Comment(by drkirkby):
I know more about this problem than was on the ticket. The shared
libraries generated by R have non-PIC code in them. This is easy to prove,
as detailed here
http://blogs.sun.com/rie/entry/my_relocations_don_t_fit
basically running
{{{
$ elfdump -d library | grep TEXTREL
}}}
should produce no output, but it does in the case of the three R libraries
{{{
drkirkby@hawk:~/sage-4.6.2.rc1/local/lib/R/lib$ elfdump -d libR.so | fgrep
TEXTREL
[25] TEXTREL 0
[34] FLAGS 0x4 [ TEXTREL ]
drkirkby@hawk:~/sage-4.6.2.rc1/local/lib/R/lib$ elfdump -d libRblas.so |
fgrep TEXTREL
[19] TEXTREL 0
[28] FLAGS 0x4 [ TEXTREL ]
drkirkby@hawk:~/sage-4.6.2.rc1/local/lib/R/lib$ elfdump -d libRlapack.so |
fgrep TEXTREL
[18] TEXTREL 0
[27] FLAGS 0x4 [ TEXTREL ]
drkirkby@hawk:~/sage-4.6.2.rc1/local/lib/R/lib$
}}}
That blog page also describes how to track down the bad code, but its far
from obvious to me what to do. I am totally lost.
The problem is also seen on 32-bit code on both SPARC and x86, but it only
causing linking issues on 64-bit code. So essentially one could debug this
problem on t2.math with either a 32-bit or 64-bit build. But I can't
follow the logic needed to do this debugging.
