I’m trying to build a x86_64 application on MacOSX, using qmake/qt. I was able to compile in QT4, but not in QT5.
Anyway, after running qmake to generate my makefiles etc:
qmake -recursive -spec macx-clang app.pro CONFIG+='release static'
Then when I run make, eventually I end up here:
/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/clang++ -headerpad_max_install_names -arch x86_64 -Wl,-dead_strip -framework Cocoa -framework Carbon -Wl,-syslibroot,/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.8.sdk -mmacosx-version-min=10.6 -o [authors note: lots of .o files here] -L../lib -L../../debug -F/Users/seth/workspace/qt5.1.0//5.1.0/clang_64/lib -lprotobuf -framework Security -framework SecurityInterface -framework ApplicationServices -framework CoreFoundation -lxml2 -lbz2 -lxar -framework ScriptingBridge -L/Users/seth/workspace/qt5.1.0//5.1.0/clang_64/plugins/iconengines -lssl -lcrypto -lz -lFLAC -framework Carbon -framework QtWebKitWidgets -framework QtQuick -framework QtQml -framework QtNetwork -framework QtCore -framework QtGui -framework QtOpenGL -framework QtWidgets -framework QtPrintSupport -framework Cocoa -framework QtWebKit -framework QtSql -framework QtSensors -framework QtSvg -framework QtXml -framework OpenGL -framework AGL
and then error…
ld: '__ZN3Log16DebugE7QStringS3_' in debug/Log.o contains undefined reference for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)
I do not understand what ‘undefined reference for architecture x86_64’ means, and that’s certainly the heart of the problem. Upon reading some other threads, some suggest that the libraries I’m linking against aren’t x86_64, but after checking and rechecking, I can’t find any non-x86_64 libraries involved in the process.
All my .o files from the build are Mach-O 64-bit object x86_64 after checking with the file command.
And for all libraries that I’m trying to reference (like libcrypto, for instance):
Non-fat file: ../lib/libcrypto.a is architecture: x86_64
And of course all the mac framework libraries are both 32/64bit capable.
Does anyone have any suggestions on how I could debug this further?
