使用腳手架搭建我的haskell項目後,發生一些cabal故障。cabal build --ghc-options =「 - fforce-recomp -Wall -fno-code」失敗
我不認爲的問題與該插件(看起來更像一般的陰謀的問題),因爲我可以複製它從一個標準cabal init
開始。如果這個問題與SublimeHaskell有關,或者許多人似乎正在使用它,我會感到驚訝。
這裏是被生成的小集團文件(I簡化/縮短它一個位):
(聖項目沿產生一些示例性源文件)
name: test-holy
version: 0.1.0.0
build-type: Simple
cabal-version: >=1.10
library

, TestHoly.Coconut

cabal build
工作
以下命令不起作用:
$ cabal clean && cabal configure && cabal build --ghc-options="-fforce-recomp -Wall -fno-code"

據我所知,由於-fno-code
標誌(省略代碼生成)沒有生成目標文件,因此連接器失敗。這是預期的嗎?還是應該鏈接器沒有被調用?
爲什麼我運行那個cabal命令?
正如我前面所說:我使用SublimeText來編輯我的項目。它失敗的項目,聖生成以下消息小集團文件:
Build FAILED
REMAINING STDERR:
Warning: the following files would be used as linker inputs, but linking is not being done: dist/build/TestHoly.dyn_o dist/build/TestHoly/Swallow.dyn_o dist/build/TestHoly/Coconut.dyn_o
ghc: no input files
Usage: For basic information, try the `--help' option.
通過討論SublimeHaskell#158我接着NH2的建議,直接運行這個陰謀命令(因爲它是由SublimeHaskell使用的)。
我會很感激,如果有人可以在這個光!

不,如果你通過'-c'標誌GHC工作? – 2014-10-31 01:24:28
'cabal build --ghc-options =「 - c -fforce-recomp -Wall -fno-code」'給出同樣的問題。我通過將'--verbose'傳遞給cabal來檢查,並且在ghc命令中傳遞該標誌:'/ usr/bin/ghc --make -fbuilding-cabal-package ... -Wall -c -fforce-recomp - 牆-fno-code' – dvekeman 2014-11-01 11:54:14
你可以嘗試添加'-fwrite-interface'嗎? – 2015-09-17 09:59:42
