我尝试happstack-server-tls在 Arch Linux (3.12.9) 上通过 cabal 安装软件包,但收到此错误:

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 ):

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crypto++通过 pacman 安装了。但这对我没有帮助。

我什至试过这个:

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

但仍然没有运气。

我检查了 crypto++ lib 是否适用于这个 test.cpp 文件:

#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;
}

并用g++ -g3 -ggdb -O0 -Wall -Wextra -Wno-unused -o test test.cpp -lcryptopp -pthreadtest.cpp 编译好。

然后我试着

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

但同样,仍然没有运气。

有人遇到过这个问题吗?它有什么解决办法吗?

运行cabal unpack happstack-server-tls以获取并解压缩本地目录中的源代码。然后编辑happstack-server-tls.cabal并尝试删除这些行:

if !os(darwin)
    Extra-Libraries: cryptopp
