2. FD_ZERO, FD_SET, and other functions

Error message:

 

 

Cc1plus: warning: include location "/usr/include" is unsafe for cross-compilation

X11/run. cxx: In function 'int fl_wait (float )':

X11/run. cxx: 461: error: impossible constraint in 'asm'

X11/run. cxx: 462: error: impossible constraint in 'asm'

X11/run. cxx: 463: error: impossible constraint in 'asm'

Solution:

Replace the/usr/include/bits/select. h file with include/bits/select. h In the self-compiled SDK package.

 

3. Modify makeinclude
