Post subject: conflict between ftstdlib.h (freetype-library) and pngconf.h
Archived from groups: comp>os>linux>development>apps (more info?)


Hi everybody,
I implemented freetype support in my application. Unfortunatelly I've got a
problem with these two files, which are included.

Both include-file try to includes setjmp.h. Because ftstdlib.h already
include setjmp.h I've got a compile error at the following line:
#include <png.h>

png.h includes pngconf.h which tries to include setjmp.h. I get following
error:
| /usr/include/pngconf.h:317: error: expected constructor, destructor, or
type conversion before "." token
| /usr/include/pngconf.h:318: error: "__dont__" does not name a type

If I look into pngconf.h:
| # ifdef __linux__
| # ifdef _BSD_SOURCE
| # define PNG_SAVE_BSD_SOURCE
| # undef _BSD_SOURCE
| # endif
| # ifdef _SETJMP_H
| /* If you encounter a compiler error here, see the explanation
| * near the end of INSTALL.
| */
| __png.h__ already includes setjmp.h;
| __dont__ include it again.;
| # endif
| # endif /* __linux__ */
|
| /* include setjmp.h for error handling */
| # include <setjmp.h>

Do anyone of you have a idea how to work around such problem? I read the
INSTALL file. There are two suggestion:
1. comment out following two lines:
| __png.h__ already includes setjmp.h;
| __dont__ include it again.;
2. use cexcept interface but I don't understand that.

Thank you!

Package: libpng2-dev
Version: N/A; reported 2000-02-01
Severity: important

I was trying to build the last ImageMagick (5.1.1) (It is not yet a debian package, you can get it at http://www.wizards.dupont.com/cristy/ImageMagick.html) and i had many errors about pngconf.h and png.h. Here are the firsts:

etc...

For the first error, i understand why: there are this strange lines in pngconf.h:

#ifdef _SETJMP_H
__png.h__ already includes setjmp.h
__dont__ include it again
#endif


Well this is weird.... It's obviously incorrect but I don't even guess
what the correct code could be

For the others errrors, i don't know


I tried with the debian packages installed, and then i tried with the
upstream tarball: all the same! So this should be fowarded upstream....

But now: how could anyone compile anything using libpng!?? (but
actually, it seems there was no packages depending on this lib in my
system)

This can't be of important severity, then.

First of all, this references /usr/local/include/. Debian packages don't put
any files in /usr/local, ever. But...

> #ifdef _SETJMP_H
> __png.h__ already includes setjmp.h
> __dont__ include it again

... this exists in our /usr/include/pngconf.h file, too.

The intention is actually quite clear (to me): you may not have any files
that #include setjmp.h file. Probably, that "png.c" file or any of the local
files it #include's does that, and it's apparently illegal.

Maybe it should have been marked with #error, that wouldn't print parse
errors but the exact message, but the point has been made, anyway.

Maintainer, please close this bug. Or correct me if I'm wrong <blush> :)

I don't think so!
(but as i'm not a debian developer and you are .....)

Let's me explain what i think about this:

ImageMagick 5.1.1 is not in Debian but libpng2-dev is, and i think
this is a libpng2-dev bug not an ImageMagic bug. And if ImageMagick is
still 4.8 in Debian it may be because the Maintener didn't succeded in
compiling 5.1.1 (du to this bug) ... maybe... anyway it seems that libmagick is only used by ImageMagick (at least for me)

... but i said that i've tried both the debian packages and upstream
tarball that i compiled myself. Both have the bug (so this is may be
an upstream bug)

This doesn't make any sense to me! Just a few line after this #ifdef
there is an #include <setjmp.h>. And AFAIK this is not a special
setjmp.h for libpng. ... This doesn't make sense at all ....


> Maybe it should have been marked with #error, that wouldn't print parse

Yes, at the very least, this should use #error, and this is what it
does in libpng0g-dev. But this is not my point ...

> Maintainer, please close this bug. Or correct me if I'm wrong <blush> :)

I'm not the Maintener but i still think you're wrong :-)

First there is a fix : just comment out the #ifdef .... #endif clause
in pngconf.h and it seems to works. At least i compiled ImageMagick
5.1.1 without any errors (and for the moment it runs fine). I don't
see any side effect that this fix could introduce.

And, Two, in the libpng doc (/usr/doc/libpng2-dev/libong.txt.gz) says
that pngconf.h is the place to do specific compiler configuration. So
let's say this is not a bug but a "configuration" that i would like to
see in the debian package!

FYI, the setjmp.h magic in pngconf.h is here because there are two
setjmp/longjmp on Linux depending or not you use BSD compatibility
(without BSD compatibility, setjmp/longjmp does not preserve the
signal mask, with BSD compatibility, they preserve and restore the
signal mask (you can get this behavior with sigsetjmp/siglongjmp if
you do not use BSD compat.)).

The struct jmpbuf they use are different and calling the BSD-longjmp
following a non-BSD setjmp will give strange results (like screwing up
the signal mask) and/or crash.

Since PNG uses setjmp/longjmp, they force the inclusion of longjmp.h and
force non-BSD mode.

Hence the header magic.

I replaced the syntactic error text with an #error directive and added
a comment explaining basically what I've tried to explain above.

For practical use, if you get the #error message, then moving <png.h>
before <longjmp.h> should make things work.

Phil.

Here are some tips that have been found helpful in compiling imal on some systems. For normal Unix systems, these steps should not be necessary.
  • In makefile, try substituting ``CC=g++'' for ``CC=gcc''.
  • If a problem occurs with xmtnimage16.cc, make sure libjpeg.a is somewhere on your system. In one case it was necessary to copy some of the libjpeg include files (jconfig.h, jdct.h, jerror.h, jinclude.h, jmemsys.h, jmorecfg.h, jpegint.h, jpeglib.h, and jversion.h) to the imal source directory or in /usr/include/gr.
  • Add /usr/X11R6/LessTif/Motif1.2/lib to /etc/ld.so.conf and type ``/sbin/ldconfig''. (This solved a problem on one machine that could not load libXm.so.1).
  • Check to make sure the files in /usr/X11R6/include/Xm are the correct version. Don't mix Motif 1.x files with 2.x libraries or vice versa.
  • If problems are encountered with calculator.l or calculator.y, try substituting bison and flex for yacc and lex respectively.
  • If you have an unusual CPU and the program compiles successfully but cannot read TIFF files, it may be caused by incorrect determination of the byte order. Each compiler seems to have a different way of indicating the byte order. Posix-compliant systems are supposed to have a file called bytesex.h or endian.h. If these files are not present, make may get the byte order wrong. To fix this, add either #define LITTLE_ENDIAN or #undef LITTLE_ENDIAN after the line #define MAXWINDOWS 10 in xmtnimage.h to force the correct byte order and run 'make clean' and 'make' again.
  • Don't edit y.tab.c or y.tab.cc. These are created automatically from calculator.y.

More compiling problems and solutions

  • Problem:
    In file included from xmtnimage.cc:11:
    xmtnimagec.h:9: Xbae/Matrix.h: No such file or directory
  • Solution:
    Xbae installation did not occur correctly. Manually copy libXbae.a to /usr/X11R6/lib and copy *.h to /usr/X11R6/include/Xbae.

  • Problem: grep: /Xm/Xm.h: No such file or directory
    ./configure: test: -ge: unary operator expected
  • Solution: Motif is not installed correctly; or paths to Motif are incorrect. This occurs on SuSE linux with Lesstif. Should say: found after looking for
    /usr/X11R6/include/Xm/Xm.h
    ...
    looking for /usr/openwin/share/include/Xm/Xm.h

  • Problem: In file included from xmtnimage.cc:10: xmtnimage.h:79: bytesex.h: No such file or directory
  • Solution:
    This should not occur. Delete config.cache and rerun ./configure.

  • Problem:
    gcc: installation problem, cannot exec `cc1plus': No such file or directory
  • Solution:
    gpp / g++ must be installed; egcs or gcc alone are not sufficient to compile C++ programs.

  • Problem:
    /usr/X11R6/lib/libXbae.a(Matrix.o)(.data+0xb7c):
    undefined reference to `XmeFromHorizontalPixels'
  • Solution: Motif is not installed correctly. This message will also occur during compilation of libXbae. Reinstall Motif and recompile and reinstall libXbae.a.

  • Problem:
    imal: loadlocale.c:220: _nl_load_locale: Assertion `idx % __alignof__ (u_int32_t) == 0' failed.
  • Solution: export LC_ALL=POSIX

  • Problem:
    /usr/local/include/pngconf.h:326: error: expected constructor,
    destructor, or type conversion before ?.? token /usr/local/include/pngconf.h:327: error: ?__dont__? does not name a type
  • Solution: Your libpng library is not installed correctly. Whenever you install libpng, it's necessary to delete lines 326 and 327 from pngconf.h. That is, the lines containing:
             __pngconf.h__ already includes setjmp.h;
    __dont__ include it again.;

Package: libpng12-dev
Version: 1.2.5.0-7
Severity: wishlist
Tags: patch

While compiling something today, I got the error:

In file included from /usr/include/png.h:332,
from xmtnimage65.cc:17:
/usr/include/pngconf.h:255: error: syntax error before `.' token
/usr/include/pngconf.h:256: error: parse error before `again'

Inside pngconf.h, there is some terse text on the reason for this.

After some googling, it turns out that libpng10-dev includes a much clearer
text. It also uses #error, instead of just causing a syntax error, and it
tells me how to solve the problem.

Could you please 'port' this to libpng12-dev? I've added a patch.
