Installation Susume

If after installin the !"#$%" binaries, you experience library errors while runnin itwith $pen&$"', you need to compile !"#$%" from source.()"S$N* OpenFOAMuses a library called +libsampling.so+ which has the samenameof a DAKOTA librarysee the !"#$%"-installation-dirlib directory/. %o use

!akota and $pen&$"' toether you need to compile !akota usin static libraries

SOLUTION* In the !akota 0makeLists.txt set*instead ofoption(BUILD_SHARED_LIBS "Build shared libraries?" O! #$% lineset libraries as static in the followin way*

option(BUILD_SHARED_LIBS "Build shared libraries?" O! Build stati& libraries OL'set(BUILD_SAI)_LIBS O )A)HE BOOL "Set to O to build stati& libraries" *OR)E!

In this way instead of 1.so 23 you will et static libraries 1.a/ and !akota and $&

can work toether.
