libjpeg-turbo dependency with MacPorts

[igorsyl]

The build instructions use brew for dependencies. I can't build using MacPorts dependencies however:

MBP:~/go-vncdriver% python build.py
Could not find libjpeg. HINT: try 'sudo apt-get install libjpeg-turbo8-dev' on Ubuntu or 'brew install libjpeg-turbo' on OSX

[tlbtlbtlb]

You can tell the build script where to find it by setting LIBJPG in the environment. Like,

LIBJPG=/opt/local/lib/libjpeg-turbo.dylib python build.py

I'm not sure where Macports puts the library, but

port contents libjpeg-turbo

should tell you.

[igorsyl]

Thanks, is there a similar variable for include path?

MBP:~/go-vncdriver% sudo LIBJPG=/opt/local/lib/libturbojpeg.dylib python build.py

```

[tlbtlbtlb]

In that case, run the export and build commands manually, adding in a -I /opt/local/include/ to the CGO_CFLAGS.

ie from the go-vncdriver directory,

cd ..
export GOPATH="$PWD/go-vncdriver/.build"
export GO15VENDOREXPERIMENT='1'
export CGO_CFLAGS='-I/opt/local/include -I/opt/local/Library/Frameworks/Python.framework/Versions/3.6/lib/python3.6/site-packages/numpy/core/include -I/opt/local/Library/Frameworks/Python.framework/Versions/3.6/include/python3.6m'
export CGO_LDFLAGS='/opt/local/lib/libturbojpeg.dylib -undefined dynamic_lookup'
go build -buildmode=c-shared -o go_vncdriver.so github.com/openai/go-vncdriver

Beware that Tensorflow doesn't yet support python 3.6, so it may be difficult to run agents in this configuration. Python 3.5 is better supported.

[dogayuksel]

Thank you @tlbtlbtlb for great insights. I have a similar problem, would appreciate if you could give me a direction to investigate further.

I also couldn't get go-vncdriver to build using libjpeg-turbo installed through macports.
I am trying it in a conda environment. I had to deactivate jpeg library as it conflicts with libjpeg-turbo.

go version go1.6 darwin/amd64

My environment variables look like this:

GOPATH=/Users/doga/working/go-vncdriver/.build
CGO_LDFLAGS=/opt/local/lib/libturbojpeg.dylib -undefined dynamic_lookup
CGO_CFLAGS=-I/opt/local/include -I/Users/doga/.conda/envs/universe-starter-kit/lib/python3.5/site-packages/numpy/core/include/ -I/Users/doga/.conda/envs/universe-starter-agent/include/python3.5m

My build command looks like this:

(universe-starter-agent) doga:go-vncdriver $ go build -v -buildmode=c-shared -o go_vncdriver.so github.com/openai/go-vncdriver

And I get the following error as a result:

The installation assumes brew. Your life will be better generally if you switch to it. Since your jpeg library is in a different place, set `export LIBJPG= /opt/local/lib/libturbojpeg.dylib` before running `python setup.py build`.

I got an error like:

github.com/openai/go-vncdriver

go-vncdriver/.build/src/github.com/openai/go-vncdriver/main.go:5:10: fatal error: 'Python.h' file not found
#include <Python.h>
^~~~~~~~~~
1 error generated.

if I modify the GOPATH to where the .build folder is, then run:
go build -buildmode=c-shared -o go_vncdriver.so github.com/openai/go-vncdriver

[barracuda156]

I'm not sure where Macports puts the library, but

Add this to depends_lib-append in portfile:

path:include/turbojpeg.h:libjpeg-turbo

And possibly something like:

configure.args      --with-jpeg-includedir=${prefix}/include \
                    --with-jpeg-libdir=${prefix}/lib
