In Qt Creator, when I create a new Unit Test project it will not build successfully if the full path to the project contains a space.

I've tracked the bug down to the makefile produced by qmake. The makefile contains a line near the top like:

DEFINES = -DUNICODE -DWIN32 -DSRCDIR=\"C:/Users/Smith/Qt Projects/Unit_Tests/\" -DQT_QML_DEBUG -DQT_DECLARATIVE_DEBUG -DQT_TESTLIB_LIB -DQT_CORE_LIB -DQT_TESTCASE_BUILDDIR=\"C:/Users/Smith/Qt Projects/Debug_Unit_Tests\"

The quotes in the values for SRCDIR and QT_TESTCASE_BUILDDIR are escaped with backslashes. If I delete the backslashes from Makefile.Debug, then the project will build successfully.

Obviously, I don't want to have manually delete the backslashes every time. I'd also like to avoid a custom build step that removes the backslashes. Because qmake has so many options, I was hoping there was something I could just put in the .pro file that will fix this.

I tried something like DEFINES -= QT_TESTCASE_BUILDDIR. That doesn't work however because QT_TESTCASE_BUILDDIR is not yet defined. testlib apparently adds its own definitions later.

I am using:

  • Visual Studio 2010 SP 1
  • Qt 5.0.2
  • Qt Creator 2.7.0
  • Windows 7

What's the simplest way to get rid of the backslashes?

Edit: This also happens OSX.

The definitions added by testlib are in testlib_defines.prf which is in:

C:\Qt\Qt5.0.2\5.0.2\msvc2010\mkspecs\features

Change...

DEFINES += QT_TESTCASE_BUILDDIR=\\\"$$OUT_PWD\\\"

...to...

DEFINES += QT_TESTCASE_BUILDDIR=\"$$OUT_PWD\"

The other part is easy. The extra backslashes for SRCDIR come from the .pro file itself. Change...

DEFINES += SRCDIR=\\\"$$PWD/\\\"

...to...

DEFINES += SRCDIR=\"$$PWD/\"

Every time you install a new version of Qt, you'll have to edit the .prf file but that's better than having to edit the makefile every time qmake runs.

  • This is probably obvious, but once you've changed the .prf file, you'll have to explicitly run qmake again for QtCreator to see the updated QT_TESTCASE_BUILDDIR. – yagni Apr 08 '14 at 16:28
