[OpenWrt-Devel] gdb compiling issues

[Flunt Le Jeune]

Hi all,

When I tried to compile a build of OpenWRT I encountered some issues
regarding the gdb package.

STEPS TO REPRODUCE:
1. git clone https://www.github.com/openwrt/openwrt
2. make menuconfig

- Target System (x86)
- Development ---> gdb Enable
- Development ---> gdbserver Enable
- Advanced configuration options (fordevelopers) ---> Toolchain
Options ---> Build gdb Enable
- Advanced configuration options (fordevelopers) ---> Toolchain
Options ---> GCC compiler version (gcc 5.x)
- Advanced configuration options (fordevelopers) ---> Toolchain
Options ---> C Library implementation (Use glibc) (Version 2.26)

3. make V=s

Has someone encountered this issue before?
If yes, how did you fixed this?
