Bugzilla Bug 20777

emerge par fails. the following is the output from that command:

Calculating dependencies ...done!
>>> emerge (1 of 1) app-arch/par-1.1 to /
>>> md5 ;-) par-v1.1.tar.gz
>>> Unpacking source...
>>> Unpacking par-v1.1.tar.gz to /var/tmp/portage/par-1.1/work
sed: -e expression #1, char 87: Unterminated `s' command
>>> Source unpacked.
make: *** No targets.  Stop.
 
!!! ERROR: app-arch/par-1.1 failed.
!!! Function src_compile, Line 25, Exitcode 2
!!! (no error message)

as you can see, sed fails to substitute the CFLAGS in the orignal makefile due
to a bug in the ebuild. the ebuild uses double quotes in the sed command which
can cause problems. ideally, when specifing a script on the command line with
sed, single quotes should be used. modifiying the ebuild fixes this problem.

here is the output from 'emerge info':

there is only one version of par, par-1.1, and it is affected. i am currently
using sed ver. 4.0.7.

by going into /var/tmp/portage/par-1.1/work/par-cmdline and testing the sed
command from the ebuild seperately, the sed command no longer fails. previously,
it would output a blank 'Makefile' since sed bombed out with an error. this is
what causes 'emerge par' to report " make: *** No targets.  Stop."

Reproducible: Always
Steps to Reproduce:
1. emerge par
Actual Results:  
command failed with the error 

"!!! ERROR: app-arch/par-1.1 failed.
!!! Function src_compile, Line 25, Exitcode 2
!!! (no error message)"

Expected Results:  
should have emerged par

sed command line in /usr/portage/app-arch/par/par-1.1.ebuild should read as follows:
" sed 's/CFLAGS.*/CFLAGS = -Wall $CFLAGS/' Makefile.orig > Makefile"
instead of
"sed "s/CFLAGS.*/CFLAGS = -Wall $CFLAGS/" Makefile.orig > Makefile"

last minute note: this does not solve the problem. changing the above results in:

 Calculating dependencies ...done!
>>> emerge (1 of 1) app-arch/par-1.1 to /
>>> md5 ;-) par-v1.1.tar.gz
>>> Unpacking source...
>>> Unpacking par-v1.1.tar.gz to /var/tmp/portage/par-1.1/work

I thought I had fixed this for sure! It seems like sed does not interpret
$CFLAGS in its command line as a shell variable, and instead puts '$CFLAGS'
verbatim in the new output Makefile. So now running 'make' fails since gcc
thinks more than one input file is being used.

Hopefully more collaboration can fix this buggy ebuild. I'd really like to get
par to work!

fixed in cvs

compiles fine here

This works for me now. Please close this off completely.
