Edit report at https://bugs.php.net/bug.php?id=71343&edit=1 ID: 71343 Updated by: cmb@php.net Reported by: yohgaki@php.net Summary: Build system tries to link with Xcode libs and link fails -Status: Open +Status: Feedback Type: Bug Package: Compile Failure Operating System: OSX PHP Version: Irrelevant -Assigned To: +Assigned To: cmb Block user comment: N Private report: N New Comment: Is this still an issue with any of the actively supported PHP versions[1]? [1] <https://www.php.net/supported-versions.php> Previous Comments: ------------------------------------------------------------------------ [2016-06-04 01:15:49] yohgaki@php.net I build PHP on OSX on occasions and I still have this issue. The cause is EXTRA_LDFALGS/EXTRA_LDFALGS_PROGRAM define -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib before libs specified by configure options. If you have the same issue, remove OSX/Xcode system lib from EXTRA_LDFALGS/EXTRA_LDFLAGS_PROGRAMS. ------------------------------------------------------------------------ [2016-01-12 01:11:05] yohgaki@php.net Description: ------------ Xcode libs should have lowest precedence, but build system tries to link with Xcode libs and link fails. It seems not only -L flag, but also -I flag (and others) have the same issue. All supported/dev branches have this problem. Test script: --------------- $ YACC=/usr/local/opt/bison27/bin/bison ./configure --with-iconv=/usr/local/opt/libiconv && make -j 4 You'll need brew's bison27 and libiconv. Expected result: ---------------- Link should succeed. Actual result: -------------- cc -I/usr/local/opt/libiconv/include -g -O2 -fvisibility=hidden -L/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib -L/usr/local/opt/libiconv/lib -Wl,-rpath,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/lib -Wl,-rpath,/usr/local/opt/libiconv/lib ext/date/php_date.o ext/date/lib/astro.o ext/date/lib/dow.o ext/date/lib/parse_date.o ext/date/lib/parse_tz.o ***SNIP*** main/fastcgi.o sapi/cgi/cgi_main.o -lresolv -liconv -liconv -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -lxml2 -lz -licucore -lm -o sapi/cgi/php-cgi Undefined symbols for architecture x86_64: "_libiconv", referenced from: _zif_iconv_substr in iconv.o _zif_iconv_mime_encode in iconv.o _php_iconv_string in iconv.o __php_iconv_strlen in iconv.o __php_iconv_strpos in iconv.o __php_iconv_appendl in iconv.o _php_iconv_stream_filter_append_bucket in iconv.o ... ***SNIP*** ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=71343&edit=1
