Trying to include httpclient.h inside ldebug.c is causing an error during compilation

My goal is to do an http post request inside ldebug.c by including httpclient. It worked in dbg_printf.c but I'm getting compilation errors in ldebug.c.

In file included from ../ldebug.c:28:0:
../../http/httpclient.h:69:24: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'http_request'
 void ICACHE_FLASH_ATTR http_request(const char * url, const char * method, const char * headers, const char * post_data, http_callback_t callback_handle, int redirect_follow_count);

Is there another way I can do a post request?

ICACHE_FLASH_ATTR is a macro defined in the file c_types.h

There are two reasons that it wouldn't be defined.

First, ldebug.c may not include c_types.h or include a file which #includes c_types.h. This is easy to fix - edit ldebug.c and add

#include <c_types.h>

before #include <httpclient.h>

The other possibility is that the symbol ICACHE_FLASH is not defined when ldebug.c gets compiled. The file c_types.h only defines ICACHE_FLASH_ATTR if ICACHE_FLASH is #define'd. If the first fix doesn't work, you'll need to make sure that you #define ICACHE_FLASH when you compile ldebug.c

The easiest way to do this is to add

#define ICACHE_FLASH 1

as the very first line of ldebug.c

Or you can make sure that you set -DICACHE_FLASH=1 as a compiler flag in whatever your development environment is. Changing ldebug.c is almost certainly the easier way to do this.
