Evening All,
So I need a call graph pass and having done several other passes, I went to work
on a simple pass, inheriting from CallGraphSCCPass.
However, while I was quickly able to build the pass, when I went to run it I got
the following:
opt -load ../Passes/HierchalFunctions/Hierchal/hierchal.dylib -hierchal <
hello.bc > /dev/null
Error opening '../Passes/HierchalFunctions/Hierchal/hierchal.dylib':
dlopen(../Passes/HierchalFunctions/Hierchal/hierchal.dylib, 9): Symbol not
found: __ZTIN4llvm16CallGraphSCCPassE
Referenced from:
/Users/jcarlson/Software/LLDB/Passes/HierchalFunctions/Hierchal/hierchal.dylib
Expected in: flat namespace
in
/Users/jcarlson/Software/LLDB/Passes/HierchalFunctions/Hierchal/hierchal.dylib
-load request ignored.
opt: Unknown command line argument '-hierchal'. Try: 'opt
-help'
opt: Did you mean '-verify'?
It was suggested that I might have forgotten to link in the ipa lib so I tried
to modify my cmakelists and then even ran by hand:
/usr/local/bin/clang++ -dynamiclib -Wl,-headerpad_max_install_names
-Wl,-flat_namespace -Wl,-undefined -Wl,suppress -o hierchal.dylib
-install_name
/Users/jcarlson/Software/LLDB/Passes/HierchalFunctions/Hierchal/hierchal.dylib
CMakeFiles/hierchal.dir/Hierchal.o -L/usr/local/lib -lLLVMipa -lLLVMAnalysis
-lLLVMTarget -lLLVMCore -lLLVMMC -lLLVMObject -lLLVMSupport -lpthread
When I run otool -l on the dylib I get:
otool -L hierchal.dylib
hierchal.dylib:
/Users/jcarlson/Software/LLDB/Passes/HierchalFunctions/Hierchal/hierchal.dylib
(compatibility version 0.0.0, current version 0.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version
159.1.0)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current version
52.0.0)
I have the feeling I'm just missing something simple but I've been
banging my head on this for a bit now… Any suggestions?
Thanks,
- Jared
