Description Duncan Hill 2005-03-11 06:24:17 UTC

Attempting to build 2.2.0 (not yet an ebuild) on Gentoo encounters issues with the tail statements in all of the Makefile.in files.   Gentoo uses the newer version of tail that has deprecated (to the point of no support) the tail +2 syntax in favour of tail -n +2.  Wietse has said the distro will not change because it can and will break non-POSIX capable systems.

Reproducible: Always
Steps to Reproduce:
1. download postfix source
2. execute make
3.

Actual Results:  
Postfix will fail to compile 


Potential fixes:  
1)  
for file in `find . -name 'Makefile.in'` ; do cat $file | sed -e 's/tail \   
+2/tail -n +2/' > $file.t ; mv $file.t $file ; done  
  
2)  
# Cater for GNU coreutils "compatibility"  
_POSIX2_VERSION=199209  
export _POSIX2_VERSION  
  
Edition 2 forces tail to honour the non-POSIX syntax.  
 
I realise 2.2.0 is not yet into the portage tree as a package, but felt that 
it was worth giving someone a heads-up just in case.

the ebuild takes care of that.
