Given this, is there any reason to continue our > preference from mpir over mgp? Not really, something we should change. Although, the preference is only in alkimia. KMyMoney contains two references to gmpxx.h: kmymoney/mymoney/mymoneymoney.cpp 21:#include <gmpxx.h> kmymoney/mymoney/payeeidentifier/ibanbic/ibanbic.cpp 11:#include <gmpxx.h> and on my distro, mpir is not included so apparently I use gmp for a long time already. > Back to the code, without mpir installed, libalkimia seems to find gmp > with no problem, but fails later in cmake (which I'll discuss in a > separate thread.)

I don't see any reference to GMP nor MPIR in the KMyMoney build instructions: thb@sy-346-nb /home/thb/devel/kmymoney (master)$ find -name CMakeLists.txt | xargs grep -i gmp thb@sy-346-nb /home/thb/devel/kmymoney (master)$ find -name CMakeLists.txt | xargs grep -i mpir thb@sy-346-nb /home/thb/devel/kmymoney (master)$ I'd try the following: - Start with a complete empty build directory and see if that makes a difference. - In case that does not help, try running cmake with option --trace-expand (and maybe redirect output of stdout and stderr to a file). Try to see what cmake does, when it fails. -- Regards Thomas Baumgart ------------------------------------------------------------- C makes it easy for you to shoot yourself in the foot.
