C编译错误：架构x86_64的未定义符号：“_stringAdd”

时间：2016-04-22 09:09:02

标签： c macos compiler-errors

我正在尝试构建i8086emu这是一个跨平台模拟器。

我在mac`下 我按照自述文件的说法做了。

当我在make之后运行./configure命令时，我收到了错误

Undefined symbols for architecture x86_64:
  "_stringAdd", referenced from:
      _i8086errorEx in i8086error.o
      _i8086warningEx in i8086error.o
      _i8086clearLog in i8086error.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[2]: *** [devices/i8086vga.so] Error 1
make[1]: *** [all] Error 2
make: *** [all] Error 2

当然，我已经google了解决方案。但是我没有得到有用的答案。

似乎我可以通过修改Makefile来修复此问题。

有人能给我一个提示吗？

修改

答案 0 :(得分：1)

在Makefile.in中可能出现了错误：

第130-131行，写道：

devices/i8086vga.so: devices/i8086vga.c i8086error.o i8086messages.o
    if [ 1 -eq 1 ]; then gcc ${CFLAGS} ${WIN32} -shared -fPIC devices/i8086vga.c i8086error.o i8086messages.o -o devices/i8086vga.so -lpthread `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0`;fi;

我认为i8086util.o遗失了。尝试替换（i8086util.o出现在两行中）：

devices/i8086vga.so: devices/i8086vga.c i8086error.o i8086messages.o i8086util.o
    if [ 1 -eq 1 ]; then gcc ${CFLAGS} ${WIN32} -shared -fPIC devices/i8086vga.c i8086error.o i8086messages.o i8086util.o -o devices/i8086vga.so -lpthread `pkg-config --cflags gtk+-2.0` `pkg-config --libs gtk+-2.0`;fi;

修改

完成此操作后，重新运行./configure，然后生成
