compiler-errors - 修复孤立的 libhdf5.so 和 libhdf5_hl.so 库导致 Caffe 编译错误

Question

在我的/usr/lib/x86_64-linux-gnu 目录中有两个红色的库，

 libhdf5.so and libhdf5_hl.so

我的理解是这些是孤立的符号链接(symbolic link)。我删除了它们，但现在需要制作新的。
我确实找到了这些文件

/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5_hl.so

/usr/lib/x86_64-linux-gnu/hdf5/serial/libhdf5.so

所以我做了新的符号链接(symbolic link)，现在它们是蓝绿色的。

但是我在编译 CAFFE 时遇到这些错误

src/caffe/net.cpp:774:7: error: there are no arguments to ‘H5Fis_hdf5’ that depend on a template parameter, so a declaration of ‘H5Fis_hdf5’ must be available [-fpermissive]
   if (H5Fis_hdf5(trained_filename.c_str())) {
       ^~~~~~~~~~

Makefile:611: recipe for target '.build_release/src/caffe/net.o' failed
make: *** [.build_release/src/caffe/net.o] Error 1
make: *** Waiting for unfinished jobs....

那么我是否符号链接(symbolic link)了错误的文件？

不，它与库无关，因为您还没有进入链接阶段。您的错误是由于编译失败。见 this issue ，也许会有所帮助。
