You need to build and run makefsdata, which is in Middlewares/Third_Party/LwIP/src/apps/httpd/makefsdata

try the top of the repository, sorry

STM32Cube/Repository/STM32Cube_FW_F4_V1.21.0/Middlewares/Third_Party/LwIP/src/apps/httpd/makefsdata

makefsdata is a c program that generates fsdata.c [or fsdata_custom.c, if you so choose]

Shall I import it in the projet? sorry but I did not understand how to use makefsdata to get the fsdata.c ?

makefsdata is a stand-alone utility.  I suggest browsing the LwIP documentation

You have either got to compile makefsdata.c for your host PC, or download a precompiled .EXE, and have it enumerate and process the directory/file structure you want the server to access. It creates a 'File System' where no storage media or subsystem exists.

I'm sure there are FAQ, tutorials and videos about this if you're remotely interested in learning how to use the tools.

An example use case can be found in the software trees

\STM32Cube_FW_F4_V1.21.0\Projects\STM324xG_EVAL\Applications\LwIP\LwIP_IAP\Src\fsdata.c

Use Google to find information and tutorials

Microsoft and GNU have PC based C compilers that can take C code and make executables/applications that run natively.

KI am using LWIP , STM32F4 and I want to iimplement an http web based on netconn API in the board. 

I activated httpd from CubMX, I downloaded makefsdata.exe from internet and I generated with it the fsdata.c file.. 

In the fs.c generated by CubMX there is error in the fnction fs_open

in the programm of the http I am using I wrote this 

file = fs_open(''/STM32F4xx_files/stm32.jpg'');

In fs.c file  

err_t

fs_open(struct fs_file *file, const char *name)

{

const struct fsdata_file *f;

if ((file == NULL) || (name == NULL)) {

return ERR_ARG;

}

I did not understand the error exactly 

You will find attached the capture of the error and the programm

thank you in advance for your help

If you read the LwIP documentation, you will find that you have to write your own custom fs_open to do what you want to do

else if((strncmp(buf, 'GET /STM32F4xx.html', 19) == 0)||(strncmp(buf, 'GET / ', 6) == 0))

{

/* Load STM32F4x7 page */

file = fs_open('/STM32F4xx.html');

netconn_write(conn, (const unsigned char*)(file->data), (size_t)file->len, NETCONN_NOCOPY);

fs_close(file);

}

else

{

/* Load Error page */

file = fs_open(&file,'/404.html');

netconn_write(conn, (const unsigned char*)(file->data), (size_t)file->len, NETCONN_NOCOPY);

fs_close(file);

}

Indeed in this htppd.c usage of fs_open is inconsistent. 

If this code comes from some 'static'  template, need to fix it.

Or, get updated sources from the home site of LwIP project.

Yes I corrected it like this 

struct netbuf *inbuf;

err_t recv_err;

char* buf;

u16_t buflen;

struct fs_file * file;

....

....

/* Check if request to get ST.gif */

if (strncmp((char const *)buf,'GET /STM32F4xx_files/ST.gif',27)==0)

{

recv_err = fs_open(file,'/STM32F4xx_files/ST.gif');

netconn_write(conn, (const unsigned char*)(file->data), (size_t)file->len, NETCONN_NOCOPY);

fs_close(file);

}

 But i get a warning sayin ' file may be used unitialized in this function .wht does this mean ?? it is declared u nthe begining of the function

Thank you for help

Try this:

struct fs_file file;

recv_err = fs_open(&file,'/STM32F4xx_files/ST.gif');
