Error compiling php5.5.18 on MacOSX 10.10 (yosemite)

Question

I'm trying to compile php (5.5.18, version doesn't matter that much imho) on yosemite but it fails during the link phase. It looks like some apache symbols are gone?

(The following worked perfectly on Mountain Lion, but fails on Yosemite.)

cc -bundle -bundle_loader /usr/sbin/httpd -L/usr/lib -laprutil-1 -lldap -llber -lexpat -liconv -lsqlite3 -lldap -llber -L/usr/lib -lapr-1 -lpthread -I/usr/include -g -O2 -fvisibility=hidden  -arch x86_64 -bind_at_load

ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libs/libphp5.bundle] Error 1

Any ideas? I checked /usr/lib/libapr-1.dylib (with nm -g) and the symbols are not present. Where should I normally find those symbols? Is this missing a lib? What's really weird is that my custom build script worked fine on 10.9 but fails on 10.10

Thanks for the help! Nicolas

I used MacPorts to install some libraries (like mcrypt), and then I compiled the 5.5.18 source code (with Xcode command line) using the following ./configure -command:

./configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --sysconfdir=/private/etc --enable-gd-native-ttf --with-icu-dir=/usr --with-ldap=/usr --with-ldap-sasl=/usr --with-libedit=/usr --enable-mbstring --enable-mbregex --with-mysql=mysqlnd --with-mysqli=mysqlnd --without-pear --with-pear=no --with-pdo-mysql=mysqlnd --with-mysql-sock=/tmp/mysql.sock --with-readline=/usr --enable-shmop --with-snmp=/usr --enable-soap --enable-sockets --enable-sysvmsg --enable-sysvsem --enable-sysvshm --with-tidy --enable-wddx --with-xmlrpc --with-iconv-dir=/usr --with-xsl=/usr --enable-zip --with-mcrypt=/opt/local/include --without-iconv --with-freetype-dir=/opt/local --with-apxs2=/usr/sbin/apxs --with-openssl=/usr --with-curl=/usr --with-zlib=/usr --with-bz2=/usr

Install Xcode 6.1 at first, then:

sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include /usr/include

Answer 3

Turned out that it was using the following include path:

/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/usr/include/apache2/

Instead of the normal one:

/usr/include/apache2/

Some more info:

$ xcodebuild -version -sdk macosx

MacOSX10.9.sdk - OS X 10.9 (macosx10.9)
SDKVersion: 10.9
Path: /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk

Strange, I hope it helps other people.

Best, Nicolas
