# <https://bugzilla.altlinux.org/show_bug.cgi?id=31576>:
# maybe this bug requires more investigation to understand
# who goes crazy: a GHC lib or glibc,
# but now we simply work-around it:
Requires: glibc-gconv-modules

# The installed Haskell libs will be processed:
Requires(pre,postun): haskell-filetrigger >= 0.0.5-alt3
# <https://www.altlinux.org/RPM_Macros_Packaging_Policy>:
Requires: rpm-build-haskell >= 1.4.4-alt1
# (rpm-build-haskell-1-alt26 has been adapted to allow builds
# of Haskell modules without ghcN.N.N-common.)

# For ghc-pkg with rpath running during install, see:
# https://www.altlinux.org/Hasher/FAQ
# https://lists.altlinux.org/pipermail/devel/2018-April/204171.html
# Not needed after rebuild with separate single directory for shared libraries
BuildRequires: /proc

# Bootstrap with the previous version

# Generally, this could work with APT, after the "ghc" pseudo-package
# is brought back through Provides (allowing to rebuild this package in
# different environments):
#
# <https://ghc.haskell.org/trac/ghc/wiki/Building/Preparation/Tools>:
# In general, we support building with the previous 2 major releases, e.g.:
#BuildPreReq: ghc >= 7.2
# Newer GHC may be incompatible with the code of the current GHC:
#BuildPreReq: ghc <= %version

%description
Haskell is a standard lazy functional programming language; the
current language version is Haskell 98, agreed in December 1998.

GHC is a state-of-the-art programming suite for Haskell.  Included is
an optimising compiler generating good code for a variety of
platforms, together with an interactive system for convenient, quick
development.  The distribution includes space and time profiling
facilities, a large collection of libraries, and support for various
language extensions, including concurrency, exceptions, and foreign
language interfaces (C, C++, whatever).

A wide variety of Haskell related resources (tutorials, libraries,
specifications, documentation, compilers, interpreters, references,
contact information, links to research groups) are available from the
Haskell home page at <http://www.haskell.org/>.

%description common
Install this package to select %version as the default version
of Glasgow Haskell Compiler.

It will provide the common names for the GHC executables
(like unversioned /usr/bin/ghc).

And it will make rpm-build-haskell use this version of GHC for
building other Haskell packages
(if their .spec refers to %%ghc_version and %%_ghclibdir).

#   interpret the argument as a relative path; however, we have to include the
#   leading / again in the final file list (otherwise, rpm complains)
# * isn't there an easier way to do all this?
