undefined reference to `gt_pch_nx_tree_code'

[Aravinda <aravindakidambi at gmail dot com>]

Hi,

I am writing a new pass for gcc that uses the GTY markers,
1. I have included the source file in GTFILES_H in gcc/Makefile.in.
2. I have the gt-path.h mentioned in the compilation for source file
3. I have the #include "gt-path.h" at the very end of the code of source file.

I see the gt-path.h is getting created in the build/gcc directory. But
I am getting the below error. Is there something I am missing in the
Makefile, I tried to look at a similar example of tree-mudflap.c that
uses GTY markers, I do not see any difference in the steps I have
followed.?I havent done gcc dev before, so I'd really appreciate any
help in this regard.

main.o tree-browser.o libbackend.a ../libcpp/libcpp.a
../libdecnumber/libdecnumber.a ../libcpp/libcpp.a
../libiberty/libiberty.a ../libdecnumber/libdecnumber.a?? -lmpfr -lgmp
-rdynamic -ldl
