针对 libopcodes 编译时出错

Question

我正在遵循 here 中的一些代码，如下所示：

OP 说您可以 link 和 -lbfd -lopcodes。

但是，对于 OpenSuSE，我发现对于 libbfd，我需要 -lbfd -liberty -lz -ldl

尝试编译时，这是我的结果：

make

gcc ./main.c -lbfd -liberty -lz -ldl -lopcodes -g -o bfd_se

/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64/libopcodes.a(arm-dis.o): In function `print_insn_neon':

collect2: error: ld returned 1 exit status
Makefile:4: recipe for target 'bfd_se' failed
make: *** [bfd_se] Error 1

我还需要添加哪些标志才能编译此程序？我看到错误与不同的体系结构有关，但我没有尝试交叉编译。

谢谢！

大多数时候 libbfd 和 libopcodes 不会作为标准发行版中的共享库出现（因为它们不应该被 link 编辑）。您必须 link 到静态库（libbfd.a 和 libopcodes.a）或重新编译您的分发包并在其中包含共享库（.so 文件）。

所以，为了说清楚，试试：

gcc ./main.c -liberty -lz -ldl -g -o bfd_se /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64/libopcodes.a /usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64/libbfd.a
