- Install autoconf, automake, pkg-config, libtool and texinfo.
brew install autoconf automake pkg-config libtool texinfo
下载代码：
git clone --recursive https://github.com/riscv/riscv-openocd.git
执行顺序
进入到riscv-openocd目录下，执行：
./bootstrap
./configure
make
make install
常见问题
问题1： AC_PROG_CC_C99 告警2
在执行./bootstrap的时候可能会报warning
+ aclocal --warnings=all
+ glibtoolize --automake --copy
+ autoconf --warnings=all
+ autoheader --warnings=all
+ automake --warnings=all --gnu --add-missing --copy
Setting up submodules

configure.ac:38: warning: The macro `AC_PROG_CC_C99' is obsolete.
configure.ac:38: You should run autoupdate.
./lib/autoconf/c.m4:1659: AC_PROG_CC_C99 is expanded from...
configure.ac:38: the top level
Bootstrap complete. Quick build instructions:
./configure ....
这里提示configure.ac第38行有告警。开始以为是当前目录下的configure.ac文件有不兼容的问题。其实注释掉openocd-code/src/jtag/drivers/libjaylink/configure.ac.文件的第38行就可以了。
修改后重新执行，log显示不再有告警：
+ aclocal --warnings=all
+ glibtoolize --automake --copy
+ autoconf --warnings=all
+ autoheader --warnings=all
+ automake --warnings=all --gnu --add-missing --copy

问题2: texinfo 版本不匹配
brew install texinfo 后执行
export PATH=“/opt/homebrew/opt/texinfo/bin:$PATH”
问题2: libtool版本不匹配
系统目录下/usr/bin/libtool版本较旧，我的是2.4.6
用brew install libtool后会安装新的libtool，版本2.4.7，需要用环境变量执行新安装的目录。
执行下面命令可以看到安装后的信息。
> brew info libtool
...
If you need to use these commands with their normal names, you
can add a "gnubin" directory to your PATH from your bashrc like:
PATH="/opt/homebrew/opt/libtool/libexec/gnubin:$PATH"
注意添加path后立即执行make是不生效的。原因是在config阶段会copy libtool到当前目录下，后面make阶段调用的都是当前目录下的libtool。这时需要手动删除当前目录下的libtool，然后重新执行./configure
问题3: 编译错误
编译产生如下错误：
src/flash/nor/dsp5680xx_flash.c:48:11: error: variable 'offset' set but not used [-Werror,-Wunused-but-set-variable]
uint32_t offset = HFM_FLASH_BASE_ADDR;
^
1 error generated.
看起来是可以waive掉的问题。打开configure.ac文件，找到Werror的地方，注释的这个选项。如下：
AS_IF([test "x${gcc_werror}" = "xyes"], [
#GCC_WARNINGS="${GCC_WARNINGS} -Werror"
GCC_WARNINGS="${GCC_WARNINGS}"
])
验证一下
