Package: aptitude Version: 0.7.4-1 Hi,
While checking why gnudatalanguage has "BD-Uninstallable" on most architectures, I tried to install all build-dependencies locally. First I checked what's missing in the extracted source package: $ dpkg-checkbuilddeps dpkg-checkbuilddeps: error: Unmet build dependencies: chrpath libeigen3-dev libgsl0-dev libgraphicsmagick++1-dev libplplot-dev (>= 5.10.0+dfsg-1~) | libplplot-dev (<= 5.10) Looked reasonable. Then I tried to install those packages as follows: # aptitude build-dep gnudatalanguage Unable to satisfy the build-depends: Build-Depends: libncurses-dev. Unable to satisfy the build-depends: Build-Depends: libplplot-dev ( 5.10.0+dfsg-1~) | libplplot-dev ( 5.10). Unable to satisfy the build-depends: Build-Depends: libncurses-dev. Unable to satisfy the build-depends: Build-Depends: libplplot-dev ( 5.10.0+dfsg-1~) | libplplot-dev ( 5.10). The following NEW packages will be installed: chrpath libeigen3-dev libgraphicsmagick++1-dev libgraphicsmagick1-dev{a} libgsl0-dev 0 packages upgraded, 5 newly installed, 0 to remove and 2 not upgraded. Need to get 3,185 kB of archives. After unpacking 20.2 MB will be used. Do you want to continue? [Y/n/?] Please note the missing ">=" and "<=" in the error messages (compared to the dpkg-checkbuilddeps output) while the space behind them is there. Also the trailing dot at the end of all these error messages looks wrong -- but is probably not a technical issue, just a question of grammar. The following are the full build-dependencies from apt-cache showsrc gnudatalanguage on the same machine: Build-Depends: chrpath, cmake, debhelper (>= 9~), dpkg-dev (>= 1.16.1~), libantlr-dev, libeigen3-dev, libfftw3-dev, libgrib-api-dev, libgsl0-dev, libhdf4-alt-dev, libhdf5-dev | libhdf5-serial-dev, libgraphicsmagick++1-dev, libncurses-dev, libnetcdf-dev, libplplot-dev (>= 5.10.0+dfsg-1~) | libplplot-dev (<= 5.10), libreadline-dev, libudunits2-dev, libwxgtk3.0-dev, pslib-dev, python-all-dev, python-numpy, xauth, xvfb, zlib1g-dev libncurses-dev is btw. a virtual package while libplplot-dev isn't. So the reason for the error message about libncurses-dev is https://bugs.debian.org/509100 (aptitude: build-dep fails when a virtual package is needed), but the fact that there is even an error message for libplplot-dev is maybe related to the fact that the comparison operator is not shown. JFTR what apt-get would do (afterwards): # apt-get build-dep gnudatalanguage Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: libcsiro0 libplplot-c++11 libplplot-dev libplplot-fortran10 libplplot12 libqhull-dev libqsastime-dev libqsastime0 plplot12-driver-qt plplot12-driver-wxwidgets 0 upgraded, 10 newly installed, 0 to remove and 2 not upgraded.
