Android doesn't support all posix threading stuff. However there is a work around.

Include this file in files where you get pthread related errors. I trust you can do that independently.

Thank you I will try 😊

Can you guide me where I need to add this file? I already installed libbthread

[Pyogenics]

Include it wherever you receive pthread errors. From the error in you original message, you should include the file in sgminer.c. You may still get errors in other places.

Please @Pyogenics help me sir.. after add #include now i got a single error.. please help..

[Pyogenics]

Try #include <pthread> in bthread.h

[Saikatsaha1996]

Try #include <pthread> in bthread.h

Okay okay trying

[Saikatsaha1996]

Try #include <pthread> in bthread.h

@Pyogenics WWWWoowwww nice pthread-cancel problem solved 🤗😋🥰

New error found.. but I think it is not pthread-cancel related ..

Thank you so much.. thank you soooo much for your help 😊..!.. finding solutions long time ago.. actually i don't know any programing language that's why facing problem..

I am not miner.. but trying to experiential purpose only..

[Pyogenics]

I will have to look at the code, further reply will come later.

@Pyogenics hello sir!.. after completing with gcc last error solved.. but getting undefined reference to `pthread_cancel'

[Saikatsaha1996]

@Pyogenics ultimately cgminer building done .. Sgminer can't build because of getting undefined reference to pthread-cancel

But sir without your help i can't.. thank you for your help cgminer working fine.. clang did not compile.. i build with gcc..

and also edited some code.. #include bthread.h && #include athread.h

include

include

define SIG_CANCEL_SIGNAL SIGUSR1

define PTHREAD_CANCEL_ENABLE 1

define PTHREAD_CANCEL_DISABLE 0

static int pthread_setcancelstate(int state, int *oldstate) { sigset_t new, old; int ret; sigemptyset (&new); sigaddset (&new, SIG_CANCEL_SIGNAL);

ret = pthread_sigmask(state == PTHREAD_CANCEL_ENABLE ? SIG_BLOCK : SIG_UNBLOCK, &new , &old);
if(oldstate != NULL)
{
    *oldstate =sigismember(&old,SIG_CANCEL_SIGNAL) == 0 ? PTHREAD_CANCEL_DISABLE : PTHREAD_CANCEL_ENABLE;
}
return ret;

}

static inline int pthread_cancel(pthread_t thread) {

pthread_kill(thread, SIG_CANCEL_SIGNAL);

}

After that build completed.. 🤠🤠❤️❤️❤️ thank you so much @Pyogenics

[Saikatsaha1996]

@Pyogenics Sir My mistake i am a big idiot...🥲 All problem solved with just need to install libbthread and add -lbthread flag

Now all build done sgminer also ..

Thank you .. Build done without a single error 😊 Thank you sooooo much for your big help.. ❤️❤️❤️ And thank you too libbthread @tux-mind ..
