Errors with ltib when trying to include QT embedded

blsousan — Thu, 28 Jun 2012 21:56:31 GMT

So I am trying to add QT embedded to my root file system using ltib. With the other packages I simply select them, run ltib, and no problems (it adds them to the rootfs). However, when I tried the QT embedded it had errors in finding the package at the www.bitshrine.org. (qt-everywhere-opensource-src-4.6.0.tar.gz). I manually checked and sure enough its gone.

After some googling - I saw where one said that I could simply go get this package myself and put it in the /opt/freescale/pkgs directory and re-run tlib. I did this but then I get a lot of errors with it can find the libraries (like libpng, etc...). I verified the libraries do in fact exist. It also gives a warning of:

"Build path taken because: directory build, no prebuilt rpm," and

"You have not explicitly asked to use pkg-config and are cross-compiling."

Do I need to specify in the spec file or other? where the libraries live - or is there a better way of doing this?

Thanks,

Bills

Thanks. I tried these (basically building it outside of ltib) and still get a linker error where it can not find the libpng library. The thing is when is starts, I get this warning:

You have asked to use pkg-config and are cross-compiling.
Please make sure you have a correctly set-up pkg-config
environment!

Warning: PKG_CONFIG_PATH has not been set. This could mean
the host compiler's .pc files will be used. This is probably
not what you want.

I got it to work by adding the -lpng option the build in the spec file. Wow it is a pain to build qt for the imx.

The link (http://imxcommunity.org/group/imxqt/forum/topics/building-qt-for-imx5x?xg_source=activity) does not work for me. Is there another link I can use?
