我正在尝试使用gsl库进行一些随机数生成。我有以下生成文件GSL中未定义的引用，可能的链接错误？
CC = g++
#CFLAGS = -Wall -O2
CFLAGS = -g -Wall
LDFLAGS = -Lgsl/lib -lgsl -lgslcblas -lm
INCLDIRS = -Igsl/include
RAND_TARGET = rand
HM_TARGET = hitormiss
NU_TARGET = nonuniform
MC1D_TARGET = mc1d
RAND_SRCS = rand.cc generators.cc EX_RNGs.cc LC_RNGs.cc util.cc RNG_factory.cc
HM_SRCS = hitormiss.cc generators.cc EX_RNGs.cc LC_RNGs.cc discrep.cc util.cc sphere.cc
NU_SRCS = nonuniform.cc generators.cc LC_RNGs.cc EX_RNGs.cc util.cc
MC1D_SRCS = mc1d.cc generators.cc LC_RNGs.cc
RAND_OBJS = ${RAND_SRCS:.cc=.o}
HM_OBJS = ${HM_SRCS:.cc=.o}
NU_OBJS = ${NU_SRCS:.cc=.o}
MC1D_OBJS = ${MC1D_SRCS:.cc=.o}
CLEANFILES = $(RAND_OBJS) $(RAND_TARGET) \
$(HM_OBJS) $(HM_TARGET) \
$(NU_OBJS) $(NU_TARGET) \
$(MC1D_OBJS) $(MC1D_TARGET) \

VERYCLEANFILES = randdata.txt \

和下面的头文件
#ifndef _H_EX_RNGS
#define _H_EX_RNGS
#include <cstdlib>
#include <cmath>
#include <iostream>
#include "generators.h"
#include "gsl/include/gsl/gsl_rng.h"
namespace generators {
class GSL_RAND: public RNG {
gsl_rng *r;
public:
GSL_RAND();
virtual unsigned int nextInt();
/** Base deconstructor. */
virtual ~GSL_RAND() {}
virtual void setSeed(unsigned int seed);
virtual unsigned int getMaximum();
};
};
#endif
运行生成文件时，我为每一个呼叫到GSL功能的问题是
EX_RNGs.o: In function `generators::GSL_RAND::GSL_RAND()':
/home/school/rngmc/EX_RNGs.cc:34: undefined reference to `gsl_rng_rand'
/home/school/rngmc/EX_RNGs.cc:34: undefined reference to `gsl_rng_alloc'
和类似的错误在节目中。从我读过的内容来看，未定义的引用错误通常是由于链接到必要文件时出错造成的。地图gsl（我链接到makefile中）和makefile在同一张地图上，所以这应该没问题吧？我看不出我犯了什么错误？预先感谢您的帮助。
编辑：我不知道这是否会有所帮助，但
LDFLAGS = -L/usr/local/lib -lgsl -lgslcblas -lm
INCLDIRS = -I/usr/local/include
中生成文件LDFLAGS和INCLDIRS线更换也给出了同样的错误，即使GSL库还存在于USR /本地目录。
我是否需要为我的文章添加额外信息？或者这种类型的问题是不允许的？ – user47693
