[Buildroot] changing sources before patching

[Buildroot] changing sources before patching

[Alexander Dahl]

Hei hei,

in the fli4l [1] project, we use buildroot as build system, a little
custom stuff on top, but basically it's buildroot. Now Carsten wanted to
make a package for sfftools [2], especially sfftobmp3. The source is
only available from subversion and we need to patch it. The problem we
face is: some files we need to patch (e.g. configure.ac) have CRLF aka
DOS line endings and patch fails then. So we want to convert the line
endings to LF aka unix before patching. Is this possible with buildroot
and how? Or does anyone else has a good idea for an elegant solution to
this problem?

(please keep Carsten and Christoph in Cc)

Hi Alexander,

patching a package where source files contain CRLF is possible with
buildroot, the patch file has to contain CRLF as well, for example see
https://git.busybox.net/buildroot/tree/package/transmission/0001-fix-utypes
.patch 

Regards, Bernd

  As Bernt wrote, you can have a patch containing the correct CRLF.

  Alternatively, you can run a conversion in the _PRE_PATCH_HOOKS.
