[Sdcc-user] stm8flash compile fails under MacOS X

[Georg Icking-Konert]

hi all,

for the STM8 Discovery board I want to use Valentin's stm8flash tool (https://github.com/vdudouyt/stm8flash) for flashing via SWIM / ST-Link. This board has no UART<->USB connection and therefore cannot be programmed via UART boot loader —> need a SWIM tool

Unfortunately I wasn’t able to compile the tool on my Mac. Here's my steps with observations:

installed pkg-config and libusb via Homebrew --> worked
compile of stlink.c gave

many warning messages like (ignored):
stlink.c:37:71: warning: passing 'char [32]' to parameter of type 'unsigned char *' converts between pointers to integer types with different sign [-Wpointer-sign]
--> suppose this is not critical...? Disabled all warnings by CFLAGS += -w in Makefile

many error messages like (fixed):
/usr/local/Cellar/libusb/1.0.19/include/libusb-1.0/libusb.h:1696:10: error: use of undeclared identifier ‚NULL'
--> fixed by #include <stddef.h> in stlink.c before #include <libusb.h>

many error message like (open):
stlink.c:340:12: error: use of undeclared identifier ‚stderr'
fprintf(stderr, "Unknown status: %x\n", status);
In addition it warns that
declaration of built-in function 'fprintf' requires inclusion of the header <stdio.h>
--> it seems like the inclusion of <stdio.h> in line 4 of stlink.c has no effect... :-(

to make sure my toolchain is ok, I compiled a dummy program with fprintf(stderr,"test"); and it was ok
—> I played around a lot but can't get that stdio.h error fixed. Apparently the compiler "forgets“ the stdio.h declarations completely and I have no clue, why
 :-(


Hardware Setup:
iMac running MacOS X 10.10.3
"gcc -v“ yields:
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1
Apple LLVM version 6.1.0 (clang-602.0.49) (based on LLVM 3.6.0svn)
Target: x86_64-apple-darwin14.3.0
Thread model: posix
HW works under Windows on a VirtualPC, i.e. STVD could flash & debug the board on the same Mac and USB port
Anybody has idea what's going wrong, or maybe even succeeded in compiling the tool for MacOS X? For your help thanks a lot in advance!

Regards,
Georg Icking

Does the attached patch help?

Hi Philipp,

first of thanks a lot for the patch! However, I am new to paths and seem to be unable to apply it :-( Specifically:

I copied the patch from your mail and saved it as Unix textfile to root of folder stm8flash
command "patch -p1 < stm8flash.patch“ —> patch: **** malformed patch at line 6: .PHONY: all clean
command "git apply --stat stm8flash.patch“ —> fatal: corrupt patch at line 6

—>
where do I need to copy the patch to? I suppose it’s the root of folder stm8flash
?
what command do I need to call with what parameters?
anything else I have to consider?
maybe this is a stupid question, but is there a reason why this patch isn’t simply applied to Valentin’s repository?

For your help thanks a lot in advance!

He applied it yesterday. I sent it to him at the same time as I sent it
to you. So you can just try his current version now.
