caffe make all error, /usr/bin/ld: cannot find -lboost_python3

[Sam813]

Dear All,

During the compilation of caffe from source i got this error:

AR -o .build_release/lib/libcaffe.a
LD -o .build_release/lib/libcaffe.so.1.0.0
/usr/bin/ld: cannot find -lboost_python3
collect2: error: ld returned 1 exit status
Makefile:572: recipe for target '.build_release/lib/libcaffe.so.1.0.0' failed
make: * [.build_release/lib/libcaffe.so.1.0.0] Error 1

Any one can help how to solve it?

MacOS?

You need to create symbolic links to redirect "libboost_python3.so" to "libboost_python-py35.so", in /usr/lib/x86_64-linux-gnu.
Please refer to this article for more details:

I followed the steps mentioned in that article and seems that issue is solved but it hit to another error
it seems never ending..
Can I have the sample of your makefile.config so i follow the way you set the paths. i guess there should be a problem in that part. it doesn't make sense to have this much errors.

What kind of errors are you encountering?
Have you set INCLUDE_DIRS and LIBRARY_DIRS correctly?
In fact, I followed the steps form this link:
https://chunml.github.io/ChunML.github.io/project/Installing-Caffe-CPU-Only/
This article reveals several common obstacles during caffe build, and provides solutions, thanks to @ChunML.
The Makefile.config may vary, according different personalized settings, anyway, I post my settings here, hope it help. And good luck with you.

thanks for the make file and the link. my make.config is almost same except im trying to compile it on anaconda and python3.
The recent issue is:
libpng16.so.16, needed by /home/Sam/anaconda3/lib/libopencv_imgcodecs.so, not found (try using -rpath or -rpath-link)
seems some of the opencv libraries are missing

This is not an issue with Caffe itself but an installation problem. When compiling from source, please make sure you've got all dependencies installed.

i just can not find files whose name contains "python3.so" or "python-py35.so". I use

find / -name "*_python*.so"

and got

/usr/lib64/libboost_python-mt.so
/usr/lib64/libboost_python.so

None of them seem to be the right one. But I have python3.5.0 in my ubuntu 16.04 well.
