Subject: libv4l2 link error
Date: Tue, 15 Dec 2009 14:28:33 +0100 [thread overview]
Message-ID: <20091215132832.282400@gmx.net> (raw)
Hello,
I've a usb webcam which I want to apply to my ARM platform.
The webcam just supports pjpg format therefore I want to use libv4l2.
When I try to link libv4l2 to my application I get this error:
arm-linux-uclibc-gcc -Wall -O2 -g -I../libv4l2/include -L../libv4l2/lib -o capture capture.c -lv4l2 -lv4lconvert
../libv4l2/lib/libv4lconvert.so: undefined reference to `shm_open'
collect2: ld returned 1 exit status
make: *** [test] Fehler 1
I know this looks like a mistake with my cross compiler rather than a libv4l2 mistake but on all other appl/libs my compiler works fine.
I compiled the lib simply with:
make CC=arm-linux-uclibc-gcc PREFIX=my/path/libv4l2/ install
Anything missing?
Maybe someone can give me a hint how to solve this.
THX
Niko
