MG5 does not work with gcc v6.2.0?

Hi,

Indeed it seems that ninja is not compatible with your version of gcc.
I will report this to Ninja author such that they are aware of that problem.
This program is optional and using it only improve the speed of the code.
So this is not a True problem to not have it install.

Concerning the stdhep problem. This one seems more serious.
Could you attach the file starting with
> log.mcfio.
which should be (I guess) in
> /home/goutam/MADGRAPH/MG5_aMC_v2_5_1/vendor/StdHEP/mcfio/src

Cheers,

Olivier

Hi Olivier,
                   I only found log file in /MG5_aMC_v2_5_1/vendor/StdHEP/ directory.

I am pasting a part of it here:

make[1]: Entering directory `/home/goutam/MADGRAPH/MG5_aMC_v2_5_1/vendor/StdHEP/mcfio/src'
Creating shared library ../../lib/libFmcfio.so ...

make[1]: *** [../../lib/libFmcfio.so] Error 1
make[1]: Leaving directory `/home/goutam/MADGRAPH/MG5_aMC_v2_5_1/vendor/StdHEP/mcfio/src'

I don't know how to attach file here. If you want I can send you the full log file in your Durham account?

Best Regards,
Goutam

Hi,

Looks like that your gcc is not able to link against a library of your system/gcc:
crtbeginS.o

Google does not seems to help that much on that one (probably because that version of gcc is quite new)
Maybe you should report this to the gcc bug tracker. This is probably not a gcc bug but they should be able to tell you
which linux library you need to install on your system.

Cheers,

Olivier

Hi,
    do you know whether it will work with gcc-v5 series like GCC 5.4(which is a rolling version)?
I know it works with GCC4.8 but its obsolete.

Thanks,
Goutam

Hi,

yes gcc5 works in general. But since your problem is the fact that a standard library is missing, I’m worry that you can face the same problem
in gcc5.

Cheers,

Olivier
