Bug #78157 [NEW]: configure script does not find libargon2 library

From: e6990620 at gmail dot com Operating system: Alpine Linux PHP version: master-Git-2019-06-13 (Git) Package: Compile Failure Bug Type: Bug Bug description:configure script does not find libargon2 library Description: ------------ The following commit changed the --with-password-argon2 configuration flag to --with-argon2, and also how to detect the library in the system (i.e. by package name). https://github.com/php/php-src/commit/bdcef51bcb367323f2eea4808f34a1b3e58bd3d8 However, on Alpine Linux the libargon2-dev package is named argon2-dev, and the new configure script does not detect it even though usr/lib/libargon2.so and usr/lib/libargon2.a are present. Test script: --------------- ./configure --with-argon2 Expected result: ---------------- checking whether to build with Argon2 support... yes checking for libargon2... yes Actual result: -------------- checking whether to build with Argon2 support... yes checking for libargon2... no mconfigure: error: Package requirements (libargon2) were not met: Package 'libargon2', required by 'virtual:world', not found Consider adjusting the PKG_CONFIG_PATH environment variable if you installed software in a non-standard prefix. Alternatively, you may set the environment variables ARGON2_CFLAGS and ARGON2_LIBS to avoid the need to call pkg-config. See the pkg-config man page for more details. -- Edit bug report at https://bugs.php.net/bug.php?id=78157&edit=1 -- Try a snapshot (PHP 5.4): https://bugs.php.net/fix.php?id=78157&r=trysnapshot54 Try a snapshot (PHP 5.5): https://bugs.php.net/fix.php?id=78157&r=trysnapshot55 Try a snapshot (trunk): https://bugs.php.net/fix.php?id=78157&r=trysnapshottrunk Fixed in SVN: https://bugs.php.net/fix.php?id=78157&r=fixed Fixed in release: https://bugs.php.net/fix.php?id=78157&r=alreadyfixed Need backtrace: https://bugs.php.net/fix.php?id=78157&r=needtrace Need Reproduce Script: https://bugs.php.net/fix.php?id=78157&r=needscript Try newer version: https://bugs.php.net/fix.php?id=78157&r=oldversion Not developer issue: https://bugs.php.net/fix.php?id=78157&r=support Expected behavior: https://bugs.php.net/fix.php?id=78157&r=notwrong Not enough info: https://bugs.php.net/fix.php?id=78157&r=notenoughinfo Submitted twice: https://bugs.php.net/fix.php?id=78157&r=submittedtwice register_globals: https://bugs.php.net/fix.php?id=78157&r=globals PHP 4 support discontinued: https://bugs.php.net/fix.php?id=78157&r=php4 Daylight Savings: https://bugs.php.net/fix.php?id=78157&r=dst IIS Stability: https://bugs.php.net/fix.php?id=78157&r=isapi Install GNU Sed: https://bugs.php.net/fix.php?id=78157&r=gnused Floating point limitations: https://bugs.php.net/fix.php?id=78157&r=float No Zend Extensions: https://bugs.php.net/fix.php?id=78157&r=nozend MySQL Configuration Error: https://bugs.php.net/fix.php?id=78157&r=mysqlcfg
