<div style="text-align: left;">Hi there,<br><br><br><br>The attached file (multi-toolchain.patch.bz2) is a patch I made for supporting multiple tool-chain in single source tree.<br><br>The idea is add an extra property "TARGET_ARCH" to target <br>and make the variable expansion routine lookup toolchain according to TARGET_ARCH.<br><br>For example, if TARGET_ARCH is set as CPUX (ie: SET_TARGET_PROPERTIES(my_target PROPERTIES TARGET_ARCH CPUX) ), <br>the modified expansion routine will check CMAKE_C_COMPILER_CPUX first when cmake attempts to generate statements which reference to C compiler.<br><br>For heterogeneous computing environment such as grid / clustering or Cell (the multiple core processor used in PS3), such support would be useful.<br><br><br>Besides the patch, two module files for supporting Cell SDK 3 are also attached.<br>Those modules would find toolchain binaries and adjust compiling rules for you.<br><br><br><br><br>Here is an example of CMakeList.txt for a HelloWorld in Cell:<br><br>First of all, the layout of source tree:<br>{{{<br>ProjectRoot $ ls -RF .<br>CMakeLists.txt <br>spe/<br>ppe/ <br>toolchain.cmake<br><br>./ppe:<br>CMakeLists.txt <br>main_ppe.c<br><br>./spe:<br>CMakeLists.txt <br>main_spe.c<br><br>}}}<br><br>====<br>The CMakeList-s.<br><br>$ProjectRoot/CMakeList.txt<br>{{{<br><br>project (HELLOCELL)<br><br>add_subdirectory(spe)<br>add_subdirectory(ppe)<br><br>}}}<br><br>----<br><br>$ProjectRoot/ppe/CMakeList.txt<br>{{{<br>add_executable(ppe_helo main_ppe.c)<br>target_link_libraries(ppe_helo spe2)<br>target_link_libraries(ppe_helo pthread)<br>set_target_properties (ppe_helo PROPERTIES TARGET_ARCH PPU)<br><br>target_link_libraries(ppe_helo "${HELLOCELL_BINARY_DIR}/spe/Hello_CBE_SPE.a")<br><br>}}}<br><br>----<br><br>$ProjectRoot/spe/CMakeList.txt<br>
