Hi,

I just would like to install Gmsh tool from the source code on Ubuntu and having some issue with it. I have downloaded Gmsh 3.0.4 from the following link http://gmsh.info/src/ and when I followed the instructions as below, I was not able to install it. I have Cmake installed in my system.

  (Note that "make install/fast" allows you to install only the target that you
  just built, i.e. "lib", and will not trigger the recompilation of the default
  target "gmsh".)

* To see a detailed compilation log use

    make VERBOSE=1


Build Gmsh using CMake's graphical user interface
-------------------------------------------------

* Launch CMake and fill-in the two top input fields (telling where the Gmsh
  source directory is located and where you want the Gmsh binary to be created).

* Click on "Add entry" and define the variable CMAKE_PREFIX_PATH, of type
  "PATH", pointing to the location(s) of any external package(s) (FLTK,
  BLAS/LAPACK, etc.) installed in non-standard directories.

* Click on "Configure" and choose your compiler.

* Optionally change some configuration options (re-run "Configure" every time
  you change some options).

* Once you are happy with all the configuration options, click on "Generate".

* Go to the build directory and build Gmsh using your chosen compiler.

Did anyone install Gmsh from the source could provide some help. I am using Ubuntu 14.04.

Thanks for the help.

Hi,

The installation on Ubuntu requires the following steps;

1- Extract the file.
2- Open the terminal and locate where you extracted Gmsh.
3- type in the terminal cmake CMakeLists and wait till the installation finishes.
4- After finishing step 3, type in the terminal make.
5- Once step 4 is done, type sudo make install.

Note that you must have cmake already installed in your system and you should be good to go!

Cheers,

Sorry this is an old thread, but I am facing an issue with launching gmsh GUI after successful installation.

For some reason, the Ubuntu Software lists very old version of gmsh (2.10.0) which does not have Boolean features. I need to use boolean operations so I wanted to upgrade to latest 3.0.6 version. apt-get upgrade didn't work. So I decided to do a clean install from source code.

gmsh --version gives me this:

3.0.6

...so I know that it has installed correctly.


However if I type in gmsh in the terminal, it doesn't open the GUI. Instead it gives me an output of

gmsh -help

Why? How do I launch gmsh?

The system has Ubuntu 16.04 LTS and gmsh is being installed in /opt/gmsh

Anyone knows what the issue could be?

[orxan.shibli]

To build gmsh from source with GUI support, FLTK should be installed.

Thanks for your quick reply.

I just installed.

locate libfltk

gives me a list of locations-files.

Will I need to remove and recompile gmsh now?
Update: Okay. I did anyway. Still no GUI. Just the same help options printed in terminal window.

I find this extremely weird:

dpkg --list

shows me older version of gmsh (2.10) which I had removed from Ubuntu Software itself. But it doesn't show me the latest installed version 3.0.6.

rc  gmsh           2.10.1+dfsg1 amd64        Three-dimensional finite element 
ii  gmsh-doc       2.10.1+dfsg1 all          Three-dimensional finite element

I have no idea what's going on here.

I am installing gmsh in /opt/gmsh and source directory is in Downloads so it's not exactly source-directory/build location. But here's the output:

Interesting.. it says it could not find fltk libraries. What now?

[orxan.shibli]

cmake says

Could NOT find FLTK (missing: FLTK_LIBRARIES)

I suppose you followed standard "configure, make and make install" for FLTK. Can you run "sudo ldconfig" and try "cmake .." to see if FLTK libraries are found.

Nope. cmake output is still same..

[orxan.shibli]

Please delete CMakeCache.txt and try again. If it fails again please show output of "whereis fltk-config" and CMakeCache.txt.

Alright! That seems to have worked.

Nonetheless I ran this

whereis fltk-config

and I get the following

fltk-config:

So still weird things exist. Also the warnings about BLAS etc still remain to be resolved.

[orxan.shibli]

What do you mean with "it worked"? Output says

Could NOT find FLTK (missing: FLTK_LIBRARIES)

[deepbandivadekar]

Oh my mistake. I did not notice that line for some reason. I was wondering why this cmake output is longer than the previous..

[orxan.shibli]

At least it is known that problem is due to cmake not finding fltk libraries. Once its found GUI should work. I am curious why you want to build from source but not use binary distribution.

Well simply because am a Windows-to-Linux guy and not very familiar with how things work. The binary zip file from gmsh.info did not have any makefiles in it. Just an application in bin which when clicked didn't do anything. So looked for alternatives..

[orxan.shibli]

I see. You can open terminal and do "./gmsh" in the bin directory.

[deepbandivadekar]

Okay. This opens gmsh but any given geometry looks all messed up. The same files opened perfectly well in previous version 2.10.
I believe that's something to do with the warnings we saw earlier in the cmake log?


Edit: Even the gmsh icon looks distorted..

[orxan.shibli]

I my case both source and binary versions work good. You probably need to separate questions and ask them one by one on stackoverflow. They would give much better answers to you.

[deepbandivadekar]

Okay I'll do that and I'll update once its resolved.

Thank you for sticking around patiently.
