Hi there,

I have UVLayout 2.08 installation problem on Linux (Centos 64bit).

By following your instruction (http://www.uvlayout.com/index.php?option=com_wrapper&Itemid=110), I successfully passed these two commands:
export HEADUS_HOME=/usr/local/uvlayout-demo
export PATH=$HEADUS_HOME/bin:$PATH

Then when I tried to use the following command:
mkdir -p $HEADUS_HOME

It shows: mkdir: missing operand

Could you let me know what is happening at this step?

The error would imply that the "export" command isn't working, because the $HEADUS_HOME variable has nothing in it. You have to run all of those commands in the same shell window.

For libXm, read this ...

For libgomp, you'll need to use the package manager on your system to install that. There may be other missing libraries though, but you'll find that out once libgomp is installed and you try and run uvlayout again.

You may want to use a wrapper script too to run uvlayout. Info on that can be found here ...

Getting UVLayout to work on Linux is more complicated because there's lots of different distos, and which libraries are loaded by default can vary. If you just want to see how UVLayout works, using the Win or Mac Demo version would be easier, and then you can tackle the Linux installation if you want to take it any further.

Check the permissions of the files in $HEADUS_HOME/bin - make sure that they're readable as well as executable:

I figured it out. Now, it works on Linux. However, when I type uvlayout in terminal that opens uvlayout flawlessly but terminal then shows this (please see attached image).

If someone could teach me how to install those missing fonts so I can make uvlayout working perfectly on Centos 64.

[headus]

On some distos those fonts are in the "xfonts-75dpi" package. I just did a google search for centos and it came up with the "xorg-x11-fonts-75dpi" package, so maybe try that too.

Sorry I didn't get back - got a bit busy over the weekend.

Yes, the different distros seem to shuffle the fonts all over the place{1}; I've found that the substituted fonts work quite adequately though, so, although the warnings list in the terminal window, there is no problem with the actual running of UVLayout.

Geoff

{1} Worse still - different versions of one distro seem to move the fonts between packages.

"so, although the warnings list in the terminal window, there is no problem with the actual running of UVLayout."

Thanks for the tips Geoff! Actually, because its X11, you can configure UVLayout to use whatever fonts you want via a .Xdefaults file. You need to add something like the following ...

"I solved the fonts issue. Now, uvlayout run nicely on Centos 64."

Thanks for the good news!

"until I change the view windows size it disappears until I finish the changes of window size and release my mouse. The loaded model then shows up again. "

Yes, that's on purpose. On slower or older systems, disabling the mesh draw helps to make the window resizing a lot smoother. Especially on systems without a dedicated graphics card, doing both at once (resizing and redrawing) was too jerky.

"Also when I click different section buttons (for instance,Edit, Optimize and so on) after using them and close the option windows by click "X" button on the upper right corner, the loaded mesh quickly disappears and then shows up again. "

The mesh is supposed to disappear when you move the floating panel around (i.e. left mouse drag blue title bar) for the same reason as above. I've never noticed the mesh flicking off though with the panel close, but just checked and it is doing it here too. I expect its getting an X event there briefly that makes UVLayout think the the panel is about to move. The mesh blanking only happens though if you have the floating panel overlapping the 3D window ... I personally position my floating panels off to the side so they dont overlap.
