Why strip is not identify header file format on Ubuntu?

[Yash001]

Hi,

I am using Ubuntu 18.04.3 and Qt 5.13.1. I am trying to generate library file for qwt plot library.

My qwt library Location: /usr/local/qwt-6.1
I export qt installation path: export PATH=/opt/Qt/5.13.1/gcc_64/bin/:$PATH

I follow below steps to generate library files:

1) cd /usr/local/qwt-6.1
2) qmake qwt.pro
3) make
4) sudo make install  <--- Header file format is not identify 

strip is not identify header file format.

Here sudo make install output:

cd src/ && ( test -e Makefile || /opt/Qt/5.13.1/gcc_64/bin/qmake -o Makefile /usr/local/qwt-6.1/src/src.pro ) && make -f Makefile install

May I get any suggestion, what should I need to do?

[aha_1980]

@Yash001 and do yourself a favor and build programs as normal user, not as root.

you can compile everything in your home and just exec sudo make install afterwards.

Regards

[sierdzio]

You are building in the same folder make is then installing into. That is very likely to cause trouble.

• remove directory /usr/local/qwt-6.1 completely
• unpack/ checkout qwt to some local directory, like ~/qwt/6.1-src
• then proceed with your qmake, make and sudo make install steps as before

[Yash001]

@sierdzio Thank you sir for response.

I completely remove library from /usr/local/qwt-6.1,and I place my library at ~/Documents/qwt/qwt-6.1. But I got same issue. Any other suggestion?

What install location did you specify?
My qmake location: /opt/Qt/5.13.1/gcc_64/bin/
qwt Package location: ~/Documents/qwt/qwt-6.1

[Christian Ehrlicher]

I've no idea where the strip command is coming from - tested it with 6.1.5 locally and all works fine. Did you modify the qwt config files somehow?

[Christian Ehrlicher]

Ah, can it be that your header files are marked as executable because you copied the files over from windows?

[JonB]

@Yash001
I don't know anything about making Qt, but the Unix strip command is for running on executables, to remove bytes you don't need on final release code. It would never be run on a .h source file. Nor on a .pri or .prf file. So something is wrong.

[Yash001]

@Christian-Ehrlicher

I download from sudo svn checkout svn://svn.code.sf.net/p/qwt/code/branches/qwt-6.1.

However, Yes it is marked as executable. Here the output of ls -al command.

@JonB

Thank you for for explain strip command in detail. Yes, My header files are marked as executable thats why it may executable on all header files.

[Christian Ehrlicher]

Then remove the executable bit. qmake thinks it's an executable otherwise.

[aha_1980]

@Yash001 and do yourself a favor and build programs as normal user, not as root.

you can compile everything in your home and just exec sudo make install afterwards.

Regards

[Yash001]

@aha_1980
some time without root permission I am getting other error.
qmake give permission to header file as executable as @Christian-Ehrlicher said.

what is correct location to install the Qt in Linux /opt/Qt or ~/ or any other location.

Currently my Qt is install at ```/opt/Qt`` location. If I will run qt as normal user then it is not open the serial port. If I will run my qt as root user then it is open the serial port.

Are you recommended to change the Qt location?

Hi,

If it's only a question of serial port access, you should update your user groups to include the one allowed to access the serial port rather than running application as root.

Thank you for quick response.
I will change the the permission of all header files. I am just trying to figure out my Qt location is not install at wrong location. I am curious to know. how permission is assign to newly created file in Linux. Is it inherited from parent folder?

If I will run my qt as root user then it is open the serial port.

Add yourself to the group dialout and you're done.

Do not run programs as root until you know what you are doing. You will brick your system and your data. There is no safety net.

Thank you so much sir, for giving clear idea on access application or utility without root.
