静态库链接时搜索路径顺序:1. ld会去找GCC命令中的参数-L2. 再找gcc的环境变量LIBRARY_PATH3. 再找内定目录 /lib /usr/lib /usr/local/lib 这是当初compile gcc时写在程序内的动态链接时、执行时搜索路径顺序:1. 编译目标代码时指定的动态库搜索路径;2. 环境变量LD_LIBRARY_PATH指定的动态库搜索路径;3....
9.4的gcc源代码有个错误,报PATH_MAX未定义,搜了一下头文件中的定义,最大是4096,手工改成4096之后编译通过: libtool: compile: /home/ronghua.zhou/zrh/gcc-9.4.0/xxx_aarch64_gcc9.4.0_glibc2.23linux_build/./gcc/xgcc -shared-libgcc -B/home/ronghua.zhou/zrh/gcc-9.4.0/xxx_aarch64_gcc9.4.0_gl...

We need to compile our library source code into position-independent code (PIC):1 $ gcc -c -Wall -Werror -fpic foo.c Step 2: Creating a shared library from an object file Now we need to actually turn this object file into a shared library. We’ll call it : ...
Compile only, do not link 只进行编译,不链接 --asm Output assembly code as well as object code 输出汇编以及obj文件 -S Output assembly code instead of object code 只输出汇编文件 --interleave Interleave source with disassembly (use with --asm or -S) 交叉反汇编 (use with --asm or -S) -...

gcc -shared -o foo.o 步骤2:根据目标文件创建一个共享链接库 gcc -shared -o foo.o 这个命令创建了一个名为的共享链接库 Step 3: Linking with a shared library As you can see, that was actually pretty easy. We have a shared library. Let’s compile our main.c and link it with libfoo....
only linked into executables. Usually these options are used to compile code that will be linked using the ‘-pie’ GCC option. 说明: PIE是GCC与操作系统的产物,提供了地址无关的功能。ASLR是基础,只有操作系统开启了ASLR功能时,-fpie选项添加的随机化特征才会在程序加载和运行时展现。
