Details:
Hello, all.
I am trying to build libobjc2 1.6 (from svn) using a recent build of clang
(NSNumber, NSArray, NSDictionary and BOOL literals!!) on Ubuntu 11.10. It
seems to compile fine, but when it gets to linking, this happens:
/usr/bin/ld: libobjc.o: relocation R_X86_64_32 against `.data' can not
be used when making a shared object; recompile with -fPIC
libobjc.o: could not read symbols: Bad value
-fPIC is already specified among the CFLAGS on line 9 of the makefile.
This is a mostly-clean, fresh install of Ubuntu 11.10 in VMware Fusion 4.
Mostly-clean because of the aforementioned Clang 3.1 installation, as well as
compiler-rt (for libblocksruntime, also from trunk) and libdispatch (and its
dependencies, libpthread_workqueue and libkqueue). There is no Objective-C
runtime installed.
This is the build output in its entirety:
