Bug ID: 105678
Summary: Undefined reference to stacktrace standard library
Product: gcc
Version: 12.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: fcolecumberri at hotmail dot com
Target Milestone: ---
I'm trying to test the stacktrace C++23 feature by creating the next program:
```c++
#include <stacktrace>
int main(){
std::stacktrace::current();
return 0;
}
```
using the next g++:
```
Using built-in specs.
COLLECT_GCC=g++
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-pc-linux-gnu/12.1.0/lto-wrapper
Target: x86_64-pc-linux-gnu
Configured with: /home/franky/Descargas/gcc-libs/src/gcc/configure
--enable-languages=c,c++,ada,fortran,go,lto,objc,obj-c++ --enable-bootstrap
--prefix=/usr --libdir=/usr/lib --libexecdir=/usr/lib --mandir=/usr/share/man

--enable-libstdcxx-backtrace=yes
Thread model: posix
Supported LTO compression algorithms: zlib zstd
gcc version 12.1.0 (GCC)
```
Notice I added the `--enable-libstdcxx-backtrace=yes`
with this command:
```bash
g++ -std=gnu++2b cpp_file.cpp
```
And I get the next output:
```
/usr/bin/ld: a-cpp_file.o: in function `std::stacktrace_entry::_S_init()':
cpp_file.cpp:(.text._ZNSt16stacktrace_entry7_S_initEv[_ZNSt16stacktrace_entry7_S_initEv]+0x4a):
undefined reference to `__glibcxx_backtrace_create_state'
/usr/bin/ld: a-cpp_file.o: in function

undefined reference to `__glibcxx_backtrace_simple'
collect2: error: ld returned 1 exit status
```
Maybe I am missing something, maybe the documentation is missing something, or
maybe this is still very experimental.

--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
I suspect it is missing from the linker script for versioning.
Using -static-libstdc++ should be a workaround.

just tried
```bash
g++ -std=gnu++2b -static-libstdc++ cpp_file.cpp
```
but same result.

As documented at https://gcc.gnu.org/gcc-12/changes.html#libstdcxx "requires
linking to an extra library"..
You need -lstdc++_libbacktrace although I haven't put that in the libstdc++
manual yet, and the name of that library might change (it should at least be
consistent with the --enable-libstdcxx-blah configure option to build it, and
currently they're not consistent, which was dumb of me).

(In reply to Francisco from comment #0)
> Maybe I am missing something,
Yes, you need to link to the extra lib that gets built by the extra configure
option you gave.
> maybe the documentation is missing something,
Yes, it is.
> or maybe this is still very experimental.
Yes, it is.

--- Comment #5 from Francisco <fcolecumberri at hotmail dot com> ---
I have no idea of what's happening, I have tried
```bash
g++ -std=gnu++2b -lstdc++_libbacktrace cpp_file.cpp
```
and
```bash
g++ -std=gnu++2b -L/usr/lib/libstdc++_libbacktrace.a cpp_file.cpp
```
(also tried with -static-libstdc++)
and I just got the same result.
However if I use `readelf` over /usr/lib/libstdc++_libbacktrace.a I can see the
symbols there.

Try:
g++ -std=gnu++2b cpp_file.cpp -lstdc++_libbacktrace
That is put the library after the source file. Static libraries are always
order depedendent.

NOW IT COMPILE!!!
(And now I have learned a new thing about static linking)
Then it crashes on `segmentation fault (core dumped)`,
since I know this is still experimental, I assume this is on the expected
scope.
Thanks a lot.
I am going to mark it as resolved since the `Undefined reference` stuff is
resolved.
Thanks

http://c-faq.com/lib/libsearch.html is the reference I usually give.
I'm reopening this until I've updated the docs.
