Common rpmlint warnings and errors

Some rpmlint warnings and errors are generated by MinGW packages. This page explains what they mean and whether they can be ignored. Also details of long-term plans to get them fixed.

In general we hope that some future version of rpmlint will be released that allows us to ignore certain warnings for MinGW packages.

devel-file-in-non-devel-package

All MinGW packages are for development only, so when we passed the guidelines we didn't opt to have a separate -devel subpackage, since the main package would just be empty. See bug 468987.

script-without-shebang [some .la file]

We use *.la files when linking. This is explicitly allowed in the MinGW guidelines that were passed.

Longer term we would like to check whether *.la files are genuinely necessary, and whether we can remove them.

spurious-executable-perm

See this comment for a detailed explanation.

arch-independent-package-contains-binary-or-object

See bug 468989.

non-standard-dir-in-usr i686-pc-mingw32

This breaks the FHS, but is permitted by the MinGW guidelines. These directories in /usr are ugly, but are commonly used by cross-compilation tools. The FHS project upstream is dead, so we can't get the directory added to the standard. It is thought to be very complex to remove the need for this directory from gcc and binutils.

file-not-in-%lang

This is a real error. You can use %find_lang with MinGW packages, although the exact usage isn't that obvious. Use it like this:

Name: mingw32-foo

%install

%find_lang foo

%files -f foo.lang
