Hi,
The ImageMagick has stayed in V6 for too long and I tried to compile its V7 myself to see what the problem might be, and indeed I found a big problem
-- I got "Illegal instruction" when I tried to install the built package elsewhere.
At first it is almost like *"the built packages cannot be used in other machines, but only to the built machine itself"*, and it took me quite a
while to get to the bottom of it.
In summary,
- I tried to build with two cloud providers, and none of the built
packages can be used in my VPS.
- I then build in my VPS and the built packages can be used in my VPS
(ubuntu:22.04).
- however, it cannot be used in my Debian.
I now believe the "Illegal instruction" is because of not the distro but
the CPU instruction set the compiler decided to use, based on the CPU of
the machine.
It turns out that my Debian has the oldest CPU and least CPU flags, and
the package built there can be used anywhere else.
So here comes my question,
With current cloud-compiling approaches, how should we make sure that
the built package works for the older x86_64 CPUs possible, and especially about this Q16 compilation for ImageMagick?
PS, the compilation is done via
https://github.com/SoftCreatR/imei/.
thanks
