python - ESL python 的 Freeswitch 1.6 安装

Question

我正在运行 Freeswitch 1.6 和 Mac 10.10.5我的 Freeswitch 服务器将位于 AWS 中，需要在我的本地环境中安装 Python ESL 模块才能使用 ESL 开始开发。我没能找到 ESL 模块。我得到了完整的源代码并尝试只构建 Python 库。

我用了this说明。

git clone -b v1.6 https://freeswitch.org/stash/scm/fs/freeswitch.git
cd /usr/src/freeswitch
./bootstrap.sh -j
./configure 
cd /usr/src/freeswitch/libs/esl

当我转到 libs/esl 文件夹并键入:

make pymod -v

我得到:

当我运行时:

make pymod

我收到这个错误:

clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [_ESL.so] Error 1
make: *** [pymod] Error 2

在我的 Makefile 中我有这个:

PYTHON = /Users/spicyramen/anaconda/bin/python
PYTHON_CFLAGS = -I/Users/spicyramen/anaconda/include/python2.7 -I/Users/spicyramen/anaconda/include/python2.7 -fno-strict-aliasing -I/Users/spicyramen/anaconda/include  -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes
PYTHON_LDFLAGS = -L/Users/spicyramen/anaconda/lib -ldl -framework CoreFoundation -lpython2.7
PYTHON_SITE_DIR = /Users/spicyramen/anaconda/lib/python2.7/site-packages

以下解决方案为我解决了这个问题:

来自 https://freeswitch.org/jira/browse/ESL-92

Mac OS X post Mavericks 附带的 ld 命令中存在错误，因此“-x”标志会去除额外的符号。该错误在此处描述 -x link flag causing link errors on Mac OSX 10.9 (bug?) (我已经在上游提交了一张票 https://llvm.org/bugs/show_bug.cgi?id=23337 )。

解决方法:

链接_ESL.so时去掉“-x”标志

cd libs/esl 
sed -i '' 's/\(SOLINK = .*\)-x/\1/p' Makefile 
make pymod
