Ah, ok. With 2.8.1:
C:/Program Files/Regina/regina.exe cc.rex dcc.exe CMakeCCompilerId.c
With 2.8.6:
C:/Program Files/Regina/regina.exe cc.rex;dcc.exe CMakeCCompilerId.c
Note the semicolon; where'd it come from? It's not in the toolchain file:
I did not notice previously that the reported ; is coming from a message()
command in a string and not a real command line that is invoked. The
2.8.1 output line misrepresents the actual command that is running.
What you mean by:
> SET(CMAKE_C_COMPILER "regina.exe" "cc.rex dcc.exe")
> SET(CMAKE_CXX_COMPILER "regina.exe" "cc.rex dcxx.exe")
is that you want the compiler to be invoked as
"regina.exe" "cc.rex dcc.exe" "CMakeCCompilerId.c"
where the second piece puts both files in a *single* argument, right?
Much of the discussion in this thread made it appear that you wanted
"regina.exe" "cc.rex" "dcc.exe" "CMakeCCompilerId.c"
but that is what the above-mentioned execute_process command ends up
running in 2.8.6 and causing the hang.
Correct?
