Compilation Problem on demo directory.

[jl.gil...@gmail.com]

Dear NT2 team,

I'm working on radio algorithms parallelisation.

I'm trying to use NT2, looking for some DSEL features.

I encounter some problems when compiling the code in "demo" directory.

For instance, "mandelbrot" demo compilaiton gives the following result:

Please find the actual file in attachment.

To be more precise my platform is:

OS:                            Linux centos 6

compiler:                    gcc (GCC) 4.7.2 20121015 (Red Hat 4.7.2-5)
boost lib version:         1.59

I will be grateful if someone could help me.

Thanks in advance.
JLG.

This bug is related to soem changes in Fusion in 1.58/1.59. We had a
workaround for 1.58 but it's not compatible with 1.59.

I'm gonna fix this real quick during the week-end.

Thanks a lot, Joël for your quick response.

To go a little bit further I would like to describe my objective:
 - I would like to build a DSEL in order to generate parallell tasks for different platform among, them there is "OpenMP".
 - Hence, I have some questions:
   - Is it possible to have some information (example/doc) about how to generate code for a target like "OpenMP" ?
   - Is it possible to have some information about how to use Workers/spawners to use them as intermediate elements to generate code for different targets ?

Thanks for your response.
JL Gilbert

OK

Well, currently, compilign with -fopenmp is enoguh to trigger oepNMP support

Can you be more precise on this use case ?

Dear Joel,

I will give you more information about what we would like to do with skeleton...

In the meantime, we have to complete the installation with OpenMP target first.

1. Thanks to tell me in which branch I could update NT2, in order to fix the bug.
2. Thanks to tell me where I could find examples/tests, showing how to use NT2 ?

Regards,
JLG
