When running xorg-server, I'm
getting Unsupported relocation type 6 in non-PLT relocations.
I have checked with objdump -R, and it seems to me
xc/programs/Xserver/fb/fbcompose.c
is the one causing this problem. The way I have reached this code was:
- looking the address of problems
ttyp6:makoto@mini 16:54:36/070408(...x11/xorg-server)> \
objdump -R work.mini/xc/programs/Xserver/fb/libfb.so | grep ADDR16

- looking the code by disassembling:
objdump -d work.mini/xc/programs/Xserver/fb/libfb.so
00031540 <__fixdfdi>:

31558: 41 9c 00 18 blt- cr7,31570 <__fixdfdi+0x30>
<__fixdfdi> ..
__fixdfdi is defined in
lib/libc/quad/fixdfdi.c.
The problem is not in this function but how to reach this address ?
No, this function is compiled in libfb.so.
nm work.mini/xc/programs/Xserver/fb/libfb.so |grep fixdf
00031540 T __fixdfdi
The Mechanism to include 'T __fixdfdi' is this:
- compile fbcompose.c getting fbcompose.o
- this function include the reference to 'U __fixdfdi'
ttyp3:makoto@bologna 7:58:50/070409(...Xserver/fb)> nm fbcompose.o |grep fixdf
U __fixdfdi
- following cc resolves the above undefined reference.
cc -o libfb.so -shared -Wl,-rpath,/usr/pkg/xorg/lib -nostdlib
fbmodule.o fbarc.o fballpriv.o fbbits.o fbblt.o fbbltone.o
fbbstore.o fbcmap.o fbcompose.o fbcopy.o fbedge.o fbfill.o
fbfillrect.o fbfillsp.o fbgc.o fbgetsp.o fbglyph.o fbimage.o
fbline.o fboverlay.o fbpixmap.o fbpoint.o fbpush.o fbscreen.o
fbseg.o fbsetsp.o fbsolid.o fbstipple.o fbtile.o fbtrap.o
fbutil.o fbwindow.o fb24_32.o fbpict.o fbmmx.o fbpseudocolor.o
-Wl,-Bstatic
-lgcc -Wl,-Bdynamic
removing '-lgcc -Wl,-Bdynamic' from Makefile
resolves this problem.
