Cross compile Qt 5.5.0 for raspberry CM3 lite

[Franckynos]

Hi,

I try to corss-compile Qt for raspberry like as find in this tutorial :

https://visualgdb.com/tutorials/raspberry/qt/embedded/

The "configure" step works but when I try to do "make"

I have this error

In file included from C:/Users/franck/Downloads/qt-everywhere-opensource-src-5.5.0/qtbase/src/3rdparty/pcre/sljit/sljitUtils.c:111:0,

There is a problem with static pthread_mutex_t allocator_mutex = PTHREAD_MUTEX_INITIALIZER; but i don't understand why ? In the sljitUtils.c file I have :

#if (defined SLJIT_EXECUTABLE_ALLOCATOR && SLJIT_EXECUTABLE_ALLOCATOR)

#include <pthread.h>

//UNDER IS LINE 113
static pthread_mutex_t allocator_mutex = PTHREAD_MUTEX_INITIALIZER; 

static SLJIT_INLINE void allocator_grab_lock(void)
{
	pthread_mutex_lock(&allocator_mutex);
}

static SLJIT_INLINE void allocator_release_lock(void)
{
	pthread_mutex_unlock(&allocator_mutex);
}

#endif /* SLJIT_EXECUTABLE_ALLOCATOR */

Someone can help me to compile Qt for raspberry under windows?

Thanks

@Franckynos Why don't you use a more recent Qt version?

[Franckynos]

Because I haven't info for newest version but i'll try

Hi
You can also cheat and just download it ;)

(only 5.7 but might not matter if you just want to test it out)

Problem still exists in Qt 5.15.9

Would be nice if someone can post how they solved it (and moving to a later Qt5 version is not an option because 5.15.9 is the latest at this time)
