macOS Error symbol(s) not found for architecture x86_64

[Amott]

Hi everybody,

I am working on a project that consist in compiling a Windows application on Mac. The application is written in C++ with Qt. It is composed with libraries and the main project :
http://hpics.li/d8bb2ec
The project uses an external library, ODA, to manage .dwg and .dgn files.
The problem is when I compile the first library (MdCore), I get an error : symbol(s) not found for architecture x86_64.
At first I added -stdlib=libstdc++ to qmake argument but Qt generated me 0 byte files, so it was not the solution.
I have tried different version of the ODA libary : 32bit, 64bit for OSX 10.7 and 10.11. (My Mac is on OSX 10.11)
I made the command "file" on my libraries and here the output :

<ervery ODA lib> :
<lib>.a: current ar archive random library

<other lib on /usr/lib>.dylib :
Mach-0 universal binary with 2 architectures
(for architecture x68_64): Mach-0 64-bit dynamically linked shared library x86_64
(for architecture i386): Mach-0 dynamically linked shared library i386

I have tried to compile on 32 and 64bit but it does not change anything. I am on this problem for two weeks I don't know what I can do

I have made a topic on the Qt forum maybe you can find more information :
https://forum.qt.io/topic/69171/compile-generate-0-byte-files-on-os-x/11
https://forum.qt.io/topic/69171/compile-generate-0-byte-files-on-os-x/11
If someone have a clue or a solution I will be interested

Thanks !

I don't know anything about qmake but maybe you should just post what your compiler commands are to compile and maybe someone will be able to see what is wrong.

hi cqexbesd, thanks for your answer, here is the beginning of the build output :

17:34:10: Begin : "/Users/developpement/Qt/5.7/clang_64/bin/qmake" /Users/developpement/Desktop/Mediacad2/MdCore/MdCore.pro -r -spec macx-clang CONFIG+=debug CONFIG+=x86_64 CONFIG+=qml_debug

17:34:10: The process "/Users/developpement/Qt/5.7/clang_64/bin/qmake" has finished normally

17:34:10: Begin : "/usr/bin/make"

...

 

[cqexbesd]

What I meant was the qmake is just a tool for calling the compiler. Can you find the line where qmake calls the compiler?Presumably it's not calling it correctly or things would be working. Its at least somewhere to start.

I think it's here :

in my compilation output I have those lines several time, but only the last line changes (the name of the file changes)

Edit : here are the same lines but with spaces between them

There should also be a linking line - e.g. a line where clang++ is called without the -c argument. It might be useful if you can paste a link to the entire output in fact.

 

[Amott]

I don't think it's possible to change arguments of the compiler. I may do it with the prompt.
Here is the full output (it's very very long ! 100.000 lines) : http://textup.fr/171939hC


Edit : I compiled with the prompt so I have more lines on the output, and the last lines are interesting :

I think 100K output for a build from anything but the most complicated system is probably a sign that things have gone wrong somewhere - but that is a more general comment about the state of the industry.

Back to your specific problem. I don't see the linking errors you posted in the "full output" however this looks just to be a regular linker errors. As on other platforms, you can use nm (or Google) to find where those symbols are defined and it appears to be in /System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation for me (but I have a very old mac so it may not be true for you).

You wouldn't link against that library directly. Try adding

-framework CoreFoundation

to your linker flags.

Yes you are right !! Thank you so much I can compile now ! I was facing this problem for 3 weeks ! Thanks a lot !

hi guys ... i have ran into a very similar problem...but i am using the terminal to compile...can someone please help on how i can do the same solution in case of terminal?

i have a ./configure file ready and it runs smoothly but i get ffi... related "symbols not found ..." and somthing to do with the linker when i run make
