GNU/Linux Options (Using the GNU Compiler Collection (GCC)) (original) (raw)

3.20.18 GNU/Linux Options ¶

These ‘-m’ options are defined for GNU/Linux targets:

-mglibc ¶

Use the GNU C library. This is the default except on ‘*-*-linux-*uclibc*’, ‘*-*-linux-*musl*’ and ‘*-*-linux-*android*’ targets.

-muclibc ¶

Use uClibc C library. This is the default on ‘*-*-linux-*uclibc*’ targets.

-mmusl ¶

Use the musl C library. This is the default on ‘*-*-linux-*musl*’ targets.

-mbionic ¶

Use Bionic C library. This is the default on ‘*-*-linux-*android*’ targets.

-mandroid ¶

Compile code compatible with Android platform. This is the default on ‘*-*-linux-*android*’ targets.

When compiling, this option enables -mbionic, -fPIC,-fno-exceptions and -fno-rtti by default. When linking, this option makes the GCC driver pass Android-specific options to the linker. Finally, this option causes the preprocessor macro __ANDROID__to be defined.

-tno-android-cc ¶

Disable compilation effects of -mandroid, i.e., do not enable-mbionic, -fPIC, -fno-exceptions and-fno-rtti by default.

-tno-android-ld ¶

Disable linking effects of -mandroid, i.e., pass standard Linux linking options to the linker.
