---|
10 | # GDB uses python internally so we need to link to a suitable python |
---|
11 | # dev kit. The dev kit for python is the header and a library. These |
---|
12 | # files are versioned where the header file is located in a directory |
---|
13 | # based on: |
---|
14 | # |
---|
15 | # pythonM.m/Python.h |
---|
16 | # |
---|
17 | # where 'M' is the major version number and 'm' is the minor verison |
---|
18 | # number. The library is: |
---|
19 | # |
---|
20 | # libpythonM.m.a |
---|
21 | # |
---|
22 | # The python command is 'pythonM' which means we need to query it for |
---|
23 | # the minor number. |
---|
24 | # |
---|
25 | # The python running the RSB may not be suitable, for example a MSC, |
---|
26 | # MSYS or Cygwin version on Windows when we want the MinGW python dev |
---|
27 | # file. A specific version cannot be forced because older versions of |
---|
28 | # GDB can only link to 'python2'. |
---|
29 | # |
---|
30 | # Host support can perform a complex query of the system, for example |
---|
31 | # Windows and set '%{gdb_python2}' and '%{gdb_python3}' with the full |
---|
32 | # path to that version's executable. |
---|
33 | # |
---|
34 | # A configuration of GDB can set the version required by setting |
---|
35 | # '%{gdb-python-version}' to the versions command, eg python2. |
---|
36 | # |
---|
37 | # The procedure is: |
---|
38 | # |
---|
39 | # 1. If the macros '%{gdb_python2}' or '%{gdb_python3}' are present |
---|
40 | # use that path they contain. Assume the path is valid. |
---|
41 | # |
---|
42 | # 2. Does the version of gdb specify a version of python that must be |
---|
43 | # used. Override with '%define gdb-python-version python2'. |
---|
44 | # |
---|
45 | # 3. Search for 'python2' and if not found search for 'python3'. |
