Cryptopp外部库依赖

cryptopp foreign library dependency

本文关键字：依赖 外部 Cryptopp      更新时间：2023-10-16

我尝试在Arch Linux(3.12.9)上通过cabal安装happstack-server-tls包，但得到这个错误:

Resolving dependencies...
Configuring happstack-server-tls-7.1.0...
Failed to install happstack-server-tls-7.1.0
Last 10 lines of the build log ( /home/boris/.cabal/logs/happstack-server-tls-7.1.0.log ):
Configuring happstack-server-tls-7.1.0...
/bin/sh: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)
setup-Cabal-1.16.0-x86_64-linux-ghc-7.6.3: Missing dependency on a foreign
library:
* Missing C library: cryptopp
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.
cabal: Error: some packages failed to install:
happstack-server-tls-7.1.0 failed during the configure step. The exception
was:
ExitFailure 1

第一次看到这个错误信息后，我已经通过pacman安装了crypto++。但它没有帮助我。

我甚至试过这个:

$ whereis libcryptopp.a                                                                                           
libcryptopp: /usr/lib/libcryptopp.so
$ cabal install happstack-server-tls --extra-include-dirs=/usr/lib/ --extra-lib-dirs=/usr/lib/

但还是没有运气。

我检查了，如果crypto++ lib与这个test.cpp文件一起工作:

#include <iostream>
using std::cout;
using std::endl;
#include "cryptopp/integer.h"
using CryptoPP::Integer;
int main( int, char** ) {
    Integer i;
    cout << "i: " << i << endl;
    return 0;
}

并与g++ -g3 -ggdb -O0 -Wall -Wextra -Wno-unused -o test test.cpp -lcryptopp -pthread测试。cpp编译良好。

然后我试着

$ cd /usr/lib
$ g++ -fpic -nostartfiles -nostdlib -shared libcryptopp.so -o libcryptopp.dylib

但是，还是没有运气。

有人遇到过这个问题吗?有解决方案吗?

运行cabal unpack happstack-server-tls在本地目录中获取并解包源代码。然后编辑happstack-server-tls.cabal并尝试删除这些行:

if !os(darwin)
    Extra-Libraries: cryptopp
