[gentoo-science] tachyon-0.98.9-r1 fails to install due to wrong USE flags

[rose]

Hi,
I try to install [sage-on-gentoo] sage. I come until tachyon.
'emerge tachyon' fails with:

>>> Emerging (3 of 20) media-gfx/tachyon-0.98.9-r1
  * tachyon-0.98.9.tar.gz RMD160 SHA1 SHA256 size ;-) ...               
                                                                        
                                            [ ok ]
  * ERROR: media-gfx/tachyon-0.98.9-r1 failed (setup phase):
  *   tachyon does not support MPI with OpenGL and threads

openmpi was installed with "cxx fortran ipv6 romio threads" USE flags.  
There is no OpenGL USE flag for openmpi:

root@caiman:/root(16)# emerge -pvD openmpi

These are the packages that would be merged, in order:

Calculating dependencies... done!
[ebuild   R    ] sys-cluster/openmpi-1.5.3-r2  USE="cxx fortran ipv6  
romio threads -heterogeneous -infiniband -mpi-threads -pbs -sctp  
-slurm -vt" 0 kB

What should, I do only to remove the threads USE flag from openmpi?  
What could be the consequences if I remove the threads USE flag, e.g.  
for Rmpi?

Regards

I have now removed the threads USE flag from openmpi, but 'emerge  
tachyon' still fails with the same error:

root@caiman:/root(26)# emerge -vuND sage

These are the packages that would be merged, in order:

Hi,

you have to find a combination of USE flags which work together. In your case, I 
suggest removing the mpi flag and keeping the opengl and threads flags. This 
will enable accelerated rendering with OpenGL and threads - which will not 
work with the Message Passing Interface (MPI).

When I wrote the tachyon ebuild it was not easily possible to define a valid 
combination of USE-flags and I have to admit the current solution is not the 
best. I think with EAPI=4 it should be possible to find a better approach.

Cheers,
Christopher

Hi Christopher,

I understand, that I should remove the mpi USE flag from tachyon. I did this.
Then I suppose that the global thread flag does not mean any problem,  
So I deleted again the removal of the thread USE flag from openmpi.  
With this settings I was able to emerge tachyon-0.98.9-r1.
