linux - 为 Intel Edison 交叉编译 portAudio

Question

我正在使用 Intel Site 中的交叉编译环境并使用它成功编译了其他几个库(libsndfile、alsa、fftw)，但是当我尝试编译 portaudio 时，它拒绝链接到正确的目录。这是我得到的错误:

if test -n " bindings/cpp" ; then for dir in " bindings/cpp"; do make -C $dir all; done ; fi

它似乎试图链接到我的计算机正常的 libstdc++，我不知道为什么。我已经尝试使用正确的目录输入 configure 各种 LDFLAG，并重新安装了工具链和我所有的 multilib，但没有成功。

我也遇到了这个问题，最简单的方法是在同一命令行上执行 sudo su 后再次获取环境文件，然后执行 make install。

以下是我为 intel edison 交叉编译 portaudio 所遵循的步骤:

1. 从这个link 下载交叉编译器edison-toolchain-20150120-linux64.tar.bz2 和脚本toolchain-20140724-linux64.sh。

2. 提取工具链，运行脚本(如果你愿意，可以将它放在你的主目录中的某个地方)并设置交叉编译环境

$ tar -xvf edison-toolchain-20150120-linux64.tar.bz2   
$ chmod +x toolchain-20140724-linux64.sh   
$ ./toolchain-20140724-linux64.sh  
$ source /opt/poky-edison/1.6/environment-setup-core2-32-poky-linux

1. 检查 shell 上的环境:

$ echo $CC  
$ i586-poky-linux-gcc -m32 -march=core2 -mtune=core2 -msse3 -mfpmath=sse -mstackrealign -fno-omit-frame-pointer --sysroot=/opt/poky-edison/1.6/sysroots/core2-32-poky-linux

配置、编译和安装portaudio:

$ ./configure
$ make
$ sudo su
# source /opt/poky-edison/1.6/environment-setup-core2-32-poky-linux
# make install
