地址无关代码,在64位下编译动态库的时候,经常会遇到下面的错误 /usr/bin/ld: /tmp/ccQ1dkqh.o: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC 提示说需要-fPIC编译,然后在链接动态库的地方加上-fPIC的参数编译结果还是报错,需要...

-m32 选项来决定是否生成32位机器代码。如果在64位系统上,要禁止生成32位代码, 设置 --disable-multilib。 --enable-gather-detailed-mem-stats 允许收集详细的内存使用信息,如果设置该参数为 enable,则将来编译好的gcc可执行程序,可以通过 -fmem-report 选项来输出编译其它程序时的实时内存使用情况。 --with-long...
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) -...
The script to compile with -O2 option is: Raw /usr/bin/gcc -c -m32 -ansi -D_GNU_SOURCE \ -funsigned-char -fno-zero-initialized-in-bss -fno-strict-aliasing \ -DLANGUAGE_C -Wall -Wno-strict-aliasing -Wextra -Werror \ -O2 \ -pipe -Wstrict-prototypes -Wmissing-prototypes test_code...
When I try to execute a 32-bit file compiled with gcc -m32 main.c -o main on Windows Subsystem for Linux, I get the following error: bash: ./main: cannot execute binary file: Exec format error. If I compile it without -m32 it runs. Any solution for running 32-bit executable...

For example, you might compile a file "some_class.m"like this:复制 gcc -g -fgnu-runtime -O -c some_class.m 1.In this example, -fgnu-runtime is an option meant only for Objective-C programs; you can use the other options with any language supported by GCC....
