When I launch the value plugin of frama-c, I get many times the same warning :

Has anyone experience these before ?
What is the best way to avoid these and see the meaningful warnings ?
I get this with the simple code :
#include <stdlib.h>
int main (){
char * test = malloc(10);
test[0] = 'a';
}

i want to upload a Script to read out a Lightsensor i have bought. The Sensor is a Grove - Sunlightsensor and the libary for it can be found on GitHub.
The Board i am going to use is a WeMos D1 Mini using a ESP8266, but since many Pins are taken i want to use GPIO2 as SDA and 13 as SCL which can be achieved with: Wire.begin(2,13);
But the Pins are not relavant for compiling.
I want to try the example-script found in the libary from the producer:
#include "Si115X.h"
Si115X si1151;
/**
* Setup for configuration
*/
void setup()
{
uint8_t conf[4];
Wire.begin(2,13);
Serial.begin(115200);
if (!si1151.Begin())
Serial.println("Si1151 is not ready!");
else
Serial.println("Si1151 is ready!");
}
/**
* Loops and reads data from registers
*/
void loop()
{
Serial.print("IR: ");
Serial.println(si1151.ReadHalfWord());
Serial.print("VISIBLE: ");
Serial.println(si1151.ReadHalfWord_VISIBLE());
Serial.print("UV: ");
Serial.println(si1151.ReadHalfWord_UV());
delay(100);
}
But i get the following error massage:
c:\Users\nikol\Documents\Mechatronik_Projekte\Arduino_Sketches\libraries\Grove_Sunlight_Sensor-Si1151\Si115X.cpp: In member function 'int Si115X::read_register(uint8_t, uint8_t, int)':

I already tried using a different compilerversion (2.7.4) but the same error accured.
I might be wrong and not expirienced but the error output seems that something is messed up in the libary itselfe?
Thanks for any help. If further information is needed i am happy to give it to you.
I've a Cypress BLE module and have compilation problem with IAR.
In "ezsapi.h" are defined this macros:
#ifdef __GNUC__
/* standard GNU C */
#ifdef _WIN32
/* MinGW, Cygwin, TDM-GCC, etc. */
#define __PACKDEF(STRUCTNAME, STRUCTDEF) typedef struct STRUCTDEF __attribute__((__packed__,gcc_struct)) STRUCTNAME
#else
/* generic gcc */
#define __PACKDEF(STRUCTNAME, STRUCTDEF) typedef struct STRUCTDEF __attribute__((__packed__)) STRUCTNAME
#endif
#define ALIGNED __attribute__((aligned(0x4)))
#else
/* Microsoft Visual C++ */
#define __PACKDEF(STRUCTNAME, STRUCTDEF) __pragma(pack(push, 1)) STRUCTDEF __pragma(pack(pop)) STRUCTNAME
#define ALIGNED
#endif
IAR usually use #pragma pack(push,1) and #pragma pack(pop) and I tryed to modify the macro in:
#define __PACKDEF(STRUCTNAME, STRUCTDEF) #pragma(pack(push, 1)) STRUCTDEF #pragma(pack(pop)) STRUCTNAME
With original macros the errors reported is:
ezsapi.h(694) : Error[Pe020]: identifier "pack" is undefined
ezsapi.h(694) : Error[Pe018]: expected a ")" ezsapi.h(694) :
Error[Pe079]: expected a type specifier ezsapi.h(694) : Error[Pe260]:
explicit type is missing ("int" assumed) ezsapi.h(694) : Error[Pe141]:
unnamed prototyped parameters not allowed when body is present
ezsapi.h(694) : Error[Pe130]: expected a "{"
and with my macro the errors reported is:
(69 is the line where the macro is located)
ezsapi.h(69) : Error[Pe052]: expected a macro parameter name
ezsapi.h(69) : Error[Pe052]: expected a macro parameter name
ezsapi.h(694) : Error[Pe020]: identifier "pack" is undefined
ezsapi.h(694) : Error[Pe018]: expected a ")" ezsapi.h(694) :
Error[Pe079]: expected a type specifier ezsapi.h(694) : Error[Pe260]:
explicit type is missing ("int" assumed) ezsapi.h(694) : Error[Pe141]:
unnamed prototyped parameters not allowed when body is present
ezsapi.h(694) : Error[Pe130]: expected a "{"
What's the correct formula for IAR?
What's escaping me?
Thanks.
There are two ways of solving this problem. My suggestion is that you use the __packed type attibute instead of #pragma pack() as this has a more well defined meaning. This, however, needs IAR language extensions to be switched on. If you can't enable language extensions or for some other reason need to use pack-pragma you have to use an alternative pragma syntax to be able to include it in a preprocessor macro. If you use _Pragma("pack(push,1)") and _Pragma("pack(pop)") you macro should work as expected. Definitions of PACKDEF for both alternatives are shown below:
#define PACKDEF(STRUCTNAME, STRUCTDEF) typedef __packed struct STRUCTDEF STRUCTNAME
#define PACKDEF(STRUCTNAME, STRUCTDEF) _Pragma("pack(push,1)") typedef struct STRUCTDEF STRUCTNAME _Pragma("pack(pop)")
We started seeing a lot of warnings like this after upgrading to Xcode 9.3:
Macro expansion producing 'defined' has undefined behavior
Like this:
#if MIXPANEL_FLUSH_IMMEDIATELY // ==> Warning: Macro expansion producing ...
[self flush];
#endif
And this:
#if !MIXPANEL_NO_AUTOMATIC_EVENTS_SUPPORT // ==> Warning: Macro expansion producing
- (void)setValidationEnabled:(BOOL)validationEnabled {
_validationEnabled = validationEnabled;
...
}
#endif
I guess the Macro can't be nested in Xcode 9.3.
I have these warnings too.
The Macro was defined like this, which cause the warnings:
#if TARGET_OS_MAC
#define SCENEKIT_SDK_AVAILABLE defined(POP_USE_SCENEKIT)
#elif TARGET_OS_IPHONE
#define SCENEKIT_SDK_AVAILABLE defined(POP_USE_SCENEKIT)
#endif
and I fixed it like this:
#if defined(POP_USE_SCENEKIT)
# define USE_SCENEKIT 1
#else
# define USE_SCENEKIT 0
#endif
#if TARGET_OS_MAC
#define SCENEKIT_SDK_AVAILABLE USE_SCENEKIT
#elif TARGET_OS_IPHONE
#define SCENEKIT_SDK_AVAILABLE USE_SCENEKIT
#endif
I seperated the Macro "SCENEKIT_SDK_AVAILABLE" like that, and the warnings were gone.
You can try my way.

It seems like some libraries missing. What should I do now? Thanks!
Looks like you need to specify cmake toolchain file in cmake arguments:
cmake -DCMAKE_TOOLCHAIN_FILE=../libs/kaa/toolchains/esp8266.cmake \
-DKAA_PLATFORM=esp8266 ..
Please, refer documentation for details.
It might be related to step 5 Install ESP8266 RTOS SDK in the tutorial you referenced from the Kaa website.
Did you run the command sed -i 's:#include "c_types.h"://#include "c_types.h":' $ESP_SDK_HOME/include/lwip/arch/cc.h?
I remember I had a similar (or the same) problem and forgot to execute this command. It comments out an #include which conflicts with the declaration of types elsewhere.
You need to edit the build.sh file,
find build() and change the code:
build() {
mkdir -p "$PROJECT_HOME/build"
cd "$PROJECT_HOME/build"
cmake ..\
-DKAA_TARGET=esp8266\
-DCMAKE_TOOLCHAIN_FILE=../libs/kaa/toolchains/esp8266.cmake \
-DBUILD_TESTING=OFF \
-DKAA_PLATFORM=esp8266 \

I have recently installed MS Visual Studio 2015 with the Arduino plugin "Visual Micro".
Everything works fine, upload a sketch etc. Except when I try to compile my code when I use FreeRTOS. I downloaded the FreeRTOS libary through the Arduino IDE (library manager). Therefore(in MS VS 2015) I could chose to include the library in MS VS 2015. So I included the library in one of my sketches. Below you see my code example. Within the Arduino IDE i can compile the code and upload it to the device, but in MS VS there are some errors.

If you read the error messages, the issue is explained clearly.
include Arduino_FreeRTOS.h must appear first.
Your example shows it included last.
Put it first and the errors will go away.
Arduino_FreeRTOS.h includes many definitions that are used in other places, hence the need for it to be first.
Unrelated to your question, but using delay() is nasty as it consumes CPU cycles needlessly. Try vTaskDelay() as alternative which defers (or blocks) to the Scheduler to unblock other Tasks or run the idle Task which is the Arduino loop() function.
The loop() function can then put the CPU to sleep, reducing power consumption. See the feilipu.me post on topic for more.
vTaskDelay() counts Ticks, so hence the need to divide by the Tick period in milliseconds. i.e.
Time in ms / portTICK_PERIOD_MS = Ticks

Found the issue, the includes where in the wrong order: dont know why;).
You cant only include freeRTOS in MS VS you need to correct the order of the includes by yourself.
Here is the correct order:
#include <Arduino_FreeRTOS.h>
#include <croutine.h>
#include <event_groups.h>
#include <FreeRTOSConfig.h>
#include <FreeRTOSVariant.h>
#include <list.h>
#include <mpu_wrappers.h>
#include <portable.h>
#include <portmacro.h>
#include <projdefs.h>
#include <queue.h>
#include <semphr.h>
#include <StackMacros.h>
#include <task.h>
#include <timers.h>
I'm not sure about the Arduino code you are referring to, but normally there is no reason to include FreeRTOSConfig.h directly - instead include FreeRTOS.h first, and that will get the ordering of the port layer files and FreeRTOSConfig.h files correct for you, then include the header files that contain the API functions you want to use.
