Message-ID: <CAHa53uwH_Y=KHjO67ae7+J0Vkoo7ihALr6=ydraxjjbP1TDx8g@mail.gmail.com> (raw)

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:

Notably LDFLAGS appears to contain a directory which contains
libncurses.so.6

```

```

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!
