Re: [EXTERNAL]Building GNU APL with clang
I'm pretty sure tge use of auto_ptr can be changed to unique_ptr here. I think I used auto_ptr because I wanted it to work on versions of C++ which didn't support unique_ptr.

Re: [EXTERNAL]Building GNU APL with clang
Hi, thank you all for discussing this. To address at least some of the issues i have: 1, removed typeof() entirely, and 2. replaced *std::auto_ptr<>* with *std::unique_ptr<>* as proposed on the internet. I am not entirely sure about 2. though. It was only used twice in emacs_mode and once in apl-sqlite.cc. Unfortunately I am lacking any emacs experience and can therefore not easily test the changes. Maybe Elias wants to have a look at it (IMHO some uses of *auto_ptr* can be avoided entirely). If my changes should break anything then please let me know. *SVN 1736*.

Re: [EXTERNAL]Building GNU APL with clang
Hi, thank you all for the rapid replies. Shortly after posting, I figured out how to set clang-11 as my default cc and c++ on my Devuan x86_64 laptop, and it builds perfectly there. So strange; I wonder what is different about the Termux clang environment. (It is a native ARM aarch64 Linux env, hosted within Android, using its own package repositories). I wish they had just stuck with gcc, it was building fine on my older phone :(. (I know there's an Android build mode outside of Termux, but I was trying to go with what I knew worked. Oh well.)

RE: [EXTERNAL]Building GNU APL with clang
Hi Russ – On OpenBSD, clang has been the default compiler for many years. I routinely build APL trunk on OpenBSD, and never had any problems so long as I add -std=gnu++11 to CXXFLAGS. I just rebuilt APL from a clean SVN checkout and it built without issues. I am using clang-16.0.6.
