Hello again,
Trying out the erlang/APL interface (its building now!), running into
a few issues.
BTW I'm pretty new to FOSS mailing lists so if in the future you'd
prefer I'd start these as different threads, or use a different syntax
for distinguishing shell output just let me know.
First issue:
```
ldd /usr/local/lib/apl/erlang_APL_nif.so
libapl.so => not found
```
I fixed by adding "/usr/local/lib/apl" to my LD_LIBRARY_PATH.
2nd issue:
```
1> apl:init().
load called.
Executable /usr/lib/erlang/erts-10.2.4/bin/APs/APserver not found.
This
could means that 'apl' was not installed ('make install') or that it
was
started in a non-standard way. The expected location of APserver is
either the same directory as the binary 'apl' or the subdirectory
'APs' of
that
directory (the directory should also be in $PATH).
libapl initialized.
ok
2>
```
This seems related to the following previous bug report:
SVN 595
https://lists.gnu.org/archive/html/bug-apl/2015-04/msg00032.html
The function still returns 'OK'.
Third Issue (including entire session for context):
```
PATH=$PATH:/usr/local/bin:/usr/local/lib/apl
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/apl erl
Erlang/OTP 21 [erts-10.2.4] [source] [64-bit] [smp:4:4] [ds:4:4:10]
[async-threads:1]
Eshell V10.2.4 (abort with ^G)
1> c("/usr/local/lib/apl/apl").
{ok,apl}
2> apl:init().
load called.
Executable /usr/lib/erlang/erts-10.2.4/bin/APs/APserver not found.
This
could means that 'apl' was not installed ('make install') or that it
was
started in a non-standard way. The expected location of APserver is
either the same directory as the binary 'apl' or the subdirectory
'APs' of
that
directory (the directory should also be in $PATH).
libapl initialized.
ok
3> apl:statement("1 2 3 + 4 5 6").
5 7 9
[{value,[3],[5,7,9]}]
4> apl:statement("(1 2 3)∘.+(1 2 3)").
2 3 4
3 4 5
4 5 6
[{value,[3,3],[2,3,4,3,4,5,4,5,6]}]
5> apl:statement("∘.,/(1 2)(1 2)").
Segmentation fault
```
And the output of `strings apl.beam`:

It doesn't seem to be producing a core dump, haven't figured out why yet.
Thanks y'all.
Let me know how I can help!
