Hi,
I'm trying to do the following in my CMake file:
1. Generate a "xyz.txt" file
2. Compile a "generate.c" file to give out a "generate" binary in my bin
directory.
3. Execute the "generate" binary (The binary just reads contents of
"xyz.txt" and creates a copy of "xyz.txt"using read() and write() functions
in C)
The problem:
When I do a fresh build, 1 and 2 succeed. 3 fails with the following error
*"bin/generate: Command not found"*
However, if I *re-run the build immediately* after, since the "generate"
binary is already created, all 3 successfully execute. Here's a snippet of
what I have written.
------------
------------
/*---- Code to generate xyz.txt -- Successfully generated each time------*/
----------
---------
ADD_EXECUTABLE(generate ${CMAKE_CURRENT_SOURCE_DIR}/server/generate.c)
set(GEN ${CMAKE_BINARY_DIR}/bin/generate)
ADD_CUSTOM_COMMAND(
TARGET generate POST_BUILD
COMMAND ${GEN}
DEPENDS ${CMAKE_BINARY_DIR}/server/xyz.txt}
)
In my ADD_CUSTOM_COMMAND, I have specified POST_BUILD, which I understood to
be that the command will be executed only after creation of the "generate"
binary.
Any help is greatly appreciated. Thank you in advance for your time.
Regards,
Swaroop
