Other Parts Discussed in Thread: CC3200
Hello,
I'm struggling with this error for a few days now and it seems to me to be a bug. I'm trying to compile Zlib to a CC3200 LaunchPad so I've downloaded it and defined as #define Z_SOLO which eliminates use of external libraries. At first place it compiles fine. Using the inflate() function also goes fine because it only requires a few source files of the library. However, when using deflate() function I need to include a few more files and then I get these errors:
Description Resource Path Location Type #10192 Failed linktime optimization CC3200_HTTP_Server C/C++ Problem gmake: *** [CC3200_HTTP_Server.out] Error 1 CC3200_HTTP_Server C/C++ Problem gmake: Target 'all' not remade because of errors.

It's finding incompatible definitions between trees.c file and deflate.h. So apparently deflate.c and trees.c both include deflate.h.
-in trees.c there are the functions imlpementations (include deflate.h)
-in deflate.h there are the functions prototype
-in deflate.c it only uses those functions (include deflate.h)
Looking at the error description I found out the function definition is striclty the same:
error: symbol "_tr_align" redeclared with incompatible type: "void(deflate_state *)" in "C:/Users/Felipe Ribas/TI_Workspace/Zlib/trees.c" at line 892 and: "void(deflate_state *)" in "C:\Users\Felipe Ribas\TI_Workspace\Zlib\deflate.h" at line 302)
and the same goes for the other functions. I though it was a macro problem but I generated the pp files.
deflate.pp:
void _tr_init (deflate_state *s); int _tr_tally (deflate_state *s, unsigned dist, unsigned lc); void _tr_flush_block (deflate_state *s, charf *buf, ulg stored_len, int last); void _tr_flush_bits (deflate_state *s); void _tr_align (deflate_state *s); void _tr_stored_block (deflate_state *s, charf *buf, ulg stored_len, int last);
trees.pp:
void _tr_init (deflate_state *s);
int _tr_tally (deflate_state *s, unsigned dist, unsigned lc);
void _tr_flush_block (deflate_state *s, charf *buf, ulg stored_len, int last);
void _tr_flush_bits (deflate_state *s);
void _tr_align (deflate_state *s);
void _tr_stored_block (deflate_state *s, charf *buf, ulg stored_len, int last);
void _tr_init(s)
deflate_state *s;
{
...
Then I ran a few tests declaring the function without the S parameter and it was fine. Only when using deflate_state * s the problem would appear. Then I thought maybe the structure was being declared differently so I checked the pp files again:
trees.pp

ulg static_len;
uInt matches;
uInt insert;
ush bi_buf;
int bi_valid;
ulg high_water;
} deflate_state;
And then I also realized that _tr_tally() follows the same pattern then the other functions but it doesnt raise an exception as the others do.
Does anyone have any idea why I'm getting this error and how could I fix it? Or even, what further tests should I do? I also tried with TI 5.2.5 and TI 15.12.1 compilers. Same thing...
Thanks!
