Hey All;

Has anyone tried to get the latest DBus release working under OpenWRT ?
I just updated the version numbers in the makefile, and compiled.
The package compiles without errors, but when you attempt to run the dbus-daemon it segfaults.
Even when simply trying to get dbus-daemon --help ...

Looks like it's a linker issue.
If you take the object files from the compile and manually create the shared library,
it loads and dbus-daemon functions.

time to dive into libtool ..

Anyone see anything wrong with this ?
( Output section is from a make V=99 )

It's the linker that is screwing up somewhere cause I can take those object files an manually generate a functional shared library.

Turns out it's the

-Wl,-version-script -Wl,.libs/libdbus-1.ver

options that are screwing it up ..

Anyone with any ideas why ... this

/bin/sh ../libtool --tag=CC   --mode=link armeb-linux-uclibc-gcc  -ffunction-sections -fdata-sections -Os -pipe -march=armv5te -mtune=xscale -funit-at-a-time \
        -fhonour-copts -msoft-float  -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align      \
        -Wsign-compare -Wdeclaration-after-statement -fno-common  -L/home/TMP/OpenWRT/openwrt-svn/trunk-ixp4xx/staging_dir/toolchain-armeb_gcc4.1.2/lib \
        -L/home/TMP/OpenWRT/openwrt-svn/trunk-ixp4xx/staging_dir/armeb/usr/lib -L/home/TMP/OpenWRT/openwrt-svn/trunk-ixp4xx/staging_dir/armeb/lib      \
         -o dbus-uuidgen dbus-uuidgen.o ../dbus/libdbus-1.la

Does not produce a working binary but

armeb-linux-uclibc-gcc  -ffunction-sections -fdata-sections -Os -pipe -march=armv5te -mtune=xscale -funit-at-a-time \
        -fhonour-copts -msoft-float  -Wall -Wchar-subscripts -Wmissing-declarations -Wmissing-prototypes -Wnested-externs -Wpointer-arith -Wcast-align      \
        -Wsign-compare -Wdeclaration-after-statement -fno-common  -L/home/TMP/OpenWRT/openwrt-svn/trunk-ixp4xx/staging_dir/toolchain-armeb_gcc4.1.2/lib \

         -o dbus-uuidgen dbus-uuidgen.o  -ldbus-1

does ?

Lets do some thread-digging...

Still, as of today, I get a segmentation fault (dbus version 1.3.0).

Do the older versions work? I'm trying to port software which depends on v1.3.0, but if an older version works, I might try it the other way around, modifying the software.

The discussion might have continued from here.
