c: Command not found

[Stan Huang]

@aha_1980 Could you say it in detail how I can check if the compilation environment setup legal or not?

@Stan-Huang

Check the environment variables, especially if PATH is changed or variables like CC.

How do you start Qt Creator?

[Stan Huang]

Just click the Qt-Creator icon from the tool bar.

[SGaist]

Can you run gcc --version in a command prompt ?

I started up Qt-Creator in such way, then it works
1 . open Terminal
2 . execute $~/qtcreator-4.1.0/bin/qtcreator.sh

The "c: command not found" was gone and it built successfully.

The content of qtcreator.sh is:

source /opt/poky/2.1/environment-setup-cortexa9hf-neon-poky-linux-gnueabi .
#! /bin/sh

Use this script if you add paths to LD_LIBRARY_PATH

that contain libraries that conflict with the

libraries that Qt Creator depends on.

makeAbsolute() {
case $1 in
/*)
# already absolute, return it
echo "$1"
;;
*)
# relative, prepend $2 made absolute
echo makeAbsolute "$2" "$PWD"/"$1" | sed 's,/.$,,'
;;
esac
}

me=which "$0" # Search $PATH if necessary
if test -L "$me"; then
# Try readlink(1)
readlink=type readlink 2>/dev/null || readlink=
if test -n "$readlink"; then
# We have readlink(1), so we can use it. Assuming GNU readlink (for -f).
me=readlink -nf "$me"
else
# No readlink(1), so let's try ls -l
me=ls -l "$me" | sed 's/^.*-> //'
base=dirname "$me"
me=makeAbsolute "$me" "$base"
fi
fi

bindir=dirname "$me"
libdir=cd "$bindir/../lib" ; pwd

Add path to deployed Qt libraries in package

qtlibdir=$libdir/Qt/lib
if test -d "$qtlibdir"; then
qtlibpath=:$qtlibdir
fi

Add Qt Creator library path

LD_LIBRARY_PATH=$libdir:$libdir/qtcreator$qtlibpath${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}
export LD_LIBRARY_PATH
exec "$bindir/qtcreator" ${1+"$@"}

@Stan-Huang !
I'm facing the similar problem and the error i have is
c: command not found
My Qt version is 5.9 and i'm using ubuntu 14.04.

-Thanks in advance

Hi @Adarsh_Kumar

do you actually want to cross-compile? If not, then you have another problem.

Hi @aha_1980,
Yes I want to cross compile

[aha_1980]

@Adarsh_Kumar then please tell us more about your setup.

• which target?
• which toolchain did you install and where?
• have you setup Creator for cross compiling? what did you do?

Regards
