Bug 49655

Summary:	[Qt] using compiler flag /EHsc breaks build webkit 2.0
Product:	WebKit	Reporter:	bleukousuke
Component:	WebKit Qt	Assignee:	Nobody <webkit-unassigned>
Status:	RESOLVED INVALID
Severity:	Minor	CC:	benjamin, jturcotte

Description bleukousuke 2010-11-17 04:28:01 PST

I stumbled on this when compiling qt4.7 with msvc9
earlier versions use /GX as standard

How to reproduce:
compiling qtwebkit 2.0 trunk (seperate not qt4.7) without /EHsc 
compiling qtwebkit 2.0 trunk with environment variable CL= /EHsc

/EHsc is standard in msvc9
 and optional in msvc8

the code warning in the end of qtwebkit2.0 claims something in the code isnt usable with /EHsc
and a macro redefinition of _HAS_TR1 is also solved when not using /EHsc

but this is not to be taken literally

because if you use msvc10 it should use /EHsc as standard
I had it also as an environment variable (by mistake)
when this is the case, the build fails
but when I remove the environment variable
it works like a charm

Funny enough
qt4.7 has the same problem as msvc2008
with the environment variable

and msvc2010 without the environment variable

I'll post some logs as a follow-up later

Please follow this to report bugs on QtWebKit: http://trac.webkit.org/wiki/QtWebKitBugs

I do not understand any of this, maybe Jocelyn will know :)
