Thank you.
I tried your suggestion on XCode on MacOS. But it still does not break for me.
I set a break point at:
Local<Script> Script::Compile(v8::Handle<String> source,
v8::ScriptOrigin* origin,
v8::ScriptData* script_data) {
ON_BAILOUT("v8::Script::Compile()", return Local<Script>());
LOG_API("Script::Compile");
ENTER_V8;
i::Handle<i::String> str = Utils::OpenHandle(*source);
i::Handle<i::Object> name_obj;
int line_offset = 0;
int column_offset = 0;
/* Set my break point in the line below */
if (origin != NULL) {
Here is how I set my breakpoint:
1. I open the build/all.xcodeproj
2. click open the test_shell.xcodeproj
3. click open the v8.xcodeproject
4. open api.cc
5. set breakpoint in the location I mentioned above
6. go to test_shell.xcodeproj and click 'Build and Go(Debug)'
7. load an url, (e.g. www.yahoo.com)
The site gets loaded, but the break point never breaks.
I appreciate if anyone can help me with this.
Thank you.
