Setting Up Ndless C Compiler
« on: August 14, 2011, 12:17:29 pm »
I posted this in the "Tutorial - Setting up C Development Environment for the TI-Nspire" section, but the topic hasn't been active for several months so I started a new one.

Anyways, here's my problem: I've added ...blah/ndless2/sdk/bin to my PATH variable (in Ubuntu) but when after typing in "make" in the hello sample folder, I get this error: "make: execvp: nspire-gcc: Permission denied." If I type in "sudo make", I get "make: nspire-gcc: Command not found." What's wrong?

Though it probably is outdated at this point, that tutorial was meant for setup in Windows.  I think some steps must be performed differently when setting up on Linux, but since I don't use Linux, I can't be of any help. :(

Sorry. :(

I've received some help from Lionel Debroux back in the main "Setting up the Development Environment" topic, although I'm still having some problems (and he hasn't responded yet  :o) Hopefully I can still get this thing going in Linux. I do also have Windows 7 installed, and I'll install YAGARTO as a last resort. Meanwhile, if you're interested, I'm making a bignum program (currently very slow but operational in Lua) that I'm porting over to C as soon as this is done: http://ourl.ca/12521

Please take the time to update the tutorial on Hackspire with any additional setup required for your Linux installation: http://hackspire.unsads.com/wiki/index.php/C_and_assembly_development_introduction

I haven't gotten the toolchain to actually work yet... it still doesn't compile samples. I'm waiting on Lionel Debroux (or anyone with knowledge) to help me through this...

What error(s) do you get when you try to compile the samples?

The terminal gives me "make: nspire-gcc: Command not found."
The line after, it gives error 127 with "command not found."

for that, you need to add [ndless directory]/sdk/bin to your path

Yeah, I did :( I also installed the package gcc-4.5-arm-linux-gnueabi, but Lionel told me it was better to use the script he posted for non-Ubuntu versions of Linux, found here: http://hackspire.unsads.com/wiki/index.php/C_and_assembly_development_introduction I ran the script and got an error while installing gcc.

Sorry for the double post, but I found something REALLY weird. I type in "nspire-gcc" into the console, and it gives me "/home/anonymous/ndless2/sdk/bin/nspire-gcc: 26: : Permission denied." It knows where nspire-gcc is!!! But then, I type "sudo nspire-gcc," and then it can't find the command!

My guess is that the PATH variable doesn't include /sdk/bin folder for the root user, but for the normal user PATH does include the bin folder. Does anyone have any ideas?

EDIT: I also tried copying and pasting the contents of my sdk/bin folder into /user/bin, since it's in the PATH variable no matter what, but now I get a permission error even with sudo...

Try changing the permissions of the bin directory, so that anyone can execute.

How do I change the permissions of a folder? (chmod on a folder?)

Try "sudo chmod 777" in that directory.
Or, you can run a file browser as root, and in the properties of that folder, change the permissions there. You may also have to do this for the files in that folder, I'm not sure if they inherit permissions from their parent or not.

It should not be necessary to use sudo or run anything as root in order to change the permissions on a directory that you created.

Edit: On Linux, read permission on a directory means being able to list the files in it, while execute permission means being able to access the files in it (provided you also have access to the individual files). These are probably already both set. It's execute permission on the nspire-gcc file that might be missing.

I still can't get it to work, even after changing permissions. :( I guess installing MSYS and YAGARTO are my only options...
EDIT: Could the Nspire-gcc errors be due to the ARM toolchain not being set up correctly? I installed an arm-linux-gnueabi instead of the recommended arm-none-eabi.
