Raspbian gcc does not know '.intel_syntax'?

1

I tried to execute:

gcc -o main main.c squrt.S -lm -no-pie

This worked on a different computer, but this time it did not know a single instruction:

Is there some package I have to install?

What CPU do you have in your pi? – ctrl-alt-delor – 2019-07-21T23:28:13.120

@ctrl-alt-delor The OP never stated that they were using a Raspberry Pi to run Raspbian. https://www.raspberrypi.org/downloads/raspberry-pi-desktop/

@Aron Sorry. Lett me re-phrase: What CPU do you have in your device? – ctrl-alt-delor – 2019-07-22T13:11:41.757

The "assembly" language is architecture-dependent, since its very point is to directly write CPU instructions, and each CPU type has different ones. Your entire program is written in amd64 / Intel x86_64 assembly code, but Raspbian doesn't run on those – it runs on ARM devices, and so the standard gcc that comes it also expects ARM assembly.

(Take a look at lscpu and gcc -dumpmachine to find out what CPU type you have.)

If you want the program to run on ARM CPUs, you have to rewrite all of it. There's (probably) no gcc package that can compile x86 assembly to run on ARM, though there might be translators to help you with rewriting.

If you want the program to run on amd64/x86_64 CPUs, but only compile it on Raspbian, you have to install a cross-compiler. (It might be in gcc-x86-64-linux-gnu + binutils-x86-64-linux-gnu.)

4And this is why people write in C, which (very roughly) started as architecture-independent assembly. – Mast – 2019-07-22T07:44:09.163

Not strictly true. There is an official flavour of Raspbian which will compile and run that code with zero modification. https://www.raspberrypi.org/downloads/raspberry-pi-desktop/
