Source: odc
Version: 1.5.0-1
Tags: patch upstream
User: [email protected]
Usertags: ftcbfs
odc fails to cross build from source, because the upstream
CMakeLists.txt tries really hard to not build on 32bit platforms. It
verifies that sizeof(long) and sizeof(double) are 64bit in three
different ways, two of which require running a program. Running a
compiled program is what really does not work at all during cross
compilation, so those checks fail. I propose removing the redundant
checks and only leaving the check_type_size ones, because they should be
sufficient to ensure the property and they work with cross compilation.
I'm attaching a patch for your convenience.
Applying this patch will not make odc cross buildable. I've filed a
separate bug against dh-fortran-mod about another problem. Still close
this bug when addressing the cmake checks.
