[Plplot-devel] linking, build issues

[Geoffrey F. <fu...@ga...>]

BTW, I reconfigured --enable-dyndrivers, but it still doesn't build:

make: *** [pltcl] Error 1

I haven't had a chance to review the core reasons for the build
failures, but superficially it looks like there's been some changes to
the ldflags make macro, which haven't been completely worked through
in all the cases.  

I can't really drop itcl/itk for my current need, because this is an
itk based app which seeks to embed a plframe (inside a PLXWin).

Okay, I stuided this a little after getting some zzz's, and its not
what I thought.

I got thorugh this by setting LD_LIBRARY_PATH so that it would find
the prefix area that I'm building against.  My memory is foggy, did we
ordinarily have to do this before?  Intuitively, I would expect the
software to build without LD_LIBRARY_PATH set, but probably not run
without it set (for prefixen not listed in ld.so.conf).  But usually I
have my LD_L_P set to the prefix in my .cshrc, but this came up this
time because I'm setting up a new prefix area.
