I didn't get much time to work on it after that. Today, I had a look at it.
I included a workaround for that weird marco incompatibility error between
LLVM and wxWidgets. I just commented out the line - "#define _(s)
wxGetTranslation(wxT(s))" in wx/intl.h and it built successfully.
I fixed issues with lib/Snapshot/WriteSnapshot.cpp. Now opt-snap tool can
capture snapshots.
If I run llvm-tv.exe without any snapshots in the
/tmp/llvm-tv-*username*/snapshots
folder, at least the LLVM Visualizer window pops up. But, with the
snapshots in the folder, it gives segmentation fault after showing
"Processing: /tmp/llvm-tv-*username*/snapshots/*.bc" for each snapshot
bitcode file.
If someone is interested in helping to fix the snapshot processing part by
llvm-tv, I can share the code. Please let me know.
