+Petar Hi Mohit,
I wanted to make sure you are aware of some work we're doing on Linux. We're adding support for remote Linux (and Android) targets via PlatformRemoteGDBServer and lldb-gdbserver. We would also like to replace local Linux debugging support with a connection to a local lldb-gdbserver instance. This way there will only be one code path for Linux local or remote debugging. We intend to make the remote support for Linux/Android very good so we expect this will be a significant step forward for local Linux debugging. Some of our work isn't ready to upstream yet so we're working out of a separate branch. Here are instructions for building and running our tree. The most important bit is "export PLATFORM_LINUX_FORCE_LLGS_LOCAL=1" which enables the code paths for local debugging via a local lldb-gdbserver instance. #!/bin/bash ROOT_DIR=$HOME/ll/googd mkdir -p $ROOT_DIR cd $ROOT_DIR git clone http://github.com/tfiala/lldb.git (cd lldb && git checkout dev-thread-state-coordinator) git clone http://llvm.org/git/llvm.git (cd llvm && git checkout 7d7b761cd0f4f4d17a79324668b1ec758b7791ad) git clone http://llvm.org/git/clang.git (cd clang && git checkout 7894c14c006941684f6c8964ed71c9b14c3f0edb) git clone http://github.com/tfiala/lldb-tools cd llvm/tools ln -s ../../clang clang ln -s ../../lldb lldb cd $ROOT_DIR lldb-tools/scripts/lldb_configure.py -c -n -l -g -s -a --ccache -b build cd build # use lldb-gdbserver when debugging local processes export PLATFORM_LINUX_FORCE_LLGS_LOCAL=1 ninja && ninja check-lldb Vince On Jan 8, 2015 1:49 AM, "Mohit K.
