[Lcms-user] Problems getting 1.08 to run on Redhat 7.2

[Jim M. <jm...@ro...>]

Hi,

I just discovered LittleCMS and am having problems getting it to run on 
Redhat 7.2 Linux.  I looked through the "lcms-user" archives and didn't 
find anyone reporting similar problems, so I thought I'd describe what 
was going on before I dove into debugging mode.

I had no problems getting lcms-1.08 and lprof-1.08 to build.  I do, 
however, see the following problems:

(1) tifficc generally gets a segmentation fault.  When I poked around 
with gdb, I discovered that the fault is in the final call to 
"TIFFClose(out)" in "tifficc.c" file.  The actual fault is triggered 
int the malloc/free code.  The generated TIFF file is fine despite the 
error.

(2) When I run "qtmeasurementtool" and attempt to load a scanned 
target, I get an error message claiming that the TIFF file I'm loading 
a "null image".  Specifically, I get:


	QImage::smoothScale: Image is a null image
	QPixmap::convertFromImage: Cannot convert a null image
	QPixmap::convertFromImage: Cannot convert a null image

The image I'm attempting to load was generated using "xsane".  It 
displays fine with both the GIMP and ImageMagick.  I've done a "save 
as" from the GIMP with the same result.

At this point I'm rather suspicious that I've got problem or 
incompatibility with my TIFF library, and was wondering if other folks 
have seen similar problems.  Here are the versions of things I'm 
running:

lcms-1.08
lprof-1.08
TIFF: Redhat RPM libtiff-devel-3.5.5-13, libtiff-3.5.5-13
Qt: Redhat RPM qt-2.3.1-5
GCC: Redhat RPM gcc-2.96-98

I run the GNOME desktop, and use Sawfish as my window manager, though I 
don't see that that should be terribly relevant to the problems I'm 
seeing.

All the RPMs are off the Redhat 7.2 distribution.  The lcms and lprof 
files I downloaded from the http://littlecms.com web site.

Thanks.
