Description of problem: After adding CFLAGS to %cabal_configure build.log's now include + ./Setup configure --prefix=/usr --libdir=/usr/lib64 --docdir=/usr/share/doc/cabal-rpm '--libsubdir=$compiler/$pkgid' '--datasubdir=$pkgid' --ghc --enable-executable-dynamic '--ghc-options= -optc-O2 -optc-g -optc-pipe -optc-Wall -optc-Werror=format-security -optc-Wp,-D_FORTIFY_SOURCE=2 -optc-fexceptions -optc-fstack-protector-strong -optc--param=ssp-buffer-size=4 -optc-grecord-gcc-switches -optc-m64 -optc-mtune=generic -optl-Wl,-z,relro' Configuring cabal-rpm-0.9.2... /tmp/18846.c: In function 'foo': /tmp/18846.c:1:1: warning: control reaches end of non-void function [-Wreturn-type] int foo() {} ^ This caused by -Wall and something in Cabal I guess. Grepping the Cabal source only shows up: ./Distribution/Simple/GHC.hs:362: hPutStrLn testchnd "int foo() { return 0; }" Version-Release number of selected component (if applicable): ghc-rpm-macros-1.2.17-1.fc21 ghc-rpm-macros-1.3.9-1.fc22 Steps to Reproduce: 1. build Fedora Haskell package Cabal-based package Actual results: : warning: control reaches end of non-void function [-Wreturn-type] : Expected results: no warning Additional info: Should probably report this upstream. It can be reproduced by: ./Setup configure --ghc-option=-optc-Wall
Looks like this is fixed with Cabal-1.18 (ghc-7.8.3+) but happens with ghc-7.6.3 Cabal.
Moving to F21 since this will not affect ghc-7.8.
