Bug ID: 44225
Summary: LLDB build error in llvmorg-9.0.1-rc1 with Python 2
Product: lldb
Version: 9.0
Hardware: PC
OS: Linux
Status: NEW
Severity: release blocker
Priority: P
Component: All Bugs
Assignee: lldb-dev@lists.llvm.org
Reporter: chrs...@google.com
CC: jdevliegh...@apple.com, llvm-b...@lists.llvm.org
LLDB fails to build against Python 2.X, I get the following error message:
/path/to/llvm-build/src/lldb/source/Plugins/ScriptInterpreter/Python/PythonReadline.cpp:52:25:
error: use of undeclared identifier 'PyMem_RawMalloc'; did you mean
'PyMem_Malloc'?
char *ret = (char *)PyMem_RawMalloc(1);
^~~
PyMem_Malloc
/path/to/llvm-build/workstation-sysroot/usr/include/python2.7/pymem.h:52:20:
note: 'PyMem_Malloc' declared here
PyAPI_FUNC(void *) PyMem_Malloc(size_t);
^
/path/to/llvm-build/src/lldb/source/Plugins/ScriptInterpreter/Python/PythonReadline.cpp:60:23:
error: use of undeclared identifier 'PyMem_RawMalloc'; did you mean
'PyMem_Malloc'?
char *ret = (char *)PyMem_RawMalloc(n + 2);
^~~
PyMem_Malloc

1 warning and 2 errors generated.
According to the Python documentation, PyMem_RawMalloc() was only introduced in
3.4: https://docs.python.org/3/c-api/memory.html
Looking at the cherry-picks between llvmorg-9.0.0-rc5 and llvmorg-9.0.1-rc1, I
suspect that this is caused by https://reviews.llvm.org/D69793.
