# NASM - The Netwide Assembler

version 2.15.01

## Appendix E: Contact Information

### E.1 Website

NASM has a website at `http://www.nasm.us/`.

New releases, release candidates, and daily development snapshots of NASM are available from the official web site in source form as well as binaries for a number of common platforms.

#### E.1.1 User Forums

Users of NASM may find the Forums on the website useful. These are, however, not frequented much by the developers of NASM, so they are not suitable for reporting bugs.

#### E.1.2 Development Community

The development of NASM is coordinated primarily though the `nasm-devel` mailing list. If you wish to participate in development of NASM, please join this mailing list. Subscription links and archives of past posts are available on the website.

### E.2 Reporting Bugs

To report bugs in NASM, please use the bug tracker at `http://www.nasm.us/` (click on "Bug Tracker"), or if that fails then through one of the contacts in section E.1.

Please read section 2.2 first, and don't report the bug if it's listed in there as a deliberate feature. (If you think the feature is badly thought out, feel free to send us reasons why you think it should be changed, but don't just send us mail saying `This is a bug' if the documentation says we did it on purpose.) Then read section 13.1, and don't bother reporting the bug if it's listed there.

If you do report a bug, please make sure your bug report includes the following information:

- What operating system you're running NASM under. Linux, FreeBSD, NetBSD, MacOS X, Win16, Win32, Win64, MS-DOS, OS/2, VMS, whatever.

- If you compiled your own executable from a source archive, compiled your own executable from `git`, used the standard distribution binaries from the website, or got an executable from somewhere else (e.g. a Linux distribution.) If you were using a locally built executable, try to reproduce the problem using one of the standard binaries, as this will make it easier for us to reproduce your problem prior to fixing it.

- Which version of NASM you're using, and exactly how you invoked it. Give us the precise command line, and the contents of the `NASMENV` environment variable if any.

- Which versions of any supplementary programs you're using, and how you invoked them. If the problem only becomes visible at link time, tell us what linker you're using, what version of it you've got, and the exact linker command line. If the problem involves linking against object files generated by a compiler, tell us what compiler, what version, and what command line or options you used. (If you're compiling in an IDE, please try to reproduce the problem with the command-line version of the compiler.)

- If at all possible, send us a NASM source file which exhibits the problem. If this causes copyright problems (e.g. you can only reproduce the bug in restricted-distribution code) then bear in mind the following two points: firstly, we guarantee that any source code sent to us for the purposes of debugging NASM will be used only for the purposes of debugging NASM, and that we will delete all our copies of it as soon as we have found and fixed the bug or bugs in question; and secondly, we would prefer not to be mailed large chunks of code anyway. The smaller the file, the better. A three-line sample file that does nothing useful except demonstrate the problem is much easier to work with than a fully fledged ten-thousand-line program. (Of course, some errors do only crop up in large files, so this may not be possible.)

- A description of what the problem actually is. `It doesn't work' is not a helpful description! Please describe exactly what is happening that shouldn't be, or what isn't happening that should. Examples might be: `NASM generates an error message saying Line 3 for an error that's actually on Line 5'; `NASM generates an error message that I believe it shouldn't be generating at all'; `NASM fails to generate an error message that I believe it should be generating'; `the object file produced from this source code crashes my linker'; `the ninth byte of the output file is 66 and I think it should be 77 instead'.

- If you believe the output file from NASM to be faulty, send it to us. That allows us to determine whether our own copy of NASM generates the same file, or whether the problem is related to portability issues between our development platforms and yours. We can handle binary files mailed to us as MIME attachments, uuencoded, and even BinHex. Alternatively, we may be able to provide an FTP site you can upload the suspect files to; but mailing them is easier for us.

- Any other information or data files that might be helpful. If, for example, the problem involves NASM failing to generate an object file while TASM can generate an equivalent file without trouble, then send us both object files, so we can see what TASM is doing differently from us.
