ubuntu - Caffe 链接错误，但 ldd 没有给出错误

Question

我正在使用 Ubuntu 16.04 在 Odroid 上构建 caffe，但出现链接错误：

[ 77%] Linking CXX executable compute_image_mean

这是的输出sudo ld lib/libcaffe.so.1.0.0：

sudo ld lib/libcaffe.so.1.0.0 
ld: warning: cannot find entry symbol _start; defaulting to 000101ec

lib/libcaffe.so.1.0.0: undefined reference to `leveldb::Status::ToString() const'

根据ldd lib/libcaffe.so.1.0.0，已找到所有必需的库。如何识别问题？
