I have about 12 different separate programmes. While compiling
only one of them, it gives as warning as below:
/usr/include/dmd/phobos/std/mmfile.d(344): Deprecation: alias
core.sys.posix.sys.mman.MAP_ANON is deprecated - Please use
core.sys.linux.sys.mman for non-POSIX extensions
I used `grep` tool to see any of my library files or programme
code have any use of this library.
grep mmap -r
Result is that binary files of all 12 different programmes have
mmap in them. I wondered maybe a Phobos or druntime uses it. Used
grep in `/usr/include/dmd` folder as well. As far as I see in the
file list, unless mmap is directly imported, no other file uses
it.
The only thing different about that specific programme is that it
uses curl. Does anyone know why that deprecation message is
seen while it is not used anywhere? Because that executable gives
following error on GDB, and I am thinking that maybe that is its
problem.
Program received signal SIGUSR1, User defined signal 1.
