编译通过,在当前目录生成libcurl_test可执行文件
将/home/zhaojq/libcurl目录下的所有文件和pkgconfig目录都拷贝到ARM设备上文件系统的/lib目录,
将libcurl_test拷贝到ARM设备上
将libcurl_test拷贝到ARM设备上
执行./libcurl_test
./libcurl_test: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory
./libcurl_test: error while loading shared libraries: libssl.so.1.0.0: cannot open shared object file: No such file or directory
libcurl运行需要libssl.so.1.0.0的库,ARM移植openssl-1.0.0s.tar.gz详见另一篇文章

移植成功再次执行./libcurl_test
