# Reporting Bugs in libsndfile

Before even attempting to report a bug in libsndfile please make sure you have read the Frequently Asked Questions. If you are having a problem writing code using libsndfile make sure you read the Application Programming Interface documentation.

That said, I am interested in finding and fixing all genuine bugs in libsndfile. Bugs I want to fix include any of the following problems (and probably others) :

- Compilation problems on new platforms.
- Errors being detected during the `make check' process.
- Segmentation faults occuring inside libsndfile.
- libsndfile hanging when opening a file.
- Supported sound file types being incorrectly read or written.
- Omissions, errors or spelling mistakes in the documentation.

When submitting a bug report you must include :

- Your system (CPU and memory size should be enough).
- The operating system you are using.
- Whether you are using a package provided by your distribution or you compiled it youself.
- If you compiled it yourself, the compiler you are using. (Also make sure to run "make check".)
- A description of the problem.
- Information generated by the sndfile-info program (see next paragraph).
- If you are having problems with sndfile-play and ALSA on Linux, I will need information about your kernel, ALSA version, compiler version, whether you compiled the kernel/ALSA your self or installed from a package etc.

If libsndfile compiles and installs correctly but has difficulty reading a particular file or type of file you should run the sndfile-info program (from the examples directory of the libsndfile distribution) on the file. See here for an example of the use of the sndfile-info program.

Please do not send me a sound file which fails to open under libsndfile unless I specifically ask you to. The above information should usually suffice for most problems.

Once you have the above information you should email it to one of the mailing lists (posting to these lists is limited to the list subscribers).
