I have a design that uses imported C functions, and they depend on dynamic libraries, which therefore needs
-lflags to be passed to the linker. When I tried using BSC to generate a Verilator simulation executable (withbsc -vsim verilator -e), Verilator failed with errors about missing references, because it was not including those libraries. I discovered that thebsc_build_vsim_verilatorscript wasn't passing those linker flags to Verilator.I patched the script to pass
BSC_C_LIB_PATH,BSC_CLINK_OPTS, andBSC_C_LIBSasLDFLAGS. This fixed my situation, although I was only usingBSC_C_LIBS, so I haven't tested on an example that has the other two kinds of flags.
