I'm running Freeswitch 1.6 and Mac 10.10.5 My Freeswitch server will be in AWS and need to install Python ESL module in my local environment to start development using ESL. I havent been able to find ESL module. I got the whole source and tried to build only Python library.
I used this instructions.
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
When I go to libs/esl folder and type:
make pymod -v
I get:

When I run:
make pymod
I get this error:

ld: internal error: atom not found in symbolIndex(__ZN24SWIG_Python_Thread_Allow3endEv) for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [_ESL.so] Error 1
make: *** [pymod] Error 2
In my Makefile I have this:
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
The following solution solved it for me:
From https://freeswitch.org/jira/browse/ESL-92
There is a bug in the ld command that ships with Mac OS X post Mavericks, due to which the "-x" flag strips extra symbols. The bug is described here -x link flag causing link errors on Mac OSX 10.9 (bug?) (I've filed a ticket upstream https://llvm.org/bugs/show_bug.cgi?id=23337).
Workraround:
Remove the "-x" flag when linking _ESL.so
cd libs/esl
sed -i '' 's/\(SOLINK = .*\)-x/\1/p' Makefile
make pymod
