Can't build Qt in Windows from source, Perl installed but still can't find headers

[Matt Phillips]

I'm using Cygwin on Windows 7, 64-bit. I downloaded the 4.8.3. source and followed the instructions "here ":http://qt-project.org/doc/qt-4.8/install-win.html, putting <qtdir>/bin in PATH along with the path to my chosen compiler. Configure fails immediately,

Discussions "here ":http://qt-project.org/forums/viewthread/5360 and "here":http://stackoverflow.com/questions/2084766/how-to-build-latest-qt-from-git-repository-on-windows identify the problem as being with Perl; however Perl is on my system and on the path. To be sure I went and downloaded/installed ActivePerl, after which I added Perl64/bin to the path. Same result.

[QUOTE]$ whereis perl

perl: /bin/perl.exe /usr/bin/perl.exe /usr/share/perl
/cygdrive/c/Perl64/bin/perl.exe /cygdrive/c/Perl64/bin/perl516.dll

$ echo $PATH

/cygdrive/c/Perl64/bin:/cygdrive/c/gcc/bin:/bin: ...
/cygdrive/c/Qt/4.8.3/bin [/QUOTE]

Would very much appreciate some help out with this. Clearly it's some kind of paths issue but I don't know what else to include at this point
