pandas build on Cygwin

Question

I tried building pandas on Cygwin and run into an error building pandas.msgpack._packer:

building 'pandas.msgpack._packer' extension

The error is:

gcc: error: spawn: No such file or directory

And here's the build command:

gcc -Wno-unused-result -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -ggdb -O2 -pipe -Wimplicit-function-declaration -fdebug-prefix-map=/usr/src/ports/python3/python3-3.4.3-1.x86_64/build=/usr/src/debug/python3-3.4.3-1 -fdebug-prefix-map=/usr/src/ports/python3/python3-3.4.3-1.x86_64/src/Python-3.4.3=/usr/src/debug/python3-3.4.3-1 -D__LITTLE_ENDIAN__=1 -Ipandas/src/msgpack -Ipandas/src/klib -Ipandas/src -I/tmp/pip-build-mdmyz2dz/pandas/.eggs/numpy-1.10.2-py3.4-cygwin-2.3.1-x86_64.egg/numpy/core/include -I/usr/include/python3.4m -c pandas/msgpack/_packer.cpp -o build/temp.cygwin-2.3.1-x86_64-3.4/pandas/msgpack/_packer.o

I'm guessing that gcc isn't finding pandas/src/msgpack and its subdirectories because the prior builds use all the other links except for these.

I guess, my question is, has anyone tried to install pandas on Cygwin's python? If not, any clues on what's going on here?

Answer 1

Install the following packages in cygwin :

python2-numpy
python2-six
python2-wheel
python2-setuptools
python2-pip
python2-cython
gcc-core
gcc-fortran
gcc-g++
make
wget

And then in Cygwin Terminal, build and install

pip2 install pytz python-dateutil
pip2 install pandas

Answer 2

I successfully built pandas 0.18.1, I had to install gcc-g++.

If you're using baboon: pact install gcc-g++

Answer 3

this below is taken from another website, https://wiki.usask.ca/display/MESH/Running+Python+from+the+Cygwin+Terminal.

I report the steps below but all credit goes to the original writer.

Configuring Cygwin

Download and run the Cygwin installer: setup-x86.exe for 32-bit or setup-x86_64.exe for 64-bit (source: http://cygwin.com/install.html).

Search for and mark the following packages for installation:

• \All\Devel\make
• \All\Devel\gcc-core
• \All\Devel\gcc-fortran
• \All\Devel\gcc-g++
• \All\Python\python
• \All\Web\wget

Installing Python

Run "Cygwin Terminal" (mintty.exe) as an Administrator. Install Python using the following command:

wget https://bootstrap.pypa.io/ez_setup.py -O - | python

Install additional packages, as required:

easy_install --upgrade numpy
easy_install "python-dateutil==1.5"
easy_install --upgrade pytz
easy_install --upgrade pandas

Answer 4

For Python3.7 + on Cygwin do the following.

These instructions assume that python3 Cygwin package is not installed.

Install latest versions of following Packages using the Cygwin installer:

python37
python37-pip
python37-setuptools
python37-devel

Open the Cygwin terminal and run the following steps there.

Create symlink for /usr/bin/python3:

% ln -s /usr/bin/python3.7 /usr/bin/python3

Upgrade pip:

% python3 -m pip install --upgrade pip

Upgrade other packages:

% python3 -m pip list --outdated

... for each package that is outdated run:

% python3 -m pip install --upgrade <package>

Install pandas and dependencies (note: this takes quite a while):

% python3 -m pip install cython wheel pandas
