Re: [Gems-users] libelf.so.0 and libpython2.4.so problem

[Daniel Sánchez Pedreño <sanatox@xxxxxxxxx>]

OK, I have already solved my problem.

If you do "export LANG=en" (if you are sugin another language) you can see an error related to "relocation R_X86_64_32 can not be used when making a shared object".

The solution I found is to add the -fPIC command to CC=g++ in common/Makefile.common. You must be sure to perform a "make clean" and to remove manually the "ruby.o" object before a new attempt.

I hope this can be useful to anybody.

Hi Polina,

actually these libraries are included within the simics 3 installation. So, I just pointed LD_LIBRARY_PATH to $HOME/virtutech/simics-3.0.31/amd64-linux/sys/lib/ (where I installed simics).

The previous error has been solved. But know the compilation breaks without any othe information, as you can see here:

=== Building module "ruby" ===
make[2]: se ingresa al directorio `$HOME/gems-2.1/simics_3_workspace/amd64-linux/obj/modules/ruby'

Using the Simics 3.0 API for ruby module

CCLD    ruby.so
make[2]: *** [$HOME/gems-2.1/simics_3_workspace/amd64-linux/lib/ruby.so] Error 2
make[2]: *** Se borra el archivo `$HOME/gems-2.1/simics_3_workspace/amd64-linux/lib/ruby.so'
make[2]: se sale del directorio `$HOME/gems-2.1/simics_3_workspace/amd64-linux/obj/modules/ruby'
make[1]: *** [ruby] Error 2
make[1]: se sale del directorio `/home/sanatox/gems-2.1/simics_3_workspace'
make: *** [all] Error 2

Any idea on how to know what is going on?

PS. Sorry for the comments in spanish :(

I think you're best off checking the Simics requirements in terms of libraries. Do you have the libraries it's looking for?

Dear list,

I am trying to install gems-2.1 with simics-3.0 in a machine which is now properly working with gems-2.1 and simics-2.1.

The compilation of ruby is OK but the problem arises when creating the module. The error message I get is:

=== Building module "ruby" ===

Any help will be apreciated!!!
