[Radiance-general] Radiance on Windows 7 Ultimate using SUA (it works!)

I just wanted to tell that I've tried it and it works! (A bit to my
supprise.)

I have: Windows 7 Ultimate 64 bits.

I followed the guideline on the Radiance Wiki site:
./makeall install in ray folder
chosing ~/radiance/bin installs on Windows in C:\user\yourname\radiance\bin
I choose option 2) Linux (seems to be the best option).

I encountered three problems, here are they, with solution.

Problem 1: (Seems to be related to 64 bit system with 32 bit gcc and 64 bit
or wrong archiver)
This is the error:
Error code 127
AR_LIBRARIAN environment variable
===============================================================================
Solution:
Add: export PATH="/opt/gcc.4.2/bin:${PATH}" to
C:\windows\SUA\etc\profile.lcl
Also see: http://www.suacommunity.com/forum/tm.aspx?m=16624 for more
detailled info.


Problem 2:
Making programs...
/dev/fs/C/Windows/SUA/usr/examples/radiance/ray/src/common
/dev/fs/C/Windows/SUA
/usr/examples/radiance/ray/src
In directory common...
gcc -Dlinux -L/usr/X11R6/lib -L/usr/local/lib/x86 -L/usr/lib/x86
-L/usr/local/li
b/ray -I/usr/include/X11 -DNOSTEREO -O2 -c ezxml.c
ezxml.c: In function 'ezxml_parse_fd':
ezxml.c:647: error: '_SC_PAGESIZE' undeclared (first use in this function)
ezxml.c:647: error: (Each undeclared identifier is reported only once
ezxml.c:647: error: for each function it appears in.)
*** Error code 1 (continuing)
`install' not remade because of errors.
===============================================================================
Solution: Included: #define EZXML_NOMMAP in ezxml.c


Problem 3:
In directory rt...
gcc -I../common -L../lib -O2 -Dlinux -L/usr/X11R6/lib -L/usr/local/lib/x86
-L/us
r/lib/x86 -L/usr/local/lib/ray -I/usr/include/X11 -DNOSTEREO -o ./rtrace
rtmain.
o rtrace.o duphead.o persist.o ../lib/libraycalls.a ../lib/libradiance.a
-lrtrad
 -lm
../lib/librtrad.a(header.o):header.c:(.text+0x5b4): undefined reference to
`_tim
egm'
collect2: ld returned 1 exit status
*** Error code 1 (continuing)
===============================================================================
Solution: Included timegm.o in src/common/Rmakefile
Like:
UTLOBJ = ezxml.o ccolor.o ccyrgb.o bsdf.o bsdf_m.o bsdf_t.o loadbsdf.o \
 disk2square.o hilbert.o timegm.o

That's all, after that I ran gendaylit and Mark Stock's benchmark test
suite, and all works.

Still need to install an XServer (Xming) and a NFS server (included in
Windows 7 Ultimate).
And run some more tests including rvu, trad, falsecolor, rpiece.

I hope this is usefull,

Guy
