<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>We (MARVELL Switzerland) have created some CMake support files
in order to use RVDS 4.1 ARM C/C++ and ASM compilers.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>What works:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>* The ASM compilation works just fine, except for <FLAGS>,
we don’t know how to use that so we just hardcoded the flags in the CMakeASM-RVDSInformation.cmake
file.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>* The C and C++ compilation and static libraries generation
work with one caveat: we hardcoded “armar” in CMAKE_C_CREATE_STATIC_LIBRARY
and CMAKE_CXX_CREATE_STATIC_LIBRARY because setting CMAKE_AR doesn’t work
for us.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>What doesn’t work:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>* We cannot use armcc for linking because we need to use a
scatter file for memory and this requires using armlink. Unfortunately, setting
CMAKE_CXX_LINK_EXECUTABLE doesn’t work for us because:<o:p></o:p></p>
<p class=MsoNormal>1) we did not find how to set the arguments of armlink
correctly<o:p></o:p></p>
<p class=MsoNormal>2) armlink requires an object file as first input, giving
only static libraries doesn’t work<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>So, as a workaround, we install our static libraries in a
dedicated “archive” folder and we use a build script for the final
linking step thanks to a custom target:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> file(GLOB archives ${CMAKE_BINARY_DIR}/archive/*.a)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> add_custom_target(fw ${CMAKE_SOURCE_DIR}/../cmake/link.sh
${CMAKE_BINARY_DIR} ${CMAKE_SOURCE_DIR}<o:p></o:p></p>
<p class=MsoNormal> WORKING_DIRECTORY
${CMAKE_BINARY_DIR}/archive)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I also attach our build script for reference.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This works for us but obviously is far from optimal. So we
are contributing this in the hope that it is useful to you and also that it can
be improved. If some CMake developer can help us improve this, we would be
happy to test and help of course.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Thanks in advance and regards,<o:p></o:p></p>
<p class=MsoNormal>Abdel<o:p></o:p></p>
