Problem about install gdb5.0 configured with WDB support under cygwin.

[<shanyecunfu888 at sohu dot com>]

Hi there,

   I am running a Win2000 host system and installed Cygwin successfully. The building of a GCC cross compiler was also  successfully for a powerpc-vxworks based target system.
   Now I want to install GDB on my host(on Cygwin) and build it with wdb support for my target. By using  GDB5.0 ,patched by Mr.till's file named "gdb-5.0-wdbpatch-1.1",the configure script " <dirPath>/configure --prefix=/gdb5.0 --target=powerpc-vxworks --enable-vxwdb" works fine. But when I want to build it, I get the following error message:

gcc -g -O2        -o gdb.exe main.o libgdb.a vx-wdb/libwdb.a   ../bfd/libbfd.a .
./readline/libreadline.a ../opcodes/libopcodes.a ./../intl/libintl.a ../libibert
y/libiberty.a `if test -r ../libtermcap/libtermcap.a; then echo ../libtermcap/li
btermcap.a; else echo -ltermcap; fi`     -lm  ../libiberty/libiberty.a -luser32

    I really don't know where to search for the error.It seems the building process of gdb.exe cannot find libwdb.a and libgdb.a's function reference,but how the two librarys can be generated correctly? Thank you for your help.
