c++ - Multiple definition error while linking: multiple definition of `typeinfo name

Question

I'm very new to c++ (my background is in python and java) and I'm trying to build the cockroachdb project on a raspberry pi. To build I ran the command make build -j1.

However I am getting the error below:

[  0%] Linking CXX shared library lib/libgeos.so
/usr/bin/ld: CMakeFiles/geos.dir/src/noding/BasicSegmentString.cpp.o:(.rodata+0x0): multiple definition of `typeinfo name for geos::noding::BasicSegmentString'; CMakeFiles/geos.dir/src/inlines.cpp.o:(.rodata+0x6c): first defined here

make[1]: *** [Makefile:418: geos_c] Error 2
make: *** [Makefile:757: libgeos_inner] Error 2

I went to CMakeFiles/geos.dir/build.make and on line 4569 I see: $(CMAKE_COMMAND) -E cmake_link_script CMakeFiles/geos.dir/link.txt --verbose=$(VERBOSE) but I don't really know what is wrong and what to do next to fix this.

Can someone help out a c++ beginner? Thank you.

显然这个问题已经存在了一段时间。解决方法是按照该页面上的说明提供 -DDISABLE_GEOS_INLINE=ON。
各个开关在GEOS 网站上的名称不同，但这似乎是过时的信息并且不起作用。
