veejay-server installation failed

[billusbillus]

Hi ! I'm trying to use free software to vj and heard about veejay. Was just trying to install everything and got an error :

effects/isolate.c: In function ‘isolate_apply’:
effects/isolate.c:99:21: error: invalid controlling predicate
for (pos = len; pos != 0; pos--) {

So the whole installation failed :

make[2]: Leaving directory '/home/hbildstein/veejay/veejay/veejay-current/veejay-server/libvje'
Makefile:587: recipe for target 'all-recursive' failed
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory '/home/hbildstein/veejay/veejay/veejay-current/veejay-server'
Makefile:496: recipe for target 'all' failed
make: *** [all] Error 2

Any hint ? Thanks for your time and your work !

Hi! Not sure, the compiler complaint is unexpected , pos != 0 is a valid controlling predicate . Maybe there is some issue , or maybe your build environment is incorrectly setup ? It could even be a gcc compiler bug but those are pretty rare. As an easy workaround, you could first try to delete the offending section. Just delete lines 65-115 so the apply method is basically empty like this: void isolate_apply( void *ptr, VJFrame *frame, int *args ) { } If that helps your build, I will check for the obvious and fix it, but if you have similar problems appearing further down the build process, some info on your system and setup would be helpful, Cheers,

Hi ! Thanks for the quick response !

Indeed, I'm getting some other errors now :

avhelper.c:166:3: error: unknown type name ‘AVCodecHWConfig’; did you mean ‘AVCodecContext’?
AVCodecHWConfig *hw_config = avcodec_get_hw_config(codec_context->codec,i);

OR

avhelper.c:172:16: error: request for member ‘methods’ in something not a structure or union
if( hw_config->methods & AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX ) {
^~
avhelper.c:172:28: error: ‘AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX’ undeclared (first use in this function)
if( hw_config->methods & AV_CODEC_HW_CONFIG_METHOD_HW_DEVICE_CTX ) {
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I'm on Ubuntu 18 and using gcc (Ubuntu 7.5.0-3ubuntu1~18.04) 7.5.0. I should have set up the compilation environment correctly, following your instructions. Do you need other kind of information ?

Thanks again !
