I have written c++ functions that use dlib face recognition. On Mac my code works fine but I cannot compile it to iOS.
First I generated Xcode projects with
cmake -G Xcode ..
When I try to build the library through Xcode project, the linker
Ld xcodebuild/Debug-iphoneos/dlibwrapper.bundle/dlibwrapper normal arm64

fails with:

How could I include arm64 versions of libcblas.dylib and liblapack.dylib to the build? Did I miss some build step?
Helllo, I have some code, that I'm trying to compile. The code runs well on Linux but I can't compile it on OSX.
In the makefile I use for Linux:
LD_FLAGS = -lcudart -L$(CUDA_HOME)/lib64
For Mac I try to use these flags:
LD_FLAGS = -lcudart -L$(CUDA_HOME)/lib
LD_FLAGS = -lm -F/Library/Frameworks -framework CUDA
CXXFLAGS = -O3 -g -m32 -I$(CUDA_HOME)/include
NVCC_FLAGS = -O3 -g -G -I$(CUDA_HOME)/include -arch=sm_11
This is the make output file:
mpic++ -c -o main.o main.cpp -O3 -m32 -I/Developer/NVIDIA/CUDA-5.0/include
/Developer/NVIDIA/CUDA-5.0/bin/nvcc -c -o kernel.o kernel.cu -O3 -I/Developer/NVIDIA/CUDA-5.0/include -arch=sm_11

This problem was caused by trying to mix 32 and 64 bit compilation between the CUDA and MPI toolchains. It was noted in comments that adding -m64 instead of -m32 for LD_FLAGS, CXXFLAGS, and NVCC_FLAGS produced a working 64 bit build.
I would like to know the configurations to run this Hello World program on Xcode. I have installed MacOSXFUSE.
With the command
gcc -Wall hello.c `pkg-config osxfuse --cflags --libs` -o hello
and then with
./hello outputdrive -f -s
I am able to successfully mount the drive outputdrive.
I have environmental variable declare set as -x PKG_CONFIG_PATH="/usr/local/lib/pkgconfig"
MacOSXFUSE is installed in /usr/local/include/osxfuse/
More information:
/usr/local/lib/pkgconfig/osxfuse.pc
data in this file is
prefix=/usr/local
exec_prefix=${prefix}
libdir=${exec_prefix}/lib
includedir=${prefix}/include
Name: fuse
Description: OSXFUSE
Version: 2.7.3
Libs: -L${libdir} -losxfuse -pthread -liconv
Cflags: -I${includedir}/osxfuse/fuse -D_FILE_OFFSET_BITS=64 -D_DARWIN_USE_64_BIT_INODE
A little progress,
I did this on terminal,
pkg-config osxfuse --cflags --libs
Pasted the below result in "other c flags" in xocde
-D_FILE_OFFSET_BITS=64 -D_DARWIN_USE_64_BIT_INODE -I/usr/local/include/osxfuse/fuse -L/usr/local/lib -losxfuse -pthread -liconv
Now I get the below error,
Undefined symbols for architecture i386:
"_fuse_main_real", referenced from:
_main in main.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Please let me know if more details is required.
You need to put the /usr/local/lib in the "Library search paths" and the library "libosxfuze" to the "Linked Frameworks and Libraries".
does it compile from command line?
g++ hello.c -I/usr/local/include/osxfuse/fuse -D_FILE_OFFSET_BITS=64 -v -L/usr/local/lib -losxfuse
Any suggestions for resolving the following error (unknown option passed to ld) will be highly appreciated. The "buildit" script is the one from http://libcxx.llvm.org/ with the line
export TRIPLE=-apple-
added to it.
Thanks in advance

I've been struggling for days with the same problem, but eventually got it compiled.
Before running the build script, try setting the following environment variables:
export TRIPLE=-apple-
export MACOSX_DEPLOYMENT_TARGET=10.6
I'm attempting to install version 1.10 of the cts package from CRAN on OS X, and I'm running into some linker problems. I need to install from source, because I'm making a few changes to the source (actually Zhu Wang, the cts author, made the changes & sent me the new tarball - but the same issue happens with the stock sources of cts on CRAN).
It seems to compile all the sources fine, but then fails with the following errors during linking:
> install.packages('~/Downloads/cts_1.0-11.tar.gz', .libPaths()[1], repos=NULL, type='source')
