Hello !
Good :
With the latest Update to SDL_image i don’t need
to add any extra flags. Before that i always had to add
-I/usr/local/include
Bad :
With the latest Update to SDL_mixer the detection for the C++
Compiler was removed and so i get an new, delete … undefined message
with CYGWIN ( MinGW Mode ). SMPEG is also installed. One way is to
add -lstdc++ or to use c++ again.
CU
Neither of these are caused by SDL, but are the result of your compiler
environment and/or the packager of your SDL binaries (presumably the
Cygwin developers).On Thu, 2007-07-19 at 09:43 +0200, Torsten Giebl wrote:

They are not. I installed libjpeg from the gnuwin32 site
and installed it in /usr/local/…, which is a pretty standard
location. I also changed all the paths in it so that the paths are correct.
I think that the gcc MinGW behaviour not compiling C++ is pretty
standard with gcc. You then have to use g++.

Glad to hear.

This should be fixed in subversion. Can you check it out?
Thanks!

In seven hours or so, just sitting at work.

You changed SDL_image not SDL_mixer :

You changed SDL_image not SDL_mixer :
Whoops! Okay, try now.
See ya,

This does not fix it. The same error message

Hello !
I know nothing about Autoconf, but is adding
the Test for the C++ Compiler enough.
I mean don’t you have to say with some rules
or so that instead using gcc it should use g++
for .cpp files ?
In the evening i will test which last version of SDL_mixer
worked. An easier fix would be adding -lstdc++ to the link flags
or the static version, if there is one. Any reason against this solution ?

Well, yes, you should use AC_PROG_CXX in the configure script for your
application project, if there is C++ code in it.

for .cpp files ?
I think that is what that macro does, among other things, apart from
checking for the existence of some usable C++ compiler.

You mean when building the SDL_mixer lib…? That would pull in
libstdc++ even for applications not using it. (C applications don’t,
and C++ applications don’t have to, although most do.) It would
probably work, but it just doesn’t seem right…

But is there not always going C++ stuff in there,
when you use g++ or when you use stdc++, as it is a .cpp
file with classes.
Another way would be to completely
throw smpeg compilation out of SDL_mixer.
In SMPEG you find something like :
There is no longer explicit support for the SDL_mixer library.
You can have the SDL mixer library mix audio from a movie by hooking into
the SDL mixer music hooks:
The hooks named above would still provide ways
to use SMPEG with SDL_mixer.
