[Gems-users] Can not compile Ruby and Opal on amd64 and no useful error message is available

[Sitos Lin <sitos.lin@xxxxxxxxx>]

Hello all:

  I try to migration my SIMICs/Gems/DRAMsim package from x86-linux to amd64-linux. I have fixed several errors. However, I still can not compile Opal and Ruby. I use g++-4.2.4 on amd64 system. The message for Opal is as following.

=== Building module "opal" ===

  The message for Ruby is as following.

  I think the problem of Opal and that of Ruby are different. The message of opal indicates that there is no main, but the message of ruby has no useful information. Does anyone encounter the same problems on amd64 machines? Thanks a lot.
