[Radiance-general] Compiling rad4Rall on W7 64 bit Cygwin

[Claus Brøndgaard Madsen]

Hi Mark,
I ”resolved” the sighandler issue by applying the fix I found at:
http://www.radiance-online.org/pipermail/radiance-dev/2006-February/000676.html
Quoting:
I came across this problem when compiling Radiance under Interix.  I
resolved it by commenting out these three lines near the top of the file
persist.c:

typedef void (sighandler_t)(int);
static sighandler_t sig_io;
static sighandler_t sig_alrm;

I should warn you that I didn't look into the problem too deeply, so
that may or may not be the best solution!

Doing exactly “as I was told” I arrived at error free compilation, and I have had no problems running RADIANCE programs since.

Best,
Claus

Radiance group,

I tried to compile rad4Rall on a Windows 7 64 Bit Cygwin system. After making this change to ezxml.h: http://luminance.londonmet.ac.uk/radiance_mailinglists/general/2010-October/007397.html it compiled but with errors.

The first error I could find was:

persist.c:42: error: conflicting types for ‘sighandler_t’
/usr/include/signal.h:11: error: previous declaration of ‘sighandler_t’ was here
make: *** [persist.o] Error 1

Same as Claus had here http://luminance.londonmet.ac.uk/radiance_mailinglists/general/2010-October/007402.html

Was there ever a resolution?

As a fix, would it be reasonable to merge a full set of Cygwin Radiance 3R7 bin and lib files with a partial set of 4.0 files, and just keep the 4.0 files where duplicates occur? Looks like the non-duplicates were lookamb, rpict, rtrace, rview, and rvu. Also, rayinit.cal and glazing.cal were not in the lib directory. Although, these are some pretty major files not to have compile, I just ran oconv and rpict on an old project and it seemed to work fine.

Thanks for any help.

Mark de la Fuente
