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：

pdg反编译指令暂时搞不定。

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;
}
