Question: I have to integrate third party system through `BizTalk 2013`. The third party providing below two option for integration:

1. Flat files [(File Adapter)](https://msdn.microsoft.com/en-us/library/ee253326(v=bts.10).aspx)
2. Web Service API [(WCF-BasicHttp Adapter)](https://msdn.microsoft.com/en-us/library/bb246098.aspx)

What is the best way to integrate and what are the pros and cons of these? I am a beginner and want an expert opinion.

Answer: 
Here's a solution for this problem in Ubuntu 16.04

```
sudo add-apt-repository ppa:ubuntu-toolchain-r/test
sudo apt-get update
sudo apt-get install gcc-4.9
sudo apt-get upgrade libstdc++6

```

You can check if you get GLIBCXX desired version like this:

```
strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBCXX

```
I also ran into this while installing h3.
The answer by oklas helped me, but expanding on that answer.
The gcc version with `conda install -c anaconda gcc` is 4.8.5. It is **not compatible** with the `libstdc++.so.6.0.22`. So I **uninstalled it and installed a specific verision of gcc** (ver 6) and it solved my problem.
