The TC10 and TC11 repositories now have X86 and X86_64 versions of gpicview.tcz.
If there are any Raspberry Pi users running a GUI who are interested in this, here are the build instructions:
# First make a working directory
mkdir gpicview
cd gpicview
wget http://tinycorelinux.net/10.x/x86/tcz/src/gpicview/build_gpicview.sh
wget http://tinycorelinux.net/10.x/x86/tcz/src/gpicview/gpicview-0.2.5.tar.xz
chmod 775 build_gpicview.sh
./build_gpicview.sh
The build_gpicview.sh script will download and install extensions that are required to build this package.
The build_gpicview.sh script will not alter your onboot.lst file.
When it completes (1 or 2 minutes):
The current directory will contain gpicview-armv.tar.gz.bfe which you can submit to the piCore repository if you wish.
The package directory will contain a gpicview and a gpicview-locale extension.
Copy gpicview.tcz, gpicview.tcz.dep, and gpicview.tcz.md5.txt to your tce/optional directory. Copy the locale files too if needed.
Then:
tce-load -i gpicview
A new icon will appear and will display ImageViewer when you hover over it.
