Qhull 2012.1 2012/01/26 6.3.0.1465

Bug fixes

• Fixed qset.c for -fno-strict-aliasing. This gcc option is no longer needed (disallow two pointers of differing types to the same memory location)
• Fixed error in qh_setappend_set if first set full and second set empty
• qh_setdelnth, qh_setdelnth_sorted: fixed wording of error message
• qh_setcheck: error message listed size and max backwards.
• qh_setequal: Allow NULL set as documented
• qh_setindex: Allow NULL set as documented
• qh_settemppush: report error if NULL

Code changes

• Add testqset: low level test of qset.c with mem.c
• qh_setendpointer: Implements QSet::endPointer()
• Assigned unique error code for qh_gethash

Build changes

• Added qhull.dll(.so) for Octave and other Debian builds The global data structure qh_qh is statically defined (no qh_QHpointer) Linked user_eg2 with qhull.dll (libqhull.so) instead of qhullstatic Added qh_dllimport to libqhull.h for qhull.dll with MSVC Changed qhull-app-shared.pri to use libqhull (without qh_QHpointer)
• Renamed libqhull6.so to libqhull6_p.so Renamed qhull6.dll to qhull6_p.dll The _p libraries (e.g., libqhull6_p.so) require -Dqh_QHpointer Renamed qhull6.vcproj to libqhull6_p.vcproj Added libqhullp/libqhullp.pro for shared library (libqhull6_p.so) Added qhull-app-sharedp.pri for shared libraries with qh_QHpointer
• Install libqhull/*.htm files into include/libqhull
• Removed libqhull/qhull.h-deprecated
• Other changes to Makefile builds Added 'make qtestall' as a smoketest of each qhull program src/libqhull/Makefile: Use 'ar -rs ...' instead of ranlib src/libqhull/Makefile: Fixed targets for cleanall
• Other changes to DevStudio builds Moved pdb files for qhull libraries to lib/ AdditionalIncludeDirectories: Removed ../src/libqhullcpp Use build-cmake/ for the DevStudio CMake build
• Other changes to Qt builds Renamed qhull-libsrc.pri to qhull-libqhull-src.pri
• Added explicit d2u conversions to qhull-zip.sh
• Fixed \n vs. \r\n issues for Windows source files
  
  Draft of Debian/AutoConf build (untested)
• Adjusted the Makefile.am's for the new directory structure.
• Added testqset to bin_PROGRAMS
• config/bootstrap.sh copies program sources into src/libqhull
• Kept qh_QHpointer=0 (static global data structure, qh_qh). It is faster. Planning a new interface (qhull7?) which passes qh_qh as a parameter
• Added config/changelog from the 2003.1 Debian build
• Moved the debian/patches directory to config/ Optional patches to change smoketest message and turn on qh_QHpointer
• Deleted the debian directory. It was the old Debian build from 2003.1 Rafael Laboissiere's config directory replaced this build..
• Deleted Make-conf.sh (also the old Debian build)
