Link error

[Fresher14]

Hi,
I tried this nice project in a unix environment.
It compiles but I had to use additional compilation flags:
-std=c++11
-D_GLIBCXX_USE_CXX11_ABI=0

Now the link error:
g++ -O2 -L*** -L./lib -L../../isa_sim obj/riscv_tcm_top_rtl.o obj/main.o -o build/test.x -lsystemc -lisa_sim -lsyscverilated -lelf -lbfd
obj/main.o: In function testbench::process()': main.cpp:(.text._ZN9testbench7processEv[_ZN9testbench7processEv]+0x41): undefined reference to cosim::attach_cpu(std::string, cosim_cpu_api*)'
main.cpp:(.text._ZN9testbench7processEv[_ZN9testbench7processEv]+0x8a): undefined reference to cosim::attach_mem(std::string, cosim_mem_api*, unsigned int, unsigned int)' ld: build/test.x: hidden symbol bfd_check_format_matches' in /usr/lib64/libbfd.a(format.o) is referenced by DSO
ld: final link failed: Bad value

Looking inside the content of isa_sim library, it seems to be there though:
0000000000009e60 T cosim::attach_cpu(std::__cxx11::basic_string<char, std::char_traits, std::allocator >, cosim_cpu_api*)
0000000000009f30 T cosim::attach_mem(std::__cxx11::basic_string<char, std::char_traits, std::allocator >, cosim_mem_api*, unsigned int, unsigned int)

Hi,
i have met the same proplem. you can try this :
cd ../../isa_sim
make clean // --- to clear the *.o file under the obj/riscv-sim path
make
cd ../top_tcm_axi/tb
make
