I've tried using different solutions suggested to this problem but none seem to be working for me
I am trying to install pycrypto using pip install on my mac which I recently upgraded to 10.11 along with the latest Xcode as few people had suggested.
But I am still getting clang: error: linker command failed with exit code 1 (use -v to see invocation) error: command 'clang' failed with exit status 1
Here is also the full error log am getting in the terminal any help greatly appreciated

I think this topic might help. That guy has the same issue: On Mac OS X, easy_install fabric and/or easy_install pycrypto fails due to linker error "illegal text-relocation"
You just need to install all necessary libraries. I would suggest to use home brew http://brew.sh/

Why do I always get this error when I try to install accumulation-tree? I need this for optbinning. A similar package would also be a solution.

This error might be due to not having Cython installed. Alternatively, you can clone the repository from GitHub, remove the dependency tdigest from the list of install_requires in setup.py, and install from the source using python setup.py install.
Try running (in a terminal window)
xcode-select –install
(and clicking through dialog)
If that doesn't work try:
sudo xcode-select --reset
Several links show this problem in other contexts (e.g.)
https://developer.apple.com/forums/thread/673827

I'm trying to install "supplychainpy" package for python but i get a gcc error. "error: command 'gcc' failed with exit status 1"
Yes, I have installed the xcode devtools xcode-select --install

Yes, my pip is up to date pip install --upgrade pip
Yes, I have gcc installed (with brew install gcc).
Yes i have anaconda package installed with all the dependancies.

I installed 'swig' separately, and it works fine:
brew install swig
What may be the problem? I hope no modification is needed for the setup.py of the original code. Is that because my Mac to new?
Thanks for help.
It doesn't look like this is a newness issue. I would restart your machine and try again. Also, I would try to use another import method.
Good Luck!
I have been trying to install openfst python library for the last week, however I am stuck. I have read all similar questions on stack overflow and other websites but none of the instructions work.
I have the latest Xcode installed, using
brew install openfst
I also installed openfst, however when I want to install the python library by writing:
pip install openfst
in the terminal, I get:

I would suggest compiling OpenFST from source with Python enabled. It's pretty easy:
wget http://www.openfst.org/twiki/pub/FST/FstDownload/openfst-1.7.2.tar.gz
tar zxvf openfst-1.7.2.tar.gz
cd openfst-1.7.2
./configure --enable-python
make
sudo make install
I'm trying to compile pymssql for python 2.5. I'm doing this because I think the version of pymssql I have is compiled for python 2.4. This is the error I get which makes me think that:
