Arch Linux User Repository

I have modified the pkgbuild, get it and try again

I get the following linker error when running makepkg -si:

/usr/bin/ld: CMakeFiles/output_http.dir/output_http.c.o:(.bss+0xa60): multiple definition ofclient_infos'; CMakeFiles/output_http.dir/httpd.c.o:(.bss+0x0): first defined here collect2: error: ld returned 1 exit status`

Anyone know how to fix this? I'm using 5.8.3-2-MANJARO on x86_64. I saw a proposed fix here: https://github.com/jacksonliam/mjpg-streamer/issues/257#issuecomment-653551536 but my changes disappear when makepkg pulls from the repo again. Not sure what to do...

My patch to PKGBUILD to get it building without the HTTP management stuff, using the CMake-generated Makefile, and with @matterhorn's LDFLAGS fix:

I have the same problem as @celogeek, but it can be solved by removing the -DENABLE_HTTP_MANAGEMENT=ON line. Also, the build step doesn't build the package, it only runs the cmake stuff, and package doesn't use the setup provided by cmake because it doesn't cd …/_build.

Hi,

can you include this patch to your package:

This allow multiple connexions to the streaming and avoid 403 access denied: https://github.com/jacksonliam/mjpg-streamer/issues/162

I ran into the same problem as @bebR with mmal: mmal_component_create_core: could not find component 'vc.ril.camera'. The cause and a solution to the problem, as I understand it, is as follows:

The default /etc/makepkg.conf on both standard and Arch Linux ARM flavors sets

LDFLAGS="-Wl,-O1,--sort-common,--as-needed,-z,relro,-z,now"

where the -Wl,--as-needed option aggressively removes the link dependency on libmmal_vc_client.so in input_raspicam.so on RPi platforms despite it being set (as far as I can tell, correctly) as a hard dependency in the upstream CMakeLists.txt.

If the output of either readelf -d /usr/lib/mjpg-streamer/input_raspicam.so | grep "NEEDED.*libmmal_vc_client.so" or ldd /usr/lib/mjpg-streamer/input_raspicam.so | grep libmmal_vc_client.so is blank, the error will occur.

My fix is to override the default LDFLAGS to set --no-as-needed at link time to avoid the dependency on libmmal_vc_client.so from being stripped out:

though perhaps there's a way to override just the single option through CMake directives like CMAKE_SHARED_LINKER_FLAGS without resetting the entire LDFLAGS variable.

Final result is the raspicam input plug works correctly:

@jose1711, ok, no problem, i'll give another try to this git version. but the last tiem a tried, it wasn't working. thanks.

@bebR true, i requested the removal shortly after getting the following comment:

" mjpg-streamer don't have stable release, has already been deleted once for that and this is not even at the latest commit "

i was unable to find any reference of mjpg-streamer deletion in aur mailing list but anyway, it's gone. again.

@jose1711, thanks, but I can't find the package with the link you gave.

@bebR mjpeg-streamer is now back in aur (https://aur.archlinux.org/packages/mjpg-streamer/)
