我想在Debian上安裝CBLAS，在Python3.4上安裝Numpy和Scipy。想要安裝CBLAS，但得到錯誤「未定義的引用`pthread_atfork'」
我指的是網站： http://osdf.github.io/blog/numpyscipy-with-openblas-for-ubuntu-1204.html http://www.kde.cs.tut.ac.jp/~atsushi/?p=493
首先，我已經安裝了OpenBLAS。
$git clone git://github.com/xianyi/OpenBLAS
$sudo vim /etc/ld.so.conf.d/libc.conf
$sudo ldconfig
$cd ~/Downloads/openBLAS
我只更改了「Makefile.rule」中的以下兩行。其他仍然是違約。
NO_CBLAS = 1
NO_LAPACK = 1
返回到shell並make。
$ make
$ sudo make PREFIX=/usr/local install
$ sudo ldconfig
它成功了。
接下來，我試圖安裝CBLAS。
$wget http://www.netlib.org/blas/blast-forum/cblas.tgz
$tar xzf cblas.tgz
$cd ~/Downloads/CBLAS
而且我編輯了Makefile.in，如下所示。
#
# Makefile.LINUX
#
#
# If you compile, change the name to Makefile.in.
#
#
#-----------------------------------------------------------------------------
# Shell
#-----------------------------------------------------------------------------
SHELL = /bin/sh
#-----------------------------------------------------------------------------
# Platform
#-----------------------------------------------------------------------------
PLAT = LINUX
#-----------------------------------------------------------------------------
# Libraries and includes
#-----------------------------------------------------------------------------
BLLIB = /usr/local/lib/libopenblas.a
CBLIB = ../lib/libcblas.a
#-----------------------------------------------------------------------------
# Compilers
#-----------------------------------------------------------------------------
CC = gcc
FC = gfortran
LOADER = $(FC) -lpthread
#-----------------------------------------------------------------------------
# Flags for Compilers
#-----------------------------------------------------------------------------
CFLAGS = -O3 -march=native -m64 -fomit-frame-pointer -fPIC -DADD_
FFLAGS = -O3 -march=native -m64 -fomit-frame-pointer -fPIC
#-----------------------------------------------------------------------------
# Archive programs and flags
#-----------------------------------------------------------------------------
ARCH = ar
ARCHFLAGS = cr
RANLIB = ranlib
返回到shell並make。
$make
但是，會顯示此類錯誤消息。
ranlib ../lib/libcblas.a

我無法解決錯誤。我想讓你告訴我是否有解決方案。 我會非常感謝大家的建議。對不起，我英文很差。
