fails to build on debian jessie about bmdtools HOT 11 OPEN

which version of Libav are you using?

Please use release 9 and do test the audio branch.

when i try and build i get the following

is this because i'm using debian Jessie/Testing?

Honestly I've not a clue how to use/install dev libs like that but... its in experimental so I will reopen the bug when the package is in testing so I can test it without breaking my "work" machine
I also found a pre-compiled version of BMDTools so I will use them until I can "roll" my own and package it for debian

but thanks you for your quick reply

from bmdtools.

I've now made a virtual machine and installed what looks like libavformat9.6-2
and changed to the audio branch and I'm now getting a new error

What about error with usage of the libavformat9.6-2. First of all do check if avcodec_open2 symbol exists in the libavcodec.so library which installed in the system by the next command nm -D /usr/lib/x86_64-linux-gnu/libavcodec.so.54 | grep avcodec_open2. If it does then try to change pkg-config --libs libavformat libswscale to pkg-config --libs libavutil libavcodec libavformat libswscale in the Makefile. If it does not then you have to use another version of the libav.

okay I've got libavformat 9 built in a neighbouring dir
with ./configure --enable-nonfree & make
I don't want to do a sudo make install on the libs as that killed my Debian system
but I've not a clue how to get make in bmdtools dir to link to my local plain9

from bmdtools.

edit the makefile and/or define the pkg config environment variables.

Some time ago I had same problem (now fixed in the last commit). I was getting the next error
$ make
g++ -o bmdcapture bmdcapture.cpp ../../include/DeckLinkAPIDispatch.cpp pkg-config --cflags libavformat libswscale -D__STDC_CONSTANT_MACROS -Wno-multichar -I ../../include -fno-rtti -g pkg-config --libs libavformat libswscale -lm -ldl -lpthread

/usr/local/lib/libavcodec.so.55: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make: *** [bmdcapture] Error 1

But with the last version I'm getting another error
$ make
g++ -o bmdcapture bmdcapture.cpp ../../include/DeckLinkAPIDispatch.cpp pkg-config --cflags libavcodec libavformat libswscale -D__STDC_CONSTANT_MACROS -Wno-multichar -I ../../include -fno-rtti -g pkg-config --libs libavcodec libavformat libswscale -lm -ldl -lpthread

/usr/local/lib/libavutil.so.52: could not read symbols: Invalid operation
collect2: error: ld returned 1 exit status
make: *** [bmdcapture] Error 1

And this problem can can be fixed by adding libavutil to the PKG_DEPS list in the Makefile for me. Similar as I have told here

from bmdtools.

Speaking about that problem I can propose the next solution.
First of all build libav with some prefix and install it, on example
./configure --enable-nonfree --prefix=/home/user/bmdtools && make && make install
after that libav will be installed to the /home/user/bmdtools/{bin, lib, include, share} locations.
The next step is modify bmdtools Makefile. After

bindir ?= $(prefix)/bin

add the next lines

libdir ?= $(prefix)/lib
ifeq ($(origin PKG_CONFIG_LIBDIR), undefined)
export PKG_CONFIG_LIBDIR=$(libdir)/pkgconfig
endif

and make bmdtools with prefix you've defined for the libav, on example
make prefix=/home/user/bmdtools
but if you don't want install bmdtools to the location which starts with prefix, you can add path used as libav prefix in the bmdtools Makefile or execute as command before run make
export PKG_CONFIG_LIBDIR=/home/user/bmdtools/lib/pkgconfig

UPD: Seems that case was already discussed there #14 and proposed to use export PKG_CONFIG_PATH=/home/user/bmdtools/lib/pkgconfig instead of export PKG_CONFIG_LIBDIR=/home/user/bmdtools/lib/pkgconfig

from bmdtools.

Thanks untergrundbahn, I solve problem changing Makefile file and building libav with prefix.
Also, there is no prefix option in make, so in Makefile should be full path to libdir.

BTW. I'm on CentOS

from bmdtools.

You're right, it's my mistake, because make prefix=/home/user/bmdtools should be used instead of make --prefix=/home/user/bmdtools for make bmdtools. Also in such way you can specify bindir and libdir in command line.
