Question

我想使用需要lapack的软件才能正确编译。但我无法在Mac上进行lapack工作。

http://www.netlib.org/lapack/

我正在尝试安装lapack-3.7.1

我输入make，此消息到达：

 make: *** No rule to make target `lsame.o', needed by `testlsame'.  Stop.

我试图修改make.inc，但似乎我在互联网上看到的一些说明没有更新。我看到我们必须将PLAT更改为PLAT = _DARWIN。

http://www.commonmediainc.com/2008/03/24/building-lapack-and-rubys-linalg-on-mac-os-x/

我在make.inc文件中看不到它。

是否有一些分步说明来安装lapack？

make.inc文件：

#  Modify the FORTRAN and OPTS definitions to refer to the compiler
#  and desired compiler options for your machine.  NOOPT refers to
#  the compiler options desired when NO OPTIMIZATION is selected.

#  Note: During a regular execution, LAPACK might create NaN and Inf
#  and handle these quantities appropriately. As a consequence, one
#  should not compile LAPACK with flags such as -ffpe-trap=overflow.

#  For gfortran compiler:  SECOND and DSECND will use a call to the

TIMER = INT_ETIME
#  If your Fortran compiler does not provide etime (like Nag Fortran
#  Compiler, etc...) SECOND and DSECND will use a call to the
#  INTERNAL FUNCTION CPU_TIME
#TIMER = INT_CPU_TIME
#  If none of these work, you can use the NONE value.
#  In that case, SECOND and DSECND will always return 0.
#TIMER = NONE

我已经尝试过Homebrew，但它无法正常工作：

brew install lapack

Error: No available formula with the name "lapack" 
==> Searching for similarly named formulae...
Error: No similarly named formulae found.
==> Searching taps...
This formula was found in a tap:
homebrew/science/lapack-manpages
To install it, run:
  brew install homebrew/science/lapack-manpages

但即使brew install homebrew/science/lapack-manpages也无效......

Homebrew 0.9.9 (git revision 1158; last commit 2016-07-20) Homebrew/homebrew-core (git revision f7372; last commit 2016-07-20)

Answer 1

macOS的较新版本（包括10.11）随附vecLib中包含的LAPACK实现，该实现包含在macOS中。因此，如果您的软件支持vecLib，则可能根本不需要安装LAPACK。

如果您需要安装单独的LAPACK，它现在可以作为Homebrew核心中的Homebrew公式使用。因此brew install lapack现在可以正常工作。

Homebrew lapack公式当前包含适用于OS X 10.11的预构建二进制“瓶”，因此安装应该简单快捷。

Answer 2

尝试

Brew cask install lapack

或

Brew cask install Mac ports;port install lapack

是否可以在Mac OSX 10.11上安装lapack？
