430 compile errors on ubuntu21.10

Linux version 5.13.0-39-generic (buildd@lcy02-amd64-072) (gcc (Ubuntu 11.2.0-7ubuntu2) 11.2.0, GNU ld (GNU Binutils for Ubuntu) 2.37) #44-Ubuntu SMP Thu Mar 24 15:35:05 UTC 2022

$ make
:

I think almost all the compile error came from this project codes.
At first, it seems the line 24 of src/jtag/drivers/aji_client/jtagservice.c to be,
#include <string.h> --> #include <strings.h>
for the func bzero and so forth on the linux box. And some gcc option might be different, such as -Werror=....

After string.h -> strings.h mod, I have,

src/jtag/drivers/aji_client/jtagservice.c:1665:1: error: ‘-mindirect-branch’ and ‘-fcf-protection’ are not compatible
1665 | {
| ^

It seems those compile option might be mistake...

p.s. openocd-code from git have no problem to compile and embeded debug on eclipse.

I have to downgrade gcc/g++ to version 8

[mthii]

gcc version 8 ???

I wrote,

gcc (Ubuntu 11.2.0-7ubuntu2) 11.2.0

Where did you find version 8 ?

[lapd-soc-one]

I used Ubuntu 20.04 and install version 8 as

apt install gcc-8 g++-8
update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-8 100 --slave /usr/bin/g++ g++ /usr/bin/g++-8 --slave /usr/bin/gcov gcov /usr/bin/gcov-8

# Or you can select default gcc to 8 using this command
update-alternatives --config gcc
