This is a standalone PHP extension created using CodeGen_PECL 1.1.3 HACKING ======= There are two ways to modify an extension created using CodeGen_PECL: 1) you can modify the generated code as with any other PHP extension 2) you can add custom code to the CodeGen_PECL XML source and re-run pecl-gen The 2nd approach may look a bit complicated but you have be aware that any manual changes to the generated code will be lost if you ever change the XML specs and re-run PECL-Gen. All changes done before have to be applied to the newly generated code again. Adding code snippets to the XML source itself on the other hand may be a bit more complicated but this way your custom code will always be in the generated code no matter how often you rerun CodeGen_PECL. BUILDING ON UNIX etc. ===================== To compile your new extension, you will have to execute the following steps: 1. $ ./phpize 2. $ ./configure [--with-libsixel=...] 3. $ make 4. $ make test 5. $ [sudo] make install BUILDING ON WINDOWS =================== The extension provides the VisualStudio V6 project file sixel.dsp To compile the extension you open this file using VisualStudio, select the apropriate configuration for your installation (either "Release_TS" or "Debug_TS") and create "php_sixel.dll" After successfull compilation you have to copy the newly created "sixel.dll" to the PHP extension directory (default: C:\PHP\extensions). TESTING ======= You can now load the extension using a php.ini directive extension="sixel.[so|dll]" or load it at runtime using the dl() function dl("sixel.[so|dll]"); The extension should now be available, you can test this using the extension_loaded() function: if (extension_loaded("sixel")) echo "sixel loaded :)"; else echo "something is wrong :("; The extension will also add its own block to the output of phpinfo();
