specify the full pathname of the library, or use the `-LLIBDIR' flag during linking and do at least one of the following: - add LIBDIR to the `LD_LIBRARY_PATH' environment variable during execution - add LIBDIR to the `LD_RUN_PATH' environment variable during linking - use the `-Wl...
Optionsof the form -fflag specify machine-independentflags. Most flags have both positive and negativeforms; the negative form of -ffoo would be-fno-foo. In the table below, only one of theforms is listed---the one you typically will use. You can figure out the other form by either r...
#为了方便,添加PATH export LD_LIBRARY_PATH=/lustre/gene/local/gmp-6.1.0/lib:$LD_LIBRARY_PATH export C_INCLUDE_PATH=/lustre/gene/local/gmp-6.1.0/include:$C_INCLUDE_PATH export LD_LIBRARY_PATH=/lustre/gene/local/mpfr-3.1.4/lib:$LD_LIBRARY_PATH export C_INCLUDE_PATH=/lustre/gene/local/m...
#include:这个就是把后面的文件直接拷贝到预处理指令的位置,当然这里也会处理依赖include的问题,比如A文件 include B文件,而B文件又include了C文件,那么在A里面是看到C文件的内容的。还有有个盲区就是,include是可以include xxx.c的,这个在C语言的语法上是没有任何问题的,大家千万别以为只能C文件 include 头文件。

●命令gcc首先调用cpp进行预处理,在预处理过程中,对源代码文件中的文件包含(include)、预编译语句(如宏定义define等)进行分析。 ●接着调用cc1进行编译,这个阶段根据输入文件生成以.o为后缀的目标文件。汇编过程是针对汇编语言的步骤,调用as进行工作,一般来讲,.S为后缀的汇编语言源代码文件和汇编、.s为后缀的汇编语...
Try the --with-gmp, --with-mpfr and/or --with-mpc options to specify their locations. 因为缺少gcc依赖的gmp、mpfr、mpc三个软件。同时gmp与mpfr及mpc之间还有相互依赖关系,所以 要按下面顺序安装,并在 configure后面的选项后面带上所依赖软件的路径....
