Dear all,
I am trying to build shared libraries on Windows exporting all
symbols. This is as an alternative of instrumenting the code with
dllimport/dllexport declarations. For this I do build first a static
library from which I get all the defined symbols to write a .DEF
file which is then used to build the shared library. The CMake code
(using version 2.8.3) looks like this:
add_library( ${library}-static STATIC ${sources} )
add_custom_command( OUTPUT {library}.def COMMAND <using ${library}-
static> DEPENDS ${library}-static )
add_library(${library} SHARED ${library}.def)
target_link_libraries(${library} ${library}-static ${other-libs} )
set_target_properties(${library} PROPERTIES LINK_INTERFACE_LIBRARIES
${other-libs})
This works just fine when using the nmake generator. The library
is created and has all the symbols are exported as desired. But,
when using Visual C++ 2008 express edition I get the following error
message:
1>.\mylib.dir\Debug\mylib.dll.intermediate.manifest : general error
c1010070: Failed to load and parse the manifest. The system cannot
find the file specified.
The problem is that the shared library has been defined without any
'real' source file (only the .def file is declared) and somehow the
generated code does not produce the required manifest file. Does
anybody see a problem with these kind of constructs? Should it just
work from within the IDE?
Experimentally I have found a workaround, which consists in adding
a dummy source file in the shared library definition.
...
file( WRITE ${library}.cpp "// empty file!!!\n" )
add_library( ${library} SHARED ${library}.cpp ${library}.def)
...
I have also noticed that the dependency of the shared library to
the .def file is also missing. This is, newer versions of the .def
file does not trigger a re-build of the shared library.
