在 Mac 10.6.3 上使用 gsl

我最近有一个使用 GSL 的项目。我在 Mac 10.6.3 上安装了 GSL 包之后。我无法编译我的代码。

gsl lib位于/usr/local/lib，头文件位于/usr/local/。

当我编译代码时，出现以下错误。如果我没有在makefile中指定“-m32”，它仍然会给出相同的错误，只需将“i386”更改为“x86_64”即可。谁能帮助我吗？

谢谢你！

#include <gsl/gsl_vector.h>
#include <gsl/gsl_multiroots.h>

顺便问一下，我应该像上面那样包含 gsl 吗？实际上我对编程很陌生。

构建代码：

CC = g++
OPT = -pg -g -I../include -L../libs -I../../Matrix-1.0/include -I../../bessel-1.1/include  -L../../Matrix-1.0/libs -L../../bessel-1.1/libs -L/usr/local/lib
LIBS =  -lfmm -lssi -lsparse -lbessel -lg2c -lgfortran -lgsl
.SUFFIXES : .o .cpp 

test_guide: test_guide.o
  ${CC} -o $@ ${OPT} test_guide.o ${LIBS}

原文

I recently have a project using GSL. After I installed the GSL package on Mac 10.6.3. I cannot compile my code.

The gsl lib is located at /usr/local/lib, and the head file located at /usr/local/.

When I compile my code I get the the following error. If I do not specify "-m32" in the makefile, it still gives the same error, just change "i386" to "x86_64". Can anyone help me?

Thank you!

#include <gsl/gsl_vector.h>
#include <gsl/gsl_multiroots.h>

By the way, should I include gsl like the above? actually I am quite new to programming.

我不确定，但我认为您还需要链接 GSL 的 BLAS 库。您的 x86_64 未定义引用似乎也暗示了这一点（blas.o 是我正在进行的提示）。只需添加

-lgslcblas

到您的 LIBS 变量即可。

I'm not sure, but I think you'll need to link with GSL's BLAS library as well. Your x86_64 undefined reference seems to imply as much (blas.o is the hint I'm going on). Just add
