Qt execvp: permission denied

jastmc

I'm using Qt4 and Qt Creator on Ubuntu 13.10. I want to debug directly on the Beaglebone hardware. With the simplest Qt GUI application with just a pushbutton on the UI, I get the error below. It compiles OK for the desktop build. CAn anyone tell me whats causing this?

There is a red exclaimation mark beside the Beaglebone kit, when I hover over it, it says:

may be you used "uic" binary compiled for x86?

I do not know what you mean by "uic".

What I do know is that I am using the Arm cross compiler and it cross-compiles OK from a terminal window.

Hi, I've solved that issues.... here my solution.

You must to add, the environment variables that corresponding at BBB Toolchain. in Qt creator, Projects tab, build option , in Build Environment section.

add this..

Set OE_QMAKE_UIC3 to /usr/local/angstrom/arm/bin/uic34
Set PATH to $SDK_PATH/bin:$PATH
Set PKG_CONFIG_PATH to $SDK_PATH/$TARGET_SYS/usr/lib/pkgconfig
Set PKG_CONFIG_SYSROOT_DIR to $SDK_PATH/$TARGET_SYS
Set QMAKESPEC to /usr/local/angstrom/arm/arm-angstrom-linux-gnueabi//usr/share/qtopia/mkspecs/linux-g++
Set SDK_PATH to /usr/local/angstrom/arm
Set TARGET_SYS to arm-angstrom-linux-gnueabi
Set alias opkg to "LD_LIBRARY_PATH=$SDK_PATH/lib $SDK_PATH/bin/opkg-cl -f $SDK_PATH//etc/opkg-sdk.conf -o $SDK_PATH"
Set alias opkg-target to "LD_LIBRARY_PATH=$SDK_PATH/lib $SDK_PATH/bin/opkg-cl -f $SDK_PATH/$TARGET_SYS/etc/opkg.c
