Thanks Venu! This has been a very helpful work-around.

However, I did recently get to the bottom of this, at least on my system. So if you’ve installed it to a location with “no” spaces, and still encounter this error, then this is likely to help:

I had to put m4.exe in the same directory as my .y grammar to get bison to work. It wasn’t working in the bin directory with Bison. Don’t know why.

Installing Bison’s PATH entry as C:\Progra~1\GnuWin32\bin seems to work for me and removes the need to copy m4.exe locally. Installing bison to c:\gnuwin32 should also work. The problem as wlad noted is the space in the path to m4.exe. Oh, and I also had to hunt down an older version of Bison that I’d installed elsewhere and didn’t support the –defines parameter. Running which m4.exe in a cmd prompt to check you are getting what you expect is a good idea.

just for completeness, having bison.exe and m4.exe in C:\Gnuwin32\bin (and nowhere else in PATH) works for me.

I’ve seen that with bison installed into default path (with spaces C:\Program Files\…). The bug was apparent in bison 2.4. I filed a bug some half year ago, still no reply). Also QT folks document it here http://trac.webkit.org/wiki/BuildingQtOnWindows. Meanwhile you might want to check which m4.exe bison is looking for, using procmon.

Thanks Venu; since an year+ and to build and extend our storage engine, we used to build yacc on Linux and copy the files to Windows; it’s a painful process

I just tried this on Windows 7 and it works
