---++ !SuSE Version Upgrade Help : MDA

*BAD PATHWAYS MDA:*
   * it appears that the previous MDA setups have used version specific pathways to !ImageMagick, which can be fixed quite easily once the bugs have been spotted
   * one of the biggest problems with the MDA compile at present is the default pathway setup
   * if setup using the default software (!ImageMagick and g++) via =/usr/bin/=, then theoretically !SuSE version upgrades (along with !ImageMagick and g++ upgrades) should not affect MDA operation

*MDA (Errors with !ImageMagick):* ERROR MESSAGE: undefined reference to `std::_List_node_base::_M_hook(std::_List_node_base*)@GLIBCXX_3.4.14' 
   * locate the package being included (look through !TMakefile files and also notice many of them refer other !TMakefile files)
   * the magickxx package will give you problems if your pathways are incorrect (lead to an old version of !ImageMagick)
   * you will find that the version of !ImageMagick that tmk is looking for is incorrect and the default may or may not be a very old default
   * you need to change the path that the magickxx package uses to include the !ImageMagick libraries (custom configuration settings in next section)
   * the pathway will most likely have some version-specific pathway such as: 

   =config set LIBPATH $psm_pckg/[::arch_name ""]/ImageMagick-6.5.0/lib=

   =config set INCPATH $psm_pckg_generic/ImageMagick-6.5.0/include/ImageMagick=

   or 

   =config set INCPATH $psm_pckg_generic/ImageMagick-6.6.6-10/include/ImageMagick=

   =config set LIBPATH $psm_pckg/[::arch_name ""]/ImageMagick-6.6.6-10/lib=

   * as long as your default pathways are set up properly (as in the previous section) these can be written as follows:

   =config set INCPATH /usr/include/ImageMagick=

   =config set LIBPATH /usr/lib64=

*TMK (When compiling MDA):*
   * there are two places for tmk configuration files
   * this is usually where packages are defined (i.e. =magickxx=)
   * =site-config/cs.ubc.ca= in both locations corresponds to configuration on this system
   * both configuration files can be found using: =tmk -sysinfo= (tmk/user's site config directory)
   * default configuration file located in: =/cs/public/generic/lib/pkg/tmk-0.9/tmk/config/site=
   * custom configuration is (naturally) applied after default configuration
   * custom configuration can be found in: =~/.tmk/site-config/=  (again the file will be called cs.ubc.ca in this case)

*gcc/g++:*
   * sometimes the version of your compiler will mysteriously not be up-to-date
   * uses the default compiler (Check the version number: =gcc -v= or =g++ -v=)
   * this pathway is usually defaulted through your =~/.bash_profile= or =~/.cshrc= to =/usr/bin/=
   * this can be accomplished by placing =/usr/bin/= in =.bash_profile= at the front of the =$PATH= variable
   * note that this might need to be done at the beginning of the =$PATH= variable on the last export

*Remember to run the following whenever you try a possible fix:*
   * =tmk clean=       (=make clean=)
   * =tmk -reconfig=   (=make distclean=)


*Locating files and packages:*
   * Some useful and/or informative linux commands:
   * To find a file: =locate filename= (e.g. =locate Magick++.so=)
   * To find packages: =rpm -qa | grep packagename= (e.g. =rpm -qa | grep !ImageMagick=)
   * To list contents of a package: =rpm -ql packagename= (e.g. =rpm -ql !ImageMagick-6.6.1.0-4.1.1.x86_64=) 
More:
   * =ldd /usr/lib/../lib64/libMagick++.so=
   * =rpm -q --whatprovides /usr/lib64/libstdc++.so.6=
   * =rpm -q --provides libstdc++45=

*32 vs 64 bit:*
   * another issue is =-fPIC= from when we migrated to 64bit around last fall
   * PIC=position independent code (it is a default for the 32-bit platform, but not for the x86_64 platform)
   * this is why we need to add the cxx flag -fPIC
   * we can do this by adding a line to the file =...MDA/TMakefile.priv=: =lappend cxx:FLAGS -fPIC=
