Wrong build environment with makepkg

aaronmueller · 2014-07-13 09:43:11

I am the maintainer of the weex package. I've encountered a strange issue. If I make the package with

$ makepkg

the configure step breaks with

checking for regex.h... no
checking for gnuregex.h... (cached) no
checking for regex.h... (cached) no
configure: error: GNU regex library is not installed.

If I run the configure-step manually (as a normal user), the configure script can find the regex.h file (because it is here: /usr/include/regex.h)

So, why can't find makepkg the includes here? I've tried to put the header file in the source folder (see PKGBUILD), but this does not work either :(

config.log from the failed configure will tell you.

Thanks!

makepkg:

Seems the /lib/cpp macro does not work? But why?

Not enough context. Please post the whole log from the failed configure.

I'll note that /lib/cpp is an old symlink that no longer exists in Arch.

Problem seems to be that default Arch CPPFLAGS includes -D_FORTIFY_SOURCE=2 which trips up the check. The build system for weex is absolutely ancient (which is why it references /lib/cpp), but autoreconf will fail because, again, the build system is ancient and doesn't conform to modern autotools setups.

You can work around this in build by unsetting CPPFLAGS and moving -D_FORTIFY_SOURCE=2 to CFLAGS. Here's a better PKGBUILD that fixes a lot of other issues:

pkgname=weex
pkgver=2.6.1.5
pkgrel=5
pkgdesc="A non-interactive FTP client for updating web pages"
arch=(i686 x86_64)
license=("GPL")
source=("http://downloads.sourceforge.net/sourceforge/$pkgname/$pkgname-$pkgver.tar.gz"
        "http://git.sv.gnu.org/gitweb/?p=gnulib.git;a=blob_plain;f=lib/regex.h"
        "weex-2.6.1.5-formatstring.patch"
        "weex-2.6.1.5-va_list.patch")
md5sums=("c10192608ab9f715c4c1ea63cf6ad2da"
         "63dc5065aa90e787153804229e7da1c2"
         "a12d955c5a4d6b059395a0da22942114"
         "522552e03b82ab5669fd21c558290691")
url="http://weex.sourceforge.net/"

prepare() {
  cd "$pkgname-$pkgver"

  patch -Np0 -i ../weex-$pkgver-formatstring.patch
  [[ $CARCH == x86_64 ]] && patch -Np0 -i ../weex-$pkgver-va_list.patch
}

build() {
  cd "$pkgname-$pkgver"

  # work around problems in ancient autotools installation
  unset CPPFLAGS
  CFLAGS+=' -D_FORTIFY_SOURCE=2'

  ./configure --prefix=/usr
  make
}

package() {
  cd "$pkgname-$pkgver"

  make DESTDIR="$pkgdir" install
}

Thanks a lot! Works now!
