c - 针对 libopcodes 编译时出错

Question

我正在关注 here 中的一些代码如下:

OP 说您可以使用 -lbfd -lopcodes 进行链接。

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:

makegcc ./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':/home/abuild/rpmbuild/BUILD/binutils-2.24/build-dir/opcodes/../../opcodes/arm-dis.c:2927: undefined reference to `floatformat_ieee_single_little'/home/abuild/rpmbuild/BUILD/binutils-2.24/build-dir/opcodes/../../opcodes/arm-dis.c:2927: undefined reference to `floatformat_to_double'/usr/lib64/gcc/x86_64-suse-linux/4.8/../../../../lib64/libopcodes.a(m68k-dis.o): In function `print_insn_arg':/home/abuild/rpmbuild/BUILD/binutils-2.24/build-dir/opcodes/../../opcodes/m68k-dis.c:1103: undefined reference to `floatformat_m68881_ext'/home/abuild/rpmbuild/BUILD/binutils-2.24/build-dir/opcodes/../../opcodes/m68k-dis.c:1103: undefined reference to `floatformat_to_double'/home/abuild/rpmbuild/BUILD/binutils-2.24/build-dir/opcodes/../../opcodes/m68k-dis.c:1099: undefined reference to `floatformat_ieee_double_big'/home/abuild/rpmbuild/BUILD/binutils-2.24/build-dir/opcodes/../../opcodes/m68k-dis.c:1099: undefined reference to `floatformat_to_double'/home/abuild/rpmbuild/BUILD/binutils-2.24/build-dir/opcodes/../../opcodes/m68k-dis.c:1095: undefined reference to `floatformat_ieee_single_big'/home/abuild/rpmbuild/BUILD/binutils-2.24/build-dir/opcodes/../../opcodes/m68k-dis.c:1095: undefined reference to `floatformat_to_double'collect2: error: ld returned 1 exit statusMakefile:4: recipe for target 'bfd_se' failedmake: *** [bfd_se] Error 1

我需要添加哪些其他标志才能编译该程序？我看到错误与不同的体系结构有关，但我并没有尝试交叉编译。

谢谢!

objdump --version(它使用 libbfd 和 libopcodes)

大多数时候 libbfd 和 libopcodes 不会作为标准发行版中的共享库出现(因为它们不打算链接到)。您必须链接到静态库(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，请尝试:

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
