C++编译-x86_64上的GSL

C++ compile - GSL on x86_64

本文关键字：上的 GSL 编译 -x86 C++      更新时间：2023-10-16

我正在尝试编译以下代码：http://www-personal.umich.edu/~mejn/dcbm/KLOptimization.cpp

但我从g++得到以下错误消息：

> Undefined symbols for architecture x86_64:   "_gsl_rng_uniform_int",
> referenced from:
>       Initialize()     in ccDEqovL.o

我有MacBook Air，运行iOS 10.7.3。g++是i686-apple-darwin11-llvm-g++-4.2。

我使用"brew-install-GSL"安装了GSL，它给出了以下输出：

==> Downloading http://ftpmirror.gnu.org/gsl/gsl-1.15.tar.gz

==> ./configure --prefix=/usr/local/Cellar/gsl/1.15
==> make
==> make install
Warning: m4 macros were installed to "share/aclocal".
Homebrew does not append "/usr/local/share/aclocal"
to "/usr/share/aclocal/dirlist". If an autoconf script you use
requires these m4 macros, you'll need to add this path manually.
==> Summary

您似乎忘记了链接GSL库。只需添加-lgsl，它就可以工作了（假设gsl在库路径中）。
