Unable to link NLohmann json library using cmake

I am trying to link the NLohmann json library to my json interpreter via cmake.
I keep getting the error :
fatal error: 'nlohmann/json.hpp' file not found #include <nlohmann/json.hpp>
From the file :
#include <nlohmann/json.hpp>
#include <fstream>
#include "InterpretJson.h"
#include "game.h"
using namespace std;
using json = nlohmann::json;
InterpretJson(string path){
this->path = path;
ifstream f(path);
json jData = json::parse(f);
f.close();
this->data = jData;
}
Game interpret(Game& game){}
The CMakeLists.txt in the directory which contains src/interpretJson.cpp and include/interpretJson.h.:
find_package(nlohmann_json 3.2.0 REQUIRED)
add_library(interpreter
src/interpretJson.cpp
)
target_include_directories(interpreter
PUBLIC
$<INSTALL_INTERFACE:include>
$<BUILD_INTERFACE:${CMAKE_CURRENT_SOURCE_DIR}/include>
PRIVATE
${CMAKE_CURRENT_SOURCE_DIR}/src
${nlohmann_json_INCLUDE_DIR}
)
target_link_libraries(interpreter
PRIVATE
${nlohmann_json_LIBRARIES}
)
set_target_properties(interpreter
PROPERTIES
LINKER_LANGUAGE CXX
CXX_STANDARD 17
)
install(TARGETS interpreter
ARCHIVE DESTINATION lib
)
How do I fix this?
Edit: This is issue is only happening on arm64 Mac M1 but it is working fine on a linux ubuntu VM. However, the vm is slow and I would still like to know how to make it work on Mac

Undefined references in Apache user-written module

I have some undefined reference errors in an Apache module. I've cut the source code down to a minimum that reproduced the error. Below is the source for "mod_test.c" ...
#include "httpd.h"
#include "http_config.h"
#include "http_request.h"
#include "http_protocol.h"
#include "http_core.h"
#include "http_main.h"
#include "http_log.h"
#include "ap_mpm.h"

#include <stdio.h>
#include <stdlib.h>
#include <errno.h>
#include <string.h>
#include <sys/types.h>
#include <arpa/inet.h>
#include <netdb.h>
module AP_MODULE_DECLARE_DATA test_module;
static int test_handler(request_rec *r);
static int test_init(apr_pool_t *p, apr_pool_t *plog, apr_pool_t *ptemp, server_rec *s);
/* Structure containing state information for the module */
typedef struct {
} ns_mod_config;
static int ns_typematch(request_rec *r) {
ns_mod_config *ns_scfg = ap_get_module_config(r->server->module_config,
&test_module);
core_request_config *creq_cfg;
creq_cfg = ap_get_core_module_config(r->request_config);
return 0;
}
module AP_MODULE_DECLARE_DATA test_module = {
STANDARD20_MODULE_STUFF,NULL,NULL,NULL,NULL,NULL,NULL};
I am using a more-or-less standard Makefile for compiling the module (note that the install option has been removed as this is a test to demonstrate the problem.)
APXS=/usr/local/apache2/bin/apxs
APXS_OPTS=-Wc, -Wc,-DDST_CLASS=3
SRC=src/mod_test.c
OBJ=src/.libs/mod_test.so
$(OBJ): $(SRC)
#echo
$(APXS) $(APXS_OPTS) -c $(SRC)
#echo
#echo write '"make install"' to install module
#echo
clean:
rm -f src/.libs/*
rm -f src/*.o
rm -f src/*.lo
rm -f src/*.la
rm -f src/*.slo
rmdir src/.libs
The compile fails as follows:
/usr/local/apache2/bin/apxs -Wc, -Wc,-DDST_CLASS=3 -c src/mod_test.c

.
Makefile:23: recipe for target 'src/.libs/mod_test.so' failed
make: *** [src/.libs/mod_test.so] Error 1
I am not sure how this can occur. http_core.h is present in /usr/local/apache2/include and it does include the definitions that are claimed missing by the compile. Six other modules on the same system compile without errors, though none of them use this specific reference to the core data structures.
Help will be gratefully received.
After posting to the Apache modules mailing list, it develops that the problem is in two parts.
Defining CORE_PRIVATE is required under Apache 2.2 to have access to the core data structures.
ap_get_core_module_config is an Apache 2.4 construct.

Issue with CMake when using glib library

I am writing a bluez C program to read battery service. I am using CMake for building the code.
My Cmake File is :
# CMakeLists file for module-bluez project
cmake_minimum_required(VERSION 3.02)
project (bluez-module)
find_package(PkgConfig REQUIRED)
# Adding dbus library
pkg_check_modules(DBUS REQUIRED dbus-1>= 1.6)
include_directories(${DBUS_INCLUDE_DIRS})
link_directories(${DBUS_LIBRARY_DIRS})
#Adding glib library
pkg_check_modules(GLIB REQUIRED glib-2.0>=2.23)
include_directories(${GLIB_INCLUDE_DIRS})
link_directories(${GLIB_LIBRARY_DIRS})
pkg_check_modules (DBUSGLIB REQUIRED dbus-glib-1)
include_directories(${DBUSGLIB_INCLUDE_DIRS})
link_directories(${DBUSGLIB_LIBRARY_DIRS})
# Adding bluetooth using extra libs
list(APPEND EXTRA_LIBS "bluetooth")
# Expose 'gattlib.h' to all sub-directories
include_directories(include)
add_executable(bluez-module scantest.c)
# Linking libraries
message(${DBUSGLIB_LIBRARIES})
target_link_libraries(bluez-module ${EXTRA_LIBS})
#target_link_libraries(bluez-module ${DBUS_LIBRARIES})
target_link_libraries(bluez-module ${DBUSGLIB_LIBRARIES})
target_link_libraries(bluez-module ${GLIB_LIBRARIES})
I have to use g_main_loop in my code. But after building the source file I always get the below error :
[ 50%] Linking C executable bluez-module
CMakeFiles/bluez-module.dir/scantest.c.o: In function `read_battery_service':
scantest.c:(.text+0x5b8): undefined reference to `g_dbus_setup_bus'
collect2: error: ld returned 1 exit status
My read_battery function code is as below :
int read_battery_service(struct hci_state *current_hci_state , char *dev_addr)
{
GError *error = NULL;
GDBusClient *client;
GOptionContext *context;
context = g_option_context_new(NULL);
main_loop = g_main_loop_new(NULL, FALSE);
dbus_conn = g_dbus_setup_bus(DBUS_BUS_SYSTEM, NULL, NULL);
return 0;
}
Just trying to initialize for to access dbus apis.
I have included these headers in the code
#include <assert.h>
#include <stdlib.h>
#include <errno.h>
#include <unistd.h>
#include <sys/ioctl.h>
#include <bluetooth/bluetooth.h>
#include <bluetooth/hci.h>
#include <bluetooth/hci_lib.h>
#include <stdio.h>
#include <gdbus.h>
#include <glib/gmain.h>
What would be the issue ? Is glib.h contains the function g_main_loop_new ? Where should I find it ? Or Is CMake not linking glib properly ?
Looks like you are missing the gdbus linker flags. Try using
pkg_check_modules (DBUSGLIB REQUIRED dbus-glib-1) and add
target_link_libraries(module-bluez ${DBUS_LIBRARIES} ${DBUSGLIB_LIBRARIES})
and see if it helps.

GCC errors out on code that used to work fine

I have a program that has successfully compiled in the past, but now I get a bunch of errors.The source code is just:
#include <stdio.h>
#include <sys/types.h>
#include <sys/stat.h>
int main()
{
int fd;
fd = creat("datafile.dat", S_IREAD | S_IWRITE);
if (fd == -1)
printf("Error in opening datafile.dat\n");
else
{
printf("datafile.dat opened for read/write access\n");
printf("datafile.dat is currently empty\n");
}
close(fd);
exit (0);
}
Now I get the errors:
cre.C:8:54: error: ‘creat’ was not declared in this scope
cre.C:16:17: error: ‘close’ was not declared in this scope
cre.C:17:16: error: ‘exit’ was not declared in this scope
Sometimes I get an error about gxx_personality_v0 instead, and sometimes I get no error at all! I've tried updating gcc, but the problem remains. What's going wrong?
OS UBUNTU 12.1 on vaio laptop
From your error messages I see that you called your file cre.C. gcc is case-sensitive for file names: try naming it cre.c and compiling it.
$ LANG=C cc -o foo foo.C
foo.C: In function 'int main()':
foo.C:8:54: error: 'creat' was not declared in this scope
foo.C:16:17: error: 'close' was not declared in this scope
foo.C:17:16: error: 'exit' was not declared in this scope
but
$ LANG=C cc -o foo foo.c
foo.c: In function 'main':
foo.c:17:9: warning: incompatible implicit declaration of built-in function 'exit' [enabled by default]
As noted in a comment, a file with .C extension is handled by the C++ compiler, thus you are seeing those errors.
Read the man pages for the creat, close, and exit functions.
On my system, creat() requires:
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
close() requires:
#include <unistd.h>
and exit() requires:
#include <stdlib.h>
As for why the code was compiling before, it's hard to tell. Perhaps the compiler was being invoked in a more permissive mode that didn't complain about missing function declarations, or perhaps some of the headers you do include have #include directives for the headers you need.

How to create custom toolbar in sencha touch?

I want a custom toolbar with background color as gradient.
I tried with sass. But still it is not working.. What i did, i am writing it step by step:
I create on resources folder in my current project.
I kept themes and images folder there.
I created css and sass folder inside resources folder.
in the sass folder i created app.scss file which contains the below code:
$base-color: #588aad; // go big blue!$include_default_icons: false;
#import 'sencha-touch/default/all';
#include sencha-panel;
#include sencha-buttons;
#include sencha-sheet;
#include sencha-picker;
#include sencha-tabs;
#include sencha-toolbar;
#include sencha-toolbar-forms;
#include sencha-indexbar;
#include sencha-list;
#include sencha-layout;
#include sencha-form;
#include sencha-msgbox;
#include sencha-loading-spinner;
#include pictos-iconmask("bookmarks");
#include pictos-iconmask("compose");
#include pictos-iconmask("trash");
#include pictos-iconmask("search");
#include pictos-iconmask("bookmark2");
#include sencha-toolbar-ui('charcoal', #333333,'glossy');
Then i created config.rb file with this code:
dir = File.dirname(FILE)
load File.join(dir, '..', 'themes')
sass_path = dir
css_path = File.join(dir, "..", "css")
environment = :production
output_style = :compressed
then i run compass compile app.scss in the comand prompt
In css folder, app.css file has been created after running the command.
7.then i change the code for toolbar:
xtype: 'toolbar', docked: 'top',
ui: 'charcoal',
title: 'Set Compliance Goals'
But after that when i am running the project, in simulator, toolbar is coming with white background.... please help..
check in your web browser's inspector that the css is targeting x-toolbar.And empty your browser cache might help.
It's also possible that your config.rb is misconfigured- this is a good resource on config.rb setup for compass
Depending on the version of ST you are using you might want to use Sencha Cmd. Makes it a lot easier.
In Sencha Cmd you can create a starting point by building an empty app. After that is complete you can run the sencha app watch command from the app root folder and any sass changes will compile automatically along with many other processes.
MyApp/resources/sass/app.scss --> compiles to --> MyApp/resources/css/app.css
// THIS WILL OVERRIDE THE DEFAULT SENCHA TOOLBAR UI THEMES
#include sencha-toolbar-ui('normal', $base-color, 'glossy');
#include sencha-toolbar-ui('dark', $second-color, 'matte' );
// THIS ONE USES A CUSTOM UI. THERES COMPASS MIXINS IN THE INCLUDED
// TO MAKE A GRADIENT OUT OF THIS COLOR.
#include sencha-toolbar-ui('custom-ui-name', $third-color, 'glossy');
This works for me. If you want to control the gradient then you can check how here in the docs http://docs-origin.sencha.com/touch/2.4/2.4.1-apidocs/#!/api/Ext.Toolbar-css_mixin-sencha-toolbar-ui
Hope this helps!
