Hello,
I confugure and make musl with following= :

CFLAGS=3D-g CROSS_COMPILE=3Driscv64-unknown-linu= x-gnu- ./configure --prefix=3D/home/u/ws/musl/install --exec-prefix=3D/home= /u/ws/musl/install --syslibdir=3D/home/u/ws/musl/install

create the executable with: ./install/bin/musl-gcc -g test.c

Then I tried to debug:
$ qemu-riscv64 -g 1= 234 ./a.out
then launch gdb:
$ riscv64-unknown-linux-gn= u-gdb a.out

but after I tried to target remote, gd= b oops and tell me:
```
gdb) target remote:1234
Remote debugging using :1234
warning: Unable to find dyna= mic linker breakpoint function.
GDB will be unable to debug share= d library initializers
and track explicitly loaded dynamic code.<= /div>
0x0000004000850ae2 in ?? ()
```

I tried to set sysroot but does NOT take effect:
```
(gdb) set sysroot /home/u/ws/musl/install/
warning: Un= able to find dynamic linker breakpoint function.
GDB will be unab= le to debug shared library initializers

(gdb) set sysroot /home/u/ws/musl/ins= tall/lib
warning: Unable to find dynamic linker breakpoint functi= on.

and track explicitly loaded dynamic code.
```
I checked the a.out
```
$ riscv64-unknown-linux-= gnu-readelf -l a.out
......
  INTERP    =     0x00000000000001c8 0x00000000000101c8 0x00000000000101c8
                 0x0000= 00000000002d 0x000000000000002d  R      0x1
&= nbsp;     [Requesting program interpreter: /home/u/ws/musl/instal= l/ld-musl-riscv64.so.1]
......
```
And = I can run with qemu directly: $ qemu-riscv64 ./a.out, this works, but = why I can not debug with gdb? Who can help me out? Thanks in adv.
