Hello,
I was trying to compile emacs 27.2 for some testing, but the build
fails. I am not sure what I am missing, as this is the first time I
compile Emacs from source manually. Any hints are appreciated.
What I did:
$ git clone --bare <url> /opt/src/emacs.git
$ cd /opt/src/emacs.git
$ git worktree add ../emacs-27.2 tags/emacs-27.2
$ cd ../emacs-27.2
$ make
...
CC sysdep.o
sysdep.c:1821:22: error: variably modified ‘sigsegv_stack’ at file scope
1821 | static unsigned char sigsegv_stack[SIGSTKSZ];
| ^~~~~~~~~~~~~
make[2]: *** [Makefile:406: sysdep.o] Error 1
See the attachment for full output of `make'.
