I suspect I know the problem. The tool I'm building links with a bunch of o=
ther libraries we've developed, which I didn't write. I only modified the m=
akefile of my own code. I'm going to have to tweak the makefiles of a dozen=
different library modules. That'll be more work but it needs to be done to=
confirm this approach works. I checked the binaries built on BSD7 and a re=
al BSD8 system and there are clear differences:
BSD7 binary:
libm.so.5 =3D> /lib/libm.so.5 (0x800724000)
libreadline.so.7 =3D> /usr/local/lib/compat/libreadline.so.7 (0x800=
843000)
libncurses.so.7 =3D> /usr/local/lib/compat/libncurses.so.7 (0x80098=
0000)
libcrypto.so.5 =3D> /usr/local/lib/compat/libcrypto.so.5 (0x800acc0=
00)
libdevinfo.so.4 =3D> /usr/local/lib/compat/libdevinfo.so.4 (0x800d5=
e000)
libkvm.so.4 =3D> /usr/local/lib/compat/libkvm.so.4 (0x800e60000)
libutil.so.7 =3D> /usr/local/lib/compat/libutil.so.7 (0x800f68000)
libthr.so.3 =3D> /lib/libthr.so.3 (0x801077000)
libc.so.7 =3D> /lib/libc.so.7 (0x80118f000)
BSD8 binary:
libm.so.5 =3D> /lib/libm.so.5 (0x800724000)
* libreadline.so.8 =3D> /lib/libreadline.so.8 (0x800843000)
* libncurses.so.8 =3D> /lib/libncurses.so.8 (0x800981000)
* libcrypto.so.6 =3D> /lib/libcrypto.so.6 (0x800acd000)
* libdevinfo.so.5 =3D> /usr/lib/libdevinfo.so.5 (0x800d67000)
* libkvm.so.5 =3D> /lib/libkvm.so.5 (0x800e69000)
* libutil.so.8 =3D> /lib/libutil.so.8 (0x800f71000)
libthr.so.3 =3D> /lib/libthr.so.3 (0x801081000)
libc.so.7 =3D> /lib/libc.so.7 (0x801199000)
I suspect the libkvm library is the culprit. This list though is what I nee=
d to aim for using the sysroot approach.=20
