linux - Ndless makefile/make 安装错误linux

Question

我已阅读here关于如何在 Linux 上安装 Ndless SDK，我已经尽可能地遵循了，比如通过终端安装软件包:

sudo apt-get install [package]

一切顺利，直到我到达根“make”命令。我按照说明在 ~/Ndless 中进行操作，然后在终端中运行“make”。每次我尝试执行此操作时都会收到此错误:

make -C ndless-sdk
make[1]: Entering directory '/home/pi/Ndless/ndless-sdk'
make -C libsyscalls
make[2]: Entering directory '/home/pi/Ndless/ndless-sdk/libsyscalls'

此外，我在我的主目录中创建了一个 .bash_profile，并将其添加到其中，如说明所示:

export PATH="/home/pi/Ndless/ndless-sdk/toolchain/install/bin:/home/pi/Ndless/ndless-sdk/bin:${PATH}"

当指令将PATH环境变量显示为粗体时，我上网发现.bashrc是PATH，所以我将上面相同的代码添加到其中。

以下用于更改目录的命令中出现字符串 user 的任何地方，只需将其替换为您在 Linux 中的用户名即可。

更新apt-get

sudo apt-get update

如果失败，请确保您暂时禁用您的 VPN 连接；它对我有用。

安装包

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

将 Ndless 克隆到家里

git clone --recursive https://github.com/ndless-nspire/Ndless.git

运行构建工具链

cd Ndless/ndless-sdk/toolchain && ./build_toolchain.sh

无限命令路径

export PATH="/home/user/Ndless/ndless-sdk/toolchain/install/bin:/home/user/Ndless/ndless-sdk/bin:${PATH}"

无尽的生成文件

cd /home/user/Ndless && make

所有这些都将花费很长时间(我花了 5 个小时)，具体取决于您的硬件和可能的互联网连接。

注意事项

让我们尝试构建这个简单的文件:

// 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;
}

生成 makefile:

nspire-tools new main

然后运行:

make

输出应该是这样的:

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

我在 WSL 中执行此操作，因此我必须执行 cd cd/mnt 以访问我的主驱动器进行编译。

您也可以尝试在安装了 Ndless 的 Firebird 模拟器中运行它!

如果您向前跳过，并决定在没有完全完成 ./build_toolchain 命令的情况下运行 make(可能是由于错误)，那么如果 make 命令失败，请不要感到惊讶。失败的输出将是关于 a

undeclared PATH_MAX

但是，如果您安装了所有必要的包，并成功地完全构建了命令，Ndless 应该可以正常编译和运行。

如果在构建 SDK 时遇到 nspire-gcc: Command not found，请确保正确设置 PATH 变量。我做了 echo "$PWD"，它显示了我当前的目录，我将其用于 Ndless 路径。
