Title: pre-build steps
Post by: LETARTARE on January 13, 2013, 12:56:38 pm

hello,
I read : http://wiki.codeblocks.org/index.php?title=The_build_process_of_Code::Blocks (http://wiki.codeblocks.org/index.php?title=The_build_process_of_Code::Blocks)
and : http://wiki.codeblocks.org/index.php?title=Variable_expansion (http://wiki.codeblocks.org/index.php?title=Variable_expansion) conditional condition

With C::B12.11 Vista Pro
In a project I want to start a conditional order before compilation

Quote

cmd /c echo "Pre-build steps"

I defined in "Project build options->Custom variables"

Quote

GOOD=false

or

Quote

GOOD=true

and in "Project build options->Pre/post build steps"

Quote

$(if(GOOD) ) {cmd /c echo "Pre-build steps" }

I run the generation and I get the result:

Quote

[100,0%] Running project pre-build steps
 (false ) {cmd /c echo "Pre-build steps"} {}
Execution of ' (false ) {cmd /c echo "IRtest2 Pre-build steps"} {}' in 'U:\DONNEES\TRAVAIL_NT\CodeBlock\Arduino\IRtest2' failed.

Is it a mistake on my part or not?
Sincerely

I'm afraid so. In SVN, see how you can use such macros/scripting foo in this project file:
[C::B_SVN]\src\tools\test\macrosmanager\macrosmanager.cbp
It covers pretty much every case.

BTW: From the code its unclear to me if you want use C::B's scripting engine, variable expansion, both, or not... ???

However, the example posted above will help.

Please do note that neither the variable syntax variants %if(...) nor $(if)(...) are supported for this construct.

In your case something like:

Code

cmd /c echo $if($GOOD){"Pre-build steps"}

should work

thank you very much to both.
You are always as effective in your answers
I misread the text !

Error syntax !!
it's correct :

Quote

echo $if($GOOD) {"Pre-build step"}

or

Quote

cmd /c echo $if($GOOD) {"Pre-build step"}

Cordially.
