最近在搞机器上的wifi热点,需要移植一大堆东西,如hostapd\wpa_suppliant、dhcp等,这些玩意又依赖其他的一大堆库的移植,比如libnl,openssl等,今天在移植编译libnl-3.4.0出现报错“Relocations in generic ELF (EM: 40)”
详细log如下:

经过查找资料,了解到应该是前后编译器不一样导致,因为在未设置交叉编译器之前我make过一次,失败之后再去配置的,所以只需要clean干净,然后统一用新的交叉编译器编译次即可
void@void-ThinkPad-E450:~/libnl-3.4.0$ ./configure --host=arm-linux --prefix=/usr/local/arm/libnl3.4 CC=/usr/local/arm/gcc-linaro/bin/arm-linux-gnueabi-gcc
void@void-ThinkPad-E450:~/libnl-3.4.0$ sudo make
void@void-ThinkPad-E450:~/libnl-3.4.0$ sudo make install
…........................................
Libraries have been installed in:
/usr/local/arm/libnl3.4/lib/libnl/cli/qdisc
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
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,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to '/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
----------------------------------------------------------------------
/bin/mkdir -p '/usr/local/arm/libnl3.4/etc/libnl'
/usr/bin/install -c -m 644 etc/pktloc etc/classid '/usr/local/arm/libnl3.4/etc/libnl'
make[1]: Leaving directory `/home/void/libnl-3.4.0'
如上则已经成功编译安装。
