Special Update/Build Instructions¶

csdp is an autotool’ed version of CSDP, see https://projects.coin-or.org/Csdp, developed in its own repository at https://github.com/dimpase/csdp.

To update to a new version, you need to bump the version number in configure.ac and rerun autotools (autoreconf -fiv). Any changes should be merged to the upstream repo.

The build is done with NOSHORTS variable defined; this makes it compatible with packages, where NOSHORTS must be defined, e.g. https://github.com/dimpase/pycsdp; also the Sage Cython interface needs NOSHORTS defined.

Detailed steps to build the spkg are as follows. You need

git
autotools and libtool (the full autohell suite, version at least 2.67)

With these ready:

./spkg-src
copy the resulting csdp-<version>.tar.gz to SAGE_ROOT/upstream, or somewhere else appropriate

Type¶

optional

Version Information¶

package-version.txt:

6.2.p1

Equivalent System Packages¶

Arch Linux

$ sudo pacman -S coin-or-csdp

Fedora/Redhat/CentOS

$ sudo yum install csdp csdp-devel csdp-tools

See https://repology.org/project/coin-or-csdp/versions, https://repology.org/project/csdp/versions

However, these system packages will not be used for building Sage because spkg-configure.m4 has not been written for this package; see Issue #27330 for more information.
