2009-03-21 17:25:37 Cannot find qt

Hello, I have what I hope is a simple question -- where do I find QT !?

My understanding is that it is integrated into the uClinux, and that there should be a 'libqt' directory under the libs directory in the build, but I cannot find it when browsing with Subversion. I cannot find a qt-embedded directory, either.

I have checked out uClinux-dist-2008R1.5-RC3 and when I run 'make menuconfig' I do not see any options for building qt (and I can't find a libqt or qt-embedded directory in there, either).

I am now in the process of checking out the trunk, to see if qt will appear in the current version when I run 'make menuconfig'

I would be greatly appreciate any help that anyone could give me on this one!

Thanks

Greg

It's in trunk - not in the older releases.

Hi Robin -- thanks for that.

The checkout that I did of the current trunk results in compilation errors during the QT build (included below). Does anyone know of a trunk revision number where qt will build? If so, then I can check out that particular revision and use "make menuconfig" to create Makefiles that will build QT....

Greg:

Trunk uClinux-dist requires trunk toolchain. Did you check out and build a toolchain - like it says is required in the docs I sent before?

HI Robin -- I am checking out the toolchain right now. I just wanted to thank you for sharing your expertise -- I apoligize if I missed your earlier toolchain instructions. Your help is very valuable and very much appreciated by this weekend warrior!

Following the instructions that Robin pointed me to, I got trunk versions of the kernel, toolchain, and u-boot. The toolchain build went very smoothly. However, I cannot 'make' uClinux distribution.

The tail end of my 'make' output is shown here -- I am not sure exactly what the error is, but the make process ends before qt is built or installed into the staging area. . . . my quest for a build of QT for the blackfin continues, and any help would be very much appreciated!

that doesnt contain an actual error. run `make single` to see the real error.
