how do I compile minichlink on a mac?

Like this: https://github.com/cnlohr/ch32v003fun/wiki/Installation#macos

So basically:

1. Install the toolchain and prerequisites as in the wiki
2. cd to the folder with minichlink
3. Type make and the executable will be built

I've done this a few times on my Mac

I haven't seen those installation instrcutions, but I noticed a makefile inside the minichlink folder, so of course I tried it, and here's what I got:

gcc -o minichlink minichlink.c pgm-wch-linke.c pgm-esp32s2-ch32xx.c nhc-link042.c ardulink.c serial_dev.c pgm-b003fun.c minichgdb.c -lpthread -lusb-1.0 -framework CoreFoundation -framework IOKit -O0 -Wall -Wno-asm-operand-widths -Wno-deprecated-declarations -Wno-deprecated-non-prototype -D__MACOSX__ -I. -I/usr/local/Cellar/libusb/1.0.26/include/libusb-1.0 -L/usr/local/Cellar/libusb/1.0.26/lib warning: unknown warning option '-Wno-deprecated-non-prototype' [-Wunknown-warning-option] 1 warning generated. warning: unknown warning option '-Wno-deprecated-non-prototype' [-Wunknown-warning-option] 1 warning generated. warning: unknown warning option '-Wno-deprecated-non-prototype' [-Wunknown-warning-option] 1 warning generated. warning: unknown warning option '-Wno-deprecated-non-prototype' [-Wunknown-warning-option] 1 warning generated. warning: unknown warning option '-Wno-deprecated-non-prototype' [-Wunknown-warning-option] 1 warning generated. warning: unknown warning option '-Wno-deprecated-non-prototype' [-Wunknown-warning-option] 1 warning generated. warning: unknown warning option '-Wno-deprecated-non-prototype' [-Wunknown-warning-option] 1 warning generated. warning: unknown warning option '-Wno-deprecated-non-prototype' [-Wunknown-warning-option] In file included from minichgdb.c:26: ./microgdbstub.h:735:70: error: use of undeclared identifier 'MSG_NOSIGNAL' ssize_t rx = recv( serverSocket, (char*)buffer, sizeof( buffer ), MSG_NOSIGNAL ); ^ ./microgdbstub.h:793:34: error: use of undeclared identifier 'MSG_NOSIGNAL' send( serverSocket, data, len, MSG_NOSIGNAL ); ^ 1 warning and 2 errors generated. make: *** [minichlink] Error 1 192:minichlink red$ make config make: *** No rule to make target `config'. Stop.

However, I obtained the toolchain from the MounRiverStudio website, not through homebrew...

heh. I moved that define outside the if, and it compiled! Then I run this line

./minichlink -a -w /Users/red/Documents/dev/ch003/CH32V003-makefile-example-main/build/example.hex 0x08000000 -T

and got the following output:

Found WCH Link WCH Programmer is LinkE version 2.9 Chip Type: 003 Setup success Flash Storage: 16 kB Part UUID : 84-22-ab-cd-ec-46-bc-57 PFlags : ff-ff-ff-ff Part Type (B): 07-13-bb-91 Read protection: disabled Interface Setup Fault writing memory (DMABSTRACTS = 08000302) (Execption executing Abstract Command) DMSTATUS: 004c0382 Fault on DefaultWriteWord Part 1 Fault writing memory (DMABSTRACTS = 08000302) (Execption executing Abstract Command) DMSTATUS: 004c0382 Fault on DefaultWriteWord Part 2

with multiple 'fault' lines. I removed -a flag, removed -T flag, but still the same error. And it seems, it corrupts the firmware flashed onto the chip, so that I have to reflash it with openocd to make it work again.

Have you tried using -p to remove the read protection? It can be set by firmware (optionbytes) or by -P.

(i had the same issue, and that brought me to this issue/question)

I take it you resolved your issue @thirstyone ? What needed to change? I can't imagine any sane mac build not having MSG_NOSIGNAL
