where do I find these unresolved symbols

[Mirko <phaccount at nycap dot rr dot com>]

Hello,

I am  porting a plasma simulation code from linux to cygwin (my windows 
box is 4x faster than the linux box I can get).

During the linking phase I am getting an error message about unresolved 
symbols.  I am a bit puzzled about some of them (tcl/tk, xpm) because I 
believe that I am pointing to the correct libraries (so much about my 
knowledge of pointing to libraries), and baffled by others, as I don't 
have a clue where they may be coming from.

I am attaching the output of the linker separately, but here is a 
breakdown of the errors:

___getreent

_sind, _cosd (I do have -lm on the command line)

_Tcl_Eval, Tcl_Create_Command (funny, but I find the first one in the 
libtcl.a, not the second)

_Tk_NameToWindow (I do have -ltcl, -ltk, and I believe -L is set 
correctly on the command line)

_BXG_Write_2,3D (What library does this belong to?)

_XpmWriteFromPixMap (I have the Xpm-NoWindows package, but I don't see 
any libxpm.a on the system, only s,cxpm.exe)

I am using the most recent version of all the packages (sorry, I don't 
have the output of cygcheck with me right now)

Clues? comments (like go away, and don't bug us :-)

thanks,

Mirko
