Compilation error in example applications

[mm]

Hi,

Trying to compile all tutorial and example applications in the latest
git checkout of hermes, hermes-tutorial, and hermes-examples I
encountered the following compilation error in hermes-examples:

System configuration: Linux Ubuntu 10.04, gcc 4.4.3

Many errors of this type follow if I try to compile other Euler examples
individually. Any help is appreciated.

Hello,

Euler examples are probably ones that are undergoing most development.
Could you please tell me what branches are you using (master or
devel)?

Thank you very much,
Regards,
Lukas

Hi Lukas,

I am working with the master branch both for the examples and the core part of hermes.

Thank you very much for your help,

Matthias

Hello,

I just checked and the compilation works just fine, although I have
gcc 4.6.3, but that should not be an issue. Anyways, could you try?

The errors you sent look like you may have some inconsistency in the
installation.

Do you install to system directories? I.e., in the case of the library
(core), do you just type "sudo make install"?

If you do, there is no settings necessary in the hermes-examples
repository and you can then just type "cmake ." followed by "make",
and it should compile without any problems.

Thank you for trying,

Regards,
Lukas
