Bison.exe I/O error building Qt5.2 on Windows

pyl0420

Hi:

I am doing a shadow build with Qt5.2 on Windows, but I got some bison.exe I/O error. Wondering whether anybody has seen similar issues or has any suggestion what might go wrong.

Thanks in advance.

Here is what I did:
@
unzip source to L:\qt-everywhere-enterprise-src-5.2.0
In VS2010 x64 command prompt
mkdir qt5_src_build
cd qt5_src_build
setup dependencies like python, icu, zlib
SET PATH=%PATH%;L:\qt-everywhere-enterprise-src-5.2.0\gnuwin32\bin
SET CL=/MP

@
L:\qt-everywhere-enterprise-src-5.2.0\configure -prefix L:\qt5_src_build -commercial -nomake tests -debug -confirm-license -opengl desktop
nmake
@

Here is the error I got

Looks like the problem is I have another version of m4 in my path. Put the "L:\qt-everywhere-enterprise-src-5.2.0\gnuwin32\bin" before all the system path will solve the problem
