awk: symbol lookup error: awk: undefined symbol: mpfr_z_sub
Symptoms
Running TCL script of a Vivado 2016.4 project on Ubuntu 16.04 (.6) LTS emits this error. It looks like a bug in Vivado 2016.4 which is triggered while running on Ubuntu. There are possible solutions. My solution doesn’t look like the best one but it works.
Solution
Open bin/loader file located at Vivado installation directory, for example
... Vivado/2016.4/bin/loader. Find the following code around line 420.
OS=$(awk '/DISTRIB_ID=/' /etc/*-release | sed 's/DISTRIB_ID=//' | tr '[:upper:]' '[:lower:]')
Comment the line and add a one line command as follows.
#OS=$(awk '/DISTRIB_ID=/' /etc/*-release | sed 's/DISTRIB_ID=//' | tr '[:upper:]' '[:lower:]')
OS="ubuntu"
By doing this we are assigning variable OS directly. If you execute the
problematic line at shell, you will get ubuntu as expected. However AFAIK
awk command executed at bin/loader script is different than the command
executed at command line due to include order of the script.
This solution works but the solution given there may be a better solution.
