[cfe-dev] CFG::dump in clang

[Surinder J]

I want to obtain a dump of CFG for a simple foo program

#include <stdio.h>
int main() {
  printf("Hello, World!\n");
}
I have tried the command

clang -cfg-dump foo.c

It gives a warning and ignores -cfg-dump option.

Also, if it is unable to link edit the program.  when I give the command

clang foo.c

It gives an error

/usr/bin/ld: crtbegin.o: No such file: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see
invocation)

Running with -v option gives the error

/usr/bin/ld: crtbegin.o: No such file: No such file or directory
clang: error: linker command failed with exit code 1 (use -v to see
invocation)
Any help to dump cfg would be appreciated.
