gdb无法在Mac Sierra中正确安装

Question

I tried everything I can find about installing gdb, but still could not make it work.

Here is how I install and run gdb:

1. install gdb with brew install gdb

2. then it tells me to do the following

   (experiment3.5) ->brew install gdb Updating Homebrew... ==> Downloading https://homebrew.bintray.com/bottles/gdb- 8.0.1.sierra.bottle.tar Already downloaded: /Users/Natsume/Library/Caches/Homebrew/gdb- 8.0.1.sierra.bottle.tar.gz ==> Pouring gdb-8.0.1.sierra.bottle.tar.gz ==> Caveats gdb requires special privileges to access Mach ports. You will need to codesign the binary. For instructions, see:
   https://sourceware.org/gdb/wiki/BuildingOnDarwin

   On 10.12 (Sierra) or later with SIP, you need to run this:

   echo "set startup-with-shell off" >> ~/.gdbinit

3. I did finish these two steps. I did the codesign task by following exact instruction here

4. everything goes smoothly. however, when I ran the following code, I still get the same error message

I ran gdb python test.py and received following message

(experiment3.5)  ->gdb python signal_test.py

Python Exception <type 'exceptions.ImportError'> No module named libpython:
"/Users/Natsume/Documents/shendusuipian/pytorch/raw_pytorch/60min_intro/signal_test.py" is not a core dump: File format not recognized

5. then I did download libpython.py , but I don't know what to do with it.
6. I don't have such folder /Users/travis/miniconda3/conda-bld/python_1494603145199/work/Python-3.5.3/Programs/python.o' as stated in the warning message above

Update I have tried to follow the steps here , I directly used the gdb8.01.tar.gz downloaded through brew install gdb , but I got error message below.

Focus on one: /Users/Natsume/Desktop/src/gdb/8.0.1
 ->./configure --prefix=$HOME/opt/usr/local

update I ran the code from the link above, and installed, configured gdb8.0, however, I don't have a folder as $HOME/opt/usr/local , but only /opt/usr/local . Therefore, although ./configure --prefix=$HOME/opt/usr/local ran through, but I still can't run codesign -f -s "gdb-cert" <gnat_install_prefix>/bin/gdb , as there is no $HOME/opt/usr/local .

update

exactly forllowing the link above, I can install gdb 8.0 , but I can't run gfortran ,

(experiment3.5)  ->gfortran
-bash: gfortran: command not found

nor can I run gdb python test.py with success:

(experiment3.5)  ->gdb --args python signal_test.py

Answer 1

I have spent quite some time on this one. You need to compile it from sources.

Take a look here:

Running GDB in macOS sierra

It worked for me ;)

Just one note, make sure to code sign it! Notes can be found here: Codesigning the Debugger

Update:

for python stuff, take a look here

http://unconj.ca/blog/setting-up-gdb-for-debugging-python-on-os-x.html

as for gdb itself

it should be enough to test it following way

// simple.c
#include <stdio.h>

int main() {
  printf("Hello\n");
  return 0;
}

and then

# assuming that gdb is signed
cc -g -o simple simple.c
gdb ./simple

Update - System Integrity Protection

When it comes to some areas (eg /usr/bin) you won't have access there due to the fact that System Integrity Protection is on. You need to turn it off:

# You need to boot to Recovery OS in a first place (before you call csrutil)
> csrutil disable

# you can also use another location as output
> lipo /usr/bin/python -thin x86_64 -output ~/python64

Take a look here when it comes to details of System Integrity Protection .
