If you are just wanting your C++ test library to be able to test your C source then I would still let them compile as C and just extern “C” { #include <your header> }. When it gets linked all together it should be fine. This is how I usually do testing of my C code with cpputest which is also a C++ library.</div> <br> <div id="bloop_sign_1516212463430073856" class="bloop_sign"><div style="font-family:helvetica,arial;font-size:13px">-- <br>Matt Keeler<br><br></div></div> <br><p class="airmail_on">On January 17, 2018 at 13:05:36, Jimi Damon (<a href="mailto:jdamon@accesio.com">jdamon@accesio.com</a>) wrote:</p> <blockquote type="cite" class="clean_bq"><span><div><div></div><div>

<div dir="ltr">Hi,
<div><br></div>
<div>I want to use Gtest for some unit tests on a number of the C
functions that comprise my C executable. However, Gtest ( And
gMock ) are C++ testing frameworks. </div>
<div><br></div>
<div>What I would like to have is a project for my exe and then a
separate project for my C++ library and be able to change the
source properties to use the language CXX just before
compiling.</div>
<div><br></div>
<div>The problem I'm having is that CMake uses the CXX compiler for
the C files.</div>
<div><br></div>
<div><br></div>
<div>Here's what I would like to have</div>
<div><br></div>
<div>project(cexe)</div>
<div>set(SOURCES foo.c bar.c )</div>
<div>
<div>add_executable( cexe ${SOURCES} )</div>
</div>
<div><br></div>
<div>project(cpplib)</div>
<div>
<div>set_source_files_properties(${SOURCES} PROPERTIES LANGUAGE CXX
)</div>
</div>
<div>
<div>add_library( cpplib SHARED ${SOURCES} )</div>
</div>
<div><br></div>
<div><br></div>
<div><br></div>
<div>Is there a way to do this ? </div>
<div><br></div>
<div>Can target_compile_options set the compile type for a given
target ? </div>
<div><br></div>
<div><br></div>
<div>In the past I've had to copy the .C files to some renamed .CPP
equivalent and then compile off of that. </div>
<div><br></div>
<div>I'm hoping that enough new functionality has been added to
Cmake to allow separation between compiles.</div>
<div><br></div>
<div><br></div>
<div>Thanks,</div>
