Problem using qdate on EC2

[jhw]

Hi,

Have a problem with the above. Makefile is as follows

---

PROJECT = XXX

DEPS = amqp_client cowboy eredis erlcloud erlport jsx qdate syslog uuid yamerl

dep_erlport = git git@github.com:hdima/erlport.git master dep_syslog = git git@github.com:schlagert/syslog.git master dep_uuid = git git@github.com:avtobiff/erlang-uuid.git master

include erlang.mk

---

Now qdate seems to rely on a couple of other packages - I notice it pulls erlang_localtime and erlware_commons into deps

Everything works fine on my local machine, but when I try on EC2 I get the following qdate errors

Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.855.0> - {qdate,extract_timezone,1,[{file,"src/qdate.erl"},{line,481}]}, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.855.0> - {qdate,to_date,3,[{file,"src/qdate.erl"},{line,234}]}, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.858.0> - {qdate,to_date,3,[{file,"src/qdate.erl"},{line,234}]}, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.855.0> - {qdate,to_date,3,[{file,"src/qdate.erl"},{line,234}]}, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.855.0> - {qdate,extract_timezone,1, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.858.0> - {qdate,extract_timezone,1,[{file,"src/qdate.erl"},{line,481}]}, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.855.0> - [{file,"src/qdate.erl"},{line,481}]}, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.858.0> - {qdate,to_date,3,[{file,"src/qdate.erl"},{line,234}]}, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.858.0> - {qdate,extract_timezone,1, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.858.0> - [{file,"src/qdate.erl"},{line,481}]}, Feb 06 07:51:54 algo-trader-EC2 algo_trader: <0.852.0> - {qdate,extract_timezone,1,[{file,"src/qdate.erl"},{line,481}]},

If I look at line 481 in src/qdate.erl we have the following

AllTimezones = localtime:list_timezones(),

Now localtime seems to be part of the erlang_localtime app; so it seems it's not being found within the release (which I find a bit odd as it's working locally release- wise)

Probably I don't have the Makefile specified quite right; or maybe there's something slightly unusual in the qdate deps structure (esp the mismatch between the erlang_localtime package name and the localtime app name ?)

Anyway all help gratefully received

Thx!

Is that the full error? Looks like the stacktrace of an error but it's missing the beginning.

Try adding that localtime dependency to BUILDDEPS (define dep* if needed). It'll override the one in qdate.

Full stack trace for single process below (obfuscated slightly); will try the BUILD_DEPS solution, thx

Seems like I need to declare erlang_localtime in DEPS rather than BUILD_DEPS to get it included in the release (along with dep_erlang_localtime); does this sound likely/sensible/problematic ? Thx

[essen]

Right. Shouldn't be a problem for this particular application.

Thank you
