hello,
My build step is not thread-safe (the instruction in the COMMAND part).
Every build step depends on one source file:
/add_custom_command(//
// DEPENDS on_source.file//
// OUTPUT//
// object_file_for_source_file//
// COMMAND not-thread-safe-compiler --build on_source.file//
// COMMENT//
// "Building Source object"//
//)/
add_custom_target DEPENDS on OUTPUT from all custom command's, but in
order to prevent parallel execution when cmake is called:
/cmake --build . --target all -j30/
I need to build each step in any order, but still not as a dependency as
this would trigger unnecessary recompilation. Using MAIN_DEPENDENCY
defines hierarchical dependency, but this won't help in this situation.
I cannot figure out how to prevent parallel execution of COMMAND in
CMake. The only option I see is a single command
/add_custom_target(tgt//
// DEPENDS on_all_source.files//
// COMMAND not-thread-safe-compiler --build on_source1.file/
/ COMMAND not-thread-safe-compiler --build on_source2.file/
/ COMMAND not-thread-safe-compiler --build on_source3.file/
/ . . .//
/
/ COMMENT//
// "Building target"//
//)/
this would rebuild every source, though.
How do I set this up?
thank you
