Qt 4.8, Visual Studio 2013 compiling error

Solution 1

To fix 'round' and 'roundf' errors replace (lines 103 and 110):

static double round(double num)
static float roundf(float num)

with:

static inline double round(double num)
static inline float roundf(float num)

To fix 'signbit' error enclose it with following macro (line 128):

#if _MSC_VER < 1800
inline bool signbit(double num) { return _copysign(1.0, num) < 0; }
#endif

Solution 2

Use the official patch for VS 2013 compatibility.

Solution 3

Have you run "vcvars32.bat" before compiling? It seems the environment variables of VC++ are not appropriately set.

See http://msdn.microsoft.com/en-us/library/f2ccy3wt.aspx for informations about the environment of VC++.

Solution 4

Your problem is that you do not use Visual Studio 2012 but 2013. VS 2012 is VS11 while VS 2013 is VS12 and your path "C:\Program Files (x86)\Microsoft Visual Studio 12.0" belongs to VS 2013.

The core problem however is that VS 2013 is C99 compliant which causes problems in the V8 engine and javascriptcore.

There is currently no solution but manual patching.

Solution 5

The two patches proposed above were not enough. In my case, after applying them to Qt 4.8.5 I got another error:

I tested both patches from JPaget and Zdenik and they don't work in Qt 4.8.6. This is the only working answer.

Since the gitorious site with patches is offline for days (migrating stuff), can someone please send me the patched file for /src/3rdparty/**webkit**/Source/JavaScriptCore/wtf/HashSet.h‌, since this bug is still not fixed in qt 4.8.6 (allthough /src/3rdparty/**javascriptcore**/JavaScriptCore/wtf/HashSet.‌h compiles).
