Subject: flex: scan.l needs rebuild?

Date: Sun, 27 Jun 2004 19:35:08 +0200

Package: flex
Version: 2.5.31-26
Severity: important

The build fails on amd64 like this:
/usr/lib/bison.simple: In function `yyparse':
/usr/lib/bison.simple:285: warning: `yyval' might be used uninitialized in this
function
/bin/sh /usr/src/flex-2.5.31/missing --run flex   `test -f scan.l || echo './'`scan.l
/usr/src/flex-2.5.31/missing: line 46: flex: command not found
WARNING: `flex' is missing on your system.  You should only need it if
         you modified a `.l' file.  You may need the `Flex' package
         in order for those modifications to take effect.  You can get
         `Flex' from any GNU archive site.
sed '/^#/ s|\.c|scan.c|' .c >scan.c
sed: can't read .c: No such file or directory
make[3]: *** [scan.c] Error 2

The patch seems to modify both the scan.l file and scan.c file.
And I don't think the scan.c file actually has the changes from
scan.l file either.

I think this is doesn't show up on other arches because they might
think the time of the file is the same?

Because the .diff.gz patches both scan.c and (then) scan.l, scan.l will
always be newer than scan.c, and the build will fail for want of flex.

Touching scan.c in debian/rules would fix the problem.  Although that
would require that you manually create scan.c whenever scan.l really
changes.
