[LLVMdev] 回复： Dose I need to build llvm-gcc front-end from source to resolve this error?

[Bill Wendling]

Hi Sheng Wang,

I don't think so. This looks like it's not finding the correct  
headers, which isn't a problem in the llvm-gcc code itself. To  
determine what's going on, use the -v flag to see where it's trying to  
find the hearders. You may have to specify additional search  
directories on the command line. Especially if llvm-c++ isn't  
installed in /usr/bin.
