That could be explained if gdb and Eclipse simply have different heuristics
for looking up source files, given a name without directory specification.

Hmm, indeed some parts of the debug info appear to have the full file name.
When I build with $builddir = $srcdir,
"readelf --debug-dump src/roff/troff/troff" contains
<0><1ef06>: Abbrev Number: 1 (DW_TAG_compile_unit)
DW_AT_stmt_list : 17622
DW_AT_entry_pc : 0 0
DW_AT_name : (indirect string, offset: 0x8865): input.cpp
DW_AT_comp_dir : (indirect string, offset: 0xf48):
/home/bruno/groff/src/roff/troff
DW_AT_producer : (indirect string, offset: 0x9e2): GNU C++ 3.2.2
(Mandrake Linux 9.1 3.2.2-3mdk)
DW_AT_language : 4 (C++)
The File Name Table:
Entry Dir Time Size Name
1 0 0 0 input.cpp
2 0 0 0 /usr/include/bits/waitstatus.h
and when I build with $builddir != $srcdir, I get absolute pathnames
everywhere:
<0><1eefa>: Abbrev Number: 1 (DW_TAG_compile_unit)
DW_AT_stmt_list : 18891
DW_AT_entry_pc : 0 0
DW_AT_name : (indirect string, offset: 0x8b0a):
/home/bruno/groff/src/roff/troff/input.cpp
DW_AT_producer : (indirect string, offset: 0x9e2): GNU C++ 3.2.2
(Mandrake Linux 9.1 3.2.2-3mdk)
DW_AT_language : 4 (C++)
The File Name Table:
Entry Dir Time Size Name
1 0 0 0 /home/bruno/groff/src/roff/troff/input.cpp
2 0 0 0 /usr/include/bits/waitstatus.h
I'll see whether I can configure Eclipse or g++ so that this works...
