在其它电脑搭建编译该sdk工程的环境，由于所在电脑的linux系统为新装系统（版本:Ubuntu 20.04 LTS），下面记录了编译过程中遇到的问题，以及解决过程供以后参考
问题1：error “Please port gnulib freadahead.c to your platform! Look at the definition of fflush, fread, ungetc on your system, then report this to bug-gnulib.”
freadahead.c: In function 'freadahead':

解决1：
//进入报错目录
$ cd /home/imaginemiracle/Miracle/Linux_Workspace/riscv-object/freedom-u-sdk/work/buildroot_initramfs/build/host-m4-1.4.17
$ sed -i 's/IO_ftrylockfile/IO_EOF_SEEN/' lib/*.c
$ echo "#define _IO_IN_BACKUP 0x100" >> lib/stdio-impl.h
问题2：fatal error: openssl/bio.h: No such file or directory
/home/imaginemiracle/Miracle/Linux_Workspace/riscv-object/freedom-u-sdk/linux/scripts/extract-cert.c:21:10: fatal error: openssl/bio.h: No such file or directory
21 | #include 解决2：
出现这个或者fatal error: openssl/名单.h: No such file or directory。都是没有安装libssl-dev
libssl-dev包含libraries, header files and manpages，他是openssl的一部分，而openssl对ssl进行了实现
$ sudo apt-get install libssl-dev
