Wrong build environment with makepkg
I am the maintainer of the
weex
package. I've encountered a strange issue. If I make the package with
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 :(

Re: Wrong build environment with makepkg
config.log from the failed configure will tell you.
Thanks!

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

Re: Wrong build environment with makepkg
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.

Re: Wrong build environment with makepkg
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

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
package() {
cd "$pkgname-$pkgver"
make DESTDIR="$pkgdir" install
