Build error while importing a simple project from a makefile

[kevinmeal]

I've looked up on the forum before posting this question, but couldn't find any hints.

Here is the structure of the makefile

BASIC = common/code1.o common/code2.o common/code3.o common/code4.o

OBJECTS = \
	main_code_1 \
	main_code_2


all: ${BASIC} $(OBJECTS) values

${BASIC}: common/code1.hh common/code3.hh common/code4.hh common/different_code.cpp

$(OBJECTS): ${BASIC}

values:
	cd get_values; $(MAKE) $(MFLAGS)

main_code_2: ${BASIC} additional_code.o

clean: 
	rm -f *.o ${BASIC} $(OBJECTS) get_values/get_values

dist-clean: clean

The directory tree is the following:

├── common
│   ├── code1.cpp
│   ├── code1.hh
│   ├── code2.cpp
│   ├── code2.hpp
│   ├── different_code.cpp
│   ├── code3.cpp
│   ├── code3.hh
│   ├── code4.cpp
│   └── code4.hh
├── get_values
│   ├── datab.cpp
│   ├── datab.h
│   └── reader.cpp
├── additional_code.cpp
├── additional_code.hpp
├── main_code_1.cpp
├── main_code_2.cpp

How to specify the sources for each specific targets in the .pro file?
I tried to put everything in the SOURCES and HEADERS variable but it doesn't work like the make file dependencies.

Thanks in advance.

Hi @kevinmeal

• how does your *.pro file looks now?
• which error do you get exactly?
• if you want to generate separate targest, you should probably use qmakes SUBIDR template to create your project structure: https://wiki.qt.io/SUBDIRS_-_handling_dependencies

I solved it temporarily by compiling the object files for the subdirectories (using make directly in the shell) then linking them as libraries in the .pro file.
Then I added main_code.cpp as SOURCES .
