AUR gmp4 PKGBUILD fixed

gmp4.PKGBUILD

pkgname=gmp4

pkgrel=2
pkgdesc="Legacy version of gmp. Provides 'libgmp.so.3'."

prepare(){
  cd "${srcdir}/gmp-${pkgver}"
  #Put gmp.h in the same folder as gmpxx.h
  sed -i 's/$(exec_prefix)\/include/$\(includedir\)/' Makefile.in
}

build() { 
  cd "${srcdir}/gmp-${pkgver}"
  ./configure --prefix=/usr --enable-cxx
  make DESTDIR="${srcdir}/installed" install || return 1
}

package() {
  mkdir -p "${pkgdir}/usr/lib"
  cp -a "${srcdir}/installed/usr/lib/"libgmp.so.3* "${pkgdir}/usr/lib/" || return 1
}

Seems the dependencies must be corrected:

$ namcap -i /var/cache/pacman/pkg/gmp4-4.3.2-2-x86_64.pkg.tar.xz 
gmp4 I: Link-level dependence (glibc) in file ['usr/lib/libc.so.6']
gmp4 I: Symlink (usr/lib/libgmp.so.3) found that points to libgmp.so.3.5.2
gmp4 W: Dependency included and not needed ('gcc-libs')
gmp4 W: Dependency included and not needed ('sh')
gmp4 I: Dependency covered by dependencies from link dependence (linux-api-headers)
gmp4 I: Dependency covered by dependencies from link dependence (tzdata)
gmp4 I: Dependency covered by dependencies from link dependence (filesystem)
gmp4 I: Dependency covered by dependencies from link dependence (iana-etc)
gmp4 I: Depends as namcap sees them: depends=(glibc)

And add x86_64 arch.
