摘要......

我正在尝试编译example.cpp arma.sourceforge.net/docs.html#example_prog

我尝试用lapack和blas编译和链接armadillo。我总是得到同样的错误。返回此消息

ld.exe: cannot find -llapack
ld.exe: cannot find -lblas

我确认以下所有路径都是正确的并运行以下内容。

g++ example.cpp -o example -O1  -I..\..\lapackblas_headers\lapack -I..\..\lapackblas_headers\blas  -I..\include

-L .... \ lapackblas_MD_debug -llapack -lblas

返回此消息

ld.exe: cannot find -llapack
ld.exe: cannot find -lblas

这

f:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -llapack
f:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -lblas

collect2：ld返回1退出状态

我下载了LAPACK和BLAS的预编译版本从...下载 http://www.fi.muni.cz/~xsvobod2/misc/lapack/

我按照这里的说明进行操作

https://sourceforge.net/projects/arma/files/latest/download
http://sourceforge.net/projects/arma/files/armadillo-3.800.0.tar.gz
file:///M:/YDrive/All_Economics/eclipse_workspace/armadillo-3.800.0/README.txt

我有lapack和blas库

ls -alrt ../../lapackblas-MD-debug

我尝试用lapack和blas编译和链接armadillo。我总是得到同样的错误。

M:
cd \YDrive\All_Economics\eclipse_workspace\armadillo-3.800.0\examples

M:\YDrive\All_Economics\eclipse_workspace\armadillo-3.800.0\examples>

我尝试了相对路径

g++ example.cpp -o example -O1  -I..\..\lapackblas_headers\lapack -I..\..\lapackblas_headers\blas  -I..\include 

-L..\..\lapackblas_MD_debug -llapack -lblas

我尝试了绝对路径

g++ example.cpp -o example -O1  -IM:\YDrive\All_Economics\eclipse_workspace\lapackblas_headers\lapack  

-IM:\YDrive\All_Economics\eclipse_workspace\lapackblas_headers\blas  

-IM:\YDrive\All_Economics\eclipse_workspace\armadillo-3.800.0\include 

-LM:\YDrive\All_Economics\eclipse_workspace\lapackblas_MD_debug -llapack -lblas

在所有情况下，返回的信息都在这里

ld.exe: cannot find -llapack
ld.exe: cannot find -lblas

f:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -llapack
f:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -lblas
collect2: ld returned 1 exit status

有什么想法吗？

谢谢。安德烈米库莱克 Andre_Mikulec@Hotmail.com

Answer 1

我找到了部分解决方案。

g++ -o example example.cpp ..\..\lapackblas_MD_debug\blas_win32_MDd.dll ..\..\lapackblas_MD_debug\lapack_win32_MDd.dll -O1  -I..\..\lapackblas_headers\lapack -I..\..\lapackblas_headers\blas  -I..\include

此页面解释了它。 http://www.mingw.org/wiki/MSVC_and_MinGW_DLLs

基本上，我需要在主程序

之后直接在命令行上指定DLL文件

另外，要完成解决方案，我必须安装（尚未）依赖的DLL 来自英特尔Fortran编译器（或30天eval）。

这个页面（我获得了DLL）解释了它（在细则中）。

LAPACK & BLAS precompiled binaries for Win32 platform
http://www.fi.muni.cz/~xsvobod2/misc/lapack/

Armadillo C ++和BLAS以及ATLAS在mingw32下找不到lapack blas
