error: unknown type name ‘ptrdiff_t’ #2

Closed gwljf closed 7 years ago

gwljf commented 7 years ago

I want to build torch on TX1, and I tried your srcipt "CMakePreBuild.sh"

But when it runs 

$TORCH_PREFIX/bin/luarocks install $BUILD_ROOT/rocks/nn-scm-1.rockspec

, I receive a lot of errors of "error: unknown type name ‘ptrdiff_t’". Do you know how to fix this?

This is the log: 

cmake -E make_directory build && cd build && cmake .. -DCMAKE_BUILD_TYPE=Release -DCMAKE_PREFIX_PATH="/home/ubuntu/ws/torch/torch/bin/.." -DCMAKE_INSTALL_PREFIX="/home/ubuntu/ws/torch/torch/lib/luarocks/rocks/nn/scm-1" && make

Hi, I've updated the install script to work with the latest changes in Torch and avoided this error. Please try pulling or cloning the repo again - see commit 4daf842.

gwljf commented 7 years ago

@dusty-nv Thank you for the update. I have built it successfully. But I can't find th anywhere. Do you know the problem?

dusty-nv commented 7 years ago

The below installation of trepl rock is currently commented out in the CMake script:

$TORCH_PREFIX/bin/luarocks install trepl

However you can perform it manually by the following:

cd jetson-reinforcement/build/torch/bin luarocks install trepl

After running the above, th should then also appear in that dir.

dusty-nv commented 7 years ago

Do you have jetson-reinforcement/lua/NEON.c? If not, pull the latest master. CMakeLists.txt should then copy it into build dir.

@dusty-nv Thank you for the help. I will try later. Thank you.

deepcode123 commented 7 years ago

hi, @dusty-nv

I have the commend "qlua XX.lua", which is used for demo. But I can't find "qlua" , do I need to install something else?

Thanks!
