I am writing C++ codes and wanted to link an external library, matplot++, with my project. I haven't got used to CMake so I write commands in Makefile. I am confused for the errors I have encoutered so far, finally laying on LNK2019. Most of LNK2019 answers don't fit me and the situation so far. I don't think it's a problem of the library. Could the experts on MSVC help me out?
Btw I tried to link the .lib static, only to produce more errors so I have to use /MD to bypass half of the errors. I have checked that both my cl.exe and .lib are 32-bit (x86). The environment variable INCLUDE and LIB link paths are set.
# Command:
cl /MD test.cpp matplot.lib /std:c++17 /Fe:test.exe /FI xxx.hpp /FI xxx.cpp
Platform: Win10
Compiler: MSVC from VS2019 (cl.exe x86)
Lib: matplot.lib (x86)
