Due to some restrictions we are working with a fairly old tms470 tool chain which would be probably impossible to update at this point, it is version 4.1.1. I am archiving a listing of about 2000 object files into a main library and then linking that library with any other libraries that are needed into the executable. Here is the command line:
lnk470.exe -b -a -x -q -w -c -priority -o output/bin/my_outfile.out -m output/bin/my_mapfile.map host_link.lcf output/lib/my_mainlib.lib many_other_libs.lib
with "many_other_libs.lib" being about 50 or so other .lib files all seperate. In my link.lcf file I have a something as shown below:
.FRAME_BUFFER : type = NOLOAD, align = 0x00100000
{
*(.FRAME_BUFFER)
output/lib/my_mainlib.lib<FrontDisplayBuffer.obj> (.bss)
} > ExternalRAM
The linker gives me the following warning:
>> host_link.lcf, line 178: warning:
output/lib/my_mainlib.lib<FrontDisplayBuffer.obj>(.bss) not
found
The object does have a .bss section, here is the output from ofd470 of the FrontDisplayBuffer.obj:
DEFINITION OF SECTION ".bss"
--------------------------------
Physical addr = 0x0, Virtual addr = 0x0, Size = 0x25820,
Number of relocation entries = 0, line number entries = 0
Flags = 0x280, Memory Width = 0 bits
[ Alignment = 4 units, Type = BSS ]
File pointers : Raw data at 0x0
: Relocation at 0x0
: Line # entries at 0x0
and here is the evidence that the FrontDisplayBuffer.obj is in the library using ar470 -t:

Just in general I am seeing weird behavior with the linker finding explicit objects/object sections in this large my_mainlib.lib library. What is the correct way that you should tell the linker where these object files are located? I have had very different results when having the linker file placed before or after the my_mainlib.lib on the command line also have had other different behavior (objects that were before found but now not found) when using --search_path and --library. The assembly tools documentation is a little confusing to me as to when these different options are necessary. For reference I am archiving the objs using the command:
ar470.exe -vr1 output/lib/my_mainlib.lib obj_files
