Problem building matcaffe with XCode 6

[dgolden1]

Using the dev branch, commit 6af4575, I get the following error when running make matcaffe:

Building with 'Xcode Clang++'.
ld: framework not found vecLib
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I have what I believe is the latest version of XCode 6 (Version 6.0.1 (6A317)) and command line tools (6.0.0.0.1.1410400753) installed:

$ pkgutil --pkg-info=com.apple.pkg.CLTools_Executables
package-id: com.apple.pkg.CLTools_Executables
version: 6.0.0.0.1.1410400753
volume: /
location: /
install-time: 1412278538
groups: com.apple.FindSystemFiles.pkg-group com.apple.DevToolsBoth.pkg-group com.apple.DevToolsNonRelocatableShared.pkg-group 

Here's my Makefile.config: https://gist.github.com/drdan14/cedd7c5eab6ba503c16b

I'm on a Macbook Air with no GPU and OS X 10.9.5.

Yes, same error here for make matcaffe with OS X 10.9.5

Perhaps the vecLib path has changed in the latest Xcode. Try to patch the
Makefile or as a workaround configure your installation for OpenBLAS
instead of ATLAS / Accelerate / vecLib.

That should have been try to patch your mexopts.sh build configuration, not
the Makefile. If the Makefile paths were wrong nothing would build at all.

You can get over the vecLib hump with the following change:

    # OS X packages atlas as the vecLib framework

•   BLAS_INCLUDE ?= /System/Library/Frameworks/vecLib.framework/Versions/Current/Headers/
  

•   # BLAS_INCLUDE ?= /System/Library/Frameworks/vecLib.framework/Versions/Current/Headers/
  

•   BLAS_INCLUDE ?= /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.9.sdk/System/Library/Frameworks/Accelerate.framework/Versions/Current/Frameworks/vecLib.framework/Headers/
  LIBRARIES += cblas
  

•   LDFLAGS += -framework vecLib
  

•   # LDFLAGS += -framework vecLib
  

•   LDFLAGS += -framework Accelerate
  

(saw this on caffe users google groups IIRC).

After this, I encountered a LD-related error that I resolved by pointing to the correct C++ run-time. (libstdc++)

This allowed me to build the mex binary but I haven't tested it out to ensure it works correctly at run-time.

Here's a Makefile patch against 5c4125d (master): https://gist.github.com/drdan14/19596fe46d4b92db2012

This solves the vecLib problem (and it was @vimalthilak's idea).

However, after applying that patch, I run into other errors that look like this:

Building with 'Xcode Clang++'.

Fix available in #1310

Credit @vimalthilak for coming up with it

[shelhamer]

This should be fixed with #1740. Please follow-up if not. Sorry for the turnaround time on 10.10!

Hi, I add this in my Makefile according to vimalthilak' suggestion, but it still comes the error "ld: framework not found vecLib". Could you help me of that?

[soulslicer]

I have the same error as well
