[SOLVED] QT 4.8* VS2010 /MT & /MTd

? Offline

Hi everyone!
My should be destributed with InnoSetup installation for normal users(without any admin rights), and Qt needs vcredist to be installed wich needs admin rights to be installed... so I've decided to compile Qt(and my App itself) with /MT flag instead of /MD...
I've simply changed qmake.conf in mkspecs/win32-msvc2010:
@QMAKE_CFLAGS_RELEASE = -O2 -MT
QMAKE_CFLAGS_DEBUG = -Zi -MTd
@

Compilation was done flawlessly... without any errors....

BUT, using QtWebKit brings me following error:
@Invalid Address specified to RtlFreeHeap@

Is that a known BUG? Is it WebKit or Qt BUG?
And is it possible to get rid of it?

Hi,

if I remember correctly, "/MT links the c-runtime statically.":http://msdn.microsoft.com/en-us/library/2kzt1wy3(v=vs.80).aspx This means, each library and the executable have own versions of the c-runtime.

Statical linkage might result in different heaps you are using which will exactly throw out this error.

Oh, right! I've totally forget about that!!! Allocating heap in one dll with own crt and trying to free it in another with it own crt can't be done! Thank you!

Hello All,
I am new QT and I have been trying to build a static build of QT for MSVC2013. But the Nmake fails with the following types of linker errors. Appreciate your help in resolving these :

I have configured the conf file as advised in the post as follows
QMAKE_CFLAGS_RELEASE = -O2 -MT
QMAKE_CFLAGS_DEBUG = -Zi -MTd

and before running nmake set the configuration as follows :
configure -debug-and-release -opensource -static -opengl desktop -mp -nomake examples -platform win32-msvc2013

Appreciate your response.

thanks.
