Cross-Compile Tutroials, Getting Stuck

JBaumbach

Hi Everyone,

I have tried several tutorials on setting up cross-compiling for the Raspberry Pi, but ran into a brick wall every time. Here are links to two popular tutorials I have tried and a short log where things go south:

Can anyone help me figure this out and get QT5 up and cross-compiling on the Raspberry Pi?

I have Ubuntu running in a VM under Windows 7 and the latest Raspberry Pi. Ideally I would like to develop under Windows, but if I need a flavor of Linux, so be it. I am a .Net developer with limited Linux experience, so this has been quite the learning curve for me.

Thanks!

Hi,

bq. Connecting to swap.tsmt.eu (swap.tsmt.eu)|5.39.84.121|:80… connected.

The Toolchain is not present at the location and hence the error and so not downloaded. Check the size of it.
When you run the tar extract command, it will obviously fail.

Try this "link":http://sourceforge.net/projects/rfidmonitor/files/crosscompilation-resources/gcc-4.7-linaro-rpi-gnueabihf.tbz/download for the toolchain. I checked the md5sum of this tar file with the one i had downloaded earlier from http://swap.tsmt.eu and it matches so they are identical.

Hi Joe,

try this
wget https://www.dropbox.com/s/sl919ly0q79m1e6/gcc-4.7-linaro-rpi-gnueabihf.tbz

It should work

You can also use the toolchain provided by raspberry pi foundation https://github.com/raspberrypi/tools.

I have managed to cross compile qt5.4 in release, compiling in debug will fail with the following error : http://pastebin.com/M5KrCN1p

Then if i use the release build, any project using QWebView will segfault (ie browser sample).

Anyone experienced this ?
