在 Linux 的任何主要包中,running./configure --help
都会在最后输出:
Some influential environment variables:
CC C compiler command
CFLAGS C compiler flags
LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
nonstandard directory <lib dir>
CPPFLAGS C/C++ preprocessor flags, e.g. -I<include dir> if you have
headers in a nonstandard directory <include dir>
CPP C preprocessor
Use these variables to override the choices made by `configure' or to help
it to find libraries and programs with nonstandard names/locations.
如何使用这些变量来包含目录?我尝试运行./configure --CFLAGS="-I/home/package/custom/"
,./configure CFLAGS="-I/home/package/custom/"
但是这些不起作用。有什么建议么?
