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‘:
rm -f t-charset.alias charset.alias && /bin/bash ./config.charset ‘x86_64-pc-linux-gnu‘ > t-charset.alias && mv t-charset.alias charset.alias
freadahead.c:91:3: error: #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."
   91 |  #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."
      |   ^~~~~
fseeko.c: In function ‘rpl_fseeko‘:
make[7]: *** [Makefile:1842: freadahead.o] Error 1
make[7]: *** Waiting for unfinished jobs....
fseeko.c:109:4: error: #error "Please port gnulib fseeko.c to your platform! Look at the code in fseeko.c, then report this to bug-gnulib."

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

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
