Running stunnel 4.56 or 5.00 on an ARM platform (ARM926EJ) with Linux 2.6.36.4, I encounter the following error : the call to connect() return -1, but errno is set to 0 !

If stunnel is configured to use fork mode instead of pthread mode, the problem disapear.

So it seems there is a problem, cross-compiling the program, with errno or __errno_location() in the program generated with pthread.

I add the definition of _REENTRANT, without success ...

(See $H1 at http://pauillac.inria.fr/~xleroy/linuxthreads/faq.html)

Is somebody meet the same error ?

The errno definition in the Android framework (as an example of Linux/ARM platform) is:

/* internal function returning the address of the thread-specific errno */ extern volatile int* __errno(void);

/* a macro expanding to the errno l-value */ #define errno (*__errno())

It seems okay.

How do you reproduce this problem? What are the stunnel debug logs when it happens?
