Where can I find information about semantics of build-depends field in .cabal file?
My interpretation is that it is misleading and quite bad for the user experience:
cabal will figure out what are dependencies for a package to install when asked
cabal will find a plan along with matching versions
cabal will require you to manually enter all transitive dependencies in a .cabal file (with version ranges) to build a project
If a library has a "convenience" wrapper, does my cabal file have to look like this?
build-depends: base >= 4.7 && < 5
, diagrams >= 1.0
, diagrams-core >= 1.0
, diagrams-lib >= 1.0
, diagrams-contrib >= 1.0
, diagrams-svg >= 1.0

When I try to install tmap:
install.packages("tmap")
I have the following mistake:
also installing the dependencies ‘tmaptools’, ‘sf’
There are binary versions available but the source versions are later:
binary source needs_compilation
sf 0.9-0 0.9-2 TRUE
tmap 2.3-2 3.0 FALSE

So I guess this is a problem with the sf version, but when I try to install sf independently, it is the version 0.9-0. that I install, and I cannot install 0.9.1 or more as required.
Any tip to overcome this issue?
Thanks!
PS: I use R version 3.6.3

When I try to install multiples packages with a wildcard naming I got the following error:
* yum_package[mysql-server] action install (up to date)
* yum_package[mysql*] action install
* No candidate version available for mysql*
============================================================================ ====
Error executing action `install` on resource 'yum_package[mysql*]'
============================================================================ ====
Recipe code is:
package 'mysql-server' do
action :install
end
package 'mysql*' do
action :install
end
You have to use the exact package name. The chef package resource does no magic to find matching packages.
The name of the resource (the part just after package) is used as the package name and given to the underlying system (yum on RH like systems, apt on debian like systems)
If you have multiples packages to install and a common configuration you can loop over them in your recipe instead:
['mysql-server','mysql-common','mysql-client'].each do |p|
package p do
action :install
end
end
The array creation could be simplified with some ruby syntax as the words builder %w:
%w(mysql-server mysql-common mysql-client).each [...]
Since chef 12.1 the package resource accept an array of packages directly like this:
package %w(mysql-server mysql-common mysql-client)
This can be resolved using chef cases. Please see below
add the following to your attributes file:
packages = []
case node[:platform_family]
when 'rhel' #based on your OS
packages = [
"package1",
"package2",
"package3",
"package4",
"package5",
"package6",
"package7" ## Last line without comma
]
end
default[:cookbookname][:packages] = packages
Then, add the following to your recipe file (recipes/default.rb):
node[:cookbookname][:packages].each do |pkg|
package pkg do
action :install
retries 3
retry_delay 5
end
end
Running chef-solo (Installing Chef Omnibus (12.3)) on centos6.6
My recipe has the following simple code:
package 'cloud-init' do
action :install
end
log 'rpm-qi' do
message `rpm -qi cloud-init`
level :warn
end
log 'yum list' do
message `yum list cloud-init`
level :warn
end
But it outputs the following:
- install version 0.7.5-10.el6.centos.2 of package cloud-init
* log[rpm-qi] action write[2015-07-16T16:46:35+00:00] WARN: package cloud-init is not installed
[2015-07-16T16:46:35+00:00] WARN: Loaded plugins: fastestmirror, presto
Available Packages
cloud-init.x86_64 0.7.5-10.el6.centos.2 extras
I am at a loss as to why rpm/yum and actually rpmquery don't see the package as installed.
EDIT: To clarify I am specifically looking for the following string post package install to then apply a change to the file (I understand this is not a very chef way to do something I am happy to accept suggestions):
rpmquery -l cloud-init | grep 'distros/__init__.py$'
I have found that by using the following:
install_report = shell_out('yum install -y cloud-init').stdout
cloudinit_source = shell_out("rpmquery -l cloud-init | grep 'distros/__init__.py$'").stdout
I can then get the file I am looking for and perform
Chef::Util::FileEdit.new(cloudinit_source.chomp(''))
The file moves based on the distribution but I need to edit that file specifically with in place changes.
Untested code, just to give the idea:
package 'cloud-init' do
action :install
notifies :run,"ruby_block[update_cloud_init]"
end
ruby_block 'update_cloud_init' do
block do
cloudinit_source = shell_out("rpmquery -l cloud-init | grep 'distros/__init__.py$'").stdout
rc = Chef::Util::FileEdit.new(cloudinit_source.chomp(''))
rc.search_file_replace_line(/^what to find$/,
"replacement datas for the line")
rc.write_file
end
end

I would better go using a template to manage the whole file, what I don't understand is why you don't know where it will be at first...
Previous answer
I assume it's a compile vs converge problem. at the time the message is stored (and so your command is executed) the package is not already installed.
Chef run in two phase, compile then converge.
At compile time it build a collection of resources and at converge time it execute code for the resource to get them in the described state.
When your log resource is compiled, the ugly back-ticks are evaluated, at this time there's a package resource in the collection but the resource has not been executed, so the output is correct.
I don't understand what you want to achieve with those log resources at all.
If you want to test your node state after chef-run use a handler maybe calling ServerSpec as in Test-Kitchen.
I am stuck with the installation of TPC-E EGen on Mac OS X (or Linux). I have downloaded the workload generator from TPC website : www.tpc.org/tpce/egen-download-request.asp but I failed to build it.
When using the following command for building the utilities:
cd Utilities/prj/GNUMake/
make
I receive the following error:
../../prj/GNUMake/Makefile.EGenUtilities:136: ../../obj/DateTime.d: No such file or directory
../../prj/GNUMake/Makefile.EGenUtilities:136: ../../obj/EGenVersion.d: No such file or directory
../../prj/GNUMake/Makefile.EGenUtilities:136: ../../obj/error.d: No such file or directory
../../obj/locking.d:3: *** missing separator. Stop.
which is not a meaningful error and does not help in how to resolve the issue.
Any help or hint would be appreciated.
I found the problems:
1- in EGenStandardTypes.h, I had to replace
\#if defined (__unix) || (_AIX)
by
\#if defined(unix) || defined(\__unix__) || defined(\__unix) || defined(\__APPLE__) && defined(\__MACH__) || (_AIX)
in order to make this part of code work for Mac OS X as well.
2- in DateTime.cpp and error.cpp
I had to comment out #error directive usages, as my current version of GCC did not support it.
