我为我的raspbian制作了一个带有crosstool-ng的交叉编译器。它成功编译了一个hello单词测试程序，但是当我编译我的gtk测试程序时（使用来自raspberry pi的gtk库）它编译好了，但是当我尝试在树莓中运行它时我得到了这个：
pi@raspberrypi ~ $ ./gtk_test
gtk_test: symbol lookup error: gtk_test: undefined symbol: gtk_progress_get_type
我的ldd输出似乎很好：
pi@raspberrypi ~ $ ldd ./gtk_test

有人可以解释一下吗？谢谢！
答案 0 :(得分：0)
最后我弄清楚问题是什么：
使用-v -Wl编译，-verbose并查看输出显示rpi_sysroot / usr / lib / arm-linux-gnueabihf / libc.so（脚本）试图链接错误的库。要修复刚打开的libc.so并从中更改：
/* GNU ld script
Use the shared library, but some functions are only in
the static library, so try that secondarily. */
OUTPUT_FORMAT(elf32-littlearm)
GROUP ( /lib/arm-linux-gnueabihf/libc.so.6 /usr/lib/arm-linux-gnueabihf/libc_nonshared.a
AS_NEEDED ( /lib/arm-linux-gnueabihf/ld-linux-armhf.so.3 ) )
到此：
/* GNU ld script
Use the shared library, but some functions are only in
the static library, so try that secondarily. */
OUTPUT_FORMAT(elf32-littlearm)
GROUP ( ../../../lib/arm-linux-gnueabihf/libc.so.6 ../../../usr/lib/arm-linux-gnueabihf/libc_nonshared.a AS_NEEDED ( ../../../lib/arm-linux-gnueabihf/ld-linux-armhf.so.3 ) )
所以它指向正确的覆盆子库
编辑： 一个更简单的解决方案是删除rpi_sysroot / usr / lib / arm-linux-gnueabihf / libc.so和rpi_sysroot / usr / lib / arm-linux-gnueabihf / libc.a，使链接器回退到libc的交叉编译器版本的.so
