Python mapscript and AGG

[Umberto Nicoletti]

On my Ubuntu 7.04 using the distro supplied agg ( 2.4+20060719-3 ) and
latest mapserver from svn python mapscript builds and loads fine.

There is probably something wrong with you setup: maybe an old agg
version around. This command will report all agg libraries in your
system:

bash# find / -iname "*libagg*"

on mine it says:

/usr/lib/pkgconfig/libagg.pc
/usr/lib/libaggfontfreetype_pic.a
/usr/lib/libaggplatformsdl_pic.a
/usr/lib/libagg_pic.a
/usr/lib/libagg.a
/usr/lib/libaggplatformX11_pic.a
/usr/lib/libaggplatformX11.a
/usr/lib/libaggplatformsdl.a
/usr/lib/libaggfontfreetype.a

Note the _pic libraries.
Regards,
Umberto
