Hi,
Please find below a patch to the qcam backend to fix undefined symbols
at runtime when dlopening the symbols on GNU/kFreeBSD (GNU libc with a
FreeBSD kernel).
This platform uses a GNU libc, so <sys/io.h> is available. However the
check in the source code is done on __linux__ and not on __GLIBC__.
I would even change the line to
#if defined(HAVE_SYS_IO_H) || defined(HAVE_ASM_IO_H) || defined(HAVE_SYS_HW_H)
but they may have systems where one of those is defined and the where
the associated functions inb and outb functions are not defined.
Thanks,
Aurelien
