- Lowercase all commands
- Unify indent to 2 spaces
- Remove spaces around brackets
- Remove repitition of condition in else(...) and endif(...)
Note: (re-)running CMake did not change the content of the generated files
* Problem: No CI for mingw64
Adding CI support for mingw64 to appveyor.yml
Reason: To help address the issue:
Several checks fail under 64-bit MinGW on Windows when running make check #3185
* Problem: Docs do not build with mingw64, dll already in right place
Turning off WITH_DOC for mingw64
Removing copy command for mingw64 and cygwin64 (it now seems to be directly built in "bin" directoy)
Solution: Use cmake's libdir variable to ensure that the pkgconfig file
ends up in the correct lib/lib64 directory. This matches the autotools
behaviour.
Solution: ignore tautological-constant-compare warnings, as they
might be useless on 64 bit but they are not on 32 bit where sizeof
size_t != sizeof uint64_t
Problem: When building libzmq with CMake, the installed libzmq.dylib
has a relative install name (otool -D libzmq.dylib) on MacOS. This
is a regression against building via autotools which sets an
absolute install name. Effectively, the CMake built libzmq.dylib
is rendered useless if installed in non-system directories and
used in environments without explicit DYLD_LIBRARY_PATH mgmt. For
example running any of the installed executables currently fails:
$ /some_install_prefix/bin/inproc_lat
dyld: Library not loaded: libzmq.5.dylib
Referenced from: /some_install_prefix/bin/inproc_lat
Reason: image not found
Trace/BPT trap: 5
Solution: Best practice is to install relocatable dylibs.
On MacOS this means setting an install name with a special prefix,
e.g. @rpath/libzmq.dylib, and adding the relevant search paths
to the embedded rpath list. In this patch the necessary CMake options
are added to generate the desired relocatable dylibs. Find more
information on: https://cmake.org/Wiki/CMake_RPATH_handling.
Solution: remove objects optimisation in library build (similar to #2860)
and set PUBLIC compile definitions on all static builds instead of MSVC
only.
Solution: change case of `WinSock2.h Iphlpapi.h Rpc.h` to match the
files on disk. This is only noticeable when cross-compiling from a
case-sensitive system so wouldn't get picked up in MSVC or mingw
builds running on a windows machine.
MSDN uses capitalised versions in prose and lowercase in code examples:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms737629(v=vs.85).aspxFixes#2978, the missing library message is a little misleading.
This fixes an error with the cmake install configuration, which
attempted an invalid copy of a .pdb file on windows, when the
BUILD_SHARED option is disabled.
Solution: revert the objects optimisation, and go back to building
everything twice on Windows, as the static builds needs different
preprocessor definitions from the shared one, so the objects have to be
rebuilt.
Keep the optimisation for all the other platforms.
Fixes#2858
