This error indicates that the system cannot recognize the gcc command, which is usually due to the GCC compiler not being installed or not being added to the system PATH environment variable. Here are the solutions:
### 1. Install MinGW-w64 (GCC environment for Windows)
“`bash
# 1. Download the MinGW-w64 installer
# Visit https://winlibs.com/ to download the latest version of MinGW-w64
# Or use the official installer: https://sourceforge.net/projects/mingw-w64/
# 2. After installation, add the MinGW-w64 bin directory to the system PATH
# Typically it is C:\mingw64\bin or a similar path
# 3. Verify the installation
gcc –version
“`
“`
### 2. Alternatively, use the Developer Command Prompt for Visual Studio
If you have Visual Studio installed, you can use its built-in compiler:
“`bash
# 1. Open “x64 Native Tools Command Prompt for VS 2022”
# 2. Change to the project directory
cd c:\Users\cwm1688\zzzzz
# 3. Use cl.exe to compile
cl main.c data_manager.c dialog.c /link jansson.lib comctl32.lib /SUBSYSTEM:WINDOWS
“`
“`
### 3. Install the jansson library
You also need to ensure that the jansson library is correctly installed:
“`bash
# 1. Download jansson for Windows
# Download the precompiled version from https://github.com/akheron/jansson/releases
# 2. Place jansson.h and jansson.lib in the MinGW or VS include/lib directory
# 3. Place jansson.dll in the project directory or a directory included in the system PATH
“`
“`
### 4. Alternative (if you do not want to install MinGW)
You can use TDM-GCC, which is a simpler Windows GCC distribution:
“`bash
# Download link: https://jmeubank.github.io/tdm-gcc/
# After installation, you also need to add the bin directory to the PATH
“`
“`
After installing one of the methods, you should be able to successfully run the gcc command. After installation, it is recommended to run a simple test program to verify that the compilation environment is working correctly.
