Quoting Mark Beerling <beerling@online.de>:

Hallo All,

I recently got ROS 5.28 running on the RPi4 and found that GNUPLOT didn't run on the new hardware (Illegal Instruction). So I decided to recompile with the latest compiler. The compilation failed because dependency LibPNG12-0 didn't compile. After failing to get GNUPLOT to compile with LibPNG16-16  I took a look at LibPNG12-0.

In the file "setvars" from LibPNG12-0 I added at line 1:

AB_URL=https://downloads.sourceforge.net/project/libpng/libpng12/older-releases/1.2.54/libpng-1.2.54.tar.bz2

This was enough to compile the library and then GNUPLOT which now works on the RPi4 hardware.

Perhaps someone can update the "setvars" file for LibPNG12-0.

Regards

Mark Beerling
