GCC version check does not work for GCC version 10.2 #67

Open goekce opened 3 years ago

goekce commented 3 years ago

I'm trying to build Vitis_Libraries/vision/L2/examples/resize. Following line does not work on newer GCC versions like 10.2.0:

https://github.com/Xilinx/Vitis_Libraries/blob/eff2d5dd627c8d6c7ef566567a96f263d2f801cc/vision/L2/examples/resize/utils.mk#L77

For example:

$ g++ -dumpversion 
10.2.0
$ expr 10 \>= 5
1
$ expr 10.2.0 \>= 5
0

On my computer, make TARGET=hw DEVICE=xc7z020-1clg400 outputs:

...
utils.mk:79: *** [ERROR]: g++ version older. Please use 5.0 or above.  Stop.

Workaround is to use the GCC shipped with the Vivado installation.

Hi, Thanks for reporting the issue!

We found the string produced by -dumpversion option may contain minor release and bug fix number or not depending on build-time configuration of GCC. We will implement a universal compiler version test in makefile.

All the best, Vitis Libraries
