error: 'QTextStream' dose not name a type

[HMCL]

Hello, I want to run GCS program in ubuntu 18.04.1. When I run GCS program in Qt 5.14.2, error occurs. I don't know why the error occurs.

'QTextStream' does not name a type. How can I solve this error? Please give any advice or comment. Thank you!

@HMCL So, it is about https://github.com/MishkaRogachev/JAGCS.git, right?
Did you try to build on command line like shown in https://github.com/MishkaRogachev/JAGCS/blob/master/README.md ?

[HMCL]

@jsulm Yes I built JAGCS through cmake .. , make. Next, I made project file through command : 'qmake -project' and 'qmake JAGCS.pro'. Then, when I enter the command 'make' the above error occurs.

@HMCL said in error: 'QTextStream' dose not name a type:

Next, I made project file through command : 'qmake -project' and 'qmake JAGCS.pro'.

Why?
QtCreator supports CMake. There is no need to create pro file.

@jsulm For the first time I build the JAGCS, there is no launch file or .exe file. How can I launch the program without qmake JAGCS.pro?

For the first time I build the JAGCS

Was the build successful? Also, which build steps did you follow? From the README.md:

mkdir build
cd build
cmake ..
make

Did you clone the repository properly:

git clone --recursive https://github.com/MishkaRogachev/JAGCS.git

?
I don't know how the executable is named and where it is located.
Don't know why you think creating pro file will help you.

@jsulm I will retry the process. Thank you for your comment. I am little confused because I have been tried many method so I don't really remember whole process I done.

@jsulm I solve the problem! Like you said, there is no need to create pro file. I found the launch file in 'result' folder! Thank you for your advice.
