编译 Caffe 时出错:ld:无法映射文件,errno=22
Error in compiling Caffe: ld: can't map file, errno=22
我正在尝试编译Caffe,并收到以下错误,我无法调试:
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)
我已经通过brew install openblas
下载了OpenBLAS,并收到了以下可能重要的输出:
==> 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
我将必要的路径添加到我的Makefile中。配置文件,在下面:

粗糙但工作方法:
在Makefile中更改以下行(不是配置)
LDFLAGS += $(foreach librarydir,$(LIBRARY_DIRS),-L$(librarydir)) $(PKG_CONFIG) $(foreach library,$(LIBRARIES),-l$(library))
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
