I'm trying to build omnet++ on Mac OS X Lion.
configure works fine, however I got this error when creating tk shared library.
Creating shared library: /Applications/omnetpp-4.3/lib/cc_-arch_i386/libopptkenv.dylib

I modified configure.user to use 64 bit architecture.
CFLAGS_DEBUG='-g -Wall -arch x86_64'
CFLAGS_RELEASE='-O2 -DNDEBUG=1 -arch x86_64'
LDFLAGS="-arch x86_64"
However, it looks like that omnet++ just uses 32 bit architecture.
make MODE=release
***** Configuration: MODE=release, TOOLCHAIN_NAME=cc_-arch_i386, LIB_SUFFIX=.dylib ****
How can I build omnet++ as 64 bit architecture?
I needed to add more options.
./configure CFLAG_ARCH='-arch x86_64'
make TOOLCHAIN_NAME=cc_-arch_x86_64

I am making a project in Mac OSX and use the boost compiled libraries (serialisation amongst others). I installed all my dependencies as x86_64 libraries, but now want to make explicitly 32 bit ones (i386) and recompile my project for 32bit users.
I have recompiled by libraries with g++ -m32 where appropriate and then re made 32 bit boost libraries using
./bootstrap.sh link=static
./b2 cflags=-m32 cxxflags=-m32 address-model=32 threading=multi architecture=x86 instruction-set=i686
I then recompile my project by explicitly linking to the 32 bit libraries. So something like
g++ file.cpp /usr/local/lib/boost_i386/libboost_serialization.a -m32 -o executable
where the library is explicitly the 32 bit version verified by using otool as follows with (partial) output (all list cputype as i386)
otool -hv -arch all libboost_serialization.a
Archive : libboost_serialization.a
libboost_serialization.a(basic_archive.o):
Mach header
magic cputype cpusubtype caps filetype ncmds sizeofcmds flags
MH_MAGIC I386 ALL 0x00 OBJECT 3 1180 SUBSECTIONS_VIA_SYMBOLS
However, when I compile my project (despite most dependencies working fine), it trips up and that symbols are missing for this architecture
Explicitly:
Undefined symbols for architecture i386:
"boost::archive::detail::shared_ptr_helper::shared_ptr_helper()", referenced from:
boost::archive::binary_iarchive::binary_iarchive(std::basic_istream<char, std::char_traits<char> >&, unsigned int)in ccCH1ama.o

boost::archive::binary_iarchive::~binary_iarchive()in ccCH1ama.o
ld: symbol(s) not found for architecture i386
collect2: ld returned 1 exit status
I have explicitly built the 32bit libraries, checked they are in fact 32 bit, and explicitly linked to them, I don't know what else to do. Any ideas?
Turns out the header files were boost v1.55 but the i386 libraries used the most current version v1.57. This caused the error. Building the libraries with the older v1.55 to match the headers fixed the problem.
I am trying to compile dynamic lib in Mac OS X Mavericks, but when I try to link it, it says:
Undefined symbols for architecture i386:
"operator new(unsigned long, int, char const*, int)", referenced from:
...
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Compile flags I use:
Wall -Wextra -m32 -march=pentium4 -arch i386 -fvisibility=hidden
tried with
-stdlib=libc++ -lstdc++ -lc++
not helping.
gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 5.1 (clang-503.0.40) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.0.0
Thread model: posix
Please help!
EDIT:
Ok, lack of attention:
ld: symbol(s) not found for architecture i386
So, figured out that this is only happening when -g flag is present :)
For release build there is no error.
The question that arises is why there is no debug information symbols on MacOS X for libc++ (operator new). Any clues?
I'm trying to make dynamic lib from set of .o files, but when i do
gcc -dynamiclib -current_version 1.0 mymod.o -o mylib.dylib
or
ld *.o -o mylib.dylib
i get a lot of errors like:
"_objc_msgSend", referenced from:
-[NSObject(NSObject_SBJSON) JSONFragment] in NSObject+SBJSON.o
"operator new(unsigned long)", referenced from:
MStatistic::instance() in MStatistic.o
StatisticProfileLoggingObserver::instance() in StatisticObserver.o
ld: symbol(s) not found for architecture x86_64
Can you please help me, how to solve it and get my .dylib?
You can pass -undefined dynamic_lookup as an option to ld, or:
-Wl,-undefined -Wl,dynamic_lookup to gcc or clang (which passes it to the linker).
From this line:
ld: symbol(s) not found for architecture x86_64
it sounds like you are building some libraries that have make files that only build for 32-bit architectures.
You need to modify the makefiles for all the libraries / frameworks you're building to build both 32-bit and 64-bit; and in a practical sense, all shipping MacOS machines are 64-bit capable so it may just be safe to build only for 64-bit.
In your compile / linking lines, add something like this: "-arch x86_64" and that should compile things for the 64-bit side. To do both 32 & 64-bit, you'll basically need to duplicate the compile & link lines with their own "-arch i386" and "-arch x86_64" lines.
I am trying to implement openssl code I found into my project but I get these linker errors that aren't going away. I checked that the frameworks are properly linked and even included the library and header search paths manually using ../lib and ../include. Despite this the error goes away when I get rid of the Openssl function or any function calls such as EVP_OpenUpdate or EVP_OpenInit. This only if I create and then call the function from my ViewController.h file for some reason.
Here is the log of the error:

Thanks in advance.
I had to rebuild the entire project from scratch in order to get it to work. I don't know why I had to do such a thing though.
I'm working with FFMPEG on Mac OSX, my Mac version is 10.6.8 (i386).
When I try to compile my C++ code linking a dynamic library:
g++ sdk.cpp -rpath /usr/local/lib/libinsight.dylib -o sdk
I get the following error:
Undefined symbols for architecture x86_64:
"_main", referenced from:

"av_open_input_file(AVFormatContext**, char const*, AVInputFormat*, int, AVFormatParameters*)", referenced from:

(so forth fo every FFMPEG call)
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
Without linking dylib I have no problem. What's the matter?
P.S. ffmpeg version is Mach-O 64-bit executable x86_64
g++ sdk.cpp -rpath /usr/local/lib/libinsight.dylib -o sdk
Shouldn't you be linking to libffmpeg somewhere? Try adding -lffmpeg to your link command line.
