system verilog - How to write a makefile where the compiled object files are in a different directory with a different name? -

so i'm trying write makefile use questasim , systemverilog files. if don't know (and people won't) don't worry, it's not relevant problem.

i have project director containing: src/ work/ makefile

the src/ directory contains several directories each contain source files.

the work/ directory doesn't exist, , created makefile.

when call "compiler" called vlog, on .sv file directory gets created in work folder same name .sv file without suffix. in directory 3 files 1 i'll use "object' file _primary.dat.

so example, calling "vlog src/interface/my_interface.sv" creates (if succeeds) work/my_interface/_primary.dat

my .sv files need compiled in specific order, , want compile them if source file or 1 of dependencies has changed.

i can turn path .sv file path relevant _primary.dat file using "$(addsuffix /_primary.dat, $(addprefix $(vlib_dir)/, $(basename $(notdir $(src)))))" reverse impossible, loose directory structure.

so think want sort of map object -> src. in $(obj): target, can "vlog $(getsrc $@)".

after have deal compile order , dependencies, can work out.

any suggestions?

i found solution works. i'm not sure it's neatest, i'll post here else has problem.

basically create macro takes 2 arguments: .sv source file path , name, , list of dependencies. turns source file path object file path , creates target. dependency on source file , passed in dependencies. create variable containing list of sources. do: $(foreach src,$(srcs),$(eval $(call create_target_for, $(src)))) creates targets.

additionally have each subdirectory phony target, relevant dependencies, allowing me correct compile order on directories.

the thing missing if need ensure files in single directory have correct compile order.

my makefile:
