gcc to build RISC OS

I’m supposed to do this:

ro-path is a script that redirects calls to host tools like gcc to ones that build for RISC OS. For instance:

$ /home/riscos/env/ro-path ./build-me.sh

but, I have an error executing this command:

kaizen@Rk:~$ /home/kaizen/gccsdk/env/ro-path ./build-me.sh

/home/kaizen/gccsdk/env/ro-path: line 27: ./build-me.sh: No such file or directory

can I please know what might be the mistake?

The terminal has to be open in the folder containing build-me.sh, which itself should be set to be executable.

djp@ubuntu1910:~/Work/gcc$ /home/djp/gccsdk/env/ro-path ./build-me.sh

Worked here. HTH.

Thank you for the reply, but I’m unable to find the folder containing build-me.sh, it still doesn’t work for me.

http://www.riscos.info/index.php/Cross-compiling_software_with_GCCSDK

The build-me.sh file has to be written and in the example above it would go in the same folder as the source.

My source hello.c is in ~/Work/gcc, with the terminal open in that folder this compiles it.

djp@ubuntu1910:~/Work/gcc$ /home/djp/gccsdk/env/ro-path gcc  -o hello hello.c

In the same folder create a file build-me.sh containing the command and set to be executable.

#!/bin/sh
gcc -o hello hello.c

This line then executes build-me.sh

djp@ubuntu1910:~/Work/gcc$ /home/djp/gccsdk/env/ro-path ./build-me.sh

Thank you for making me understand it clearly. Now after this where can I find the RISC OS executable files.

Do you mean this, home/djp/gccsdk/cross/arm-unknown-riscos/bin?

Ah no, I was asking about:

bash: ./hello: cannot execute binary file: Exec format error

how can I execute this in ubuntu?

how can I execute this in ubuntu?

It can’t be done. The compiled hello is a RISC OS executable, the file needs to be transferred to a RISC OS installation to run it. ro-path invokes cross compilation.

Thank you :)

the file needs to be transferred to a RISC OS installation to run it.

Which is when you need to look at "this linked site:http://www.marutan.net/rpcemu/index.php for an emulation of an old RISC OS based system.
