Improve the previous commit:
- log an error if some assumptions are not true
- Use TARGET_DBGSRC_DIR variable
- Do the same for ide none
Why the additional source mapping is required:
For example the cmake-example recipe refers to sources like this:
./recipe-sysroot-native/usr/bin/x86_64-poky-linux/x86_64-poky-linux-readelf \
-wi image/usr/bin/cmake-example | grep -B1 DW_AT_comp_dir
...
<560> DW_AT_name : (indirect line string, offset: 0x1da):
/usr/src/debug/cmake-example/1.0/oe-local-files/cpp-example.cpp
...
Another example is powertop:
./recipe-sysroot-native/usr/bin/x86_64-poky-linux/x86_64-poky-linux-readelf \
-wi image/usr/sbin/powertop | grep -B1 DW_AT_comp_dir
...
<561> DW_AT_name : (indirect line string, offset: 0x1da):
/usr/src/debug/powertop/2.15/src/devlist.cpp
...
For recipes with local files this works. The oe-local-files folder is
not available in the rootfs-dbg and therefore the sources are first
found in the workspace folder. GDB searches for source files in various
places:
https://sourceware.org/gdb/current/onlinedocs/gdb.html/Source-Path.html
However, for the powertop example the sources opened in the editor are
from the rootfs-dbg instead of from the workspace.
Bitbake calls the compiler with
-fmacro-prefix-map=${S}=${TARGET_DBGSRC_DIR}
where TARGET_DBGSRC_DIR defaults to "/usr/src/debug/${PN}/${PV}".
A source map which maps the recipe specific path from TARGET_DBGSRC_DIR
to the workspace fixes this.
The already existing source map for /usr/src/debug applies for all other
recipes. It finds the sources (read only) in the rootfs-dbg folder.
