Unresolved Static Variable?

[Clock]

Hi guys,

can anybody explain, what that sudden error is supposed to mean?

My EA was working flawlessly for months, but since the latest update, I get this error.

In my EA I just declare an array

CMoneyManagement mms[];

and CMoneymanagement has one static variable.

Whats wrong with that?

Thanks in advance,

Clock

Can you please post code and log that demonstrate your issue ?

I can reduce my problem all the way down to

I sure am missing something obvious here, but then again, the code has been working for the last couple months.

Thanks for any advice...

And what is the error ? The code you provided compiles and runs without problem.

Are you running error-free already with version 837?

Cause since that update, I get the error:

"unresolved static variable 'CMM::m_percent'"

in line 38 / 12, which is exactly the position of the variable "mms".

[Alain Verleyen]

Ok, you didn't mention that. I am still using build 821.

EDIT : If you don't want such problem, don't use Metaquotes Demo Server, as MT5 is automatically updated during development of new release. I suggest you to wait for official relase of a new build, and if problem is still present then write to ServiceDesk.

[Clock]

Thanks for your always fast and helpful comments!

Since my experiences with the Service Desk where rather unsatisfying so far, I was hoping for a quick solution right here. But if it's beta-version related (if you wanna call it that), then I'll have to go the other route.

Concerning Metaquote Server: they simply have the most satisfying price history of all the servers I tried. Also, switching back is not possible, if I'm right (except of course for a total re-install).

"Fine"!

So now that Version 842 is officially out, does the code still compile at anybodies else's PC?

For me, it's dead now, cause I cannot even go back to the last version.

Or: can anybody somehow provide me an earlier version?

Thanks in advance,

It's clearly a bug. The simple fact to declare a static variable in a class results in this error. Did you reported it to ServiceDesk ?

I did last week already.

My complain vanished from my profile within 2 days, so I thought they already recognized it.

Now, I reposted my complain.
