Hello,
I’m trying to build the freeRTOS demo in Freedom Studio on macOS. I am getting build errors. The instructions I am following are listed here.
One of the errors I’m getting is this.
`/bin/sh: riscv64-unknown-elf-gcc.exe: command not found`
The `.exe` makes me think that this demo is configured for Windows instead of macOS?
Can anyone help me to get this to build? Thanks

Which freeRTOS demo are you referring to?

I wanted to use this one:

>
> Git clone of FreeRTOS svn repo. SVN found at: https://sourceforge.net/projects/freertos/ - FreeRTOS/FreeRTOS
But this one also does the same thing:

I got it working!
I had to go to the project properties and make a couple of changes.
`C/C++ Build / Environment`
I had to change PATH to be `/Applications/FreedomStudio.app/Contents/Eclipse/SiFive/sdk-utilities-0.0.0-2019.08.0:/Applications/FreedomStudio.app/Contents/Eclipse/SiFive/msys64-1.0.0-2019.05.2/usr/bin:/Applications/FreedomStudio.app/Contents/Eclipse/SiFive/riscv64-unknown-elf-gcc-8.3.0-2019.08.0/bin:/usr/local/bin:/usr/bin:/bin:/usr/sbin:/sbin`
Then under `C/C++ Build / Settings`
I had to change the `Cross GCC Compiler`, `Cross GCC Linker`, and `Cross GCC Assembler` to use `riscv64-unknown-elf-gcc` instead of `riscv64-unknown-elf-gcc.exe`

I also needed to modify the Hardware\_Qemu.launch file.
`PROGRAM_NAME` needed the backslash changed to the forward slash. So it is now:
```auto
```
`DEBUG_NAME` needed a `.exe` removed. It now reads:
```auto
```

Thanks for this. I had the same problem and this fixed it for me.
Took me a few minutes to find the project-specific settings, since it’s not in the normal preference settings.
For future travellers… You have to select your project name in the ‘project explorer’ pane, and then go to Project -\> Preferences
Is this an issue with the project files (e.g., specifying \*.exe) or with the global settings of FreedomStudio?

Pretty sure it’s a project setting. I have to change it every time I import it.

Change Debug-\>DebugConfigurations-\>GDB Hardware Debugging-\>Hardware Qemu-\>Main-\>C/C++ Application from “Debug\RTOSDemo.elf” to “Debug/RTOSDemo.elf”.
Then in the next tab (Hardware Qemu-\>Debugger) Change GDB Command to remove .exe:
iscv64-unknown-elf-gdb **.exe** -iex “set mem inaccessible-by-default off” -iex “set arch riscv:rv32” -iex “set riscv use\_compressed\_breakpoint off”

For Ubuntu, I did not need to delete the .exe under build, but needed to remove it from the gdb binary path under Debug Configurations (See Below). I also needed to update PATH as mentioned.
