#34247 [NEW]: configure claims g++ does not support shared libraries (when used as LD)

From: arattink at correct dot net Operating system: Linux 2.4.25 SMP PHP version: 5.1.0RC1 PHP Bug Type: *Configuration Issues Bug description: configure claims g++ does not support shared libraries (when used as LD) Description: ------------ The configure fails to discover that that g++ (ie LD=/usr/bin/g++) supports shared libraries. From the output: checking whether the gcc linker (/usr/bin/g++) supports shared libraries... no I can assure you that g++ (used as 'ld) does support shared libs. I need to use g++ specificly because ld does not link C++ libraries correctly and we use some C++ code in our own extensions. g++ --version ==> 2.95.3 For the record: *only* LD is set, not CC or CXX or any xxxFLAGS. Reproduce code: --------------- LD=/usr/bin/g++ ./configure --disable_all Expected result: ---------------- checking whether the gcc linker (/usr/bin/g++) supports shared libraries... yes Actual result: -------------- checking whether the gcc linker (/usr/bin/g++) supports shared libraries... no Unfortunately it is nigh impossible to figure out what configure does. I also tried gcc-3.4.3 which claimed g++ did and did not support it in the same run, but in the end refused to build the .so file anyway. I also tried 'LD="g++ -v"' and '--with-gnu-ld' but to no avail. All these tests on a freshly untarred tarball to be sure. Yours sincerely, Arnoud Rattink. -- Edit bug report at http://bugs.php.net/?id=34247&edit=1 -- Try a CVS snapshot (php4): http://bugs.php.net/fix.php?id=34247&r=trysnapshot4 Try a CVS snapshot (php5.0): http://bugs.php.net/fix.php?id=34247&r=trysnapshot50 Try a CVS snapshot (php5.1): http://bugs.php.net/fix.php?id=34247&r=trysnapshot51 Fixed in CVS: http://bugs.php.net/fix.php?id=34247&r=fixedcvs Fixed in release: http://bugs.php.net/fix.php?id=34247&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=34247&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=34247&r=needscript Try newer version: http://bugs.php.net/fix.php?id=34247&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=34247&r=support Expected behavior: http://bugs.php.net/fix.php?id=34247&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=34247&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=34247&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=34247&r=globals PHP 3 support discontinued: http://bugs.php.net/fix.php?id=34247&r=php3 Daylight Savings: http://bugs.php.net/fix.php?id=34247&r=dst IIS Stability: http://bugs.php.net/fix.php?id=34247&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=34247&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=34247&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=34247&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=34247&r=mysqlcfg
