Chopping off the last directory in a Makefile variable
Hi everybody,
I have a Makefile where I need to use an environment variable that I set, MYBUILDPATH. The variable can be different depending on the computer, but it always ends with /myBuildRoot/data_tables. Sometimes the data_tables directory will have a slash after it, sometimes not, depending on the computer.
What I'm trying to do is get the location of the build root from this variable (with a slash on the end), so something like this:
I've tried calling the shell from the Makefile:
I've tried a lot of things, including:
And using sed, but no luck.
Would anyone mind pointing me in the right direction to figure this out? I'd appreciate any help.

Hi, I'm trying to run the module load command in a Makefile and i'm getting the following error:
make: module: command not found
Why is this? Is there any way to run this command in a Makefile?

Greetings!
Basically, I would like to properly handle this with gnu make:

%_tool: dir1/%_tool.vf dir2/%_tool/subdir2/%_tool.ver

I make to parse the release version from a text file and set the release version label into a Makefile variable. I tried:
VERSION := `grep vsn s1db.app|sed -e s/*\"// -e s/\"*//`
but looks like make, unlike shell, literally just take the entire `grep ...` as the variable value.
Then I tried... (3 Replies)

Makefile::AST(3pm) User Contributed Perl Documentation Makefile::AST(3pm)NAME
Makefile::AST - AST for (GNU) makefiles
DESCRIPTION
The structure of this (GNU) makefile AST is designed based on GNU make's data base listing output produced by "--print-data-base".
This AST library provides the following classes:
Makefile::AST
The primary class for ASTs. Provides interface for node adding and querying, such as "add_implicit_rule", "apply_implicit_rules",
"add_explicit_rule", "apply_explicit_rules", "add_var", "add_auto_var", "get_var", as well as lots of other utility functions, like
method "eval_var_value" for computing the ultimate values of makefile variables, method "enter_pad" and "leave_pad" for local
variable's scoping pad.
Makefile::AST::Rule::Base
This is the base class for the rule nodes in the AST. It has properties like "normal_prereqs", "order_prereqs", "commands", and
"colon".
Makefile::AST::Rule
This class represents the de-sugared form of simple rules and implicite rules after application. It inherits from
Makefile::AST::Rule::Base, and adds new properties "target" and "other_targets".
Makefile::AST::Rule::Implicit
This class represents the implicit rule nodes in the AST. It inherits from Makefile::AST::Rule::Base, and adds new properties
"targets", "match_anything", and "is_terminal".
Makefile::AST::StemMatch
This class encapsulates the file pattern matching (file names containing "%") and stem substitution algorithms.
Makefile::AST::Variable
It represents the makefile variable nodes in the AST, including "name", "value", "flavor", and "origin".
Makefile::AST::Command
Used to encapsulate information regarding makefile rule commands (e.g. command body, command modifiers "@", "-", "+", and etc.) as a
whole.
LIMITATIONS AND TODO
Adding support for other flavors' makes into this AST library should make a huge amount of sense. The most interesting candiate is
Microsoft's NMAKE.
