compiler_args

Warning

This is a deprecated feature. Please refer to the Migration Guidelines to find the feature that replaced this one.

This is the reference page for compiler_args generator. Go to Integrations/Compilers on command line if you want to learn how to integrate your project calling your compiler in the command line.

Generates a file named conanbuildinfo.args containing a command line parameters to invoke gcc, clang or cl compiler.

You can use the compiler_args generator directly to build simple programs:

gcc/clang:

> g++ timer.cpp @conanbuildinfo.args -o bin/timer

cl:

$ cl /EHsc timer.cpp @conanbuildinfo.args

With gcc or clang
