问题 I am new to Mingw and C++ programming. I am trying to build a C++ project but getting following error. error: exception handling disabled, use -fexceptions to enable. Where I need to pass this -fexceptions parameter. When I am trying mingw32-make -fexceptions I am getting follwoing error. mingw32-make: exceptions: No such file or directory 回答1: Since you're using Qt, add "exceptions" to the CONFIG variable in your project file (the *.pro file): CONFIG += exceptions This should take care of

问题 MinGW normally when used through the command line spits out the compiled exe of the program in the current working directory, but when used through the gpp-compiler package by kriscross07 in Atom, the exe ends up in a temp folder. I would like it to place the exe in the folder of the source files the same way MinGW would normally.

问题 I am using git-bash/mingw32 on win7. I am trying to install npm: $ npm install sh: npm: command not found. Git-bash is working normally and is installed correctly.

问题 I'm trying to use foreman to run a java app locally which deploys fine to heroku. My Procfile looks like this web: java $JAVA_OPTS -cp target/classes;target/dependency/* Start but when i do formeman start i get 15:51:21 web.1 | unknown command: java $JAVA_OPTS -cp target/classes;target/dependency/* Start If I just enter java at the prompt i get java's help text back so its on my path.
