             Bug #: 14515
           Summary: BFD update cause undefined reference to
                    `bfd_und_section'
           Product: gdb
           Version: 7.5
            Status: NEW
          Severity: critical
          Priority: P2
         Component: build
        AssignedTo: unassigned@sourceware.org
        ReportedBy: ray_linn@hotmail.com
    Classification: Unclassified


I am using MinGW64 to compile the GDB 7.5 ( GDB 7.4.1 was completed without
error), and finally I got the error as following:

elfread.o:elfread.c:(.text+0x896): undefined reference to `bfd_und_section'
elfread.o:elfread.c:(.text+0xb1a): undefined reference to `bfd_abs_section'
elfread.o:elfread.c:(.text+0xb4a): undefined reference to `bfd_abs_section'
elfread.o:elfread.c:(.text+0xf42): undefined reference to `bfd_abs_section'

checking the BFD source code, in the bfd.h, the following lines exists in GDB
7.4.1 but was deleted in GDB 7.5.1


/* The absolute section.  */
extern asection bfd_abs_section;
#define bfd_abs_section_ptr ((asection *) &bfd_abs_section)
#define bfd_is_abs_section(sec) ((sec) == bfd_abs_section_ptr)
/* Pointer to the undefined section.  */
extern asection bfd_und_section;

without the declare, of course elfread.c can not be linked

I don't see any references to these symbols either in elfread.c or
in bfd.  Now it uses, e.g., bfd_und_section_ptr.
I'm looking on the 7.5 branch.
Do you have local changes or something like that?
If not can you find exactly where the undefined reference is coming from?
And/or verify that you have the right files?

I found the root cause, previous GDB 7.4.1 installed the bfd.h in my
/usr/local/include, so once this folder was in include path, it will cause the
conflict. 


Manaully remove the GDB 7.4.1 files, everything is ok, but no sure why make
uninstall does not work.
