I have installed Qt 5.1.1 on my windows 8 machine. I am compiling with mingw and want in link to gsl.
I set my paths to: C:Program Files (x86)GSL-1.13;C:QtToolsmingw48_32bin

1. Eclipse Cannot Open Output File
2. Ubuntu Permission Denied Folder

My pro file is QT += core

Gcc file.c -o fileTest I get the following error: /usr/bin/ld: cannot open output file fileTest: Permission denied collect2: error: ld returned 1 exit status I'm sure that my permissions for the C files are correct, all files have 'rwx' permissions. Do I have to change the permission of the directory as well? I'm a complete newb, so apologies. Eclipse for c程序调试中的问题:cannot open output file study.exe: Permission denied 10-10 阅读数 1010 好不容易配置好了cdt+mingw等，终于可以写程序了，却发现调试时经常遇到cannot open output file study.exe: Permission denied的问题查找了一些资料.

C Permission denied when compiling. Cannot open output file helloworld.exe: Permission denied. And will especially be helpful if I am able to make it into. Steinberg the grand piano 3 vst download full. Jan 28, 2015 Getting a permission denied like that on the.exe seems like your process from a previous build is still running, and you can't write over/build the new exe because of that. Check your computers running processes in Task Manager or something similar.

cout << 'J0(' << x << ') = '

return 0;
}

The errors that I get are,

Ubuntu Permission Denied Folder

When I compiled this program using the command prompt with just MinGW I had an issue with permissions denied and would not create the .exe file unless I ran the command prompt as administrator. I ran qt creator as administrator but still got the same errors.

Anyone have any ideas on what it causing these errors?
