C2H compiling error

I built my C code with cycloneII SOPC design in NiosII IDE without any problem and I can see the result in ModelSim..but when I want to accelerate a function(loopH) of my code using C2H,it doesn't build the whole code any more.

and find an error in a line contained this code:

unsignedchar * str;

the error shown in Problems TAB:

C2H C2H ERROR: "c:/altera/91/nios2eds/components/altera_avalon_c_hardware_accelerator/lex_and_yacc/c2h_cparse.exe" "G:/hello_world_0/Debug/obj/hello_world.c2h_pre" hello_world_0 line 0 1265494093645 72

PARSE ERROR, ../hello_world.c line 72 column 13 hello_world_0 hello_world.c line 72 1265494093645 71

NOTE:My project name was Hello world

_______________________________________________________

how can I find an alternative for this part of code which C2H can support and translate it?:confused:

    Is the variable defined in the middle of a block?

    C2H doesn't support that C99 'feature' and requires that all variable definitions be at the start of program blocks.

    thank you dsl..you were right.I shifted all of the variable definitions to the start of program blocks and that error vanished.but after building the project I faced to another error which doesn't point to my code lines..!!
