Macros to access filename

[bjrajendra]

Hello all,

I'm using S32DS for my device S32K144.

I would like to access the project name from the current code. 

Kindly suggest if any macros available or pragmas for accessing the filename.

Thanks in adavance,

Raju

I'm using a very simply (and effective, imho) way: using Eclipse CDT variables which get passed to the compiler/application using -D (defines).

See  How to Use Eclipse CDT Environment Variables in C/C++ Code | MCU on Eclipse 

That way any CDT or environment variable or information can be passed to the application and used there, including the name of the project or other things like if it is a 'release' or 'build' targer, or informatinon about the host operating system.

It is possible of course to use external script extra make files, but the above approach has worked for me for a very long time.

I hope this helps,

Erich

PS: thanks to @BJ RAJENDRANATH  for that question here which finally triggered me to write about the approach I'm using :-)

Hi Enrich,

Thanks for your response.

I moment I added the line __PROJECTNAME__=\"${ProjName}\" in preprocessor symbols I'm getting the errors as sjown in the below picture. Without that line I dont see any errors. 

Do you think, there will be any additional settings to be made along with this. Kindly suggest

Raju

[ErichStyger]

Hi Raju,

I doubt that the error messages are related to the -D addition. You must have changed/broken something else?

Please check (or post) the command line passed to the compiler and linker in the console view.

Erich

Hi Enrich,

The moment I erase the line __PROJECTNAME__=\"${ProjName}\" in -D, the build is successfull.

Also, I created a new project and checked. The result is same. Below shows the addition of CDT variables

Below is the console view during errors.

Hi Raju,

the problem is the way the DS32 is passing parameters to the build process, and that it seems to handle escape sequences in a wrong way. Just use plain double quotes in that case.

I hope this helps,

Erich

[bjrajendra]

Hi Enrich,

I tried keeping PROJECT_NAME="${ProjName}" in the -D and it built succesfully.

Now I tried using the accesing the project name using below. 

static const char projectName[] = PROJECT_NAME;

Now If I build it shows an error as shown below.

Suggest where I went wrong in this

Hi

sounds really like a bug to me in the S32DS, and Jiri already created a ticket for it (thanks!).

I have found a workaround in the S32DS: just do it like this:

I hope this helps,

Erich

[jiri_kral]

Hi Raju, 

It looks there is a bug in passing arguments to build command - https://community.nxp.com/thread/535594#comment-1330515  

Thanks for discovery it! I'll create ticket for that. 

Jiri 

[jiri_kral]

Hi Raju, 

that's the very same error when I tried use IDE variable in preprocessor macro definition. I spend another time to figure out what's wrong - but no success. 

May be Erich will have some comment. Here are expanded build command arguments: 

-DPROJECT_NAME=\"S32K144_Project_HelloClocks\" -DCPU_S32K144HFT0VLLT -I"C:\Users\nxf24838\workspaceS32DS.ARM.2.2\S32K144_Project_HelloClocks/include" -I"C:\NXP\S32DS_ARM_v2.2\eclipse\../S32DS/build_tools/gcc_v4.9/arm_ewl2/EWL_C/include" -I"C:\NXP\S32DS_ARM_v2.2\eclipse\../S32DS/build_tools/gcc_v4.9/arm_ewl2/EWL_C/include/arm" -I"C:\NXP\S32DS_ARM_v2.2\eclipse\../S32DS/build_tools/gcc_v4.9/arm_ewl2/EWL_Runtime/include" -I"C:\NXP\S32DS_ARM_v2.2\eclipse\../S32DS/build_tools/gcc_v4.9/arm_ewl2/EWL_Runtime/include/arm" -O0 -g3 -Wall -c -fmessage-length=0 -mno-pic-data-is-text-relative -msingle-pic-base -mpic-register=r9 -v -ffunction-sections -fdata-sections -mcpu=cortex-m4 -mthumb -specs=ewl_c9x_hosted.specs --sysroot="C:\NXP\S32DS_ARM_v2.2\eclipse\../S32DS/build_tools/gcc_v4.9/arm_ewl2"

[ErichStyger]

I would say it is a bug (or glitch, whatever) how the DS32 build system is dealing with macro expansions and the way the build tools are intergrated. The issue is that the DS32 is placing the wrong content into the .args file.

So

PROJECT_NAME=\"${ProjName}\"

gets transformed into

(side note: the DS32 does use such args files as interface to the build tools instead passing that on the command line).

The solution for the DS32 is to use normal double quotes like this:

Then it gets correctly placed into the .args file:

I hope this helps,

Erich

[jiri_kral]

Hi Erich, 

it looks, not-escaped quotation marks also doesn't work - the quotation marks are ignored when passing to command: 

This is definitely S32DS bug - I'll create JIRA ticket for that. 

Jiri 

[jiri_kral]

Hi Raju, 

I tried define macro for project name in Preprocessor macro definitions, but it looks, that macros based on IDE variables can't be expanded by preprocessor. 

So, if you need project name - you have two options: 

manually define it for example in your main.c file like

#define MY_PROJECT_NAME "MyProjectName"

if you need it updated automatically (when project name is changed or for different project) - you can use pre-build step and start some .bat script which will generate for example proj_name.h file with 

#define MY_PROJECT_NAME "MyProjectName"

line.

"MyProjectName" can be get from filesystem (name of folder where project is) or by parsing .project xml file. 

Anyway, for what purpose you need Project name in your code? 

Jiri 

[bjrajendra]

Thanks Jiri for your response,

The intension of accessing the filename is to store this software image name within the device.

Do you have any .bat scripts which serve this purpose.

Raju.

[jiri_kral]

Hi, 

unfortunately don't have such batch file (actually - this is very first time when I met such requirement).

But writing such batch script should be easy. Here are some basics: 

Output to file - How can I use a batch file to write to a text file? - Stack Overflow 

Getting current directory - windows - Get current batchfile directory - Stack Overflow 

Hope it helps. 

Jiri 

[bjrajendra]

Hi Jiri,

I tried using the batch file with command %~p0, but it gives th complete location of the folder in which the batch file exists, but what exactly I need is the folder alone.

Any possible help in this regard.

Raju

[jiri_kral]

Hi, 

you may find helpful this tutorial - string manipulation in batch script:

[bjrajendra]

Dear Jiri,

As suggested I created a batch file & it generates the header file as well if it's manualaly run the batch file.

But when I added in pre-build steps it generates an error during build & doesn't created a header too. A console is as shown below.

Also, Suggest how to reflect it in the project, as it requires the manual addition of the header file.

Raju

[jiri_kral]

Hi, 

It the project_header.h file contains line with your project definition - you can just include it in main.c (or in source, where you need it) for example. Also make sure, that Project knows path for this header file (or generate this header in /include folder): 

[bjrajendra]

Hi Jiri,

Thanks for the support.

Are you facing the similar issue with pre-processor build which shows as mentioned below.
