treating errors as warnings, and there are warnings #3

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Not sure how to turn off treating warnings as errors, and if this is a good 
idea.

goinstall gmf.googlecode.com/hg/gmf

/bin/bash: === cd /home/richardworley/go/src/pkg/gmf.googlecode.com/hg/gmf; 
bash gomake -f- install
CGOPKGPATH=gmf.googlecode.com/hg cgo --

I commented out go/src/cmd/cgo/gcc.go "-Werror" to and ran ./all.bash
Then I ran gofix - hopefully bringing source go files up to date.

richardworley@ffmpegServer:~/go/src/pkg/gmf.googlecode.com/hg/gmf$ make
CGOPKGPATH= cgo -- -I/home/richardworley/ffmpeg/ffmpeg/include/ avformat.go

make: *** [_go_.6] Error 1

Running gofix - yields:
hg/gmf/Datasink.go: fixed oserrorstring
hg/gmf/Datasource.go: fixed oserrorstring
hg/gmf/Encoder.go: fixed math
hg/gmf/MediaLocator.go: fixed stringssplit
hg/gmf/Resampler.go: fixed oserrorstring

Now it tries to Make, but is running into lots of errors associated with 
libavcodec.
Here's a sample error:
ffmpeg/libavcodec/cook.c:174: undefined reference to `pow'

Replace avcodec_open with avcodec_open2. Now requires libavcodec 53.6.0 or 
newer.

Global avcodec_alloc_context
use avcodec_alloc_context3()
