qt5.5 cross-compilation gstreamer error

unnamed

on my target :)

SGaist

Did you re-do the configuration after installing the missing dependencies ?

unnamed

yes, many times.
every time i change something in my setup i do
make clean
new ./configure command to try with different options
make

SGaist

make clean is not enough, you need to start from a clean state.

I recommend out of source builds so when something goes wrong you can just nuke the folder and you don't pollute the sources.

unnamed

ok, i'am going to try today, so i need to remove whole Src folder, redownload and rerun whole process ?

//edit
same thing happened. i have completly removed Src folder, and redownloaded it with qt "maintaince tool"
i'am stuck at:

What distribution are you running on your Pi ?

unnamed

newest jessie

hmm i searched my mac for pcre libs as i think that something confuses qt and i found one occurence of libpcre16 located in /brew2/local/Cellar/pcre
its dependency for something installed via homebrew
is it possible that its source of my failures ? :)

SGaist

That possibly can interfere. Note that I'm more used to cross-compilation from Linux host. It make things way easier.

unnamed

after 2 weeks got it working... tried on my macbook air with almost clean el capitan :)
to many libs, projects, work stuff on my mac pro and i can't find the problem, maybe something connected to homebrew (something like apt-get in linux) installations.

for anyone who stumble upon this thread that should be a good lesson -> clean system = simple compilation :)

thanks for help SGaist :)

SGaist

Hi.
I encountered same problem, would you please tell what did you do to solve the problem?
By the way, what do you mean by " i have added -lpcre to pkg-config file o glib :)"?
Thanks in advance.
