Hi All

I can't compile ffmpeg on a raspberry pi 4.

When I ./configure I use --enable-libzmq

This is system information:

uname -a

Linux rasberry 5.10.63-v8+ #1488 SMP PREEMPT Thu Nov 18 16:16:16 GMT
2021 aarch64 GNU/Linux

The error I get when i do ./configure .... is:

ERROR: libzmq >= 4.2.1 not found using pkg-config

I believe I do have the correct version of libzmq. I do this to check:

pkg-config --modversion libzmq

4.3.5

What am I missing?

As I see it ./configure complains that pkg-config does not inform about
the availability of a required version of libzmq.

But when I check the version of libzmq using pkg-config I do see a
higher version than the required version.

Please help

Thomas S

For compiling you need the development package installed, something like
libzmq-dev

Thanks a lot

I had this as the first part of the call to ./configure and as I see it I use a customized PKG_CONFIG_PATH:

PATH="$HOME/bin:$PATH" PKG_CONFIG_PATH="$HOME/ffmpeg_build/lib/pkgconfig" ./configure \

When I removed references til PKG in my call to ./configure everything turned out fine.

Thanks a lot
