尝试使用libtomcrypt库时出现Contiki微粒类型创建错误(RSA公钥生成) [英] Contiki mote type creation error when trying to use libtomcrypt library (rsa public key generation)
问题描述
我正在尝试为我的学校项目使用libtomcrypt库进行RSA公钥生成.但是我无法使用Contiki OS在Cooja中加载库.
I am trying to work on RSA public key generation using libtomcrypt library for my school project. But I am unable to load the library in Cooja using Contiki OS.
我试图将所需的文件编译为目标文件,并将其加载到 .csc
文件中.
I tried to compile the file I need into an object file and load it in .csc
file.
这是我收到的错误消息:
This is the error message I got:

这是我试图用来将目标文件(rsa_get_size.o)添加到Cooja模拟脚本的 mote
部分中的代码.
This is the code I tried to use to add the object file (rsa_get_size.o) into the mote
section in the Cooja simulation script.

推荐答案
Contiki使用基于GNU make的系统.每个应用程序都有一个 Makefile
.要将其他文件添加到您的应用程序,请更改 Makefile
.
Contiki uses GNU make based system. There is a Makefile
for each application. To add extra files to your application, change the Makefile
.
如果只是一个文件,则需要添加:
If it's just one file you need to add:
PROJECT_SOURCEFILES += rsa_get_size.c
如果它是 .c
文件的整个目录,则假设应用程序文件夹中的 tomcrypt
:
If it's a whole directory of .c
files, let's say tomcrypt
in the application's folder:
MODULES += ./tomcrypt
