lhapdf with undeclared identifier 'boost'

Hi,

lhapdf6.2 is not yet supported in MG5aMC, It is planned for the next version of the code (2.6.1).

Cheers,

Olivier

Dear Olivier,
Thanks for your answer.
So, I want to know how can I install lower version lhapdf, such as lhapdf6.1.x on my Mac through Homebrew? I don't want to install lhapdf6 by the syntax" MG5>install lhapdf6". Because there is something wrong about its interface on my Mac.
Thanks for helping!

Best Regards,
Ruibo Li

Thanks Olivier Mattelaer, that solved my question.

Dear Olibier,
Ok, thanks for your suggestions!
 I will try to install lhapdf6 via the direct compilation of the source again.

Best Regards,
Ruibo Li
