2. Compiling from Source (Advanced)

If you need a specific version or want to control the compilation process, you can compile cURL from source:

wget https://curl.haxx.se/download/curl-VERSION.tar.gz
tar -xzf curl-VERSION.tar.gz
cd curl-VERSION

3. Updating with the curl Command

You can also update the cURL command directly using the curl command itself (for certain versions of cURL):

curl -L https://curl.haxx.se/ca/cacert.pem > cacert.pem
curl -L https://curl.haxx.se/download/curl-VERSION.tar.gz | tar -xz
cd curl-VERSION

2. Compiling from Source (Advanced)

You can also compile cURL from source on Windows. However, this process is more complex and requires additional tools:

  • Download the cURL source code from .
  • Install a C/C++ compiler like MinGW-w64.
  • Use the configure script to customize the build and run make to compile.

Verifying cURL Version

After updating, you can verify the new version using the following command:
