Hi, I am quite new to LLVM. I just compiled LLVM and clang on Ubuntu11.10 then followed the tutorial http://llvm.org/docs/DebuggingJITedCode.html clang -cc1 -O0 -g -emit-llvm showdebug.c where showdebug.c contains: #include<stdio.h> int main() { printf("hello\n"); return 0; } But I got Fatal error: 'stdio.h' file not found. However, clang showdebug.c has no

With the following call: llvm::ExecutionEngine* engine; llvm::EngineBuilder builder( module ); builder.setEngineKind( llvm::EngineKind::Either ); // it will use JIT if available builder.setUseMCJIT ( true ); engine = builder.create(); These calls are successful in windows. But when I try in Linux (Ubuntu), the create() function fails with the error message: Target does not support MC emission

Compiled the 3.0.0 version of the source code , then tried lli --use-mcjit irfile.txt On both windows and linux, I got: LLVM ERROR: Unknow object format. If I omit the -use-mcjit option, the command works well. It seems to me that something about MCJIT is broken in the 3.0.0 version. Also tried to initialize an ExecutionEngine from code, got errors like "Target does not support MC

I found the following problem when I try to debug "target does not support mc emission" in linux (the same code executes OK in windows): Below is a snippet extracted from this method, if (UseMCJIT && ExecutionEngine::MCJITCtor) { ExecutionEngine *EE = ExecutionEngine::MCJITCtor(M, ErrorStr, JMM, OptLevel,
