Re: Perl is installed in /lib, but Config.pm indicates it is in /usr/local/lib

["Etienne" <noneofyourbus28 at hotmail dot com>]

It looks like I misspoke slightly.  I reviewed the "Config.pm" again and it 
thinks it is installed in "/usr/lib". I don't even have a "lib" directory 
under "usr" on a clean install of cygwin.

One of the lines in "Config.pm" is "archlibexp => 
'/usr/lib/perl5/5.8/cygwin'"
Also "tclConfig.sh" has the line 
"TCL_STUB_LIB_PATH='/usr/lib/libtclstub84.a'"

Just for clarification.  I have a clean install of cygwin with the packages 
necessary to attempt a build of rrdtool.  "rrdtool" is the only software I 
have that did not come from the cygwin setup.  "Perl" and "TCL" can't find 
several functions from the following packages: libartlgpl2, libpng12-devel & 
libfreetype2-devel.  If I only disable "TCL", I get the same "undefined 
reference" errors from "PERL".  The configure script finds the libraries 
with no dificulty and if I attempt a build by disabling "TCL" and "PERL" it 
works.  The only way I can get "PERL" to be included is by using the option 
"LINKTYPE=static", but I'm not sure of the consequences of that action.

Some of the errors are "undefined reference to `_art_vpath_add_point'", 
"undefined reference to `_FT_Done_Glyph'" & "undefined reference to 
`_png_create_write_struct'"

I tried copying the contents of the "/lib" directory to "/usr/lib" and 
"/usr/local/lib" as an attempted workaround.  This however did not solve the 
problem.  Even if this is a problem with "rrdtool", it doesn't explain the 
"Config.pm" and "tclConfig.sh" files.

If I am wrong and this is a problem with "rrdtool", please let me know and I 
will address it with them instead.  I did try this with the latest version 
1.2.26 and an older version 1.2.15 with the same results.

Attached is the output of the perl command line Robert sent.

I wish cygwin would use forums instead of a mailing list.

Thanks,
Etienne
