I’m trying to compile nvinfer_custom_lpr_parser. HOwever the below error comes while compiling using the make file:

CC:= g++

CFLAGS:= -Wall -Werror -std=c++11 -shared -fPIC -Wno-error=deprecated-declarations

CFLAGS+= -I/opt/nvidia/deepstream/deepstream/sources/includes

LIBS:= -lnvinfer -lnvparsers

LFLAGS:= -Wl,--start-group $(LIBS) -Wl,--end-group

SRCFILES:= nvinfer_custom_lpr_parser.cpp
TARGET_LIB:= libnvdsinfer_custom_impl_lpr.so

all: $(TARGET_LIB)

$(TARGET_LIB) : $(SRCFILES)
	$(CC) -o $@ $^ $(CFLAGS) $(LFLAGS)

clean:
	rm -rf $(TARGET_LIB)

error:

/usr/bin/ld: cannot find -lnvparsers: No such file or directory
collect2: error: ld returned 1 exit status
make: *** [Makefile:16: libnvdsinfer_custom_impl_lpr.so] Error 1

Any help is highly appreciated @junshengy

While installing Tensorrt I got this:

For TRT-10.x, libnvparsers.so has been removed. Please delete the shared library in the Makefile.
