[sbopkg-users] opencv 3.0.0 compile error

[Subash Jeyan]

hi,

my name is subash, from chennai india. been on slackware since about
2003, on slackware-current now.

just recently came across sbopkg and been using it for the last week or
so. looks like a nice way to browse and install libraries/applications.
thanks.

i had opencv 2.4.x on my system but since the latest digikam needed
opencv-3.0.0, was trying to compile that using sbopkg and i run into
the following error:
