如何编译lapack以便在安装八度音程时可以正确使用?

问题描述 投票:7回答:2

我正在尝试在运行redhat + IBM LSF的集群中从源安装最新的octave 3.8.1。除了我自己的家庭目录之外,我没有其他任何地方的写访问权限,这就是我必须从源代码安装八度音程的原因。集群提供的blas和lapack不起作用,所以我必须自己构建它们。我现在已经完成了编译blas和lapack并传递了./configure,但是当我运行make时,报告错误如下:

这些是我用来建立自己的BLASLAPACK的步骤。 BLAS的来源在~/src/BLAS,而LAPACK的来源在~/src/lapack-3.5.0,而倍频程3.8.1的来源在~/src/octave-3.8.1。只有两个模块,1) pcre/8.33 2) acml/5.3.1/gfortran64,加载,我编译BLAS共享库使用

gfortran -shared -O2 *.f -o libblas.so -fPIC

和静态库使用

gfortran -O2 -c *.f -fPIC
ar cr libblas.a *.o

然后我将共享库libblas.so复制到〜/ src / octave-3.8.1。 lapack的目录中的make.inc文件的内容是:

LAPACKLIB    = liblapack.a
TMGLIB       = libtmglib.a
LAPACKELIB   = liblapacke.a

然后我输入make来编译LAPACK。编译后,我将输出liblapack.a复制到〜/ src / octave-3.8.1。

./configure命令行是:

./configure --prefix=$HOME/bin/octave --with-blas=./libblas.so --with-lapack=$HOME/src/octave-3.8.1/liblapack.a --disable-readline --enable-64

我可以通过./configure。然后我键入make以尝试构建八度音程3.8.1并且我得到了上述错误。

make.inc文件可以看出,我已经遵循编译器“recompile with -fPIC”的建议并相应地修改了make.inc。我还在-shared变量中添加了OPTS开关。另外,我尝试使用旧的LAPACK版本,但没有工作。我真的不知道为什么错误仍然存​​在。所以我想知道你是否可以告诉我如何编译LAPACK库,以便在安装octave 3.8.1时正确使用它。以下两点可能值得考虑。 (1)我应该将lapack编译为静态库还是共享库? (2)应该将-fPIC开关应用于lapack编译或octave的make吗?如果是后者,如何申请-fPIC呢?您不必限制上述两点,因为可能有其他原因导致错误。欢迎任何解决这个问题的建议。如果您需要任何其他信息,请告诉我。谢谢。

刚刚在我老板的野兽上编译了lapack共享库...这里的a link几乎做得对。我做了一些改变:

(1)将-fPIC添加到

OPTS & NOOPT in make.inc

(2)将make.inc中的名称更改为.so

BLASLIB = ../../libblas.so

LAPACKLIB = ../liblapack.so

(3)在./SRC中,从中更改Makefile

../$(LAPACKLIB): $(ALLOBJ)
    $(ARCH) $(ARCHFLAGS) $@ $(ALLOBJ)
    $(RANLIB) $@

../$(LAPACKLIB): $(ALLOBJ)
    $(LOADER) $(LOADOPTS) -shared -Wl,-soname,liblapack.so -o $@ $(ALLOBJ) ../libblas.so

Cuz lapack正在调用blas,如果你错过了最后一部分,你的liblapack.so将失败!你需要链接liblapack.so libblas.so(libatlas.so也行)。您可以使用“ldd liblapack.so”来检查其依赖性。如果你在那里看到libblas.so,那么你做得很对。

(4)在./BLAS/SRC中,从中更改Makefile

$(BLASLIB): $(ALLOBJ)
$(ARCH) $(ARCHFLAGS) $@ $(ALLOBJ)
$(RANLIB) $@

$(BLASLIB): $(ALLOBJ)
$(LOADER) $(LOADOPTS) -z muldefs -shared -Wl,-soname,libblas.so -o $@ $(ALLOBJ)

(5)我不需要libtmg.so所以我没有改变它...运行

make blaslib 

然后

make lapacklib

您将编译它们。我检查了liblapack.so,并在其上构建了一个numpy并加载了Python ctypes.cdll。所有工作对我来说都是解决特征值和特征向量...所以应该没问题......

(6)您可能需要将LD_LIBRARY_PATH设置为保存库文件的位置。 google it ...如果没有由admin设置,那么

export LD_LIBRARY_PATH=path-to-lib

如果已经设置,那么

export LD_LIBRARY_PATH=path-to-lib:$LD_LIBRARY_PATH

覆盖默认的库。

这样你就不会有ld链接错误。祝好运!!

在lapack-3.7.0中,SRC / Makefile中有冗余行。只需删除它们即可解决您的错误。

我建议使用OpenBLAS。

> git clone https://github.com/xianyi/OpenBLAS.git
> make
> make make --PREFIX=INSTALL_DIR install

将librabries从OpenBLAS移到/ usr / lib64

> cp /path/to/OpenBLAS/lib/* /usr/lib64/

然后转到八度安装路径并运行

> "your specific flags" ./configure "your specific arguments" --with-blas="-lopenblas"
