我正在尝试构建 i8086emu 这是一个跨平台模拟器。
我在mac下` 我按照自述文件所说的做了。
当我在 ./configure 之后运行 make 命令时，出现错误
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，我已经用谷歌搜索了解决方案。但是我没有得到有用的答案。
看来我可以通过修改Makefile来解决这个问题。
有人可以给我提示吗？

最佳答案
在 Makefile.in 中可能发生了错误:
第130-131行，这样写:
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 丢失了。尝试替换为(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;
编辑
完成此操作后，重新运行 ./configure，然后 make
