erreur dans la compilation Caffe: ld: ne peut pas mapper fichier, errno = 22

Question

Je suis en train de compiler Caffe et je reçois l'erreur suivante que je ne peux pas debug:

ld: can't map file, errno=22 file '/usr/local/opt/openblas/lib' for architecture x86_64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

J'ai téléchargé OpenBLAS via brew install openblas et reçu la sortie potentiellement importantes suivantes:

==> Caveats 
This formula is keg-only, which means it was not symlinked into /usr/local. 

macOS already provides this software and installing another version in 
parallel can cause all kinds of trouble. 

Generally there are no consequences of this for you. If you build your 
own software and it requires this formula, you'll need to add to your 
build variables: 

    LDFLAGS: -L/usr/local/opt/openblas/lib 
    CPPFLAGS: -I/usr/local/opt/openblas/include 

J'ai ajouté les chemins nécessaires à mon dossier Makefile.config, ce qui est inférieur:

méthode grossière, mais de travail:

changement la ligne suivante dans le Makefile (non config)

LDFLAGS += $(foreach librarydir,$(LIBRARY_DIRS),-L$(librarydir)) $(PKG_CONFIG) \ $(foreach library,$(LIBRARIES),-l$(library)) 

avec

LDFLAGS += $(foreach librarydir,$(LIBRARY_DIRS),-L$(librarydir)) $(PKG_CONFIG) \ $(foreach library,$(LIBRARIES),-l$(library)) \ -I/usr/local/opt/openblas/include \ -L/usr/local/opt/openblas/lib
