Arguments

dir

Specifies the local directory that contains copies of target libraries in the corresponding subdirectories.

Default

Off

The compiler uses default settings to search for headers and libraries.

Description

This option specifies the root directory where headers and libraries are located.

For example, if the headers and libraries are normally located in /usr/include and /usr/lib respectively, --sysroot=/mydir will cause the compiler to search in /mydir/usr/include and /mydir/usr/lib for the headers and libraries.

This option is provided for compatibility with gcc.

Note

Even though this option is not supported for a Windows-to-Windows native compiler, it is supported for a Windows-host to Linux-target compiler.
