[SOLVED] crosscompiler says: "unsupported target, invoke compiler driver?"
att2:
Hello,
What I did so far:
* On a Win10 machine, I installed virtualbox 5.2.x (latest version as of today).
* Inside the Virtualbox, there is a OpenSuse Leap 42.3 Linux.
* I used fpcupdeluxe 1.6.0p to install Lazarus "fixes version" (1.8.3) and FPC "trunk" version.
* I pressed "install and update fpc/laz
* I re-started fpcupdeluxe, selected "cross compile: AARCH64 / Linux" and "install FPC".
* Everything worked fine.
Result so far: Lazarus IDE starts up nicely. When compiling to normal=same architecture (Intel x64) everything works and compiles as it should.
But when I try to switch to "cross-compile to aarch64" by using:
"Project -> Project options -> config and target -> aarch64 " ... then I use
"Tools -> Configure ' Build Lazarus' " -> (correct options, then) "Build"
I get the error:
Error: Unsupported target architecture -Paarch64, invoke the "fpc" compiler driver instead.
I don't know how to properly proceed and "invoke the fpc compiler driver" .
How to do this?
Have I missed any options?
Please, any advice is greatly appreciated. I need cross-compilation working.... ;)

Addition: When compiling, I also get the message:
unit1.pas(46,0) Error: Assembler arm-linux-as not found, switching to external assembling
Any advice?

I solved my problem!!!!!!
I made symbolic links so that my cross compilation directory looks like this:
armdevel@linux-4mcd:~/fpcupdeluxe/cross/bin/aarch64-linux> ls -al

So , for every "aarch64-something" file I made a symbolic link with a name of "arm-something" (same rest of file name).
Now it works!!!!!!!
Problem Solved!!!
Thaddy:
Two things:
1. there is no such thing as a freepascal compiler driver. It is a compiler, bar none.
2. that's an awful lot of symlinks and that should not be necessary. You need just one.
One symlink in /usr/bin or /usr/local/bin that points to /usr/lib/fpc/3.0.4/ppcarm or /usr/local/lib/fpc/3.0.4/ppcarm if your installation is correct.
But you are using fpcdeluxe - which does not use conventions - and that should just work unless you also have a previous installation from the distribution itself.

Thaddy: 1.)
--- Quote ---Error: Unsupported target architecture -Paarch64, invoke the "fpc" compiler driver instead.
--- End quote ---
1.) is the direct copy/paste from the Error message. Yes, it says "driver". Yes, it irritated me too. So there.
2.) What has ppcarm to do with a missing assembler/linker name of "arm-....something" ?
