Todd,

are you shure that you are building and linking libkexiv2-svn against svn-
exiv2 (right headers and libs)?

Hi Jens,

You're quite right.  How embarassing.  I'm not sure how I missed
that.

I'll look into why it's not picking up my SVN versions in /usr/local, but
for now I've just modified my CMakeCache.txt files.

Thank you and my apologies,

Todd

Hi Jens,

You're quite right.  How embarassing.  I'm not sure how I missed
that.

I'll look into why it's not picking up my SVN versions in /usr/local, but
for now I've just modified my CMakeCache.txt files.

Thank you and my apologies,

Todd

For me it didn't pick the svn lib because it checked the system pkg-config path first and found the distro lib there. So I had to adjust it with PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:other paths.. and then it was ok. I'm on Fedora 13 x86_64 btw.

Marty

Thanks Marty.  I did that and it seemed to work for some of the builds
but strangely not for libkexiv2, digikam, and kipi-plugins.

I think the Gentoo cmake helper macros are falling back to pkg-config
for some things but not others?

Thanks,

Todd
