I want to compile an own minimalistic Linux Kernel with make tinyconfig and after doing all steps (like here:)
I get this error message:

Thank you in advance
#ifdef CONFIG_SMP
535 bool apic_id_is_primary_thread(unsigned int id);
536 bool apic_id_disabled(unsigned int id);
537 #else
538 static inline bool apic_id_is_primary_thread(unsigned int id) { return false; }
539 static inline bool apic_id_disabled(unsigned int id) { return false; }
540 #endif
actually you can see the conflict code in /arch/x86/include/asm/apic.h
from these code, enable SMP in your config is the easiest way to fix this problem.
PROCESS:
make menuconfig
-> Processor type and features
enable [Symmetric multi-processing support] there
then
make -j8 # will compile successfully now

I am trying to install a specific version of gnuradio (3.7.10.1). To do so I am not using Pybombs, but I try to do it from source (I am following this).
First I've cloned the github repository, then checkout the appropriate version. It worked fine until I've tried to invoke CMake and build GNU Radio:
mkdir build
cd build
cmake ../
make
During the make, after 6% done, I have the following error:

I am not a Linux expert and I am not very familiar to this compiler/library support. I don't really understand where the error comes from and how to correct it.
I use Ubuntu 18.04.
Coud you give me a hand on this please?
Any help would be very appreciated.
Thanks a lot.
/usr/include/c++/7/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support must be enabled with the -std=c++11 or -std=gnu++11 compiler options.
To resolve the above error you need to compile with -std=c++11 flag. Open CMakeLists.txt, find all occurrences or -std=c++98 and change them to -std=c++11. Then go to the build directory, remove CMakeCache.txt and rebuild
sed -i 's/-std=c++98/-std=c++11/g' CMakeLists.txt
cd build
rm CMakeCache.txt
cmake ..
make
Also as the error is in the cppunit and it's used for testing you can try disabling all tests
cd build
rm CMakeCache.txt
cmake -DENABLE_TESTING=OFF ..
make

Hey folks I'm trying to compile a ELF binary server files from here:https://github.com/LibVNC/libvncserver
To do this I follow the steps here: (starting line 10 - 31). I set the NDK toolchains correctly and now I'm trying to run the $configure command
I'm using a 14.04 Ubuntu Machine.
The following command is succesful
$./configure --host=arm-eabi CC=arm-linux-androideabi-gcc
I then run
$make
and get the following error ($make clean ... doesn't help):

I am using BlueZ 4.101 on an embedded Linux project with Kernel 3.4.79+. Normal Bluetooth operations work great and I can use many headset with my device to transfer Audio. Now I am working towards Bluetooth Compliance and so I am using the Bluetooth SIG's USB PTS Dongle. I am passing every test except for part of the incoming call test where I need to open the SCO connection after accepting a call with the PTS dongle.
The SCO connection attempt works with the headsets but not with the PTS dongle. The error is given from bluetoothd as:
bluetoothd[6306]: audio/headset.c:headset_set_state() State changed /org/bluez/6306/hci0/dev_00_1B_DC_07_30_40: HEADSET_STATE_PLAY_IN_PROGRESS -> HEADSET_STATE_CONNECTED

bluetoothd[6306]: Protocol not supported (93)
So I compiled scotest from the test directory of BlueZ and ran that after connecting with the dongle and got the same result:
# ./scotest -s -b HELLO 00:1B:DC:07:30:40

What am I missing in the Kernel Config to allow the PTS dongle to be put into a Playing state with an open SCO connection?

I instrumented the sco.c file in the kernel with printks.
On success with a normal headset it looks like this after successfully opening SCO connection:
*** sco_sock_create
*** sco_sock_alloc
*** sco_sock_init
*** sco_sock_bind
*** sco_sock_connect
*** sco_connect
*** sco_conn_add
*** sco_chan_add
*** __sco_chan_add
*** sco_sock_set_timer
*** sco_connect_cfm
*** sco_conn_add
*** sco_conn_ready
*** sco_sock_clear_timer
*** sco_sock_getsockopt
*** sco_sock_setsockopt_old
*** sco_sock_getsockopt
*** sco_sock_setsockopt_old
*** sco_sock_sendmsg
*** sco_send_frame
*** sco_sock_sendmsg
*** sco_send_frame
*** sco_sock_sendmsg
*** sco_send_frame
On failure it looks like this:
*** sco_sock_create
*** sco_sock_alloc
*** sco_sock_init
*** sco_sock_bind
*** sco_sock_connect
*** sco_connect
*** sco_conn_add
*** sco_chan_add
*** __sco_chan_add
*** sco_sock_set_timer
*** sco_connect_cfm
*** sco_conn_del
*** sco_chan_get
*** sco_sock_clear_timer
*** sco_chan_del
*** sco_sock_release
*** sco_sock_close
*** sco_sock_kill
*** sco_sock_clear_timer
*** __sco_sock_connect
*** sco_sock_kill
*** sco_sock_kill
*** sco_sock_destruct
Further instrumentation shows the failures are happening in this sco.c function:
void sco_connect_cfm(struct hci_conn *hcon, __u8 status)
{
printk("*** sco_connect_cfm start\n");
BT_DBG("hcon %p bdaddr %pMR status %d", hcon, &hcon->dst, status);
printk("*** sco_connect_cfm_stat hcon %p bdaddr %pMR status %d\n", hcon, &hcon->dst, status);
if (!status) {
struct sco_conn *conn;
conn = sco_conn_add(hcon);
printk("*** sco_connect_cfm sco_conn_add: %d\n",conn);
if (conn)
printk("*** sco_connect_cfm ready\n");
sco_conn_ready(conn);
} else
printk("*** sco_connect_delete: %d\n",status);
sco_conn_del(hcon, bt_to_errno(status));
}
That output looks like this:
*** sco_sock_create
*** sco_sock_alloc
*** sco_sock_init
*** sco_sock_bind
*** sco_sock_connect
*** sco_connect
*** sco_conn_add
*** sco_chan_add
*** __sco_chan_add
*** sco_sock_set_timer
*** sco_connect_cfm start
*** sco_connect_cfm_stat hcon d9ec2400 bdaddr 40:30:07:dc:1b:00 status 26
*** sco_connect_delete: 26
*** sco_conn_del
*** sco_chan_get
*** sco_sock_clear_timer
*** sco_chan_del
*** sco_sock_release
*** sco_sock_close
*** sco_sock_clear_timer
*** sco_sock_kill
*** __sco_sock_connect
*** sco_sock_kill
*** sco_sock_kill
*** sco_sock_destruct
The problem was not the configuration of the Kernel but rather the set of drivers I was using. I had compiled the linux backports ( http://drvbp1.linux-foundation.org/~mcgrof/rel-html/backports/) version of the bluetooth drivers, because I needed the backported wifi drivers, and that gave me the Protocol Not Supported (93) error. I switched back to the drivers distributed with the Kernel 3.4.79+ and it worked.
Hello stackoverflowers :)
For the last several hours I've been trying to compile+load a multiple file module. The compilation emits a strange warning and the module fails to load. Here are the module, Makefile, compilation output and dmesg.
header:
// header.h
#ifndef _HEADER_H
#define _HEADER_H
void do_module_func(void);
void do_other_func(void);
#endif
'main' module file:
//mymodule.c
#include <linux/module.h>
#include <linux/kernel.h>
#include "header.h"
void do_module_func(void)
{
printk(KERN_INFO "module_func\n");
}
static int mymodule_init(void)
{
printk(KERN_INFO "Hello world\n");
do_other_func();
return 0;
}
module_init(mymodule_init);
static void mymodule_exit(void)
{
printk(KERN_INFO "Goodbye, cruel world\n");
}
module_exit(mymodule_exit);
MODULE_LICENSE("GPL")
other c file, which calls do_module_func() that sits in the 'main' module
//other_file.c
#include "header.h"
#include <linux/kernel.h>
void do_other_func(void)
{
printk(KERN_INFO "other_func\n");
do_module_func();
}
Makefile
//Makefile
obj-m := mymodule.o
mymodule-objs := other_file.o
CROSS:=arm-unknown-linux-gnueabi-
KERNEL:= ~/work/linux-davinci-2.6.38/
ARCH:=arm
PWD:=$(shell pwd)
all:
$(MAKE) CROSS_COMPILE=$(CROSS) ARCH=$(ARCH) -C $(KERNEL) M=$(PWD) modules
clean:
$(MAKE) CROSS_COMPILE=$(CROSS) ARCH=$(ARCH) -C $(KERNEL) M=$(PWD) clean
I'm cross compiling but I believe this shouldn't be a problem.
make output:
make CROSS_COMPILE....
make[1]: Entering directory .../linux-davinci-2.6.38
CC [M] .../other_file.o
LD [M] .../mymodule.o
Building modules, stage 2.
MODPOST 1 modules
WARNING: "do_module_func" [.../mymodule.o] undefined! <--- warning here
CC .../mymodule.mod.o
LD [M] .../mymodule.ko
make[1]: Leaving directory .../linux-davinci-2.6.38
insmod output:
can't insert 'mymodule.ko': unknown symbol in module, or unknown parameter
dmesg:
mymodule: Unknown symbol do_mdule_func (err 0)
Thus the module compiles with a (linkage?) warning and the module doesn't load.
Now, I see that in the make output there appears to be a linkage attempt after compiling other_file.c, but shouldn't there be a compilation of also mymodule.c before the linkage?
Thanks! :)
Turns out the problem was in the Makefile. The 'trick' is that you define in obj-m the module that will be compiled (into a .ko) and in the -objs you write all the source files.
Thus the definitions in this Makefile turn to:
obj-m := moduleko.o
moduleko-objs := other_file.o mymodule.o
and this is compiled into moduleko.ko.
This is because file_2 required file_1 symbol reference for building file_2 as LKM.
To overcome this, build file_1(LKM) and place the Module.symvers of file_1 in file_2 location. And build the file_2 again.
all:
$(MAKE) CROSS_COMPILE=$(CROSS) ARCH=$(ARCH) -C $(KERNEL) M=$(PWD) modules
instead try like this
$(MAKE) -C $(KERNEL) ARCH=$(ARCH) CROSS_COMPILE=$(CROSS) M=$(PWD) /
this will run each file and links with object.hope this would solve your problem
