Hep with building QT 4.8 with webkit

Hello

After being stuck with my kobo's built-in browser, i decided to try to make my own.

I decided to follow this tutorial on building Qt 4.8.5:

But when I followed this tutorial and removed the --no-webkit option on ./configure, it would fail to compile.

So, I decided to follow this tutorial as well as the previous one.


My environment is Lubuntu 18.04 32bit, and the tutorials work right until I need to compile QtWebKit with:
They failed to find zlib.h, png.h and jpeglib.h
I just sort of copied the header files in to the directories that caused problems, but now at the very end of the build, it fails to compile with these errors:

~/gcc-linaro-arm-linux-gnueabihf-4.8-2013.04-20130417_linux/arm-linux-gnueabihf/bin/ld: cannot find -lz
~/gcc-linaro-arm-linux-gnueabihf-4.8-2013.04-20130417_linux/arm-linux-gnueabihf/bin/ld: cannot find -lpng
~/gcc-linaro-arm-linux-gnueabihf-4.8-2013.04-20130417_linux/arm-linux-gnueabihf/bin/ld: cannot find -ljpeg

I was wondering if anybody could help me with my predicament.
I have a in progress tutorial on github which has the steps to reproduce the problem here.

Thanks in advance!
