Hello All,
As I wrote a few minutes ago, I am attempting to build PDFedit v 0.4.5 on
CentOS 5, using the distro's provided GCC 4.1.2 toolchain. The method
CPageContents::addInlineImage() is giving me some trouble, the bulk of which I
raised in my previous mail. In addition, however, I see some worrisome
warnings in the same method:
g++ -c -g -O2 -fmessage-length=0 -D_FORTIFY_SOURCE=2 -fno-strict-aliasing
-fexceptions -fstack-protector -pipe -posix -ansi -std=c++98 -pedantic -I.
-I/home/jbolling/rpm/BUILD/pdfedit-0.4.5/src
-I/home/jbolling/rpm/BUILD/pdfedit-0.4.5/src/xpdf/ -I/usr/include
-I/usr/include/freetype2 -I/usr/include -o cpagecontents.o cpagecontents.cc
cpagecontents.cc: In member function 'void
pdfobjects::CPageContents::addInlineImage(const std::vector<char,
std::allocator<char> >&, const libs::Point&, const libs::Point&)':
cpagecontents.cc:543: warning: passing 'const double' for argument 1 to
'pdfobjects::CObjectSimple<Tp>::CObjectSimple(const typename
pdfobjects::PropertyTraitSimple<Tp>::value&) [with pdfobjects::PropertyType Tp
= pInt]'
[...]
cpagecontents.cc:544: warning: passing 'const double' for argument 1 to
'pdfobjects::CObjectSimple<Tp>::CObjectSimple(const typename
pdfobjects::PropertyTraitSimple<Tp>::value&) [with pdfobjects::PropertyType Tp
= pInt]'
These arise from the following two lines of code:
image_dict.addProperty ("W", CInt (image_size.x));
image_dict.addProperty ("H", CInt (image_size.y));
Evidently, image_size.x and image_size.y are of type (const double), but they
are passed to a constructor expecting an int&. I'm neither sure what is
needed, nor sure what actually happens here (and that in itself is a minor
problem). Given that we're dealing with references, however, I can't think of
an approach the compiler could take to the issue that would be likely to have a
satisfactory result.
The most obvious fix would be to change the CInts to CReals, but I don't know
whether that would cause trouble elsewhere in the program.
Best,
John Bollinger
