r2pm -ci r2ghidra 时报错：checking pkg-config flags for r_core... no
参考网址：
sys/python.sh fails with `checking pkg-config flags for r_core... no` · Issue #1943 · radareorg/radare2 · GitHub
进入目录/root/.local/share/radare2/r2pm/git/r2ghidra查看configure文件，查找报错位置
执行指令 ：
# pkg-config --cflags r_core
Package libxxhash was not found in the pkg-config search path.
Perhaps you should add the directory containing `libxxhash.pc'
to the PKG_CONFIG_PATH environment variable
Package 'libxxhash', required by 'r_hash', not found
Package 'libxxhash', required by 'r_hash', not found
Package 'libxxhash', required by 'r_hash', not found

Package 'libxxhash', required by 'r_hash', not found
Package 'libxxhash', required by 'r_hash', not found
Package 'libxxhash', required by 'r_hash', not found
安装 libxxhash
apt-get install libxxhash-dev
最后进行：r2pm -ci r2ghidra 进行安装时还是报错：

安装r2dec插件，使用pdd反编译
r2pm install r2dec
[0x08048430]> pdd @main
/* r2dec pseudo code output */
/* /root/test/ret2win32 @ 0x8048546 */
#include <stdint.h>int32_t main (char ** argv) {int32_t var_4h;ecx = &argv;eax = stdout;setvbuf (eax, 0, 2, 0);puts ("ret2win by ROP Emporium");puts ("x86\n");pwnme ();puts ("\nExiting");eax = 0;ecx = var_4h;esp = ecx - 4;return eax;
}
终于有时间了接着安装r2ghidra插件，接着上面报错:
找到r2ghidra的默认的路径：~/.local/share/radare2/r2pm/git/r2ghidra
在./src路径下找到anal_ghidra_plugin.c文件，按照“has no member named”报错，找到一篇文档：C语言，C++编译遇到问题:has no member named ''XXX‘_ZDF19的博客-CSDN博客
文档中找到的两个方法都没有用，还要自己进行解决，估计是“cpus”没有定义，查看源文件

把29行的#endif下移如下，搞定
