Frequently Asked Questions

Package uuid not found.

If the configure script complains about the uuid package to be missing, you need to install the e2fsprogs (and e2fsprogs-devel) from your system-installer (version 1.38 or later).

Building on SL(C)4 and SL(C)5 (gcc345) on 64bit with xmgrace.

Do not rely on the pre-built xmgrace package, as this only ships with static libs, to work with iAIDA you need to have shared/dynamic libs. So you need to download the xmgrace source and build it from there.

When you build grace, you have to set the environment variable CFLAGS to -fPIC before starting the build, otherwise you will get a linker error when building the iAIDA lib. The following worked for me:

					CFLAGS=-fPIC ./configure ...
					CFLAGS=-fPIC make
				

HBook on 64bit platforms

The steps below are only valid for iAIDA versions 1.0.X.

If you request to use CERNLIB on 64bit architectures, static libs will be automatically build (if you want/need to build iAIDA also with support for ROOT, you have to provide static libs for ROOT as well).

If you need shared libs on that platform in conjunction with CERNLIB, you will have to use a 32bit build of CERNLIB and re-build the (shared) iAIDA libs. To do this, you need to install the 32bit version of CERNLIB, then configure and build the iAIDA libs with the followingcommands (after unpacking the tarball):

						linux32 ./configure --prefix  \
						--with-cernlib  \
						[possibly other options here] 
						linux32 make CXXFLAGS='-m32' FFLAGS='-m32' 
						linux32 make CXXFLAGS='-m32' test  # optional 
						linux32 make CXXFLAGS='-m32' install
					

Don't forget to build your application (and all other libs) in the same way and run your application with linux32 as well :-)

HBook with gcc4.3 on SLC5 (64bit)

The steps below are only valid for iAIDA versions 1.0.X.

If you are using HBook with gcc4.3 on SLC5, you need to use a build of CERNLIB with the official (from GCC) gcc4.3 compiler, the one which comes with SLC5 is broken.
