Rationale follows. If neither python nor python3 is pre-installed in the build system, cross-compilation fails: checking for swig... no configure: WARNING: "Swig not found - python bindings will not be made" checking whether to create python bindings... testing checking for python... no checking for python2... no checking for python3... no checking for python3.5... no checking for python3.4... no checking for python3.3... no checking for python3.2... no checking for python3.1... no checking for python3.0... no checking for python2.7... no checking for python2.6... no checking for python2.5... no checking for python2.4... no checking for python2.3... no checking for python2.2... no checking for python2.1... no checking for python2.0... no configure: error: no suitable Python interpreter found >>> ERROR: libcap-ng: build failed This error is printed by AM_PATH_PYTHON at ./configure.ac:125 which assumes lack of python is fatal when invoked without the third arg. Also note the swig warning. After replacing 'makedepends="python3 $depends_dev"' at APKBUILD:10 with 'makedepends_build="python3"', cross-configure succeeds saying python is of no use anyway: checking whether to create python bindings... testing checking for python... no checking for python2... no checking for python3... /usr/bin/python3 checking for python version... 3.6 checking for python platform... linux checking for python script directory... ${prefix}/lib/python3.6/site-packages checking for python extension module directory... ${exec_prefix}/lib/python3.6/site-packages configure: WARNING: "Python headers not found - python bindings will not be made" checking whether to create python3 bindings... investigating checking for python3-config... no sh: yes: unknown operand Python3 bindings will NOT be built --- main/libcap-ng/APKBUILD | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-) diff --git a/main/libcap-ng/APKBUILD b/main/libcap-ng/APKBUILD index 69444c9248..857f971bf8 100644 --- a/main/libcap-ng/APKBUILD +++ b/main/libcap-ng/APKBUILD @@ -1,13 +1,13 @@ # Maintainer: Natanael Copa pkgname=libcap-ng pkgver=0.7.9 -pkgrel=0 +pkgrel=1 pkgdesc="POSIX capabilities library" url="http://people.redhat.com/sgrubb/libcap-ng/index.html" arch="all" license="GPL-2.0-or-later LGPL-2.1-or-later" depends_dev="linux-headers" -makedepends="python3 $depends_dev" +makedepends_build="" makedepends_host="$depends_dev" subpackages="$pkgname-dev $pkgname-doc $pkgname-utils" source="https://people.redhat.com/sgrubb/libcap-ng/libcap-ng-$pkgver.tar.gz @@ -17,13 +17,16 @@ builddir="$srcdir/$pkgname-$pkgver" build() { cd "$builddir" + ac_cv_prog_swig_found=no \ ./configure \ --build=$CBUILD \ --host=$CHOST \ --prefix=/usr \ --sysconfdir=/etc \ --mandir=/usr/share/man \ - --infodir=/usr/share/info + --infodir=/usr/share/info \ + --without-python \ + --without-python3 make } -- 2.20.1 --- Unsubscribe: alpine-aports+unsubscribe@lists.alpinelinux.org Help: alpine-aports+help@lists.alpinelinux.org ---
