[lldb-dev] LLDB problem about building with Python
Hi LLDB devs, I'm working on porting LLDB to my own architecture. I choose to use the target-definition-file(python) to let LLDB support my architecture based on my situation(already have a workable GDB-stub and the target is an embedded DSP). The usage: (lldb) settings set plugin.process.gdb-remote.target-definition-file /path/to/_target_definition.py (lldb) gdb-remote So I think I definitely need to rebuild LLDB with python support(cmake with -DLLDB_ENABLE_PYTHON=1 according to https://lldb.llvm.org/resources/build.html). But problem comes: getting this error: CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: /export/pfs/home/lte_dsp/hongrui/DEBUG/jihai_lldb/jihai_lldb/lldb/scripts/Python/modules/readline/libedit_INCLUDE_DIRS used as include directory in directory /export/pfs/home/lte_dsp/hongrui/DEBUG/jihai_lldb/jihai_lldb/lldb/scripts/Python/modules/readline libedit_LIBRARIES (ADVANCED) linked by target "readline" in directory /export/pfs/home/lte_dsp/hongrui/DEBUG/jihai_lldb/jihai_lldb/lldb/scripts/Python/modules/readline This problem persists even after I add -DLLDB_ENABLE_LIBEDIT=0 My cmake version is 3.5.2, the LLDB/LLVM version I choose to work with is 7.0.1 My complete command is: cmake -G "Unix Makefiles" -DLLDB_ENABLE_LIBEDIT=0 -DLLDB_ENABLE_PYTHON=1 -DPYTHON_INCLUDE_DIR=/usr/include/python2.7 -DPYTHON_LIBRARY=/usr/lib64/libpython2.7.so.1.0 -DLLVM_TARGETS_TO_BUILD=JiHai -DLLVM_ENABLE_PROJECTS='lldb' -DLLDB_EXPORT_ALL_SYMBOLS=1 -DCMAKE_BUILD _TYPE=Debug -DCMAKE_INSTALL_PREFIX=. ../llvm make -j 8 Why the error persists even with -DLLDB_ENABLE_LIBEDIT=0? Does this mean that LLDB python support also need libedit? And what should I do to make LLDB_build_with_python correct(I just want to use the target-definition-file)? Kind regards, Rui___ lldb-dev mailing list lldb-dev@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev

Back in 7.0, this was called LLDB_DISABLE_LIBEDIT (with the inverted meaning of values). pl ___ lldb-dev mailing list lldb-dev@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/lldb-dev
