NMAKE : fatal error U1077: 'cd' :return code '0x2' cl.exe

Question

I'm trying to compile QCAD (an open source CAD application which relies on Qt) from the source so I can build it for msvs2008. I've been following the instructions given here: http://www.qcad.org/en/component/content/article/78-qcad/111-qcad-compilation-from-sources.

I've managed to successfully configure and compile Qt 4.8.5 and I set my environment variable PATH. I created a new environment variable QMAKESPEC and set the value to win-32-msvc2008. I completed the configuration of QCAD without any problems. However, about 30 min into the compilation I've run into the following error: NMAKE : fatal error U1077: 'cd' :return code '0x2'. I've seen similar errors reported for the compilation of Qt, however, I had no problem there. Is there anyone who has any idea what may be wrong? Thanks in advance.

It took a while but I've solved the problem. The file QtScriptShell_QWebPluginFactory.cpp contained a couple of lines decalring empty arrays:

static const QWebPluginFactory::Extension qtscript_QWebPluginFactory_Extension_values[] = {};
static const char * const qtscript_QWebPluginFactory_Extension_keys[] = {};

Though this is acceptable for C99, the Visual Studio C++ compiler won't accept empty arrays. So I simply added a non-zero size and the error disappeared.

static const QWebPluginFactory::Extension qtscript_QWebPluginFactory_Extension_values[1];
static const char * const qtscript_QWebPluginFactory_Extension_keys[1];
