Summary: Visibility attributes not supported on Solaris i386
platform
Product: gcc
Version: 4.5.2
Status: UNCONFIRMED
Severity: major
Priority: P3
Component: c++
AssignedTo: [email protected]
ReportedBy: [email protected]
I am porting project to Solaris.
Same code that builds fine on Linux/BSD produces warnings on Solaris 10:
warning: visibility attribute not supported in this configuration; ignored
Compilation of modules succeeds with these warnings.
But later linking of those object modules into the shared library fails with
this message:
ld: fatal: relocation error: R_386_GOTOFF: file
/path/to/library/libmine.a(module.o): symbol <some symbol is here>: relocation
must bind locally.
collect2: ld returned 1 exit status
I have built gcc-4.5.2 myself with the same options on both Linux and Solaris.
Why wouldn't visibility attributes not be supported in Solaris configuration?
Also reading some threads from the past I see that these two messages are
somewhat related. Due to the lack of visibility attributes some symbol with
R_386_GOTOFF becomes global and can't be linked into the shared library as
global.
How to solve such problem when c++ code defines some symbols with "hidden"
attributes and Solaris version of gcc fails to support this?
