First API test, error 127.

[JoseCTIControl]

Hello,

We are building our first API in a Connectcore 6UL with Qt, but we keep getting error 127 when debugging.

sudo apt-get install gcc g++ are installed.

This is the output:

Anyone has any ideas? Thanks in advance.

Hi and welcome to devnet,

Something looks wrong here you seem to have c being called rather that gcc

Usually the default build tools are installed using the apt-get install build-essential.

Looks like you are cross-compiling, are you sure the mkspec is setup correctly for your cross-compiler ?

@SGaist said in First API test, error 127.:

Hi,

We have also build-essential installed. Debugger, compiler, sysroot and qmake are those provided by the manufacturer in the toolchain. Cmake is the default /usr/bin/ one.

Specifically, we have 2 compilers (arm-dey-linux-gnueabi-g++ and arm-dey-linux-gnueabi-gcc). Output is the same whichever we use.

mkspec field in the kit tab is empty. No information about it was supplied by the manufacturer in the tutorial.

The module is a i.mx6ul (has no GPU), if it is useful information.

[SGaist]

If possible a link to the tutorial would be nice.

Here you are:

Just explaining toolchain install. Rest is forwarded to yocto wiki.

[SGaist]

Did you create a custom mkspec for that board ?
