Good analysis. I also think it's gcc problem.
BTW, I compiled dcgui on my latest sid i386 machine. From my built
dcgui works fine. I found:
wurlitzer:~/bugs/179781/dcgui-0.70> objdump -x debian/dcgui/usr/bin/dcgui |
grep __fixunsdfdi
wurlitzer:~/bugs/179781/dcgui-0.70> objdump -x src/dc_gui2 | grep __fixunsdfdi
08095ce0 l F .text 000000b2 .hidden __fixunsdfdi
dc_gui2 has hidden attribute __fixunsdfdi, and dcgui binary has no
such entry. dcgui is stripped from dc_gui2. I guess it's toolchain
problem, not glibc. My build of dcgui works fine with:
LD_PRELOAD=/lib/libgcc_s.so.1 dcgui
Moreover, we can see this problem with glib2.0:
wurlitzer:/usr/lib> objdump -x libgobject-2.0.a | grep __fixunsdfdi
00000000 *UND* 00000000 __fixunsdfdi
000007a4 R_386_PC32 __fixunsdfdi
TAGOH Akira (glib2.0 maintainer) said this problem is also existed in
RedHat beta gnome.
This problem is caused by gvaluetransform.o:
wurlitzer:~/bugs/179781/glib2.0-2.2.1/build-tree/glib-2.2.1/gobject> objdump
-x gvaluetransform.lo | grep __fixunsdfdi
00000000 *UND* 00000000 __fixunsdfdi
000007e1 R_386_PLT32 __fixunsdfdi
wurlitzer:~/bugs/179781/glib2.0-2.2.1/build-tree/glib-2.2.1/gobject> objdump
-x gvaluetransform.o | grep __fixunsdfdi
00000000 *UND* 00000000 __fixunsdfdi
000007a4 R_386_PC32 __fixunsdfdi
And gvaluetransform.o is compiled:
/bin/sh ../libtool --mode=compile gcc -DHAVE_CONFIG_H -I. -I. -I..
-DG_LOG_DOMAIN=\"GLib-GObject\" -I.. -I../glib -I.. -DG_DISABLE_CAST_CHECKS
-DG_DISABLE_DEPRECATED -DGOBJECT_COMPILATION -DG_DISABLE_CONST_RETURNS -pthread -g
-O2 -Wall -c gvaluetransform.c
rm -f .libs/gvaluetransform.lo
gcc -DHAVE_CONFIG_H -I. -I. -I.. -DG_LOG_DOMAIN=\"GLib-GObject\" -I..
-I../glib -I.. -DG_DISABLE_CAST_CHECKS -DG_DISABLE_DEPRECATED -DGOBJECT_COMPILATION
-DG_DISABLE_CONST_RETURNS -pthread -g -O2 -Wall -c gvaluetransform.c -fPIC -DPIC -o
.libs/gvaluetransform.lo
gcc -DHAVE_CONFIG_H -I. -I. -I.. -DG_LOG_DOMAIN=\"GLib-GObject\" -I..
-I../glib -I.. -DG_DISABLE_CAST_CHECKS -DG_DISABLE_DEPRECATED -DGOBJECT_COMPILATION
-DG_DISABLE_CONST_RETURNS -pthread -g -O2 -Wall -c gvaluetransform.c -o
gvaluetransform.o >/dev/null 2>&1
mv -f .libs/gvaluetransform.lo gvaluetransform.lo
Hmm, so I change gvaluetransform.c as:
wurlitzer:~/bugs/179781/glib2.0-2.2.1/build-tree/glib-2.2.1/gobject> diff -e
gvaluetransform.c.org gvaluetransform.c
137,441d
133c
//DEFINE_CAST (double_uint64, v_double, guint64, v_uint64);
.
wurlitzer:~/bugs/179781/glib2.0-2.2.1/build-tree/glib-2.2.1/gobject> objdump
-x gvaluetransform.o | grep __fixunsdfdi
wurlitzer:~/bugs/179781/glib2.0-2.2.1/build-tree/glib-2.2.1/gobject>
This __fixunsdfdi is vanished! I also changed it as:
DEFINE_CAST (double_uint64, v_double, gint64, v_uint64);
^^^^^^
This also fixes the problem.
The conclusion is:
- dcgui should be rebuilt with the latest sid environment.
- gobject in glib2.2 still has problem, it's related with this define_cast.
At least it's not glibc problem, but gcc problem. I will reassign this bug
to gcc, but I would like to know the result of more investigation.
Guido, Tagoh, can you find what is the problem?
