I suspect I know the problem. The tool I'm building links with a bunch of other
libraries we've developed, which I didn't write. I only modified the makefile
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 real BSD8 system and
there are clear differences:
BSD7 binary:
libm.so.5 => /lib/libm.so.5 (0x800724000)
libreadline.so.7 => /usr/local/lib/compat/libreadline.so.7 (0x800843000)
libncurses.so.7 => /usr/local/lib/compat/libncurses.so.7 (0x800980000)
libcrypto.so.5 => /usr/local/lib/compat/libcrypto.so.5 (0x800acc000)
libdevinfo.so.4 => /usr/local/lib/compat/libdevinfo.so.4 (0x800d5e000)
libkvm.so.4 => /usr/local/lib/compat/libkvm.so.4 (0x800e60000)
libutil.so.7 => /usr/local/lib/compat/libutil.so.7 (0x800f68000)
libthr.so.3 => /lib/libthr.so.3 (0x801077000)
libc.so.7 => /lib/libc.so.7 (0x80118f000)
BSD8 binary:
libm.so.5 => /lib/libm.so.5 (0x800724000)
* libreadline.so.8 => /lib/libreadline.so.8 (0x800843000)
* libncurses.so.8 => /lib/libncurses.so.8 (0x800981000)
* libcrypto.so.6 => /lib/libcrypto.so.6 (0x800acd000)
* libdevinfo.so.5 => /usr/lib/libdevinfo.so.5 (0x800d67000)
* libkvm.so.5 => /lib/libkvm.so.5 (0x800e69000)
* libutil.so.8 => /lib/libutil.so.8 (0x800f71000)
libthr.so.3 => /lib/libthr.so.3 (0x801081000)
libc.so.7 => /lib/libc.so.7 (0x801199000)
I suspect the libkvm library is the culprit. This list though is what I need to
aim for using the sysroot approach.
