Problem setting a variable inside a target

[Ed L Wolf]

Hello

 

I am having some trouble trying to set a variable inside a target. When reading the variable, it comes up blank. Below is my make file code. The eval statement below highlighted in red is not working. Can you provide some assistance please? I am using GNU Make 4.1

 

$(DIR_A2LGEN_SETUP)/McData-setup.a2l: $(BSW_A2LS)  $(DIR_SCRIPTS)/update_mcdata_a2l.py $(DIR_SCRIPTS)/update_copyright_info.py $(DIR_SCRIPTS)/merge_a2l_files.py $(DIR_TARGET)/$(PROJECT).odx-f $(DIR_A2L)/Merger.ini
