Dependency Table

When compiling PHP, each extension and library has dependencies, which may be required or optional. You can choose whether to include these optional dependencies.

For example, when compiling the gd extension under Linux, the zlib,libpng libraries and the zlib extension are forced to be compiled, while the libavif,libwebp,libjpeg,freetype libraries are optional libraries and will not be compiled by default unless specified by the --with-libs=avif,webp,jpeg,freetype option.

• For optional extensions (optional features of extensions), you need to specify them manually at compile time, for example, to enable igbinary support for Redis: bin/spc build redis,igbinary.
• For optional libraries, you need to compile and specify them through the --with-libs=XXX option.
• If you want to enable all optional extensions, you can use bin/spc build redis --with-suggested-exts.
• If you want to enable all optional libraries, you can use --with-suggested-libs.
