1112043 - Compilation problem with gcc 4.6: undefined reference to 'mozilla::dom::indexedDB::LoggingString::kCloseBracket'

Status: RESOLVED FIXED

(Core :: DOM: Core & HTML, defect)

Description

[Andrea Marchesini [:baku]]

I have problem linking with gcc 4.6 in debug builds:

ProfilerHelpers.h:167: error: undefined reference to 'mozilla::dom::indexedDB::LoggingString::kCloseBracket'
.... which may overflow at runtime; recompile with -fPIC

I found a similar issue in bug 906040 comment 6.

"I'm pretty sure the problem is this long-standing GCC quirk that it emits references to static const varaibles when they are used in a ternary operator (which you write "static const X = 1", this is a declaration and initialization, but not a *definition* which means, should a symbol ever be emitted for X, it'll be a link error, but mostly symbols never get emitted since the whole point is that they're inlined).  The usual fix is either to add a definition or take out the ternary operator."
