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/xxxx_target_definition.py
(lldb) gdb-remote xxxx
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
