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
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：

anal_ghidra_plugin.c:28:10: error: ‘RAnalPlugin’ {aka ‘struct r_anal_plugin_t’} has no member named ‘cpus’28 |         .cpus = "6502,6805,8051,arm,avr,cr16,dalvik,hppa,java,m68k,m8c,mips,mcs96,msp430,pic24,ppc,sh,sparc,stm8,tricore,toy,v850,wasm,x86,z80",|          ^~~~

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;
}

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

 27  #if R2_VERSION_NUMBER >= 5060928          .endian = R_SYS_ENDIAN_LITTLE | R_SYS_ENDIAN_BIG,29 #endif30          .cpus = "6502,6805,8051,arm,avr,cr16,dalvik,hppa,java,m68k,m8c,mips,mcs96,msp430,pic24,ppc,sh,sparc,stm8,tricore,toy,v850,wasm,x86,z80",31 

查看当前系统的r2版本

 r2 -V
5.5.0  r2
5.5.0  r_anal
5.5.0  r_lib
5.5.0  r_egg
5.5.0  r_asm
5.5.0  r_bin
5.5.0  r_cons
5.5.0  r_flag
5.5.0  r_core

应该是大于50609

把29行的#endif下移如下，搞定

 27  #if R2_VERSION_NUMBER >= 5060928          .endian = R_SYS_ENDIAN_LITTLE | R_SYS_ENDIAN_BIG,2930          .cpus = "6502,6805,8051,arm,avr,cr16,dalvik,hppa,java,m68k,m8c,mips,mcs96,msp430,pic24,ppc,sh,sparc,stm8,tricore,toy,v850,wasm,x86,z80",31  #endif
