When runnig rpmbuild with command
rpmbuild -v -ba --sign --clean ~/rpmbuild/SPECS/myspecfile.spec
I get this output:
Enter pass phrase:
Pass phrase is good.
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.6akVI6

+ $'\r'
**: command not foundwXWF: line 30:**
error: Bad exit status from /var/tmp/rpm-tmp.6akVI6 (%prep)
So I edited the temporary file /var/tmp/rpm-tmp.6akVI6, searched line 30, and found a single character there:
^M
If I execute the temporary file I get the same error, but it executes the all lines after 30, unlike the rpmbuild that breaks on that line and doesn't continue executing:
sudo sh /var/tmp/rpm-tmp.6akVI6
+ umask 022
+ cd /home/rpmbuilder/rpmbuild/BUILD
+ LANG=C
+ export LANG
+ unset DISPLAY
+ $'\r'

+ cd mysource-1.0.0
+ /bin/chmod -Rf a+rX,u+w,g-w,o-w .
+ exit 0
If I edit the file and remove line 30 (^M) I am able to run the script with no errors:
sudo sh /var/tmp/rpm-tmp.6akVI6
+ umask 022
+ cd /home/rpmbuilder/rpmbuild/BUILD
+ LANG=C
+ export LANG

+ '[' 0 -ne 0 ']'
+ cd mysource-1.0.0
+ /bin/chmod -Rf a+rX,u+w,g-w,o-w .
+ exit 0
This suggests me that the rpmbuild is being stopped because of that single character on line 30.
Any hints why is this happening?
Found the answer in here
It seems that files saved on windows, get that character, it is a DOS line ending.
I had my spec file created on windows, so I edited it and did the suggested commands:
:set fileformat=unix
and re-ran rpmbuild and it worked.

I've written a lot of Bash, but I now need to port some of my code into /bin/sh, and I'm observing strange behavior.
I have a function:
path_exists() {
path="$1" && shift
echo "$PATH" | tr ':' '\n' | while read path_entry ; do
test "$path" = "$path_entry" && return 0
done
return 1
}
I'm calling it like so:
if path_exists "/usr/bin" ; then
echo "it exists"
else
echo "it does not exist"
fi
If I run it with set -x, I see that return codes are overwritten:
+ path_exists /usr/bin
+ path=/usr/bin
+ shift
+ echo /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin
+ tr : \n
+ read path_entry
+ test /usr/bin = /usr/local/sbin
+ read path_entry
+ test /usr/bin = /usr/local/bin
+ read path_entry
+ test /usr/bin = /usr/sbin
+ read path_entry
+ test /usr/bin = /usr/bin
+ return 0
+ return 1
+ echo it does not exist
Why is my function not respecting my return codes?
Why is my function not respecting my return codes?
Because pipe spawns a subshell, and you are only returning from a subshell. The same way:
echo | exit 0
will not exit your shell, only exit from | { the subshell on the right side of pipe; }. Or the same way func() { ( return 1; echo 123; ); return 0; }; func - the return 1 only affects the subshell.
The behavior is the same in ash, dash and in bash, but I think in POSIX sh it would be unspecified.
Aaaaanyway:
path_exists() {
case ":$PATH:" in
*:"$1":*) ;;
*) false; ;;
esac
}
I would like to list all files that bitbake will fetch when I bake an image.
Currently, I am able to get the SRC_URI of all files needed to bake a Yocto image by executing bitbake core-image-minimal -c fetchall and then parse log files.
Is there is a simpler way to get the same result without the need to download files ?
I am not sure bitbake supports such feature. Ideally, I am looking for a command that prints out the package name and lists all files with corresponding URL
> bitbake core-image-minimal -c fetchall --print-only
Generally bitbake doesn't provides such functionality.
But I was able to create a simple solution witch creating simple .bbclass file which is inherited in all recipes, by adding it into local.conf file, please see my steps in order to archive that:
Steps:
let's create a class print-src.bbclass file used to get and print SRC_URI variable (remember to store this class file in layer which is available in conf/bblayers.conf):
$ cat print-src.bbclass
python do_print_src () {
# should probably be indented
srcuri = d.getVar('SRC_URI', True).split()
bb.warn("SRC_URI look like: %s" % srcuri)
}
addtask do_print_src before do_fetch
Add INHERIT += "print-src" into Your conf/local.conf file
Edit: it is important to use bitbake --runonly option, that allows to run specific task of the taskgraph for the specified target (with --runonly option do_print_src needs to be used as print_src),
Edit: Please note that --runall=RUNALL and --runonly=RUNONLY was introduced with Yocto Sumo release 2.5,
$ bitbake core-image-minimal --runonly print_src

This is not an optimal solution but I hope that such feature gets its way to mainline stream.
I needed something like this and got part way there before now.
I can generate a messy list of URIs used by executing the following command:
bitbake -g zlib && cat recipe-depends.dot | \
grep -v -e '-native' | grep -v digraph | \
grep -v -e '-image' | awk '{print $1}' | \
sort | uniq | xargs -I {} -t bitbake -e {} | grep SRC_URI=
This gives you all the URIs and files used in a recipe and some comments.
Not a perfect solution but I will see if I can improve on it.
A bit manual and straight forward way is to build your image from scratch, and copy all the fetch logs, and go thru it.
$ mkdir fetch_logs
$ find tmp/work/ -type f -name log.do_fetch* | cpio -pdm fetch_logs
Now grep "Fetch(ing/er)" in this fetch_logs and it will provide info on which URL your recipe used to fetch the source. This will be helpful to see the final URI used to fetch in PREMIRROR based builds.
NOTE: if you have sstate-cache enabled and functional, you may not see do_fetch at all.
I wrote scripts based on the solution in the question.
Basically I need to make a cscope project of all the sources, and hence I need to list all URI and clone all repos.
I wrote 2 scripts 1) List all SRC_URI and Branches
2) Install(clone) all the code in a single directory

I would like to execute two commands in a row independent of the failure or success of the previous one, so I know that || and && will not work. What can I do in this case? I would like to have the shell wait for the first command to finish if it is successful; hence ; does not work either.
EDIT: I apologize the shell would be zsh and I run a shell script sending commands to different screens as seen below:
#! /bin/zsh
### Script for running everything in screens ###
### System argument screen name suffix ###

done
return 0
Use | or & instead of usng || or &&
for zsh, especially on a mac, it's ;
try it from the terminal

There will be a 3 seconds delay then it will print hello
I want to run perltidy before i look for diff in my subversion working copy.
in svn config i wrote:
diff-cmd = /usr/bin/d.sh
As David W said in this answer https://stackoverflow.com/a/5834900/1927848 i make a script /usr/bin/d.sh:
#!/usr/local/bin/bash
/usr/local/bin/perltidy "$1" > "/tmp/$1"
/usr/local/bin/perltidy "$2" > "/tmp/$2"
/usr/bin/diff "$1" "$2"
/bin/rm "/tmp/$1" "/tmp/$2"
exit 0
and when i make svn diff in working copy i got some errors:
dev# svn diff
Index: nodeny/new_month.pl
===================================================================
Unknown option: u
Error on command line; for help try 'perltidy -h'
Option l is ambiguous (libpods, line-up-parentheses, logfile, logfile-gap, long-block-line-count, look-for-autoloader, look-for-hash-bang, look-for-selfloader)
Error on command line; for help try 'perltidy -h'
diff: option requires an argument -- L
/usr/bin/diff: Try `/usr/bin/diff --help' for more information.
where is my errors?
UPD: $1 and $2 are not file names, $6 and $7 contains file names. i made some modifications to code, thanks to ikegami comment
#!/usr/local/bin/bash
/usr/local/bin/perltidy "$6" -st > "/tmp/tidy001"
/usr/local/bin/perltidy "$7" -st > "/tmp/tidy002"
/usr/bin/diff "/tmp/tidy001" "/tmp/tidy002"
/bin/rm "/tmp/tidy001" "/tmp/tidy002"
exit 0
but now script only does first perltidy command and wait... whats wrong?
UPD2: perl script, that works:
#!/usr/bin/perl
use Text::Diff;
if (-e $ARGV[-2] && -e $ARGV[-1]) {
my $str1 = `/usr/local/bin/perltidy -npro -pbp -nst -se -et=4 -bar -l=200 $ARGV[-2] -st`;
my $str2 = `/usr/local/bin/perltidy -npro -pbp -nst -se -et=4 -bar -l=200 $ARGV[-1] -st`;
my $diff = diff(\$str1, \$str2);
print $diff;
}
else {
print "Error file $ARGV[-2] or $ARGV[-1] not exists\n";
}
exit 0;
I'm not an experienced bash code, so the following may not be optimal, especially given the redundancy, but it solves your problem by assuming the last two args are the file names.
#!/bin/bash
args=("$#")
f1_idx=$(( ${#args[#]} - 2 ))
f1="${args[$f1_idx]}"
/usr/local/bin/perltidy "$f1" -st > "/tmp/$f1"
args[$f1_idx]="/tmp/$f1"
f2_idx=$(( ${#args[#]} - 1 ))
f2="${args[$f2_idx]}"
/usr/local/bin/perltidy "$f2" -st > "/tmp/$f2"
args[$f2_idx]="/tmp/$f2"
/usr/bin/diff "$args[#]"
/bin/rm "/tmp/$f1" "/tmp/$f2"
exit 0
Or if you don't care about the actual file names (as your update implies), you can avoid the temporary files altogether.
#!/bin/bash
args=("$#")
last_idx=$(( ${#args[#]} - 1 ))
f2="${args[$last_idx]}"
unset args[$last_idx]
last_idx=$(( ${#args[#]} - 1 ))
f1="${args[$last_idx]}"
unset args[$last_idx]
/usr/bin/diff "$args[#]" \
<( /usr/local/bin/perltidy "$f1" -st ) \
<( /usr/local/bin/perltidy "$f2" -st )
exit 0
I am curious about what happens under the hood of the mkvirtualenv command and so I am trying to understand how it calls virtualenv.
The lowest hanging fruit is to figure where the virtualenv program is located after installation and where the mkvirtualenv program is located after installation. So:-
Calvins-MacBook-Pro.local ttys006 Mon Apr 23 12:31:07 |~|
calvin$ which mkvirtualenv
Calvins-MacBook-Pro.local ttys006 Mon Apr 23 12:31:10 |~|
calvin$ which virtualenv
/opt/local/library/Frameworks/Python.framework/Versions/2.7/bin/virtualenv
So the strange thing I see here is that which mkvirtualenv does not give any result. Why?
Digging further, in the virtualenvwrapper directory after installing it, I see only 3 python files:-
Calvins-MacBook-Pro.local ttys004 Mon Apr 23 12:28:05 |/opt/local/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/virtualenvwrapper|

-rw-r--r-- 1 root wheel 11472 Apr 13 15:07 user_scripts.pyc
And I suppose that the only reason why mkvirtualenv is now available in my terminal is because I have added in a source/opt/local/library/Frameworks/Python.framework/Versions/2.7/bin/virtualenvwrapper.sh. So answering the question I asked earlier, this is simply because mkvirtualenv is expressed as a bash function and is available in my terminal because I have sourced virtualenvwrapper.sh in my .bashrc or .bash_profile files.
Digging into the virtualenvwrapper.sh script, I see
# Create a new environment, in the WORKON_HOME.

Here's where I don't understand yet - I don't seem to see any direct reference to virtualenv in this bash function. So how exactly does this bash function mkvirtualenv pass the arguments from command line (e.g. mkvirtualenv -p python2.7 --no-site-packages mynewproject) to the python virtualenv program?
So this is the line that does the trick.
(
[ -n "$ZSH_VERSION" ] && setopt SH_WORD_SPLIT
\cd "$WORKON_HOME" &&
"$VIRTUALENVWRAPPER_VIRTUALENV" $VIRTUALENVWRAPPER_VIRTUALENV_ARGS "$#" &&
[ -d "$WORKON_HOME/$envname" ] && \
virtualenvwrapper_run_hook "pre_mkvirtualenv" "$envname"
)
$VIRTUALENVWRAPPER_VIRTUALENV is in fact the location of where the current virtualenv program resides.
