hi there, i'm running freebsd-2.1-release. the assembler shipped with
the distribution ist gas v1.92.3.
when compiling the gnu c++ library v2.7.2 (using gcc v2.7.2 compiled
previously) i encountered the warning shown in the subject. it happened
during compilation of the file libg++-2.7.2/libstdc++/exceptioni.cc.
i was trying to build a shared version of the library (the static one was
ok). the command line was
gcc <options> -O3 <more options> -fpic -O0 -fhandle-exceptions -frtti
<options>.
the message of the assembler was
"assembler warning: GOT relocation burb: symbol "___EXCEPTION_TABLE__"
should be global".
without "-O0 -fhandle-exceptions -frtti" everything is ok. the objectfile
produced lead the linkeditor into a core-dump. the command issued was ld
-x -r exceptioni.o.
can anyone explain this behaviour? are there solutions available (newer
version of gas, ...)? why do i have to remove local symbols by invoking
ld -x -r before building the shared library?
thank you all in advance.
