[SyncEvolution] building activesyncd: undefined reference to `eas_account_set_server_protocols'

Hello! I'm running into a baffling link error when rebuilding activesyncd f72a6ce from today: make[1]: Entering directory `/home/pohly/work/activesyncd/eas-daemon/src' /bin/bash ../../libtool --tag=CC

`eas_account_set_server_protocols' collect2: ld returned 1 exit status Why doesn't the linker consider libeasaccount.so.0 when checking for this symbol? Why does it care in the first place? [a bit later] Found it. stracing the final ld invocation shows that it looks at an old libeasaccount.so.0 in my /tmp/activesyncd install dir. Wiping that out first avoided the issue. I still don't know why ld considers those old libs at all. Does setting the rpath have that effect? That is the only reference to /tmp/activesyncd/lib.
