Hi Simon, thanks for your help. I am running the script on macOS Mojave 10.14 and I'm pretty sure I have the lldb python bindings installed. Or otherwise it should fail when importing them at the beginning of the script, right? From what I understood by reading the script's code, it is directly calling into the lldb binding to dump the class layout, and it's failing inside.
As I've said before, the error it gives me implies that the provided framework/class pair has not been found in the image, even though I am sure that the pair is valid and found in the image (e.g. JSC::JSString). ________________________________ Da: simon.fra...@apple.com <simon.fra...@apple.com> per conto di Simon Fraser <simon.fra...@apple.com> Inviato: lunedì 5 novembre 2018 14:17 A: Frank Jaeger Cc: webkit-dev@lists.webkit.org Oggetto: Re: [webkit-dev] dump-class-layout script not working Dump-class-layout uses the lldb python bindings. Maybe those are not available on your platform? I think we’ve only ever tried it on macOS. What platform are you trying on?

First of all I'm really sorry if this is the wrong mailing list to post to, webkit-help would have probably been better but it doesn't seem very active. I run into some problems while trying to use the dump-class-layout script (found in Tools/Scripts/). I built WebKit using the build-webkit script with the --debug flag. After building, I tried to run the dump-class-layout script with the following arguments: ./Tools/Scripts/dump-class-layout --architecture=x86_64 -c Debug JavaScriptCore JSString I also tried different frameworks and classes. The script always fails telling me that "no type matches x in y" where x is the class name I used in the run and y is the framework name. Why is this happening? The script is correctly finding the built and symbolicated framework image, so why is it not working properly? Thanks in advance. _______________________________________________ webkit-dev mailing list webkit-dev@lists.webkit.org<mailto:webkit-dev@lists.webkit.org> https://lists.webkit.org/mailman/listinfo/webkit-dev
