Process not launching in example python script from lldb documentation

Subprojects LLDB

Hello,
Looks like last python example from http://lldb.llvm.org/python-reference.html is not working (using the lldb.py module in python). For some reason process is not launching in debugger.

I’m using clang++ and lldb from llvm trunk on Ubuntu 14.04 x64:

$ cat main.cpp
#include
int main (int argc, char **argv) {
std::cout << “Hello world \n”;
return 0;
}

$ clang++ -g main.cpp
$ ./python_example.py

Creating a target for ‘./a.out’
SBBreakpoint: id = 1, name = ‘main’, module = a.out, locations = 1
SBProcess: pid = 0, state = launching, threads = 0, executable = a.out

Process state is “launching”, but should be “eStateStopped” according to comments in source code.

Ok, I’ve figured it out: looks like install script was broken:

I build and install lldb using:
cmake …/llvm

make
make DESTDIR=$CLANG_INSTALL_PATH install

LLDB installed this way is not working.

But when I use python package directly from build_dir//lib/python2.7/site-packages it is working fine:

$ ./python_example.py

Creating a target for ‘./a.out’
SBBreakpoint: id = 1, name = ‘main’, module = a.out, locations = 1
SBProcess: pid = 5853, state = stopped, threads = 1, executable = a.out
thread #1: tid = 5853, 0x000000000040081a a.out`main(argc=1, argv=0x00007ffed229c738) at main.cpp:3, name = ‘a.out’, stop reason = breakpoint 1.1
