GDAL 1.2.0a - Build problem w/ libtiff on AIX 4.3.3

[Daniel Morissette]

Starting a new build og GDAL 1.2.0a on AIX 4.3.3 w/ GCC 3.3.2

I ran into the following error with the internal libtiff:

OK, I see in tiff.h that this is a known issue: #39

Frank, would you like access to our AIX box to test this?

[warmerdam]

In the short term, the work around is to edit gdal/frmts/gtiff/libtiff/tiff.h
and remove the check for USING_VISUALAGE.

Change this:

#if defined(_H_INTTYPES) && defined(_ALL_SOURCE) && defined(USING_VISUALAGE)

To this:
#if defined(_H_INTTYPES) && defined(_ALL_SOURCE)

[warmerdam]

I take that last comment back .. still investigating. 

[warmerdam]

After a small adjustment to gtiff/tif_ovrcache.cpp, and the above mentioned
modification, things seems to compile fine on AIX. 
The change to tif_ovrcache.cpp has been committed.  The other change has not,
since it presumably would break things in other circumstances. 

[warmerdam]

Note, a 1.2.0a5 release has been prepared that should work out of the box 
for --without-libtool builds on AIX ... with the exception of still needing
to manually patch gdal/frmts/gtiff/libtiff/tiff.h.

I was going to try building MapServer to verify it works but I gave up 
when I realized I would need to build GD too. 

The following line does build a proper gdalinfo executable though:

g++ `gdal-config --cflags` gdalinfo.c `gdal-config --libs` -o gdalinfo

Thanks Frank.  I'll give this a try this afternoon... and once GDAL is built
then my next target is MapServer, so we'll know soon enough if MapServer does build.

BTW, a static build is fine for me.  That's what most libraries seem to do
anyway on this platform.

[Daniel Morissette]

I just wanted to confirm that the static build (--without-libtool) worked fine
*after patching tiff.h* and I was also able to produce maps using MapServer
reading a TIFF layer through GDAL. 
My config options were:
./configure --without-libtool --prefix=/opt/mapserver --with-png=/opt/mapserver
--with-libz=/opt/mapserver --with-jpeg=/opt/mapserver --with-odbc=/opt/mapserver
