build error

Hello, when I try to "make config=debug64"

I got this error

It looks like it is having trouble finding Bullet. Have you built bullet yet?

[lyokka]

Thanks for your reply, this happened during building those packages, I read your readme which I think that I don't need to install Bullet previously.

Please execute step 7 in the build instructions for the README.

Copy the prebuilt libraries from the external folder

cp external/caffe/build/lib/libcaffe.* lib/
cp external/Bullet/bin/.so lib/
cp external/jsoncpp/build/debug/src/lib_json/.so* lib/

I fixed the ordering in the build instructions.

I am trying to make on Ubuntu 16.04. I got same problem as the first asker after I followed the instructions of read.me. although I tried to install bullet of https://github.com/lunkhound/bullet3, the problem was not solved. Would you please telling the way to solve this problem.

Please copy the prebuild versions of Bullet form the given external library folder (https://github.com/xbpeng/DeepLoco/releases) to your lib directory.

Copy and Rename following three files in external/Bullet/bin folder:

libBulletDynamics_gmake_x64_release.so
libBulletCollision_gmake_x64_release.so
libLinearMath_gmake_x64_release.so

To:

libBulletDynamics_gmake_x64_debug.so
libBulletCollision_gmake_x64_debug.so
libLinearMath_gmake_x64_debug.so

Then follow step 5 to copy prebuild version from external library folders to your lib directory.

[Neo-X]

Yep, that would work fine. You should not need to debug bullet anyway.
