#28564 [NEW]: Compiling informix extension fails if compiling out of tree

From: roques at mti dot ag Operating system: Debian GNU/Linux Sarge PHP version: 4.3.7RC1 PHP Bug Type: Compile Failure Bug description: Compiling informix extension fails if compiling out of tree Description: ------------ 1) A harmless error in the Makefile, which only occurs on out of tree builds is not ignored and causes make to abort. 2) The resulting module is empty, because HAVE_IFX is not defined, because config.h is not included. Both of these problems can be fixed by applying the following patch: diff -wurd php-4.3.7RC1.orig/ext/informix/Makefile.frag php-4.3.7RC1/ext/informix/Makefile.frag --- php-4.3.7RC1.orig/ext/informix/Makefile.frag 2002-06-13 20:01:41.000000000 -0400 +++ php-4.3.7RC1/ext/informix/Makefile.frag 2004-05-28 19:17:05.000000000 -0400 @@ -1,7 +1,9 @@ +OVERALL_TARGET += $(srcdir)/ifx.c $(srcdir)/ifx.c: $(srcdir)/ifx.ec $(builddir)/libphpifx.a (if test -d $(INFORMIXDIR); then \ - THREADLIB=POSIX $(INFORMIXDIR)/bin/esql -e $(IFX_ESQL_FLAGS) $(srcdir)/ifx.ec; mv ifx.c $@; \ + THREADLIB=POSIX $(INFORMIXDIR)/bin/esql -e $(IFX_ESQL_FLAGS) $(srcdir)/ifx.ec; \ + mv ifx.c $@ || true; \ else \ touch $@; \ fi) diff -wurd php-4.3.7RC1.orig/ext/informix/ifx.ec php-4.3.7RC1/ext/informix/ifx.ec --- php-4.3.7RC1.orig/ext/informix/ifx.ec 2003-11-02 19:14:06.000000000 -0400 +++ php-4.3.7RC1/ext/informix/ifx.ec 2004-05-28 19:17:05.000000000 -0400 @@ -37,6 +37,10 @@ /* prevent mod_ssl.h's header file from being included. */ #define AP_HOOK_H +#ifdef HAVE_CONFIG_H +# include "config.h" +#endif + #include "php.h" #include "php_globals.h" #include "ext/standard/php_standard.h" Reproduce code: --------------- curry:/tmp% cp -a php-4.3.7RC1/ext/informix /tmp curry:/tmp% cd informix curry:/tmp/informix% phpize Configuring for: PHP Api Version: 20020918 Zend Module Api No: 20020429 Zend Extension Api No: 20021010 curry:/tmp/informix% ./configure [...] curry:/tmp/informix% make /bin/sh /tmp/informix/libtool --mode=link gcc /usr/local/informix/lib/esql/checkapi.o -o libphpifx.a mkdir .libs ar cru libphpifx.a ranlib libphpifx.a (if test -d /usr/local/informix; then \ THREADLIB=POSIX /usr/local/informix/bin/esql -e -EDHAVE_IFX_IUS /tmp/informix/ifx.ec; mv ifx.c /tmp/informix/ifx.c; \ else \ touch /tmp/informix/ifx.c; \ fi) mv: ifx.c' and /tmp/informix/ifx.c' are the same file make: *** [/tmp/informix/ifx.c] Error 1 This is the first problem. It can be fixed by replacing: mv ifx.c $@ with mv ifx.c $@ || true to make make ignore the error, or by explicitely telling make to ignore all errors in this recipe. When this problem has been fixed make generates a shared PHP-extension named informix.so. This extension is unusable, becuase it is empty. The reason for this is, that ifx.ec does not include config.h and thus HAVE_IFX in not defined and the contents of the module is ommitted. -- Edit bug report at http://bugs.php.net/?id=28564&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=28564&r=trysnapshot4 Try a CVS snapshot (php5): http://bugs.php.net/fix.php?id=28564&r=trysnapshot5 Fixed in CVS: http://bugs.php.net/fix.php?id=28564&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=28564&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=28564&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=28564&r=needscript Try newer version: http://bugs.php.net/fix.php?id=28564&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=28564&r=support Expected behavior: http://bugs.php.net/fix.php?id=28564&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=28564&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=28564&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=28564&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=28564&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=28564&r=dst IIS Stability: http://bugs.php.net/fix.php?id=28564&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=28564&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=28564&r=float
