It builds for the intersection of versions known in \&\f(CW\*(C`debian/pgversions\*(C'\fR (versions supported by the package) and in \&\f(CW\*(C`/usr/share/postgresql\-common/supported\-versions\*(C'\fR (versions supported in this release). .SH "USAGE" .IX Header "USAGE" Packages using \fBpg_buildext\fR should be prepared to build binaries for PostgreSQL versions that are not present in Debian unstable, e.g. for older releases when building backports for Debian (old)stable (possibly including backports of newer PostgreSQL releases), or for all PostgreSQL releases when the package is built for \fBapt.postgresql.org\fR. .PP As the set of binary packages depends on the target PostgreSQL versions, \&\f(CW\*(C`debian/control\*(C'\fR is generated from a template in \f(CW\*(C`debian/control.in\*(C'\fR when \&\fBpg_buildext updatecontrol\fR is run. Occurrences of \fB\s-1PGVERSION\s0\fR in package sections are replaced by the target PostgreSQL version. Include \&\f(CW\*(C`/usr/share/postgresql\-common/pgxs_debian_control.mk\*(C'\fR in \f(CW\*(C`debian/rules\*(C'\fR to run a check at build time if updating debian/control is required. .PP As \fBpg_buildext\fR invokes \fBmake\fR for the \fBbuild\fR, \fBinstall\fR, and \fBclean\fR actions, invocations from \f(CW\*(C`debian/rules\*(C'\fR (which is a makefile) should be prefixed with \fB+\fR so the sub-makes can talk with the make jobserver. .PP Many extensions support \fBmake installcheck\fR testing using \fBpg_regress\fR. As this needs the package to be installed, it cannot be run at build time. Instead, the tests should be run using \fBautopkgtest\fR from \f(CW\*(C`debian/tests/*\*(C'\fR. .SH "OPTIONS" .IX Header "OPTIONS" .IP "\fB\-cio\fR \fIarg\fR" 4 .IX Item "-cio arg" .PD 0 .IP "\fB\-s\fR" 4 .IX Item "-s" .PD Passed to \fBpg_virtualenv\fR when running \fBinstallcheck\fR. .SH "ACTIONS" .IX Header "ACTIONS" Most actions expect a directory name where to build the sources. It will get created for you if it does not exist. If the \fIbuild-dir\fR contains a \f(CW%v\fR sign, it will get replaced by the specific version of PostgreSQL being built against. (Usually this parameter is \f(CW\*(C`build\-%v\*(C'\fR.) .IP "\fBsupported-versions\fR" 4 .IX Item "supported-versions" Print effective list of supported versions, i.e. the intersection of the sets of versions supported by the system and the package. .IP "\fBcheckcontrol\fR" 4 .IX Item "checkcontrol" Check if \f(CW\*(C`debian/control\*(C'\fR needs updating from \f(CW\*(C`debian/control.in\*(C'\fR. This is invoked from \f(CW\*(C`/usr/share/postgresql\-common/pgxs_debian_control.mk\*(C'\fR. When building for a \fBbackports\fR or \fBpgdg\fR suite as determined by \&\f(CW\*(C`debian/changelog\*(C'\fR, this action also updates the control file. Otherwise, \&\fBupdatecontrol\fR needs to be run manually. .IP "\fBupdatecontrol\fR" 4 .IX Item "updatecontrol" Update \f(CW\*(C`debian/control\*(C'\fR from \f(CW\*(C`debian/control.in\*(C'\fR. .IP "\fBconfigure\fR \fIbuild-dir\fR [\fIextra-configure-options\fR]" 4 .IX Item "configure build-dir [extra-configure-options]" For every supported version, call \fB../configure\fR from the \fIbuild-dir\fR directory. (Most PostgreSQL extensions do not have a configure script.) .IP "\fBbuild\fR \fIbuild-dir\fR [\fIextra-cflags\fR]" 4 .IX Item "build build-dir [extra-cflags]" Build the extension in the \fIbuild-dir\fR directory. .IP "\fBinstall\fR \fIbuild-dir\fR \fIpackage-pattern\fR" 4 .IX Item "install build-dir package-pattern" Invoke \fBmake install\fR from the \fIbuild-dir\fR directory. The third parameter specifies the package name to use. Most packages use \fBpostgresql\-%v\-pkgname\fR. Make will be called with DESTDIR="$(\s-1CURDIR\s0)/debian/\fIpackage\fR". .IP "\fBclean\fR \fIbuild-dir\fR" 4 .IX Item "clean build-dir" Clean the build directory. .IP "\fBloop\fR \fIpackage-pattern\fR" 4 .IX Item "loop package-pattern" As a variant to calling \fBbuild\fR and \fBinstall\fR separately for \s-1VPATH\s0 builds, loop over the supported PostgreSQL versions in the top source directory. This should be used if the package does not support \s-1VPATH\s0 builds. As it also invokes \&\fBmake install\fR, it should be placed were installation happens in debian/rules, rather than where build would normally be called. .IP "\fBinstallcheck\fR [\fIbuild-dir\fR]" 4 .IX Item "installcheck [build-dir]" Use \fBpg_virtualenv make installcheck\fR to run the extension regression tests. This is meant to be run from \f(CW\*(C`debian/tests/control\*(C'\fR using \fBautopkgtest\fR. If \&\fIbuild-dir\fR is omitted, the top source directory is used. .PP Sometimes it is desirable to run extra code per version before invoking the action, in that case the loop over supported versions needs to be in the calling script. To facilitate this mode, actions can also be called as \&\fIaction\fR\fB\-\fR\fIversion\fR. See the installcheck example below. .SH "SUPPORTED VERSIONS" .IX Header "SUPPORTED VERSIONS" \&\fBpg_buildext\fR reads \f(CW\*(C`debian/pgversions\*(C'\fR to decide which PostgreSQL to build modules/extensions for. This file contains one PostgreSQL version number per line, in the following formats: .IP "\fBall\fR" 4 .IX Item "all" Support all versions. This is recommended unless there are known incompatibilities. .IP "\fIX.Y\fR" 4 .IX Item "X.Y" Support this version. .IP "\fIX.Y\fR\fB+\fR" 4 .IX Item "X.Y+" Support this and all greater versions. .IP "\fB#\fR\fI...\fR" 4 .IX Item "#..." Comment. .PP For a version to be used, it must also be listed in the output of \&\f(CW\*(C`/usr/share/postgresql\-common/supported\-versions\*(C'\fR.
