing each assertion failure comes up.
