compiling in ARMv7h fails

saber

qt 5.11 , arch linux
my app builds fine on 64 bit architer both x86 and arm64 .but it is failling in amrv7h .i really can't find the cause .here is the compile output.

NT : I am creating an armv7h chroot and using qemu to chroot into it and compile.
what is the cause?

Could you please describe your environment?
Are you cross-compiling your application?
From your compile ouput I can see something that could be a clue:

qemu: Unsupported syscall: 397

What are you using Qemu for?

saber

i am Linux 64bit .i am not cross-compiling.
it is build by a distro maintainer.he use the qemu for building .it will take forever to build it in actual architecter.
he is facing this issue.

and i am not an expert on qemu or arm.
he is facing this issue when he build my app on armv7h.on arm64 it builds fine.
also i am not finding any like qemu: Unsupported syscall: 397.

The cross compiled Qt for armv7h is missing the modules mentioned in this error message...
"make[1]: Leaving directory '/home/manjaro/corebox/src/build/library'" - also, you should NOT build from the source code directory! Use out of source builds. Else you will end up with build artefacts from previous builds (for other platforms) which will cause troubles.

@jsulm
we are trying to build it in ARCH .and the qt package's are from arch-arm.
if the problem in packages then we have nothing to do .
nd as you told we are not building it in source directory . we are making a separate folder , place build files in the build folder and keep the source files separated.

saber

it was solved by adding this lines.

	#ifdef __LP64__
		off_t offset;
	#else
		la_int64_t offset;
	#endif

Hi,

Where exactly did you add these lines ?
