I am trying to build eigen on my Mac Air with Lion. I downloaded eigen3 (from http://eigen.tuxfamily.org/index.php?title=Main_Page) and have successfully run make install. However, when I try to run make check, I get the following error.
[ 1%] Built target sparse_extra_2
Linking CXX executable openglsupport
ld: warning: ignoring file /System/Library/Frameworks//GLEW.framework/GLEW,
missing required architecture x86_64 in file
Undefined symbols for architecture x86_64:

test_openglsupport() in openglsupport.cpp.o
"_glewInit", referenced from:
test_openglsupport() in openglsupport.cpp.o
"_glBegin", referenced from:
test_openglsupport() in openglsupport.cpp.o
I feel that this issue has to do with glew. I am now trying to install different versions of glew, but that doesn't seem to do anything.
Any advice on how to resolve the error? What does undefined symbols for architecture x86_64 mean anyway?
This probably means your installation of GLEW is incomplete. You can properly disable testing of OpenGL with cmake . -DEIGEN_TEST_NO_OPENGL=ON. Finally, note that Eigen is a header only library, so there is nothing to compile to use it.

While trying to build the latest GnuPG (2.1.1 modern), my build fails when trying to link t-stringhelp. make outputs:
ld: warning: ignoring file libcommon.a, file was built for archive which is not the architecture being linked (x86_64): libcommon.a

I don't know how to fix this as libcommon is part of the source, so it should build fine. When building with CFLAGS="-m64" (-arch x86_64 does nothing), I get this:
ld: warning: ignoring file ../common/libgpgrl.a, file was built for archive which is not the architecture being linked (x86_64): ../common/libgpgrl.a

I've also rebuilt all the depandancies (as I built them on Mavericks), except pinentry, as it can't find libiconv which is also installed. My configure outputs that its target is Darwin (x86_64-apple-darwin14.0.0), so this should work. I have also got all the latest prerequisites, tried to install everything in its own directory (--prefix=/usr/local/gnupg-2.1.1), build all the dependancies and GnuPG as 32 bits (again, fails on same error), created a separate build folder and tried to build in there, but only one thing so far has solved the error: looking at how libgpgrl.a is being built - it's only component is common/gpgrlhelp.c - so I cd'ed into g10 and tried to build gpg2, replacing ../common/libgpgrl.a with ../common/gpgrlhelp.o, the lib common.a with all of its object files, for all the libraries that didn't work. Then some programs weren't linking to libksba libgcrypt and libassuan, so I changed the Makefiles, so that they could link. I can now compile all the code well, I installed everything, but I get a new error, when I try to run gpg2:
dyld: lazy symbol binding failed: Symbol not found: __gcry_mpi_init

I could compile GnuPG-2.0.22 on Mavericks, but no version of GnuPG builds on Yosemite.
Please help, I'm really confused.
I’ve been running GnuPG 2.1 on Yosemite 10.10.2 (the latest public beta of as of this writing) for about a week and it’s been fine.
You can follow these directions for using brew tap or you can use the raw URL: brew install https://github.com/mtigas/homebrew-gpg21/raw/master/Formula/gnupg2.rb.
Note this formula installs GnuPG 2.1; not GnuPG 2.1.1, the version originally asked about. I can confirm this bug where gpg2 --refresh-keys fails with some keyservers using 2.1 (apparently fixed in 2.1.1) but it’ll get you 90% there.
It shouldn’t be hard to update the formula to install 2.1.1.
Update
Someone submitted a pull request for GNuPG 2.1.1 support—I just tried it and it worked great. Short answer: brew install https://raw.githubusercontent.com/calebthompson/homebrew-gpg21/2.1.1/Formula/gnupg2.rb.
Personally, I would install homebrew, which is a one-liner pasted from their website (http://brew.sh) then do
brew install gnupg
If therw are any problems, run
brew doctor
and heed the good doctor's advice.
Turns out I had a ranlib in /usr/local/bin/ranlib. It was broken, I don't know how it got there (I did try to build gcc at some point, it doesn't support make uninstall, so that's probably why). I just ran:
sudo mv /usr/local/ranlib /usr/local/ranlib_old
Then I just rebuilt all the dependancies, and it worked!
I make a build for iPhone for the first time and got a problem.
I already checked a lot of posts and didnt find answer.
When i make a build on device a get:
Undefined symbols for architecture armv7:

On simulator ok.

Can somebody tell what it is? Please
Your unity version is not compatible, just download the latest version of unity which I believe is 4.3.1 and try recompiling. Here is the link if you need it. http://unity3d.com/unity/download/download-mac
The new version is compatible with armv7.
ok if anyone else is experiencing the same problem here's a way out:
those 3 methods mentioned are declared in the RegisterMonoModules.cpp in the Libraries folder, usually. so take that cpp file and add it to your target's Build Phases > Compile Sources
then if you have additional SDK's integrated that are not added to the 'Compile Sources' the new build will throw some other errors. just make sure to add the wrapper .mm files from the sdk's to your Compile Sources. Usually one .mm file per sdk. (e.g. for unity facebook sdk it's FbUnityInterface.mm file)
hope this helps
I'm trying to build the basemap toolkit, from source, for matplotlib to run on my MacBook Pro under OS X 10.8. The C and C++ compiler are those included with the latest Xcode package. The package includes the geos-3.3.3 package which needs to be built separately and installed before the main basemap python package is built. When I do this, using the supplied Makefile, I get the following error when the makefile attempts to build the libgeos.dylib library:
Undefined symbols for architecture x86_64:
"std::auto_ptr<geos::geom::Envelope>::auto_ptr(std::auto_ptr_ref<geos::geom::Envelope>)", referenced from:

virtual thunk to geos::geom::GeometryCollection::computeEnvelopeInternal() constin libgeom.a(GeometryCollection.o)
ld: symbol(s) not found for architecture x86_64
collect2: ld returned 1 exit status
On a Fedora 17 machine, with gcc 4.7, this library builds successfully so there is obviously something going on with the Mac compiler/linker. However, I have no idea how to decode this message. What, for instance, is a "virtual thunk"? Any insight on how I can compile and build this on the Mac?
I used a different compiler and the problem went away. Try:
make CXX=c++
Worked for me. OSX 10.8.3, XCode 4.6.1.
I get this error on my Mac OS Lion when I use gcc make:

Note: I installed Macports in my machine. This used to work before, is this a known issue with MacPorts?
you can use the built in libiconv by selecting your target, going to the Build Phases tab and adding it to the link libraries and frameworks build phase.
as a general rule if you are missing linker symbols you can look up the symbol in your project and see what header they are from, and you can then usually figure out the appropriate library or framework.
in this case it tells you what library it is expecting...
you will want to use the built in version for a dynamic library, because with default linker flags, if this built product were to get moved to another computer it would try to resolve the symbols at run time in that location, and crash.
I am using Xcode 3.0 to compile a test C program using CFITSIO library.
Following advice I have encountered from previous posts, I have built CFITSIO as a universal library, and added the fitsio.h and libcfitsio.a files to my project. I have verified I am using the correct build (x86_64). I have verified the libcfitsio.a file is under the Target > Link Binary with Libraries tab. I continue to receive the following error.
A previously created project using cfitsio works - I wasn't the one to link the library.
Also, I can link cfitsio successfully from terminal.
Any suggestions?

It seems as though the library is not fully universal. Try building your project for just one of the architectures at a time (i.e., just ppc, ppc64, i386, and x86-64 separately). When (if) one of them fails, you know which architecture your library is missing so you can recompile it with that. (Or, alternatively, if you don't intend to deploy on that architecture, you can just not compile for it. For instance, there's no real point in building PPC 64 unless you really will benefit from it, as the only machines that will run it are G5s, and they'll run plain old PPC 32-bit code just fine.)
Once I edited Xcode
'Project' > 'Edit Project Settings' > 'Architecture'
to not include PPC, which seemed to be there by default, the build succeeded. I am running OSX 10.5.8 on Intel Core 2 Duo.
Previously I had been using various builds of the cfitsio library itself, and not changing the default architecture on my Xcode project.
