Bug 120915 – "ISO C++ forbids taking the address of a bound member function" when building jsc on gtk

• Status: UNCONFIRMED
• Component: JavaScriptCore

[Alon Zakai]

Running Tools/Scripts/build-jsc --gtk on latest webkit svn gives me output that ends with


  CXX    Source/JavaScriptCore/llint/Programs_LLIntOffsetsExtractor-LLIntOffsetsExtractor.o
In file included from ../../Source/JavaScriptCore/llint/LLIntOffsetsExtractor.cpp:72:0:

This is with gcc-4.7.2 on Ubuntu 12.10.

What revision are you using?
Can you try again on a clean build?

I'm not experiencing any problems when using GCC 4.7.3 on Ubuntu 13.04. Perhaps the generated LLIntDesiredOffsets.h header is corrupted.

This was on svn rev 155226 (from last friday). I updated to 155356 now. Same issue. I have no local changes, svn diff shows nothing.

But I found that when I delete that header file, then it builds ok. So I guess the only issue is the build system did not automatically regenerate it or something like that?
