问题描述
我想用我的节目一起提供的共享库,而不是使用目标系统的由于版本差异。
I want to supply the shared libraries along with my program rather than using the target system's due to version differences.
LDD
说我的程序使用这些共享库:
ldd
says my program uses these shared libs:
linux-gate.so.1 => (0xf7ef0000)**(made by kernel)**
libc.so.6 => /lib32/libc.so.6 (0xf7d88000)**(libc-2.7.so)**
/lib/ld-linux.so.2 (0xf7ef1000)**(ld-2.7.so)**
我已经成功地通过编译链接ld-xxx.so:
I have successfully linked ld-xxx.so by compiling with:
gcc -std=c99 -D_POSIX_C_SOURCE=200112L -O2 -m32 -s -Wl,-dynamic-linker,ld-2.7.so myprogram.c
但我没有设法成功链接 libc-xxx.so
。我该怎么做?
推荐答案
我发现了如何做到这一点:
I found out how to do it:
rpath的规定,其中所提供的库的位置。此文件夹应包含:libc.so.6的,libdl.so.2,libgcc_s.so.1和也许更多。请与使用strace找出哪些库的二进制文件使用。
rpath specifies where the provided libraries are located. This folder should contain: libc.so.6, libdl.so.2, libgcc_s.so.1 and maybe more. Check with strace to find out which libraries your binary file uses.
ld.so是所提供的链接
ld.so is the provided linker
GCC -Xlinker -rpath = /默认/路径/要/库-Xlinker -I /默认/路径/要/库/ ld.so program.c
gcc -Xlinker -rpath=/default/path/to/libraries -Xlinker -I/default/path/to/libraries/ld.so program.c
