RPM build No such file or directory

Question

I want to create simple RPM file with many small files.

[root@laptop rpm]# tree
.
├── BUILD
├── BUILDROOT
├── RPMS
├── SOURCES
│   └── some_agent-1.0.tar.gz
├── SPECS
│   ├── kernel.spec
│   └── kernel.spec~
└── SRPMS

6 directories, 3 files
[root@laptop rpm]# 

I have this spec file:

Summary: some_agent
Name: some_agent
Version: 1.0
Release: 1
License: Apache
Group: application
Source0: %{name}-%{version}.tar.gz
BuildRoot: %{_tmppath}/%{name}-%{version}-%{release}-buildroot
%description
Test 

%prep
%setup -q

%build


%install
rm -rf $RPM_BUILD_ROOT
make root=$RPM_BUILD_ROOT install

%clean
rm -rf $RPM_BUILD_ROOT

%files
%defattr(-,root,root,-)
%doc
agent/*

But when I try to build the RPM package I get this error:

[root@laptop ~]$ rpmbuild -bb -v ~/rpm/SPECS/kernel.spec
Executing(%prep): /bin/sh -e /var/tmp/rpm-tmp.RUwFW5

/var/tmp/rpm-tmp.RUwFW5: line 38: cd: some_agent-1.0: No such file or directory
error: Bad exit status from /var/tmp/rpm-tmp.RUwFW5 (%prep)


RPM build errors:
    Bad exit status from /var/tmp/rpm-tmp.RUwFW5 (%prep)
[root@laptop ~]$ ^C

Do you have any idea where is my mistake?

I copied the source file but for some reason it's not found.

Answer 1

Look at the log from the build process. First, rpmbuild changes into the BUILD directory:

+ cd /home/rcbandit/rpm/BUILD

Then it untars your source tarball:

+ /usr/bin/gzip -dc /home/rcbandit/rpm/SOURCES/some_agent-1.0.tar.gz
+ /bin/tar -xf -

Then it attempts to cd into the some_agent-1.0 directory, which is presumably created by untarring the source archive:

+ cd some_agent-1.0
/var/tmp/rpm-tmp.RUwFW5: line 38: cd: some_agent-1.0: No such file or directory

This is failing. This suggests that unpacking the archive is not creating the directory RPM is looking for. You would typically solve this using an argument to the %setup macro. For example, if I have an archive named some_agent-1.0.tar.gz, and it contains:

an-unexpected-name/
an-unexpected-name/README

I would need to indicate that with the -n argument to the %setup macro:

%prep
%setup -q -n an-unexpected-name

Answer 2

%install 
install -m 0755 -d %{buildroot}/opt/agent
cp -a your_milion_files/* %{buildroot}/opt/agent

%files 
/opt/agent

When you specify %dir, it will include just that directory and nothing else. Without %dir pragma, it will include that directory and EVERYTHING within it. So you just to copy those files in that directory in %install section.

Edit:

Let say that some-agent-1.0.tar.gz contains:

agent/binary/agent.sh
agent/data/data1.dat
agent/data/data2.dat
....
agent/data/data1000.dat
agent/LICENSE

then your sections should be:

%install
install -m 0755 -d %{buildroot}/%{_bindir}/some-agent
install -m 0755 -d %{buildroot}/%{_datadir}/
cp -a binary/agent.sh %{buildroot}/%{_bindir}/some-agent
cp -a data/* %{buildroot}/%{_datadir}/

%files
%doc LICENSE
%{_bindir}/some-agent
%{_datadir}/some-agent

Instead of the last line you can either use:

%dir %{_datadir}/some-agent
%{_datadir}/some-agent/*

but obviously

 %{_datadir}/some-agent

is shorter and have the same meaning.

In that %install section you can use any bash command. So do there what would you normally do on command line. Any shell expansion works so use that to your advance.

I used some macros - you should use them rather then hardcoded path. You can get full list of available macros by

rpm --showrc

And evaluate them by

rpm --eval '%{_datadir}'

which on recent RHEL and Fedoras evaluato to

/usr/share

I also presented little trick with LICENSE file. When it is present in topmost directory of tarfile, then you just pass the name to %doc macro and rpm will place it to correct %docdir automatically.
