fix for dc1394_vloopback example inline funcs
I don't know why nobody else has this problem, but GCC apparently requires the 'static' keyword in addition to 'inline' when it's used in the same source file (ie, not a header).
*** Bug 385611 has been marked as a duplicate of this bug. *** For me it works now, if I omit the CFLAGS="-O0" out and ONLY "-O2" in. |
