Ndless makefile/make install error linux - linux

Question

I have read up here about how to install the Ndless SDK on Linux, and I have followed as much as I could, like installing packages via terminal with:
sudo apt-get install [package]
all goes well until I reach the root "make" command. I do as the directions say, in ~/Ndless, and run "make" in the terminal. I receive this error each time I try to do this:
make -C ndless-sdk
make[1]: Entering directory '/home/pi/Ndless/ndless-sdk'
make -C libsyscalls

Also, I created a .bash_profile in my home directory, and added this to it, as shown in the directions:
export PATH="/home/pi/Ndless/ndless-sdk/toolchain/install/bin:/home/pi/Ndless/ndless-sdk/bin:${PATH}"
When the directions displayed PATH environment variable as bold, I took to the web and found that .bashrc was the PATH, so I added the same above code to it.

Anywhere the string user appears in the below commands for changing directories, just replace that with your username in Linux.
Update apt-get
sudo apt-get update
If this fails make sure you temporarily disable your VPN connection; it did for me.
Install packages
sudo apt-get -y install git && sudo apt-get -y install gcc && sudo apt-get -y install binutils && sudo apt-get -y install libmpfr-dev && sudo apt-get -y install libmpc-dev && sudo apt-get -y install zlib1g-dev && sudo apt-get -y install libboost-program-options-dev && sudo apt-get -y install wget && sudo apt-get -y install texinfo && sudo apt-get -y install python2.7 && sudo apt-get -y install python2.7-dev && sudo apt-get -y install python3 && sudo apt-get -y install python3-dev && sudo apt-get -y install php && sudo apt-get -y install libboost-dev && sudo apt-get -y install build-essential && sudo apt-get -y install gcc-arm-none-eabi && sudo apt-get -y install python
Clone Ndless into home
git clone --recursive https://github.com/ndless-nspire/Ndless.git
Run build_toolchain
cd Ndless/ndless-sdk/toolchain && ./build_toolchain.sh
Ndless command path
export PATH="/home/user/Ndless/ndless-sdk/toolchain/install/bin:/home/user/Ndless/ndless-sdk/bin:${PATH}"
Ndless Makefile
cd /home/user/Ndless && make
All of this will take a long time (took 5 hours for me), depending on your hardware and maybe internet connection.
Notes
Lets try building this simple file:
// main.cpp
#include <libndls.h>
#include <SDL/SDL.h>
#include <SDL/SDL_config.h>
int main() {
SDL_Surface *screen;
nSDL_Font *font;
SDL_Init(SDL_INIT_VIDEO);
screen = SDL_SetVideoMode(320, 240, has_colors ? 16 : 8, SDL_SWSURFACE);
font = nSDL_LoadFont(NSDL_FONT_TINYTYPE, 29, 43, 61);
SDL_FillRect(screen, NULL, SDL_MapRGB(screen->format, 255, 0, 0));
nSDL_DrawString(screen, font, 10, 10, "Hello, world! \x1");
SDL_Flip(screen); // update screen
SDL_Delay(3000); // wait for 3 seconds
SDL_Quit(); // get out of SDL screen, returns to normal nspire
return 0;
}
To generate the makefile:
nspire-tools new main
Then run:
make
The output should look something like this:
user#DESKTOP-6IBLUJD:/mnt/d/NdlessSDK/workspace/cpp/test$ make
nspire-g++ -Wall -W -marm -Os -c main.cpp -o main.o
mkdir -p .
nspire-ld main.o -o main.cpp.elf
genzehn --input main.cpp.elf --output main.cpp.tns.zehn --name "main.cpp"
make-prg main.cpp.tns.zehn main.cpp.tns
rm main.cpp.tns.zehn
I did this in WSL, so I had to do cd cd /mnt to reach my main drives to compile.
You can also try running that in Firebird Emulator with Ndless installed!
If you skip ahead, and decide to run make without fully completing the ./build_toolchain command (probably resulting from an error), don't be surprised if the make command fails. The output for the failure will be something about a
undeclared PATH_MAX
But, if you install all the necessary packages, and fully build the commands with success, Ndless should compile and function without issue.
If you get a nspire-gcc: Command not found while building the SDK, make sure you set the PATH variable correctly. I did echo "$PWD" which shows my current directory, which I used for Ndless path.
