How to build QtBase 5.0.2 on Windows XP SP3 using msvc2005
I didn't find enough information on the web, so I figured it out myself how to successfully build the DLLs of QtBase 5.0.2 on Windows XP SP3 using msvc2005. Here's the summary on how I finally succeeded.
From here you can download the modified files: http://cara.nmr-software.org/download/Qt5.0.2_WinXP_SP3_modified_files.zip
Follow these steps:
Change mkspecs\win32-msvc2005\qmake.conf: add -D_WIN32_WINNT=0x0503 -DWINVER=0x0503 -D__RPC__deref_out to QMAKE_CFLAGS; add /FORCE to QMAKE_LFLAGS
I used the following options to run configure: -opensource -platform win32-msvc2005 -no-opengl -no-openssl
manually add /FORCE to the Makefile.* of qmake (this doesn't seem to automatically happen, even with the mkspecs modification of point 1).
Replace src\plugins\platforms\windows\qtwindows_additional.h with the version provided (modifications are tagged as ROCHUS)
Replace src\plugins\platforms\windows\qwindowsdialoghelpers.cpp with the version provided (modifications are tagged as ROCHUS)
Replace src\widgets\util\qsystemtrayicon_win.cpp with the version provided (modifications are tagged as ROCHUS)
Like this I was able to build the DLLs; and then to compile and run some examples.
I also noticed that nmake confclean does not delete the the Makefiles, and they aren't recreated by the next run of configure; that's why the changes to mkspecs are not reflected; I therefore had to manually delete Makefile, Makefile.Debug and Makefile.Release (didn't touch Makefiles in the thirdparty folder though).
Hope this helps. Comments are welcome.
