编译caffe时发生错误：找不到libpng和libgfortran，共享库

时间：2015-09-16 06:50:36

标签： ubuntu g++ shared-libraries ld caffe

我尝试使用Anaconda在ubuntu 14.04 LTS上编译caffe，仅限CPU模式和OpenBLAS。不幸的是，我得到了一个ld错误。

我按照说明操作，添加了Anaconda没有附带的依赖项，并相应地调整了Makefile.config，特别包括Anaconda路径。 当我make all时，我收到你在下面看到的错误（我还包括Makefile.config），即使找不到的两个文件位于anaconda / lib文件夹中，也位于各自的pkgs文件夹中作为共享库

非常感谢你的帮助！

好吧，看起来我能够自己解决这个问题。我不知道它是否是一个很好的解决方案，所以我感谢任何评论：在文件夹/etc/ld.so.conf.d中我创建了一个文件fooLibrary.conf。此文件仅包含Anaconda的lib文件夹的完整路径。在sudo ldconfig之后，ld能够找到相关的包。一旦我完成了，我再次删除了文件，但我怀疑问题是否得到了最终解决。因此，我会对评论或更好的解决方案感到高兴。
