在Windows下安装glib时Cabal缺少对外部库的依赖

Question

我需要glib才能使threadscope正常工作。 但是我无法使用cabal安装它。 我尝试了cabal install glib但收到以下错误。 我什至尝试下载该库并在本地安装它，但收到相同的错误。

我在Windows上使用Cygwin。 我运行Cygwin安装程序以确保我缺少库。 我能够找到glib，gobject但找不到gthread。

    Gtk2HsSetup.hs:25:2:
         warning: #warning Setup.hs is guessing the version of Cabal. If compilation
     of Setup.hs fails use -DCABAL_VERSION_MINOR=x for Cabal version 1.x.0 when buil
    ding (prefixed by --ghc-option= when using the 'cabal' command)

    This problem can usually be solved by installing the system packages that
    provide these libraries (you may need the "-dev" versions). If the libraries
    are already installed but in a non-standard location then you can use the
    flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.

    glib-0.12.0 failed during the configure step. The exception was:
    ExitFailure 1

Answer 1

不久前，我在原始Wiki文章中写了一个关于如何安装Gtk2H的小勘误表。 这是链接http://progandprog.blogspot.com/2011/04/installing-gtk2hs-012-for-latest.html

我试图在这里描述所有步骤，希望对您有所帮助。

所有这些步骤都是通过最新的Gtk2H和Haskell平台安装完成的。 没有安装Cygwin和MinGW。

看来您需要先安装gtk2hs。

这是gtk2hs存储库中gtk2hs的Windows安装说明 （因此，我认为它们是最新且最新的）。

特别是，我认为您需要遵循以下几点：

Building on Windows
--------------------

Installation on Windows is nearly as easy as on Unix platforms. However, you
need to download the pre-compiled binary libraries of Gtk+ and all it's
dependent libraries. Point your browser to

http://www.gtk.org/download-windows.html

and download one of the "All-in-one bundles". Note that you do *not* need to
install MinGW nor MSys (but it does not hurt if they are installed on your
system). Install the binaries by unpacking them into a directory without
spaces. Again, this is very important:

*** Do not install the binaries into a directory with embedded spaces. ***

Ensure that the /bin directory is added to your %PATH%. You can ensure that
everything is installed correctly if you can say

pkg-config --cflags gtk+-2.0

and you see some compiler flags that contain the path into which you have
installed the binary bundle. We had reports that the binaries containing version 2.22 do not work and that the version 2.16 gives the following errors when running cabal:

setup.exe: gtk-0.12.0: library-dirs: c:/.../dist/win64/libpng-1.4.3-1/lib doesn't exist or isn't a directory

This problem can be worked around by creating said directory and copying libpng into it. Any further feedback regarding the installation of the binary packages is welcome.

You may now install the cabal packages of Gtk2Hs into any directory you like
(including one that contains embedded spaces). Note that cabal installs the
tools necessary to build into something like

C:\Documents and Settings\%user%\Application Data\cabal\bin

Make sure that this path is also in your %PATH% variable!

ghci and Gtk2Hs on Windows

Due to the way cabal registers packages with ghc, it is quite difficult to
perform the renaming of libraries which is necessary for the binary Windows
bundle to work. As a consequence, the cabal package can do this renaming only
with Cabal 1.8 (shipped with ghc 6.12). If you use ghc 6.10 or earlier, you
need to upgrade your Cabal system to 1.8 if you want to build Gtk2Hs with ghci
support. Note that it is always possible to build executables on Windows.

完成这项工作后，您应该能够简单地：

cabal install gtk gtk2hs-buildtools glib

我不确定这个答案，但是至少在大多数Linux发行版中，有单独的库和“ dev”库软件包。 裸露的库包仅包含该库-即，仅在构建需要该程序的库时才需要使用该库-而“ dev”版本包含C头文件以及构建使用该库的程序所必需的其他内容图书馆。 Cygwin有类似的东西吗？ 如果是这样，您是否安装了gobject，gthread，glib等的“开发”版本？
