从github获取源代码
TensorFlow是一个灵活的端到端的机器学习框架。这儿使用1.15版本，编译完后大概6GB，Debug的时候GDB加载到内存大概12.8GB，而2.4版本编译完后有12GB，加载到内存需要19GB。
1.15版本和2.4版本的核心实现原理是一致的。这儿使用Ubuntu 20.04版本，GDB 9.1版本。
git clone https://github.com/tensorflow/tensorflow.git git checkout -b r1.15 remotes/origin/r1.15 cd tensorflow |
按照前置需要软件包
sudo apt install python3-dev python3-pip pip install -U --user pip six 'numpy<1.19.0' wheel setuptools mock 'future>=0.17.1' 'gast==0.3.3' typing_extensions pip install -U --user keras_applications --no-deps pip install -U --user keras_preprocessing --no-deps |
配置TensorFlow
配置的时候能不编译的组件都选择N取消，调试核心框架不需要那些。
./configure |
安装编译工具：Bazel
参考https://docs.bazel.build/versions/0.26.0/install-ubuntu.html进行安装。也可点击bazel-0.26.1下载。
sudo chmod +x bazel-0.26.1-linux-x86_64 ./bazel-0.26.1-linux-x86_64 sudo ln -s bazel-0.26.1-linux-x86_64 /usr/bin/bazel |
编译TensorFlow
Build TensorFlow的debug版本，即可以用GDB Debug的版本：
Build的时候加上”–copt -g“:
通过查看任何一个.o文件来确认是否带有debug信息。例如gdb conv_ops_3d.pic.o验证，只要不出现No symbols则说明debug信息有。

编译之前需要应用一个patch避免编译错误：

关于debug level的解释：
-glevel Request debugging information and also use level to specify how much information. The default level is 2. Level 0 produces no debug information at all. Thus, -g0 negates -g. Level 1 produces minimal information, enough for making backtraces in parts of the program that you don't plan to debug. This includes descriptions of functions and external variables, but no information about local variables and no line numbers. Level 3 includes extra information, such as all the macro definitions present in the program. Some debuggers support macro expansion when you use -g3. |
