[oi-dev] LD relocation error and GCC visibility

2014-08-26 Thread Aurélien Larcher 
Hi,
for what it is worth, just a note as I encountered relocation errors while
compiling VTK and Paraview seemingly due to linking shared libraries to
non-PIC static libraries.

- All the objects had been compiled with -fPIC.
- Passing -mimpure-text to GCC to ignore the linker error (removing -z text
from the flags passed to ld) leads to immediate segmentation fault.
- Disabling visibility allowed to build a functioning library.

Text relocation remains referenced
against symboloffsetin file
std::_Rb_treevtkVariant, std::pairvtkVariant const, int,
std::_Select1ststd::pairvtkVariant const, int , std::lessvtkVariant,
std::allocatorstd::pairvtkVariant const, int 
::_M_erase(std::_Rb_tree_nodestd::pairvtkVariant const, int *)

0x428eCMakeFiles/vtkInfovisCore.dir/vtkReduceTable.cxx.o
ld: fatal: relocations remain against allocatable but non-writable sections
collect2: error: ld returned 1 exit status

Is GCC visibility known to be broken with Solaris/Illumos ld ?
Best regards,

Aurelien

Hi.
I don't know if it's broken in some way, but I've seen errors related to 
-fvisibility=hidden while building OpenOffice.  Without producing some 
simple test sample where this works not as expected I'd avoid saying 
that it's broken.

A _really_ simple test case would be appreciated, I'm not exactly sure
what you'd need to do to create one, though.
