Bug #17423 Updated: COMPILE_DL_MODULENAME different in configure and config.h.in

ID: 17423 Updated by: derick@php.net Reported By: list@firehawksystems.com Status: Open -Bug Type: Dynamic loading +Bug Type: *Compile Issues Operating System: FreeBSD 4.3, same on any unix PHP Version: 4.2.1 Previous Comments: ------------------------------------------------------------------------ [2002-05-25 01:38:16] list@firehawksystems.com I am changing the way I build my PHP extension and am running into some problems. I was originally would build it by copying the directory foo_bar into the ext directory and added --enable-foo_bar=shared to the configure line of PHP and build PHP. Everything worked great! Now I am looking to build it by: phpize ./configure --enable-foo_bar=shared make If I build PHP with the module and install it, include/php/main/php_config.h would have two lines in it: /* */ #define HAVE_FOO_BAR 1 /* Whether to build foo_bar as dynamic module */ #define COMPILE_DL_FOO_BAR 1 And now any clean rebuilds of the extension using the phpize way will work, becuase of the lines in php_config.h. Now if I do a clean build and install of PHP without the module, then try to build the module PHP via phpize, PHP can't load it. Running nm on it reveals that the get_module function is not in the .so file. I have traced the missing get_module function down to: #ifdef COMPILE_DL_FOO_BAR ZEND_GET_MODULE(foo_bar) #endif and COMPILE_DL_FOO_BAR is not defined at compile time. This is not defined because after running phpize config.h.in and configure are different: --- config.h.in #undef COMPILE_DL_FOO_BAR ---configure #define COMPILE_DL_FOOBAR 1 It seems that the configure script is getting the underscore removed from the module name. From what I can tell this is done in acinclude.m4 line 962: AC_DEFINE_UNQUOTED([COMPILE_DL_]translit($1,a-z-,A-Z_), 1, Whether to build $1 as dynamic module) I think this needs to be changed to: AC_DEFINE_UNQUOTED([COMPILE_DL_]translit($1,a-z_-,A-Z__), 1, Whether to build $1 as dynamic module) This will handle extensions with both dashes and underscores, I think. I also find the same line in the aclocal.m4, so it may need changed there to. Thanks, Brian BTW, no my extension is not named foo_bar, but it does have a underscore it. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=17423&edit=1
