我是Yesod的新手,无法静态构建Yesod,因此可以部署到Heroku。
我已更改默认的.cabal文件以反映静态编译
if flag(production)
cpp-options: -DPRODUCTION
ghc-options: -Wall -threaded -O2 -static -optl-static
else
ghc-options: -Wall -threaded -O0
而且它不再构建。我收到一堆警告,然后是许多未定义的引用,如下所示:

如果我仅使用just进行编译,-static而没有进行-optl-static
任何编译,则一切正常,但是当尝试在Heroku上启动时,应用程序崩溃。
2011-12-28T01:20:51+00:00 heroku[web.1]: Starting process with command

我尝试按照此处的建议将libgmp.so.10添加到LD_LIBRARY_PATH
,然后出现以下错误:
2011-12-28T01:31:23+00:00 app[web.1]: ./dist/build/personal-website/

似乎我要针对的libc版本不同。我也尝试像对libgmp一样将libc添加到库批次中,但是当应用程序在Heroku端启动时,这会导致分段错误。
在我的PC上一切正常。我正在使用ghc 7.0.3运行64位archlinux。
Yesod官方博客上的博客文章看起来很简单,但是我对此感到困惑。谁有想法?如果有一种方法可以在 不进行 静态构建的情况下使它正常工作,那么我也对此持开放态度。

每个Employed Russians答案我做了以下修复。
首先在lib项目目录下创建一个新目录,然后将缺少的共享库复制到其中。您可以通过运行获取此信息ldd
path/to/executable,并heroku run ldd path/to/executable和比较输出。
然后我这样做了heroku config:add LD_LIBRARY_PATH=./lib,当启动应用程序时,动态链接器将在新的lib目录中查找库。
最后,我创建了一个ubuntu 11.10虚拟机,并从那里构建并部署到Heroku,它具有足够老的glibc,可以在Heroku主机上运行。
编辑:从那以后我就在Yesod Wiki上写了一个教程
