In order to resolve bug 438466, I've added a number of version bumps. The compilation takes ages and I try to have multiple versions slot'ed in combination with app-admin/eselect-opencascade to manage the env.d/51opencascade file. The only in-tree consumer is media-gfx/freecad, which loads opencascade libs on runtime. Version 6.5/6.5.0 and i.e. 6.5.5 have different symbols exported, and a Freecad 0.12.5284 installation build against 6.5/6.5.0 crashed, when opencascade 6.5.5 is active. Example, loading an dfx file. Exception (Sat Apr 27 11:42:49 2013): /usr/lib64/Part.so: undefined symbol: _ZNK18Standard_Transient8HashCodeEi Stack Trace: Traceback (most recent call last): File "<string>", line 1, in <module> File "/usr/Mod/Draft/importDXF.py", line 43, in <module> import FreeCAD, os, Part, math, re, string, Mesh, Draft This runtime crashed are not detectable by repoman. One solution would be an ABI-slot for opencascade, and force freecad rebuild after opencascade update (new portage/eapi feature). Another attempt is an eselect module to switch between opencascade installationa. With some problems: - system-wide / root access needed - LDPATH affects the state of ld.so.{conf,cache} so user-overloads have to set LD_LIBRARY_ATH - are multiple versions of opencascade really needed? - esp. version 6.3 Assuming opencascade-6.5.0 and 6.5.5 installed, 6.5.5 eselect'ed, my attempt to source the 6.5.0 env-file as regular user before freecad startup fails. eval $(sed -e 's|^\(PATH\)=\(.*\)|\1=\2:\$\1|' \ -e 's|^LDPATH=\(.*\)|LD_LIBRARY_PATH=\1:$LD_LIBRARY_PATH|' \ /etc/env.d/opencascade/6.5.0)
