Package: libpng12-dev
Version: 1.2.49-1
Severity: normal
I use libpng in my C++ program. This works fine.
However when compiling in C++11 mode, with a very recent version of
gcc, I get the following warning when compiling:
CXX image-png.o
In file included from image-png.h:18:0,
from image-png.cc:15:
/usr/include/libpng12/png.h:2659:31: warning: invalid suffix on literal; C++11
requires a space between literal and identifier [-Wliteral-suffix]
fprintf(PNG_DEBUG_FILE,"%s"m PNG_STRING_NEWLINE,(num_tabs==1 ? "\t" :
^
/usr/include/libpng12/png.h:2667:31: warning: invalid suffix on literal; C++11
requires a space between literal and identifier [-Wliteral-suffix]
fprintf(PNG_DEBUG_FILE,"%s"m PNG_STRING_NEWLINE,(num_tabs==1 ? "\t" :
^
/usr/include/libpng12/png.h:2675:31: warning: invalid suffix on literal; C++11
requires a space between literal and identifier [-Wliteral-suffix]
fprintf(PNG_DEBUG_FILE,"%s"m PNG_STRING_NEWLINE,(num_tabs==1 ? "\t" :
^
In practice this still works as intended (modulo the warning), but as
I understand it, it's not guaranteed that it will.
Luckily, the fix is very simple and safe: Add a space between the
string ("%s") and "m".
Thanks,
