7e24997 GenerateExportHeader: Generate only C identifiers as defines
2013-05-24 09:20:20 -04:00
Stephen Kelly 7e24997fed GenerateExportHeader: Generate only C identifiers as defines
The variables in this module are used to configure a header file
with defines whose name depends on the name of the target.

As valid names of targets may be invalid for use as defines, convert
the names of the defines used to C identifiers first. This is already
done in C++ code for the DEFINE_SYMBOL property.

This is not as simple as ensuring that the BASE_NAME is a C identifier,
because most of the define names are configurable, and because use of
a BASE_NAME which is not a C identifier, such as 4square can become a
C identifier by specifying a prefix in the generate_export_header
macro.

Stephen Kelly 7ffef5024a GenerateExportHeader: Allow use of of this macro with MODULEs.
The significant issue with MODULEs is that on Windows, the exported
symbols must be dllexported and they are not imported.

In other export macro implementations this is done by defining an
export macro outside of any ifdef which depends on definitions set
on the command line. However, with cmake we already expect the
DEFINE_SYMBOL to be defined, so the regular EXPORT macro can be
used by such plugins.

Marcus D. Hanwell 1e0891e28a Removed GenerateExportHeader warnings about old compilers
These warnings tend to flood the dashboard submissions, and it is doing
what it should (degrade gracefully with older compilers).

Stephen Kelly 0ebf332199 Fix GenerateExportHeader documentation #13936
There is no CMAKE_CURRENT_BUILD_DIR. CMAKE_CURRENT_BINARY_DIR is
the correct variable here.

Rolf Eike Beer c28e276948 GenerateExportHeader: improve compiler identification
Use CMAKE_<LANG>_COMPILER_VERSION instead of calling the compiler. This macro
predates those useful variables. This also fixes the issue that g++ version
detection was not working if C language was not enabled.

Rolf Eike Beer 4412fc0890 GenerateExportHeader: remove unneeded code
These expressions check for command line arguments unsupported by the compiler.
We don't pass any custom flags here anyway so this isn't needed.

Stephen Kelly 40efa4db74 Fix documented function signature to match reality.
The function description is already correct.

Alex Neundorf 54e1f6f5a5 GenerateExportHeader: use double quotes around _gcc_version
The GenerateExportHeaders test was failing on one machine, the version
could not be determined there, so the _gcc_version was empty,
so the first argument to if() was empty, so it complained:
http://open.cdash.org/testDetails.php?test=135623436&build=2016288
Use double quotes to turn the non-existant first argument into an empty
string.

Marcus D. Hanwell 41e2b1d824 Make add_compiler_export_flags a function again.
Making this a macro had unintended issues on (among others) Windows
compilers. Moving it back to being a function using PARENT_SCOPE still
satisfies the use case where we simply want to obtain the extra flags.
2011-09-20 00:16:16 -04:00
Marcus D. Hanwell 6a10deb670 Made ADD_COMPILER_EXPORT_FLAGS into a macro.
It adds to the CMAKE_CXX_FLAGS (as before), or populates the supplied
optional argument with the CXX_FLAGS for symbol import/export.

David Faure 6a6393c905 Don't use a variable name that might be used in other files.
myDir is also used in the Grantlee config file, so if Grantlee
was found, this call failed.

Stephen Kelly aed84517c9 Test for deprecated attribute before declspec.
The attribute seems more common, and some compilers seem to silently
ignore the declspec.

Stephen Kelly df4615e338 Add the COMPILER_HAS_DEPRECATED only if it has a declspec variant
_check_cxx_compiler_attribute does it in the alternative.

Stephen Kelly 399f415b15 Only set the deprecated attribute if hidden visibilty is enabled.
This is what is tested in the unit test. If it makes sense, another
option can be added later.

Stephen Kelly 7924c1d6a8 Another attempt at fixing Borland.
Apparently it still needs to be exported, but only declspec(deprecated)
does not work.

Stephen Kelly cff9493598 Only set the COMPILER_HAS_HIDDEN_VISIBILITY if GCC >= 4.2
Hearsay has it that before that version it didn't work properly.

Hopefully this will fix more dashboard builds.
