I didnt mean to embarass you Abla..Sorry..

Evin bulunması zor olabileceğini anlatıldık.

Lets start with literal analysing of your sentence ;

Evin bulunması ---> its [house] being found

zor olabileceği ----> its [being found] being difficult

note ; there are three verbs or verb like situation here which are "bulunmak", " zor olmak " and " anlatılmak " so we need to take all verbs into consideration when we combine them. In other words we need to put appropriate endings to tie them up together.

So lets bit modify your sentence to make it right.

Evin bulunmasının zor olabileceği bize anlatıldı.[or "izah edildi"]

so what you missed was "nın" and what you put extra was "ni" [olabileceğini]

 In my opinion we cant , as it refers the past tense.

. Sometimes için takes -mek-infinitive with a possessive suffix and sometimes without, like in

        İngilizceyi çevrimiçi [internette] öğretmek için

         Silahlı kimse adam  hareket etmememiz için bizi uyardı.

What is the difference?

Lets look at your original translation ;

The man with the gun warned us not to move. Silahlı kimse hareket etmemizden uyardı

if we translate your translation into english that would be ;

the man with the gun warned us from our moving..--> that wouldnt make sense in english i guess.

we use "için" to join two action above, to warn and to move.

  warned us to not to move ---> hareket etmememiz için --> the second "me" indicates "negative " its like " for us not to move "

another example ;

Partiye gitmememiz için bizi odaya kilitledi ---> He/she locked us in the room for us not to go to the party.

gitmememiz için --> for us not to go

Gökuyum, I would go for " Çok eğlenceli olmuş olmalı " or if it is an occasion such as birthday party we can say " Çok eğlenceli geçmiş olmalı"

2: Doesn´t it bother you when there are two dative words in a queue, like in Çocuk sigarayı bırakmaya çalışacağına söz vermek zorunda idi. What if there was still annesine before söz vermek?

Yes it does bother me abit, alternatively you can say;

Çocuk sigarayı bırakmaya çalışacağına dair annesine söz vermek zorundaydı.

dair = concerning, about

so we have still two dative case sorry..i like datives..it just sounds to my ear better..your sentence was not wrong but at first look this way sounded better to me.

lets check your sentence again;

The boy had to promise that he will try to stop smoking. Çocuk sigara içmekten vazgeçmeye çalışacağına söz vermek zorunda idi.

as I said thats not wrong..may be the "vazgeçmeye " bit  wasnt welcomed by my ears...

Ok. Hindistan I found out what the term "marker" means.

Its a sort of colourful chemical that is injected into fuel [oil,diesel,biodiesel] to mark it aiming to prevent the illegal oil. That chemical can not be copied. That is gonna be used country wide by goverment. So that the loss of tax because of illegal oil will supposed to finish by doing this. So as a term it is used as "marker " therefore we can say "markersız"

TDK [Turkish Language Association] should find a new word for it hopefully. 

Its quite normal for learners to having trouble to pick up which one for which case.

 Söylemek ---> to say, to tell   as you know, for example ;

Bana derdini söyle ---> Tell me your problem.

Sana bir şey söyleyeceğim ---> I will tell you something. [ I will say something to you]

for the first  sentence above we can replace "söylemek" with "demek" but that wouldnt sound good.

for the second sentence that would sound ok. if we replace it with "demek"

Sana bir şey diyeceğim.

 Anlatmak ---> its more like " to explain or describe ,something to somebody " its not just telling. You go more into details when you use "anlatmak"

Bana sorununu anlat ---> Bana evini anlat ---> Describe your house to me. [tell about your house]

Dont worry Abla,  these usages will sink into your mind as you practice and study them. One day you will use them automaticly in the right place without thinking.

 what is "markersız ?" i couldnt make it sense.
