Wesnoth 1.16.7 Compilation error

[alberic89]

Hello,
A bug have occurred when I have tried to compile the 1.16.7.
The error :

Spoiler:

Code: Select all

In file included from <command-line>:

make[2]: *** [src/CMakeFiles/wesnoth-client.dir/build.make:2903: src/CMakeFiles/wesnoth-client.dir/gui/dialogs/multiplayer/mp_create_game.cpp.o] Error 1

I use :

Code: Select all

gcc (Debian 10.2.1-6) 10.2.1 20210110
GNU Make 4.3
cmake version 3.18.4

and an arm64 (aarch64) OS (Raspberry Pi OS).

I don't have retried for the moment.

I don't think there's a whole lot we can do about this in Wesnoth since it's an internal compiler error - the compiler itself segfaulted for some reason.

As a workaround you could compile with clang.

I believe for cmake you add the option -DCMAKE_CXX_COMPILER=clang
