【问题描述】：
我尝试在 Arch Linux (3.12.9) 上通过 cabal 安装 happstack-server-tls 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 ):
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
在第一次看到这个错误信息后，我已经通过 pacman 安装了crypto++。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/
但还是没有运气。
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 -pthread test.cpp 编译好。
然后我尝试了
$ 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？
