* MinGW: Update find_library to not find plain .dll filesBrad King2020-01-202-2/+2
| | | | | | | | Modern distributions of packages built with MinGW tools provide `.dll.a` import libraries. Prefer those instead of finding plain `.dll` files. This avoids accidentally finding unrelated Windows `.dll` files. Fixes: #20019

|/ / | | | | | | | | | | | | | | | | | | Starting with CUDA 10.2 the nvcc compiler has gained support to automatically forward unknown flags to the host compiler. This behavior is highly desired as projcts that mix CUDA, C, C++ run into situation where flags such as `-pthread` which aren't supported by nvcc, are being applied to all source files and therefore break CUDA compilation.

* | | Clang: Fall back to llvm-rc when rc is unavailableGregory Mitrano2019-08-141-0/+15
| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change modifies how CMAKE_RC_COMPILER is configured to improve the out-of-box experience for developers using Clang on Windows. The previous behavior was to require the user to explicitly specify the resource compiler when CMake was called. The new behavior is to automatically attempt to locate the MSVC rc binary and use that if it's found. If rc is not available, CMake will now fall back to Clang's llvm-rc binary. With this change in place, trivial C/C++ programs can be generated with Ninja and Clang on Windows without running into errors about a missing resource compiler. Fixes: #19318
* | Make CMAKE_LINK_LIBRARY_FILE_FLAG work like CMAKE_LINK_LIBRARY_FLAGBrad King2019-08-021-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The `CMAKE_LINK_LIBRARY_FILE_FLAG` variable is meant for linkers that want library file paths to be preceded by a flag. This is used only for OpenWatcom to add the `library` argument before library file paths. Refactor the approach to treat `CMAKE_LINK_LIBRARY_FILE_FLAG` as a command-line string fragment to add just before the library file path. This has two advantages: * `CMAKE_LINK_LIBRARY_FILE_FLAG` now works like `CMAKE_LINK_LIBRARY_FLAG`. * `CMAKE_LINK_LIBRARY_FILE_FLAG` can now be an attached flag whose value is the library file path. Technically this is a change in behavior, but this setting was created for internal use and should be rarely used outside of CMake itself. Fixes: #19541
* | Android: Use unified toolchain in NDK r19+Brad King2019-07-266-3/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The NDK build system now uses only a single toolchain in <ndk>/toolchains/llvm/prebuilt/<host> Its compilers are always `bin/{clang,clang++}` and its binutils are always `bin/<triple>-*`. It is a standalone toolchain: * The Anrdoid API level is specified at the end of `--target=`. * The standard library may be specified via `-stdlib=`. * No need to pass system includes or libraries explicitly. * No need to pass `--sysroot` or `-gcc-toolchain`. Teach CMake to recognize NDK versions that have a unified toolchain with its own sysroot and use the above approach. Fixes: #18739

* | AIX: Do not enable runtime linking by default anymoreBrad King2019-07-172-14/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've long created shared objects on AIX using the linker's `-G` option (also offered by the XL front-end). The `-G` option implies `-brtl` and enables runtime linking. This has been largely unnecessary because we provide all dependencies on the link line and both XL and GNU compilers offer builtin behavior to export symbols. Since commit 0f150b69d3 (AIX: Explicitly compute shared object exports for both XL and GNU, 2019-07-11) we compute exports explicitly and consistently. Therefore runtime linking is no longer necessary for shared objects. We've also long created executables on AIX using the linker's `-brtl` option to enable runtime linking in case they load plugins at runtime. Since commit 9f5c2040bf (AIX: Explicitly compute executable exports for both XL and GNU, 2019-07-12) and commit 2fa920c0cd (AIX: Create import library for executables with exports, 2019-07-16) we now provide the linker enough information to fully resolve symbols in plugins up front. Therefore runtime linking is no longer necessary for executables. Drop use of `-G` for creating shared objects and use the XL `-qmkshrobj` and GCC `-shared` options instead. Both invoke the linker with the `-bM:SRE -bnoentry` options to create a shared object without runtime linking enabled. Also drop use of `-brtl` for creating executables. Issue: #19163
* | AIX: Create import library for executables with exportsBrad King2019-07-164-5/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AIX, plugins meant to be loaded into executables via `dlopen` must be linked with access to a list of symbols exported from the executable in order to use them (when not using runtime linking). The AIX linker supports specifying this list as an "import file" passed on the command line either via the `-bI:...` option or (with a leading `#! .` line) as a normal input file like any other library file. The linker import file plays the same role on AIX as import libraries do on Windows. Teach CMake to enable its import library abstraction on AIX for executables with the `ENABLE_EXPORTS` target property set. Teach our internal `ExportImportList` script to optionally generate a leading `#! .` line at the top of the generated export/import list. Update our rule for linking an executable with exports to generate a public-facing "import library" implemented as an AIX linker import file. With this approach, our existing infrastructure for handling import libraries on Windows will now work for AIX linker import files too: * Plugins that link to their executable's symbols will be automatically linked using the import file on the command line. * The executable's import file will be (optionally) installed and exported for use in linking externally-built plugins. This will allow executables and their plugins to build even if we later turn off runtime linking. Issue: #19163
* | AIX: Explicitly compute executable exports for both XL and GNUBrad King2019-07-152-2/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AIX, symbols in executables must be exported in order to be visible to modules (plugins) they load via `dlopen`. Prior to policy `CMP0065`, CMake linked all executables with flags to export symbols, but the NEW behavior for that policy is to do so only for executables that have the `ENABLE_EXPORTS` target property set. In both cases, CMake has always used the AIX linker option `-bexpall` option to export symbols from executables. This has worked fairly well with the XL compiler, but with the GNU compiler it works only for C ABI symbols. The reason is that `-bexpall` does not export symbols starting in `_` but the GNU C++ ABI mangles all symbols with a leading `_`. Therefore we have only supported C ABI plugins with the GNU compiler on AIX. Some projects have tried to work around this by replacing `-bexpall` with `-bexpfull`, but the latter often exports symbols that we do not want exported. Avoid using `-bexpall` for executables by instead using by our own internal `ExportImportList` script to compute symbol export lists from the object files to be linked into an executable. Pass the explicitly computed export list to the AIX linker's `-bE:...` option. We already do this for shared object exports. Issue: #19163
* | AIX: Explicitly compute shared object exports for both XL and GNUBrad King2019-07-153-20/+60
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On AIX, symbols in shared objects must be exported in order to be visible to dependents (similar to Windows). The AIX linker provides a `-bE:...` option to specify a file listing symbols to be exported. Compilers offer some features to help: * When the XL compiler is invoked with its `-qmkshrobj`/`-G` options for creating shared objects (without/with runtime linking), it recognizes when no explicit `-bE:...` linker option is specified and runs a `CreateExportList` tool provided with the compiler to compute one from the object files. Since commit d468a2c2cb (XL: Avoid copying archives into shared libraries that link them, 2011-04-07, v2.8.5~153^2) CMake runs `CreateExportList` explicitly to ensure it only looks at the object files and not any library files. * When the GNU compiler is invoked with its `-shared` option for creating shared objects, its internal `collect2` tool recognizes when no explicit `-bE:...` linker option is specified and computes one itself from the object files. However, it sometimes includes extra symbols such as `.__init_aix_libgcc_cxa_atexit`. Introduce our own internal `ExportImportList` script to compute symbol export lists from object files. Use a basic implementation for now: it can be extended as needed later. Update our shared library creation rules to run the script explicitly for both the XL and GNU compilers. Issue: #19163
* | AIX: Drop redundant -brtl flagsBrad King2019-07-152-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We removed `-brtl` in commit bce7a2a3a5 (AIX: Do not use -brtl to create shared libraries, 2013-03-11, v2.8.11~103^2~1) but it was added again by commit f254276fc1 (AIX,HP-UX: Fix RPATH handling when CMP0065 is set to NEW, 2015-12-11, v3.4.2~4^2). Since the latter commit we initialize the `CMAKE_{SHARED,MODULE}_LINKER_FLAGS` to use the `-brtl` linker flag. This is unnecessary because we already use the `-G` linker flag which implies `-brtl`. The latter commit also moved `-brtl` to `CMAKE_EXE_LINKER_FLAGS` from flags that were always included in executable link lines with CMP0065 OLD behavior and are not part of the change intended by CMP0065. Leave this for now as we've always enabled runtime linking for executables (and implicitly done so via -G for shared libraries and modules). Issue: #13997 Issue: #19163
