I am trying to port windows code into Linux, and it is failing with the following error.

Below is the snippet for the code.

#include <stdio.h>
#include <stdint.h>
#include <wchar.h>

#define FW_VERSION_STRING_SIZE                 8 // Characters including null.
typedef wchar_t WCHAR;

typedef union _FW_VERSION
{
    uint16_t w;
    struct
    {
        uint8_t rev      : 4;
        uint8_t build    : 4;
        uint8_t minor    : 4;
        uint8_t major    : 4;
    } nib;

} FW_VERSION;


typedef struct _FWV
{
       FW_VERSION fwv;                       // version
       WCHAR      s[FW_VERSION_STRING_SIZE]; // string
} FWV;



int main()
{
    struct
    {
        FWV lat = {0}; // latest
        FWV prv ; // previous
        FWV cur; // current
    } suFwVersions;    
}

I am getting the below error.

cc     /tmp/hello.c   -o /tmp/hello
/tmp/hello.c: In function ‘main’:
/tmp/hello.c:34:17: error: expected ‘:’, ‘,’, ‘;’, ‘}’ or ‘__attribute__’ before ‘=’ token
FWV lat = {0}; // latest
        ^
make: *** [/tmp/hello]
Error 1

Is the syntax wrong in Linux, as it succesfully builds in Windows. Gcc version in Linux is 7.3.1

You were using a C++ compiler in Windows. – Antti Haapala -- Слава Україні May 24 '19 at 06:45
What @AnttiHaapala meant is `C` does not support `FWV lat = {0}; // latest` line. – kiran Biradar May 24 '19 at 06:45
`struct FWV lat`, but looking for a duplicate – Antti Haapala -- Слава Україні May 24 '19 at 06:46
@AnttiHaapala But `typedef struct _FWV { ... } FWV;` so `FWV` is a type. – Some programmer dude May 24 '19 at 06:52
@Someprogrammerdude that will do too – Antti Haapala -- Слава Україні May 24 '19 at 06:52
The problem is with the initialization. C doesn't allow initialization inline in structures like you do. C++ on the other hand does allow it. – Some programmer dude May 24 '19 at 06:53

@Someprogrammerdude ah that too... Though it doesn't make any sense, same to initialize the whole lot `= { 0 }` – Antti Haapala -- Слава Україні May 24 '19 at 07:23
