A program can run on puppy4, but it can’t run on puppy3

[ch19860304]

I write a program based on sdl_mixer library, this program is used play audio file. I debug and complie it on suse10, and link to sdl_mixer and sdl static library,.
Then I put this program at puppy4 , It can play audio file normally。But when I put it on puppy3, It can’t play audio file, and it display message “unable to load WAV file!

hmmm well if you're smart enough to write compile and debug a program, i guess you're smart enough a) to check that the wav fileyou're trying to play actually exists b) give us sufficient information about your two setups that will help someone resolve your problem

Or c) compile it with debug enabled and use gdb...

Strange; I first learned wavrec and wavplay on 3.01

If you just try running it from a console, in pup3, it should give an error message that can give you some clues.

a)I pretty sure wav file I want play is really exist!
b)the vesion of my puppy3 is puppy 3.01, the vesion of my puppy4 is 4.1.2

the program can still running! it just can't make voice, the message is as followed:

as for .mp3 and .mod file
call Mix_LoadMUS failed: Module format not recognized

as for .wav file
call Mix_LoadMUS failed: Unable to load WAV file

if you are using sound programs the dependencies and libraries can be different between 3 and 4. for example i have the xmms.pet for 3 and 4 and have install both in 3 with no problem but i had to use 3 in 4.21 and it sounded like my speakers were blown out. uninstalled and found the 4 pet , beautiful.

check the dependencies list at the repo on puppylinux.ca/puppyfiles.

the main difference between 3 and 4 is gtk and other minor changes.

Try running, on puppy 4, ldd the_name_of_your_binary_program, then do the same on puppy 3, and compare the 2 outputs. A lot of libraries are different between the 2 versions.
