Question

我在aarch64上使用Crypto ++，在编译使用cryptopp-7.0.0的二进制文件时遇到一个问题，我面对的唯一链接问题与def scroll(): xx = 10 while True: browser.execute_script("window.scrollTo(0, {})".format(xx)) xx += 10有关，所有其他类都运行良好，这是程序本身，它实际上是一个隔离问题的基本程序：

RSAFunction

尝试使用此命令进行编译时：

#include "cryptopp/rsa.h"
using CryptoPP::RSA;

#include <string.h>
using std::string;

#include <unistd.h>

int main(void)
{
    RSA::PublicKey publicKey;
    return 0;
}

我遇到了这些错误：

~$ toolchain/bin/aarch64-libreelec-linux-gnueabi-g++ cryptopptestfile.cpp -o crypttest -L/toolchain/usr/lib -lcryptopp

这仅与：

感谢帮助。

以下是编译标志：

cryptopp::RSAFunction(s)

g ++版本：

arch64-libreelec-linux-gnueabi-g++ -march=armv8-a+crc+fp+simd -mabi=lp64 -Wno-psabi -mcpu=cortex-a53+crc+fp+simd -fomit-frame-pointer -Wall -pipe -Os -flto -ffat-lto-objects -fPIC -pipe -c rsa.cpp

已确定问题，这是因为此编译标志：

idx = ((old['Pub Date'] == new['Pub Date'])
       & (old['Forecast Time'] == new['Forecast Time'])
       & (old['Forecast Date'] == new['Forecast Date'])
       & (old['State'] == new['State'])

if ~np.all(idx==False):
    # now concatenate the new data onto the old dataframe.
    old = pd.concat([old, new.loc[~idx, :], axis=0)

我删除此编译标志后，一切正常，请注意激活此标志：

-flto

使用从6.0.0到8.0.0版本测试的RSAFunction时，此标志会断开链接器

无法链接对CryptoPP :: RSAFunction的VTT的未定义引用
