Converting libqhull to libqhullr
Todo
3>..\..\src\qhullr\unix_r.c(39) : warning C4273: '_isatty' : inconsistent dll linkage
3> C:\Program Files\Microsoft Visual Studio 8\VC\INCLUDE\io.h(209) : see previous definition of '_isatty'
Redo usage note for qhullr.cpp
Add qhull-libqhull-src.pri to libqhull.pro
Remove #SOURCE from libqhullr.pro
It changes the RelativePath to one fewer
From
RelativePath="..\libqhullr\stat_r.h" />
To
RelativePath="..\..\libqhullr\stat_r.h" />
---
How is roadTest.h done, it has the right path in vcproj
---
/*** uncomment here and qhull_a.h
if string.h does not define memcpy()
#include <memory.h>
*/
---
Run through valgrind
---
Fix or "sample code" in user_r.h
and in user_r.c
qh_call_qhull(qh, void )
template for calling qhull from inside your program
--
Try with and without qh_NOmem
==============
Steps
Build qhullr.sln from qhull_all.sln
Shadow build isn't working for header files. libbqhull and libqhullr
RelativePath="..\..\src\libqhull\
Doesn't create qhullstatic_rd.lib
Inconsistent dll linkage for _isatty
include only libqhullstaticr and qhullr
remove libqhull, libqhullp, libqhullr to avoid double searches
remove all but testqset from testqset
Replace all include files with _r.h
[qhull_all] Remove all spaces before the parens 'qh_... (...)'
[qhull_all] Change copyright to 2014
Checked in source

Removed rboxT from rboxlib_r.c
1138 errors and 438 warnings.
Remove dependency on libqhull_r for statT
Convert FOREACHsetelement_i_ in libqhull_r.h
traceN needs qh for qh_fprintf
add qh to () calls
Down to 600 errors
