[Cin] Questions about compiling

[Andrea paz]

- To compile new releases from source, I use the following ./configure:

./configure --prefix=/usr --with-jobs=8 --without-oss
--with-single-user –with-booby

But I get warnings I don't understand:

[paz at archpaz cinelerra-5.1]$ ./configure --prefix=/usr --with-jobs=8
--without-oss --with-single-user –with-booby
...
configure: WARNING: you should use --build, --host, --target
configure: WARNING: invalid host type: –with-booby
...

What are the best ./configure options to use for compiling?

- Another question:
I noticed the following warning when compiling. It is a warning that
repeats itself dozens of times before continuing:
...
./libavutil/mem.h:342:1: warning: ‘alloc_size’ attribute ignored on a
function returning ‘int’ [-Wattributes]
  342 | av_alloc_size(2, 3) int av_reallocp_array(void *ptr, size_t
nmemb, size_t size);
      | ^~~~~~~~~~~~~
...

Everything's working fine, so I don't think it's important.

PS: Great idea the smooth button in the mask tool!
PPS: Have you heard of the new -O1g instead of -O1?
