Bitbake autotools cannot find makefile-CodePudding

I am attempting to use autotools to build my project. I am using Yocto and bitbake to make a Linux image.

I have read a few automake tutorials and followed a basic guide I found on GitHub. This does not work so well with my current project.

My project structure is as follows:

michael@michael-VirtualBox:~/Documents/MAIN_custom/MAIN_layers/meta-MAINapplication/recipes-core/MAIN_Application$ tree
.
├── files
│   ├── MAIN_Application

autogen.sh:

#!/bin/sh

echo "Generating configure files... may take a while."

autoreconf --install --force && \
  echo "Preparing was successful if there was no error messages above." && \
  echo "Now type:" && \
  echo "  ./configure && make"  && \
  echo "Run './configure --help' for more information"

Makefile.am

AUTOMAKE_OPTIONS = foreign

CFLAGS = -Wall -pedantic -O2
include_HEADERS = main.h

bin_PROGRAMS = EVCC_Application
EVCC_Application_SOURCES = main.c

configure.ac

#                                               -*- Autoconf -*-

AC_PROG_INSTALL
AC_PROG_MAKE_SET
AM_SILENT_RULES([yes])

My bb file is also very simple:

LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

FILESEXTRAPATHS:prepend := "${THISDIR}/files/MAIN_Application:"
FILESEXTRAPATHS:prepend := "${THISDIR}/files/MAIN_Application/src:"
FILESEXTRAPATHS:prepend := "${THISDIR}/files/services:"

SRC_URI = "\
    file://mainapplication.service \
    file://src/utilities/time_conversions.c \
    file://src/main.c \ 
    file://src/scheduler.c \    
    file://include/main.h \ 
    file://include/scheduler.h \        
    file://include/utilities/time_conversions.h \   
    file://Makefile \   
    "

inherit systemd autotools

S = "${WORKDIR}"

SYSTEMD_SERVICE_${PN} = "mainapplication.service"

do_install_append () {
    install -d ${D}${systemd_system_unitdir}
    install -m 0644 ${S}/mainapplication.service ${D}${systemd_system_unitdir}
    sed -i -e 's,@BINDIR@,${bindir},g' ${D}${systemd_system_unitdir}/mainapplication.service
}

When I run autogen.sh in my terminal I get the following output:

configure.ac:4: installing './compile'

Can anyone explain why my bitbake build reports that it cannot find the Makefile.

Edit: Bitbake cannot find my Makefile because it does not exist. I have a Makefile.am. When I rename this to Makefile I get an oe_runmake error.

CodePudding user response：

Here are my comments:

I recommend specifying the full project folder whithout specifying FILESEXTRAPATHS

SRC_URI = "file://MAIN_Application"
SRC_URI  = "file://services/"

Then you need to specify the S variable to the source files folder:

S = "${WORKDIR}/MAIN_Application"

Also, be aware that autotools class will try to look for one of the following files in ${S}:

Makefile
makefile
GNUmakefile

If one exists it will run oe_runmake clean.

So, make sure you name the Makefile correctly and add clean target to it.

Fore more detailed info about how autotools work check the class in this link

EDIT

In order to make sure that everything will go well, run the tasks manually:

Check the S variable value:

bitbake -e mainapplication | grep ^S=

Unpack and check files under S:

bitbake mainapplication -c unpack

You need to see the folder MAIN_Application with its content there.

Try to inherit autotools before systemd.

EDIT2

I tried to create a recipe for your Github example link, and here is the final recipe:

LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://LICENSE;md5=96af5705d6f64a88e035781ef00e98a8"
SRC_URI = "git://github.com/DynamicDevices/bbexample;protocol=https"
PV = "0.1 git${SRCPV}"
SRCREV = "b9fb7785e9e1f357f29bef63dce8f1d91adb6170"
S = "${WORKDIR}/git"
inherit autotools
EXTRA_OECONF = ""

it compiles correctly, so, for your case just set:

LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"

SRC_URI = "\
    file://MAIN_Application \
    file://services \ 
    "

inherit autotools systemd

S = "${WORKDIR}/MAIN_Application"

SYSTEMD_SERVICE_${PN} = "mainapplication.service"

do_install_append () {
    install -d ${D}${systemd_system_unitdir}
    install -m 0644 ${WORKDIR}/services/mainapplication.service ${D}${systemd_system_unitdir}
    sed -i -e 's,@BINDIR@,${bindir},g' ${D}${systemd_system_unitdir}/mainapplication.service
}

I guess you have a typo

FILESEXTRAPATHS:prepend :=

but should be

FILESEXTRAPATHS_prepend :=
