Я только что реализовал распределенную версию проекта базы данных с использованием gRP C. Когда я пытался сделать с моим make-файлом, я продолжал получать неопределенные ссылочные ошибки с protobuf и gRP C. Части выходов make ниже. Я включил только его часть из-за ограничений по количеству слов.

Я читал некоторые другие предыдущие сообщения, в которых говорилось, что это вызвано отсутствием линковки библиотеки protobuf, но я включил его в LDFLAGS. Файл сборки находится ниже.
CC=g++
CFLAGS=-Wall -g -std=c++11
.SUFFIXES: .o .cpp .h
SRC_DIRS = ./ ./benchmarks/ ./concurrency_control/ ./storage/ ./system/ ./transport/ ./utils/ ./grpc/ ./grpc_system/
INCLUDE = -I. -I./benchmarks -I./concurrency_control -I./storage -I./system -I./transport -I./utils -I./grpc -I./grpc_system
CFLAGS += $(INCLUDE) -D NOGRAPHITE=1 -O3 -g -ggdb
LDFLAGS = -Wall -L./libs -pthread -lrt -std=c++0x -O3 -ljemalloc -lprotobuf
LDFLAGS += $(CFLAGS)
CPPS = $(foreach dir, $(SRC_DIRS), $(wildcard $(dir)*.cpp))
OBJS = $(CPPS:.cpp=.o)
DEPS = $(CPPS:.cpp=.d)
all:rundb
rundb : $(OBJS)
$(CC) -o $@ $^ $(LDFLAGS)
-include $(OBJS:%.o=%.d)
%.d: %.cpp
$(CC) -MM -MT $*.o -MF $@ $(CFLAGS) $<
%.o: %.cpp %.d
$(CC) -c $(CFLAGS) -o $@ $<
.PHONY: clean
clean:
rm -f rundb *.o */*.o *.d */*.d
Я думал, что LDFLAGS = -Wall -L./libs -pthread -lrt -std=c++0x -O3 -ljemalloc -lprotobuf решит эту проблему, но этого не произошло.
