Hello to all ....
I'm on Funtoo "Stable" 64 bits (with xfce4 and kde / plasma-5)
Trying to install digikam, I had to unmask the last version in Portage (media-gfx / digikam-5.3.0), Because with the 4.4.0-r1 I had problems with kde-frameworks / baloo).
I made several attempts .... I finally managed to install digikam; But I had to change the local use flags for sci-libs / HDF5 disabling "mpi" and "threads".
Rightly so ... or is there a way to use multithreading and multiprocessor support around sci-libs / HDF5?
Excuse me (but I'm curious to understand:) ... and thx for info :)

section of the Gentoo Linux x86 Handbook (architecture is irrelevant):


Then i've unmasked latest version:

* media-gfx/digikam 
    Available versions:   
    (4)    4.4.0-r1^t (~)4.14.0-r1^t 
    (5)    (~)5.3.0^t

Then trying to emergedigikam-5.3.0 i obtain:

ci74771ht ~ # emerge digikam 
Calculating dependencies... done!

(dependency required by "digikam" [argument]) 
ci74771ht ~ # 

Then with in package.use: 

sci-libs/hdf5 -mpi -threads


digikam successfully compiled _'_


So not using "threads" and "mpi", HDF5 can run only with a single thread i think .... _'_


My question: is right that HDF5 can runs only with single thread instead multithread ?


Just a curiosity _'_ :)

thx for output.

So, cxx USE flag is enabled by default in profiles. threads USE is not. hdf5 ebuild cannot use both. Do you have threads enabled globally?
