gcc - 与 OS X 10.10.2 的 "__mpf_struct"相关的 undefined symbol 错误

Question

我正在尝试编译一个程序

https://github.com/davidsd/sdpb

在 OS X 10.10.2 上使用 gcc-4.9、boost 1.57.0、gmp-6.0.0a 和 mpfr-3.1.2，但我不断收到似乎与 gmp 和 mpfr 包相关的错误。我知道有人在 10.9.5 上成功编译。有人可以建议修复吗？

看起来排序有误。库应该遵循对象文件

当我把它固定到

它在我的系统上链接没有错误

所以在Makefile中，将链接命令改为

$(RESULT): $(OBJECTS)
    $(CC) $(CFLAGS) -o $@ $^ $(LIBS)
