Re: Development of the relax-disp branch. -- May 09, 2013 - 22:26

Hi,

From the messages, I would guess that there was a failure in a previous attempt to compile.  Could you include those error messages as well?  You can get these again by running:

$ scons clean_all

$ scons

Cheers,

Edward

Searching for the problem, seems that "many" run into the same problem.

But I don't know how to fix it?

Do you?

Hi,

This "'cl' is not recognized as an internal or external command" error
is quite common.  For example one solution for older SCons and MSVC is
given at http://www.nmr-relax.com/windows_devel.html#MSVS_scons_issues.
 If you have 64-bit windows, then you have probably been bitten by an
SCons bug that I reported a long time ago and that the SCons
developers stubbornly refuse to fix:

http://scons.tigris.org/issues/show_bug.cgi?id=2849

It is a one line fix which you can see in the second comment.  Just
change those lines in your installed SCons code and it should run.  If
these two suggestions do not work, then we need to look for another
solution.

Regards,

Edward
