=== DEV300_m106/vcl/source/fontsubset/list.c has the following line
#include <stdlib.h>

=== DEV300_m106/stlport/unxsoli4/misc/build/STLport-4.0 produces header files 
whose file name collides with the ones in /usr/include 

$ f=`ls /wb/ooo/build/local/DEV300/DEV300_m106/solver/300/unxsoli4/inc/stl`
$ (cd /usr/include; ls -1 $f) 2>/dev/null

=== Conclusion
The line #include <stdlib.h> in list.c seems to mistakenly includes 
$OUTDIR/inc/stl/stdlib.h, instead of /usr/include/stdlib.h

A header file of STLport-4.0 tries to obtain a type of complier by looking 
for a macro "__SUNPRO_CC" predefined by Sun C++ compiler, but fails 
because the Sun C compiler does not predefine it, but "__SUNPRO_C."
Consequently, #error "Your compiler version is not recognized by STLport. 
Please edit <config/stl_mycomp.h>" occurs.

Workaround (it seems okay with compilation):

and apply the same deletion to other *.mk files in the top of vcl directory.

Comment 4 philipp.lohmann 2011-04-13 15:11:47 UTC
I favor not using stdlib.h instead, replacing malloc/free by sal's allocator instead (rtl_allocateMemorym/rtl_freeMemory). Removing the include path to or stl could potentially produce other problems depending on whether there are stl headers on the system or not; we could end up with using mixed headers then.

Fixed in CWS ooo340fixes
Comment 5 philipp.lohmann 2011-04-13 15:16:44 UTC
since I don't have a system around to check that properly (on my solaris box this compiled without any patch), could you please check whether that solves your problem ? patch is here:
Comment 6 tora3 2011-04-13 18:46:15 UTC
pl: thank you for your fix.

Here is a result. 
In sum, vcl/source/fontsubset/list.c becomes innocent.
solver/300/unxsoli4/inc/sal/config.h has #include <stdlib.h>

extern "C"
	#include "stdio.h"
	#include "jpeg.h"
	#include "jpeglib.h"

It seems that those stdio.h are treated as $OUTDIR/inc/stl/stdio.h, 
instead of /usr/include/stdio.h

I don't know how it affects. Is it harmful? 
Maybe no, but somewhat against what a programmer expects.

It seems that $OUTDIR/inc/stl/stdio.h does some settings for itself first, 
then internally includes /usr/include/stdio.h

# if (__SUNPRO_CC < 0x530)
# if (__SUNPRO_CC < 0x600 || ((__SUNPRO_CC | 0x0FFF) > 0x0FFF && __SUNPRO_CC < 0x6000))
#      if ( __SUNPRO_CC < 0x401 )
#      endif

There is a patch for the file. 
It is stlport/STLport-4.0-sunstudio12u1.patch

vcl/source/fontsubset/list.c is in C, so C compiler is invoked.
The C compiler of SunStudio defines __SUNPRO_C, instead of __SUNPRO_CC.
Thus, stl_sunpro.h fails detection of compiler version.
Consequently, the macro __GIVE_UP_WITH_STL is called, which leads #error.

How and what shall we do?
Comment 9 philipp.lohmann 2011-04-14 09:15:43 UTC
Oops. Thanks for testing that.

The stl replacements for the std c headers are AFAIK purely to pl tricks with the namespace, the functionality is not changed. The reason I want to keep the $(OUTDIR)/inc/stl include is for the real stl headers like hash_map and so on; I think we should not mix these with possible system installed ones.

So this leaves list.c, which breaks because of the compiler define; we could either define the "missing" __SUNPRO_CC or convert the .c file to .cxx which would cause it to be compiled with the proper c++ compiler. I tried the latter and it can be done easily by replacing the use of "this" (which is a valid c variable) by "pThis" which then compiles as c++.

What's your opinion ?
Comment 10 philipp.lohmann 2011-04-15 11:20:24 UTC
done so in CWS ooo340fixes; list.c is now list.cxx which should solve the problem.

pl: cws/ooo340fixes/rev/4bb22962a758 works well with SunStudio on OpenSolaris x86.
Thank you for your efforts.
Comment 12 Oliver-Rainer Wittmann 2012-06-13 12:26:39 UTC
getting rid of value "enhancement" for field "severity".
For enhancement the field "issue type" shall be used.
