Building Error - undefined reference to `pcre_*'

[D3vil0p3r]

I am building bulk_extractor in Arch Linux by the following PKGBUILD:

pkgname=bulk-extractor
pkgver=2333.6a7da28
pkgrel=1
groups=('athena' 'athena-forensic' 'athena-misc')
pkgdesc='Bulk Email and URL extraction tool.'
arch=('x86_64')
url='https://github.com/simsong/bulk_extractor'
license=('GPL')
depends=('tre' 'flex' 'java-environment' 'openssl' 'exiv2' 'afflib' 'libewf' 'libxml2' 'zlib'
         'ncurses5-compat-libs' 're2')
makedepends=('git' 'autoconf' 'automake')
source=("git+https://github.com/simsong/${pkgname//-/_}.git")
sha512sums=('SKIP')

pkgver() {
  cd "${pkgname//-/_}"

  echo $(git rev-list --count HEAD).$(git rev-parse --short HEAD)
}

prepare() {
  cd ${pkgname//-/_}

  git submodule update --recursive --remote

  #sed -i 's|`dirname $0`|/usr/share/bulk-extractor|' java_gui/BEViewer

  sh bootstrap.sh
}

build() {
  cd ${pkgname//-/_}

  ./configure --prefix=/usr --sysconfdir=/etc

  make

  #make -C java_gui
}

package() {
  cd ${pkgname//-/_}

  install -dm 755 "$pkgdir/usr/share/$pkgname"

  make DESTDIR="$pkgdir" install

  #install -m 644 java_gui/BEViewer.jar "$pkgdir/usr/share/$pkgname"
  #install -m 755 java_gui/BEViewer "$pkgdir/usr/bin"
}

During the building, I get the following error:

Probably because on building flags there is not -lpcre flag. @simsong can you add it please?

[simsong]

Hi. Why are you bundling the git repo and not the release?

It should be added in configure.ac. I'm trying to add on it:

## pcre lib usage
AC_CHECK_LIB([pcre])

but, during the ./configure I don't still see -lpcre in the output in "LIBS=` variable.

[D3vil0p3r]

Oh... I saw the solution I proposed fixed the issue... Here the PR: https://github.com/simsong/bulk_extractor/pull/467

UPDATE: in reality, not needed. I added pcre dependency and seems to work.
