GNU GLOBAL Source Code Tag System浏览源码,很方便

本文介绍如何下载、编译并安装Global源码浏览器,包括配置环境使其能在任意路径下使用。文中还详细说明了如何结合Vim使用Global的强大功能,以及如何与Doxygen集成以增强代码文档化。

1、下载GLOBAL

http://www.gnu.org/software/global/global.html

http://www.gnu.org/software/global/globaldoc.html

2、编译安装

./configure --prefix=[your install dir]

make

make install


3、使用时注意先gtags后htags,如果直接执行htags会提示找不到gtags。


如果是在普通用户权限安装global,比如--prefix=/work/yourname/usr目录下,安装以后有如下目录:bin,include,lib,share,需将bin目录设置到~/.bashrc中,这样就可以在任何路径下使用gtags和htags了。


$cd your_src_dir
$gtags    # make tag files(GTAGS,GRTAGS,GSYMS)
$htags -v #make hypertext(HTML/)
这样,打开HTML下的index.html文件就可以开始浏览了。

"htags -fcFnvta"生成ghtml,并将它们放入apache的html目录。 -f(支持cgi动态搜索) -c(压缩生成html) -F(使用frame风格) -n(行号) -a(制作Function索引) -t(欢迎标题:随意输入"Welcome into kernel tour"). ",可以直接用htags -Fnvta或者gtags -v && htags -sofFnvaIht 'welcome to android eclair tour'

 

	$ gtags -v
	$ htags -sanohITvt 'Welcome to XXX source tour!'
	$ firefox HTML/index.html

	$ htags --suggest

	$ cflow --tree --format=posix *.[ch] >cflow.out
	$ htags --cflow=cflow.out

 

 

4、gtags+htags+vim非常强大的功能!!此工具下,再多的源码都变得渺小了!相见恨晚啊!哈哈!

$ cp /work/yourname/usr /share/gtags/gtags.vim $HOME/.vim/plugin
$ cp
/work/yourname/usr /share/gtags/gtags-cscope.vim $HOME/.vim/plugin


在使用前还需在src源码目录下执行gtags,否则,一样提示说找不到

Gtags-cscope: GTAGS not found.
Press ENTER or type command to continue

 

5、global+doxygen+firefox搭建

doxygen下载

http://www.stack.nl/~dimitri/doxygen/

 

HELP DOC:

http://www.gnu.org/software/global/globaldoc.html

You can use GLOBAL as the source browser of Doxygen.

Doxygen Release 1.4.3 or later has config option USE_HTAGS. When enabled in combination with SOURCE_BROWSER=YES, htags(1) is used as the source browser instead of Doxygen's own.

Here is an example.

(in source directory)
$ doxygen -g $ vi Doxyfile +---------------------------------
|...
|INPUT = .
|RECURSIVE = YES
|SOURCE_BROWSER = YES
|USE_HTAGS = YES

|...
$ doxygen
$ lynx html/index.html

<think>我们正在解决PX4编译过程中的CMake配置错误和Git版本标签格式错误。从错误日志中,我们可以看到几个关键问题: 1. **CMake错误**: - `list index: 1 out of range (-1, 0)` 和 `list index: 2 out of range (-1, 0)`: 列表索引越界,通常是因为尝试访问不存在的列表元素。 - `string sub-command REPLACE requires at least four arguments`: `string(REPLACE)`命令需要至少四个参数,而实际提供的参数不足。 - 多个`路径规格 ... 未匹配任何 git 已知文件`错误:表明Git子模块未正确初始化。 - `add_subdirectory given source ... which is not an existing directory`: 指定的子目录不存在。 - `get_target_property() called with non-existent target "uavcan"`: 尝试获取一个不存在的目标属性。 - 外部项目配置错误(`libmicroxrceddsclient_project`): 因为源代码目录不存在且没有提供下载信息。 2. **Git错误**: - 多个`error: 路径规格 ... 未匹配任何 git 已知文件`:这些是Git子模块路径,说明子模块没有正确初始化。 3. **Python模块错误**: - `/usr/bin/python3: Error while finding module specification for 'symforce.symbolic'`:缺少Python模块`symforce`。 4. **Make错误**: - `make[1]: *** 没有规则可制作目标“olddefconfig”。 停止。`:在构建NuttX配置时失败。 ### 解决方案步骤 #### 1. 初始化并更新Git子模块 许多错误是由于子模块未初始化导致的。运行以下命令来初始化并更新子模块: ```bash git submodule update --init --recursive ``` 如果遇到某些子模块更新失败,可以尝试单独初始化这些子模块,例如: ```bash git submodule update --init src/drivers/uavcan/libuavcan git submodule update --init src/modules/mavlink/mavlink git submodule update --init src/modules/uxrce_dds_client/Micro-XRCE-DDS-Client git submodule update --init src/lib/events/libevents git submodule update --init platforms/nuttx/NuttX/nuttx git submodule update --init platforms/nuttx/NuttX/apps ``` #### 2. 安装缺失的Python模块 错误提示缺少`symforce`模块,使用pip安装: ```bash pip3 install symforce ``` 如果系统中同时存在Python2和Python3,请使用`pip3`。 #### 3. 修复CMakeLists.txt中的错误 根据错误日志,我们需要检查以下文件中的问题: - **CMakeLists.txt (第129, 131, 132行)**: 这些行出现了列表索引越界和`string(REPLACE)`参数不足的错误。我们需要检查这些行附近的代码。 例如,第129行可能是这样的: ```cmake list(GET some_list 1 value) # 当列表长度不足2时,索引1会越界 ``` 修复方法:在访问列表元素前检查列表长度。 第132行可能是这样的: ```cmake string(REPLACE "old" "new") # 缺少输出变量和输入字符串 ``` 正确的格式应该是: ```cmake string(REPLACE "old" "new" output_variable input_string) ``` 由于我们没有具体的代码,建议根据错误提示的位置检查并修正。 - **src/drivers/uavcan/CMakeLists.txt (第93行)**: 添加子目录`libuavcan`,但该目录不存在。确保子模块`src/drivers/uavcan/libuavcan`已经正确初始化(步骤1)。 - **src/modules/uxrce_dds_client/CMakeLists.txt (第66行)**: 外部项目`libmicroxrceddsclient_project`配置错误。确保子模块`src/modules/uxrce_dds_client/Micro-XRCE-DDS-Client`已经初始化。如果该目录不存在,则可能需要手动克隆: ```bash cd src/modules/uxrce_dds_client git clone https://github.com/eProsima/Micro-XRCE-DDS-Client.git ``` #### 4. 修复NuttX配置错误 错误信息:`make[1]: *** 没有规则可制作目标“olddefconfig”。 停止。` 这通常是因为NuttX子模块没有正确初始化或构建环境不满足。确保已经按照步骤1初始化了`platforms/nuttx/NuttX/nuttx`和`platforms/nuttx/NuttX/apps`。然后尝试清理并重新构建: ```bash make clean make distclean ``` #### 5. 完整构建步骤 在修复上述问题后,按照PX4的标准构建步骤进行: ```bash # 进入PX4源码目录 cd /home/me/下载/px4-autopilot-1.15.4 # 初始化子模块(确保全部初始化) git submodule update --init --recursive # 创建构建目录并进入 mkdir build cd build # 运行CMake配置(指定目标) cmake .. -DCMAKE_BUILD_TYPE=MinSizeRel -DBOARD=px4_fmu-v5_default # 开始构建 make px4_fmu-v5_default ``` 或者使用PX4自带的构建脚本: ```bash make px4_fmu-v5_default ``` ### 注意事项 1. **权限问题**:确保对下载目录有读写权限。 2. **网络问题**:初始化子模块需要从GitHub克隆,确保网络畅通。 3. **工具链版本**:确保使用支持的工具链(如GCC 9.2.1 arm-none-eabi)。 4. **环境变量**:设置必要的环境变量,例如`PATH`包含arm-none-eabi工具链。 ### 相关问题 §§相关问题§§ 1. 如何解决Git子模块初始化失败的问题? 2. 在CMake中如何正确处理列表操作以避免索引越界? 3. 如何安装和配置PX4开发所需的Python环境? 4. 如何修复PX4编译过程中出现的NuttX配置错误? 5. 如何正确设置CMake的`string(REPLACE)`命令参数?</think>针对PX4编译过程中的CMake配置错误和Git版本标签格式问题,以下是系统性的修复方案: ### 一、核心问题修复 #### 1. **Git子模块初始化失败** ```bash # 递归初始化所有子模块 git submodule update --init --recursive # 手动修复关键缺失模块 git submodule add https://github.com/PX4/NuttX platforms/nuttx/NuttX/nuttx git submodule add https://github.com/PX4/libuavcan src/drivers/uavcan/libuavcan ``` #### 2. **CMake列表索引越界修复 检查`CMakeLists.txt`第129行附近代码: ```cmake # 原始错误代码示例 list(GET MY_LIST 1) # 当列表为空时导致越界 # 修复方案:增加长度检查 list(LENGTH MY_LIST list_len) if(list_len GREATER 1) list(GET MY_LIST 1 value) endif() ``` #### 3. **string(REPLACE)参数错误修复** ```cmake # 错误示例(缺少参数) string(REPLACE "old" "new") # 正确格式(需4个参数): string(REPLACE "old" "new" OUTPUT_VAR INPUT_STR) # 实际应用示例 string(REPLACE "git@" "https://" SAFE_URL ${ORIGIN_URL}) ``` #### 4. **Git版本标签格式问题** ```bash # 规范化本地标签格式 git tag -d $(git tag -l) # 删除错误标签 git fetch --tags --force # 重新获取远程标签 # 验证标签格式 git describe --tags --always # 应显示类似v1.15.4的格式 ``` #### 5. **Python依赖修复** ```bash # 安装缺失的symforce模块 pip3 install symforce # 验证Python路径 export PYTHONPATH=$PYTHONPATH:/path/to/px4/symforce ``` ### 二、完整构建流程 ```bash # 1. 清理无效构建 rm -rf build/ CMakeCache.txt # 2. 设置工具链路径 export ARM_NONE_EABI_PATH=/usr/bin/arm-none-eabi # 3. 配置CMake(关键参数) cmake -B build -S . \ -DCMAKE_MODULE_PATH=$(pwd)/cmake \ -DGIT_EXECUTABLE=$(which git) \ -DPYTHON_EXECUTABLE=$(which python3) \ -DBOARD=px4_fmu-v5_default # 4. 构建固件 cmake --build build --target px4_fmu-v5_default ``` ### 三、关键配置说明 1. **CMake模块路径**: ```cmake set(CMAKE_MODULE_PATH ${CMAKE_SOURCE_DIR}/cmake ${CMAKE_SOURCE_DIR}/cmake/Modules ) # 确保优先搜索项目内模块[^1] ``` 2. **Git子模块映射**: ```bash # 在.gitmodules中添加 [submodule "NuttX"] path = platforms/nuttx/NuttX/nuttx url = https://github.com/PX4/NuttX ``` 3. **交叉编译工具链**: ```cmake set(CMAKE_C_COMPILER ${ARM_NONE_EABI_PATH}-gcc) set(CMAKE_CXX_COMPILER ${ARM_NONE_EABI_PATH}-g++) ``` ### 四、常见错误预防 1. **路径规范**: - 使用`${CMAKE_SOURCE_DIR}`替代相对路径 - Git路径需符合RFC 3986标准[^2] 2. **环境隔离**: ```bash python3 -m venv px4_env source px4_env/bin/activate pip install -r requirements.txt ``` 3. **构建验证**: ```bash # 检查固件生成 ls build/px4_fmu-v5_default/px4_fmu-v5_default.px4 ``` > **注**:若仍遇`git@github.com`路径错误,使用全局替换: > ```bash > find . -type f -exec sed -i 's/git@github.com:/https:\/\/github.com\//g' {} \; > ```
