All changes done before have to be applied 15 | to the newly generated code again. 16 | Adding code snippets to the XML source itself on the other hand may be a 17 | bit more complicated but this way your custom code will always be in the 18 | generated code no matter how often you rerun CodeGen_PECL. 19 | 20 | 21 | BUILDING ON UNIX etc. 22 | ===================== 23 | 24 | To compile your new extension, you will have to execute the following steps: 25 | 26 | 1. $ ./phpize 27 | 2. $ ./configure [--with-libsixel=...] 28 | 3. $ make 29 | 4. $ make test 30 | 5. $ [sudo] make install 31 | 32 | 33 | 34 | BUILDING ON WINDOWS 35 | =================== 36 | 37 | The extension provides the VisualStudio V6 project file 38 | 39 | sixel.dsp 40 | To compile the extension you open this file using VisualStudio, 41 | select the apropriate configuration for your installation 42 | (either "Release_TS" or "Debug_TS") and create "php_sixel.dll" 43 | 44 | After successfull compilation you have to copy the newly 45 | created "sixel.dll" to the PHP 46 | extension directory (default: C:\PHP\extensions). 47 | 48 | 49 | TESTING 50 | ======= 51 | 52 | You can now load the extension using a php.ini directive 53 | 54 | extension="sixel.[so|dll]" 55 | 56 | or load it at runtime using the dl() function 57 | 58 | dl("sixel.[so|dll]"); 59 | 60 | The extension should now be available, you can test this 61 | using the extension_loaded() function: 62 | 63 | if (extension_loaded("sixel")) 64 | echo "sixel loaded :)"; 65 | else 66 | echo "something is wrong :("; 67 | 68 | The extension will also add its own block to the output 69 | of phpinfo(); 70 | 71 | -------------------------------------------------------------------------------- /php/config.m4: -------------------------------------------------------------------------------- 1 | dnl 2 | dnl $ Id: $ 3 | dnl 4 | 5 | PHP_ARG_ENABLE(sixel, whether to enable sixel functions, 6 | [ --enable-sixel Enable sixel support]) 7 | 8 | if test "$PHP_SIXEL" != "no"; then 9 | 10 | PHP_ARG_WITH(libsixel, whether libsixel is available,[ --with-libsixel[=DIR] With libsixel support]) 11 | 12 | 13 | 14 | if test -z "$PKG_CONFIG" 15 | then 16 | AC_PATH_PROG(PKG_CONFIG, pkg-config, no) 17 | fi 18 | if test "$PKG_CONFIG" = "no" 19 | then 20 | AC_MSG_ERROR([required utility 'pkg-config' not found]) 21 | fi 22 | 23 | if !
