我尝试编译 opendcp , 但发生错误。
$ make

这对我来说似乎是 openssl 问题,所以我尝试对此进行测试:
$ cat testBIGNUM.cpp
#include <openssl/bn.h>
int main(){
BIGNUM bn;
}
$ g++ testBIGNUM.cpp
testBIGNUM.cpp: In function ‘int main()’:
testBIGNUM.cpp:4:9: error: aggregate ‘BIGNUM bn’ has incomplete type and cannot be defined
BIGNUM bn;
^~
我的 openssl 版本是 1.1.0d-2,我不知道如何修复它。
最佳答案
OpenSSL 1.0.2 和 OpenSSL 1.1.0 之间有很大的变化,它们不是完全源兼容的。特别是 1.0.2 头文件中的许多数据结构现在是不透明的。使用 OpenSSL 的应用程序需要进行一些小的更改才能兼容。
如果是 BIGNUM,你需要这样做:
#include <openssl/bn.h>
int main() {
BIGNUM *bn;
bn = BN_new();
...
BN_free(bn);
return 0;
}
对于 opendcp,答案可能是降级到 OpenSSL 1.0.2。
关于c++ - 聚合 ‘BIGNUM foo’ 类型不完整,无法定义,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/42292027/
