Please first make sure you have looked at:

• Documentation: https://github.com/mkleehammer/pyodbc/wiki
• Other issues

Environment

To diagnose, we usually need to know the following, including version numbers. On Windows, be
sure to specify 32-bit Python or 64-bit:

• Python: 2.7.6
• pyodbc: Latest version
• OS: ubuntu 14.04.5
• DB:

Your machine does not have the ODBC header files installed. You need to do

sudo apt-get install unixodbc-dev

and then try installing pyodbc again.

Hi,

I already have unixodbc-dev installed on my system. I followed this.

➜ sudo apt-get install unixodbc-dev

unixodbc-dev is already the newest version (2.3.1-4.1).

And I'm trying to install the latest pyodbc==4.0.22; still getting the same error. Any idea on this?

I'm using:

• Python 3.5.2
• Ms SQL Server 2017
• Ubuntu 16.04 LTS

Let me know if I need to install any other dependencies.

[kabirbaidhya]

Anyway, I figured out the issue. I had to install python3-dev on ubuntu (in addition to unixodbc-dev) and it did work.

In case anybody runs into this issue again. Please ensure you've installed these:

➜ sudo apt-get install python3-dev
➜ sudo apt-get install unixodbc-dev

FYI: Python 2.x users, will need python-dev instead.

[neostorm]

I'm see the same issue and both python3-dev and unixodbc-dev are installed.
I've looked elsewhere and installed every recommended package any other thoughts on how to fix this?

But after installing python3-dev and unixodbc-dev, it got resolved.

Can you make sure you have all these dev packages installed on your system? Not sure if this works, but these include pretty much all the dependencies usually required for python.

➜ sudo apt-get install build-essential libssl-dev libffi-dev python3-dev
➜ sudo apt-get install unixodbc-dev

[gordthompson]

@neostorm - How did you install Python 3.6 on that machine?

[carlosmarin]

RHEL / CentOS:

yum install unixODBC
yum install unixODBC-devel

[ikwijaya]

using alpine??

[ffedoroff]

for python3.7 run also:
sudo apt-get install python3.7-dev

[luissamano]

for python3.7 run also:
sudo apt-get install python3.7-dev

Thanks, It worked.

[dxkaufman]

I have the same issue in Visual Studio Code on Mac OSX while trying to deploy a timer trigger function to Azure Functions. The function works perfectly while executing within VSC, but the deployment fails with the same 'unable to execute gcc' error. I found another issue talking about that, where I've asked for help too, but if anyone watching this issue can help me, I'd be very grateful!

[v-chojas]

@dxkaufman what you're describing has nothing to do with pyODBC, and that error message is very generic, so it is no surprise you will find issues about it which are completely unrelated to your situation.

[dxkaufman]

@v-chojas For that matter, I seem to have read this post inattentively... I thought it mentioned the gcc error, but now I realize this one has more to do with the presence of code files... my mistake. Thanks for the quick reply.

[rskelley9]

Might just come down to the version of Python one is using. I was using python 3.6 on ubuntu 14.04, so

sudo apt-get install python3.6-dev
sudo apt-get install unixodbc-dev
python3.6 -m pip install pyodbc

Worked for me.

[sumitkarn]

worked for me on ubuntu 14.04. thanks

Perfectly solved my problem.

[karlkaebnick]

on ubuntu 18.04 and python3.7, python3.7 dev was required for me:

sudo apt-get install python3.7-dev

[rudder-sameer-keluskar]

On ubuntu 16.04 and using python3.6 I am still getting the error.
But while installing python3.6-dev using the following command
sudo apt-get install python3.6-dev
I am getting an error

E: Unable to locate package python3.6-dev
E: Couldn't find any package by glob 'python3.6-dev'
E: Couldn't find any package by regex 'python3.6-dev'

After doing research on it, I found that we could add python3.6-dev package using the following repo:
sudo add sudo add-apt-repository ppa:deadsnakes/ppa -y && sudo apt-get update

But does adding this repo trustworthy?

[gordthompson]

deadsnakes has been around for a long time and I've never seen anyone suggest that it is not trustworthy. However, the ultimate decision of whether or not to trust a third-party repo is up to you.

[epomatti]

This worked for me:

sudo apt-get install python3.8-dev

That looks like Linux, not Windows; and the solution is to install unixodbc-dev, which has the header files for unixODBC.

You have to update your python repository by installing yum install python3-devel

[hol-workshop]

bloody hell, this was required yum install python3-devel
after that pip install pyodbc
finally 4revalo

[akristic]

This helped me from doccuments site:
https://github.com/mkleehammer/pyodbc/wiki/Install
Ubuntu 18.04
On Ubuntu systems, all you need to do is run

sudo apt install python3-pip
sudo apt install unixodbc-dev
sudo apt install python3-dev
pip3 install --user pyodbc

I just didn't use --user because of ERROR: Can not perform a '--user' install. User site-packages are not visible in this virtualenv.

I solved it by using this command and then install pyodbc

! apt install unixodbc-dev -y

[iammathh]

Install pyodbc on Centos / RHEL

Why PyODBC is needed?

To connect to any Database via Python. (There are specific drivers available for each database, pyodbc serves as a common library)

These are must have libraries for any development work, so its better to have them installed as part of any CentOS / RHEL setup.

$ sudo yum install unixodbc-dev
$ sudo yum install unixODBC unixODBC-devel
$ sudo yum install epel-release$ sudo yum install gcc-c++

These are specific to Python ODBC.
Before using pip3, make sure you have pip installed.

$ pip3 --version
$ sudo yum install python3-devel
$ sudo pip3 install pyodbc

The installation can be tested as follows

$ python3

>>> import pyodbc

If no errors are thrown, then your installation is perfect.
