Bug ID: 91396
Summary: Link error when I use -fvtable-verify=std and -static
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: niva at niisi dot msk.ru
Target Milestone: ---
I have built gcc-7.4.0 with --enable-vtable-verify for x86_64 under Fedora 27:
$HOME/src/gcc-7.4.0/configure --srcdir=$HOME/src/gcc-7.4.0 --verbose
--enable-vtable-verify --enable-languages=c,c++,fortran --enable-lto
--prefix=$HOME/local-gcc
When I run:
$ ~/local-gcc/bin/g++ -fvtable-verify=std -O2 -static t.C -o t.exe
the following error occurs:
~/local-gcc/lib/gcc/x86_64-pc-linux-gnu/7.4.0/vtv_end.o: In function
`__VLTprotect':
vtv_end.c:(.text.startup+0x0): multiple definition of `__VLTprotect'
~/local-gcc/lib/gcc/x86_64-pc-linux-gnu/7.4.0/../../../../lib64/libvtv.a(vtv_end.o):~/build/native-gcc/x86_64-pc-linux-gnu/libvtv/vtv_end.c:59:
first defined here
$ cat t.C
int main () {return 0;}
I have fixed the problem by deleting vtv_end.o from
~/local-gcc/lib64/libvtv.a but I'm not sure it's OK.
