Subject: [PATCH 1/4] libbacktrace: avoid libtool wrapping tests
|

Content-Type: text/plain; charset=UTF-8

When `--enable-shared` is used, libtool will produce shell scripts
|
||||
instead of programs, preventing separate debug info from being generated:
|
||||
|
||||
objcopy --only-keep-debug btest btest_gnudebuglink.debug
|
||||
objcopy: btest: file format not recognized
|
||||
make[2]: *** [Makefile:2615: btest_gnudebuglink] Error 1
|
||||
|
||||
Let’s make it properly set rpath with `-no-install` flag,
|
||||
so that wrappers are not needed, as mentioned on
|
||||
https://autotools.info/libtool/wrappers.html

On platforms that do not use FHS like NixOS or GNU Guix,
|
||||
the build-id directories are not under `/usr/lib/debug`.
|
||||
|
||||
Let’s add `--with-separate-debug-dir` configure flag so that
|
||||
the path can be changed. The same flag is supported by gdb:

gdb supports multiple debug directories separated by colons:

https://github.com/bminor/binutils-gdb/blob/fcbfb25dcca625a7f999ec51d48b6fc3a32123c3/gdb/build-id.c#L136-L142
|

|

This is useful for example when using dwarffs in addition
|
||||
to debug data installed using distribution’s package manager.
