To: emacs
I'm attempting to provide an emacs package for Synology NASes using the
`spksrc` toolchain (PR: https://github.com/SynoCommunity/spksrc/pull/3352).
The build fails with the following error message:
```
./temacs --batch --load loadup bootstrap
./temacs: error while loading shared libraries: libncurses.so.6: cannot
open shared object file: No such file or directory
```
`./configure` succeeds after being called like:
```

```
I'm unsure what else to collect but I'm happy to provide more logs.
A full log of the build is available here:
https://gist.githubusercontent.com/timvisher/bc2855136b3f9933599d1368c5892325/raw/8561dc1e94594f81822fa625f7e754f8e4b31fb6/emacs-arch-apollolake-full.log
(it's quite large).
`spksrc` is automatically compiling ncurses but appears, to my eyes, to be
telling emacs where to find it.
Thanks in advance!

This is described as a "Cross compilation framework", I'm not sure if
this will work (see Bug#9192)

Does your libncurses only operate on the target? Because the Emacs
build system needs to run Emacs on your build machine (hence the
difficulty with cross-compilation).

I've pointed the maintainers of spksrc to that page to see if they have any
insight related to their framework specifically.

"Does your libncurses only operate on the target?" I'm unsure what to even
Google for to answer this question intelligently. Can you give me some
pointers?

Sorry, that didn't come out clearly. What I mean is, how far apart are
your build and target machines (with respect to CPU and OS)? Can you
execute a binary built for the target on your build machine (that's
what the Emacs build system does)?
If you can, then it might just be a matter of putting the spksrc
libncurses directory in LD_LIBRARY_PATH (LDFLAGS only tells the linker
where to look, it doesn't affect the runtime).

Ah I get it then. :)
I'm not sure whether I can or not but I can certainly try and will do so
soon. Thanks so much for your input!

Success! (At least as far as the temacs step error is concerned. :) )
