Bug #: 51699
Summary: Clang refuses to compile ext/rope citing scope
resolution issues
Classification: Unclassified
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: minor
Priority: P3
Component: libstdc++
AssignedTo: [email protected]
ReportedBy: [email protected]
When using clang to compile an existing program, clang refuses to compile the
ext/rope header files. One of the errors given is below.
ropeimpl.h:433:2: error: use of undeclared identifier '_Data_allocate'
_Data_allocate(_S_rounded_up_size(__old_len + __len));
g++ will compile this okay but the clang authors claim this code is invalid,
http://llvm.org/bugs/show_bug.cgi?id=6454. Below are the 7 changes to the two
files that allowed a successful compile. Line numbers may not be exact.
In ropeimpl.h
