Fedora Users: Please read the comment #6 by GnuTux
=====
For Ubuntu or Ubuntu derived distributions:
We need to install "alien" to convert the package:


Then download MathMap Fedora package, "mathmap-1.3.5-2.fc15.i686.rpm" for Ubuntu 32 bits or "mathmap-1.3.5-2.fc15.x86_64.rpm" for Ubuntu 64 bits:
http://koji.fedoraproject.org/koji/buil ... dID=220694

Convert .rpm to .deb:
*Ubuntu 32 bits:

After that you should have a .deb package in the same path. Install .deb package.
That is all for Ubuntu 32 bits. You can find the filter in GIMP: Filters > Generic > MathMap

*Ubuntu 64 bits:

After that you should have a .deb package in the same path. Install .deb package.
Now we make the next symbolic link:


Now you can find the filter in GIMP: Filters > Generic > MathMap

This method should work whenever you have GIMP installed in /usr

For MathMap Extra Expressions see this thread:
viewtopic.php?f=9&t=4558

You can just unpack these packages and put into your local ~/.gimp-2.8 directory. Makes it a bit easier to 'hack' the '.mm' scripts than them having in root folders.

An easy way (non-command line) is with Peazip. Peazip will unpack both .deb and .rpm archives. A 2-stage process though. First unpack to a tar file (.cpio for an rpm) then unpack that to the folder structure.

Mathmap is not a particularly picky plugin, just has some annoying .devel requirements for compiling.

I have gone the other direction and use the binary from a deb package in an rpm based distro (PCLOS / Gimp 2.8.2). Still works.

MathMap not work with the plugin in your $HOME. Binaries must be installed on the system. So, I think using alien is still simpler for newbies rather than having to do it manually.
Anyway you can copy expressions you want in /home/YOUR_USER/.gimp-2.8/mathmap/expressions/

Just offering an alternative approach



And that is not exactly true, is it

Yes, I know. Thanks for that!. Just trying to make it as simple as possible for novice users.


Are you sure you do not have mathmap binary in /usr/bin (and symlink in /usr/lib/gimp/2.0/plug-ins/)?
Some time ago I had tried putting the binary in home and had not worked. I must have done something wrong then

Edit:
Well, I just leave the binary alone in home, and it works. So I take back about what I had said...

A couple of notes on Installing mathmap in Fedora.

The latest successful build of mathmap for Fedora is for Fedora 15.

However, mathmap can be installed in later releases of Fedora Linux. Ensure you install the correct version (32bit or 64bit) of libnoise & mathmap, matching your OS version.

Ensure that libnoise is installed, as it is a dependency of mathmap. libnoise is not included in the Fedora 18 repositories but you can manually install libnoise for F17 in Fedora 18 and Fedora 19.

Once you have libnoise installed, you can continue with the install of mathmap-1.3.5-2.fc15.

if all goes well, you'll find mathmap under Filters/Generic/Mathmap.

Note: mathmap-1.3.5-2.fc15 requires an older version of libpng as a dependency, which is should be installed alongside the newer version. I have not noticed any issues with doing this but it is possible there could be problems if you have previous modified libpng, (i.e. with the APNG plugin). Use libpng12 for Fedora 19 or libpng-compat for earlier versions of Fedora.

I am running Linux Mint 15 - Cinnamon with Gimp 2.8.6, and after doing the "alien" thing I installed the deb with "sudo dpkg -i mathmap-blah.deb". I started Gimp, and no Mathmap. I tried Rich's suggestion, but I found out later that the local stuff just doesn't work on my installation.

I then ran Gimp from a terminal and discovered Mathmap was failing because three libs were not installed. After I installed them (with Synaptic) Mathmap came right up and works just fine.

Thanks for this thread YAFU (and Rich). I have had trouble in the past trying to compile Mathmap, and I hope someone will benefit from my experience.

Hello.
Do you remember which were these packages? If you do not remember you can see in the history.log in "/var/log/apt/"
Thank you.

Hello YAFU,

It must have been only 2 libs that I installed. They were:

libgsl0ldbl
libjpeg62

Hope that helps.

Regards,
adam933

Please excuse my complete noobness on this but I must be doing something wrong.

Ok, I'm editing this post as I have got further than before but still no joy, I am including a text copy of my terminal output after running gimp, hopefully somebody will help me make sense of all this.

WOW! I can't believe this,
I installed libnoise for F17, (Tux's instructions)
and this: mathmap-1.3.5-2.fc15
Now I have Mathmap on Fedora 19
I thought I had to do all the make stuff so I was holding off on it.

woo hoo

mathmap is complaining that you don't have the following library installed: libgtksourceview2-2.0.so.0
mathmap: error while loading shared libraries: libgtksourceview-2.0.so.0: cannot open shared object file: No such file or directory

In Fedora, that library is provided by: gtksourceview2
See if you can install: gtksourceview2 from your Linux repositories.

I also noticed a few other issues GIMP is complaining about.

The following files are generating errors because they are in the resource folders. They should be moved out of these folders to avoid the warning messages.

Patterns folder
Artex.zip
Canvas-Covered.xcf

Pallettes folder
Picture-Frame.gpl.zip
Palette Pack 01.zip

Gradients folder
Crown Mouldings.zip
Gradient Pack 01.zip

GIMP is complaining that you have two versions of: MLBevelReflect in your plug-ins folder. It is saying that you have a copy in: /usr/lib/gimp/2.0/plug-ins/
You should probably remove that one (as root) and only keep one copy in your: /home/user/gimp-2.0/plug-ins/ folder/

There is an error in the script: Picture Frame.scm
Line 307: illegal function

There is also an error in: RMA-path-blend
image-type contains unrecognizable parts:'RGB*, GREY*'

You might want to update or remove those two scripts (or post them here and so we can check them out & fix)

GIMP is also looking for following but can't find it: settings-cleaner.ini
Config file /home/lee/.gimp-2.8/tool-options/settings-cleaner.ini not found

I don't know what settings-cleaner.ini is. Perhaps someone else knows.

Tux - Thanks for all your help, I now have mathmap running, although still showing these errors in gimp


(gimp:4475): Gimp-Widgets-CRITICAL **: gimp_device_info_set_device: assertion `(info->device == NULL && GDK_IS_DEVICE (device)) || (GDK_IS_DEVICE (info->device) && device == NULL)' failed

(gimp:4475): LibGimpBase-WARNING **: gimp: gimp_wire_read(): error

I have as far as I'm aware reinstalled the latest version of path blend.

Remembered this Script I had installed when I removed it the problems has gone with the cleaner error.

Glad I could help, he4rty. I see that you are already checking with RobA on the Path-Blend script warnings, which is what I was going to suggest.

Hi he4rty,

Just change the GREY* to GRAY*.
That will fix it.

Thanks I'll try that. It worked, Thanks.

END of install history because
NO CLUE ABOUT WHAT I CAN DO WITH MATHMAP...
but I know I "can" install it. (THANKU YAFU. You are a beacon of straightforward-ness.)
