Permission denied Hello world Yocto/Openembedded - c

Question

I want to cross compile with Yocto a simple C Hello World for my Colibri iMX7 from Toradex.
The tree of my meta-hellow is as follow :
meta-hellow
├── conf
│ └── layer.conf
└── recipes-myhello
└── files
└── helloworld.c
└── README.TXT
└── myhello_0.0.bb
helloworld.c :
#include <stdio.h>
int main(int argc, char** argv)
{
printf("Hello World!\n");
return 0;
}
myhello_0.0.bb inspired from this one :
DESCRIPTION = "Hello world program"
#To prevent the LICENSE field not set error
LICENSE = "CLOSED"
PR = "r0"
SRC_URI = "file://helloworld.c \
file://README.txt"
do_compile() {
${CC} ${CFLAGS} ${LDFLAGS} ${WORKDIR}/helloworld.c -o helloworld
}
do_install() {
install -m 0755 -d ${D}${bindir} ${D}${docdir}/helloworld
install -m 0644 ${S}/helloworld ${D}${bindir}
install -m 0644 ${WORKDIR}/README.txt ${D}${docdir}/helloworld
}
I have added my layer in my my bblayers.conf like so ${TOPDIR}/../layers/meta-hellow \ and added the package in the local.conf like so IMAGE_INSTALL_append = "myhello".
But the problem I have, after installing it on my board with opkg install, is as follow :
root#colibri-imx7:~# myhello
-sh: /usr/bin/myhello: Permission denied
Why is there a Permission denied since I'm root ? Thank you for your help !

Answer 1

install -m 0644 ${S}/helloworld ${D}${bindir}
You are telling install to set no execute permission for anyone: try "0755" instead.
