The problem is due to shared libraries. Need to set up so looks for shared
libraries in when running the tests. Below demonstrates the problem.
$
LD_LIBRARY_PATH=/home/wcohen/systemtap_write/obj/lib-elfutils:/home/wcohen/systemtap_write/obj/lib-elfutils/systemtap:$LD_LIBRARY_PATH
./stap ../src/testsuite/systemtap.samples/tcptest.stp
Okay the following works:
$ LD_LIBRARY_PATH=/home/wcohen/systemtap_write/intall2/lib/systemtap ./stap
../src/testsuite/systemtap.samples/tcptest.stp
This does not work:
$ ./stap ../src/testsuite/systemtap.samples/tcptest.stp semantic error: failed
to retrieve return value location: identifier '$return' at
/home/wcohen/systemtap_write/intall2/share/systemtap/tapset/tcp.stp:129:9

Pass 2: analysis failed. Try again with more '-v' (verbose) options.
