I have change my program but now there is a problem with compiling.
Now program is
Code:
#include <stdio.h>
unsigned char g_byTemp;
unsigned char g_byBuff[20];
unsigned char g_byBuffr[] = "Hello ";
unsigned char* _ptemp;
unsigned char g_byindex;
void main(void)
{
g_byTemp = 0;
_ptemp = 0;
_ptemp = &g_byTemp;
while (1)
{
g_byTemp++;
sprintf(g_byBuff,"%d",g_byTemp);
for (g_byindex = 0;g_byindex < 10;g_byindex++)
{
g_byBuff[g_byindex] = g_byBuffr[g_byindex];
}
}
}
And the error given by the compiler is
as51 "--edf=C:\Program Files\HI-TECH Software\HC51\PRO\9.70\dat\en_msgs.txt" -o
"-CC:\Program Files\HI-TECH Software\HC51\PRO\9.70\dat\8051-c.ini" -ver=V9.70 -o

I pasted your code into t.c and compiled:
Code:

I tried it with as follows
>C51 --chip=c8051f410 -Bh -V -C main.c
If I remove option -Bh, it works fine.
Actually I was just trying the above sample code to understand the expected changes for a code which works OK with SDCC.
I am looking to compile a huge code with Hitech and based on the manual I tried adding this option.
Does it auto decides to select huge model now?

With the 'F410 only having 32KB of program memory, the huge model is unwarranted in my opinion. Any of the other models should be fine depending on what you mean by "a huge code" and how that "huge code" is currently written.

I don't know whether it "auto decides" a memory model. It defaults to using the small model.

The code size is around 30K and External RAM used as 3.5K.
Referring the manual.pdf that is installed with the compiler, it says available memory model are only small & huge (table 2.5, page 41) while referring the section 3.14 it says Medium model also exist and based on guidelines, it should be a Medium model.
Is there any document exist to guide on the considerations of porting the code for HiTech that are written to other compilers like SDCC?
Thanks

With HI-TECH C PRO there are no medium or small memory models. The huge model (which is not currently implemented) will be provided to deal with code space sizes greater than 64K, but data allocation is done automatically by the code generator and does not require any model selection.
So you do not need to choose a memory model. Once huge model is implemented, you will need to choose it only if you require > 64K code (and have a chip that supports that).
