#68851 — How to debug this make error?

Hi,

I have a C project having cmake. The generated Makefile can generate an error
when run make, see below please.

The program runs on Ubuntu Linux 14.04, 32-bit. It is rather no clue for me to find the bug. Could you help me?

Excuse me, the above message should be:
..............................

.........
It is really puzzling why it needs permission.
The computer is a Ubuntu Linux, 32-bit. The project is a cross-compiling to ARM.

	What I find puzzling is why is the makefile trying to execute 
what seems to be an assembly language source file. Since it is generated 
by the makefile, it would seem that the expectation is to create an 
executable from this file, and then execute it.

Without more information it's impossible to know what's happening
there. It might also be possible that creating the '.s' file fails
because of missing permissions to write to the target directory.
I've read somewhere that starting make with

   make VERBOSE=1

may increase the amout of information output considerably - perhaps
that would give a clearer picture. But the OP should really consider
asking that kind of questions in a group or forum that actually is
about cmake, comp.lang.c is definitely not the place to look for
information about tools that might be used in compiling code.

Very odd.
It looks like the makefile is generating an assembly file on the fly, then calling the
shell interpreter on it. Naturally there shell interpreter refuses to execute the
script.
However makefiles are very difficult to correct. It's unlikely to be coding the invocation
of sh in any obvious way, and it's not clear what it really wants to achieve.

That Makefile obviously was created by cmake, so it's the
input files for cmake that should be looked at, not the
resulting Makefile. And one not so uncommon mistake new
users of cmake tend to make is trying to run cmake and
build in the source directory, even though this strongly
discouraged. This can have really weird results...

Thanks. I have subscribed cmake maillist, but never receive a activating email.

Excuse me I have to ask question here.

I have turn on VERBOSE in the following make.
Can you see any suspicious thing? 

Thanks,

One thing suspicious is that the Makefile wasn't provided in the
original post.  Another is that make errors are off-topic in
comp.lang.c .

...

Ok, here's the command that failed (above).  It's obvious that the command
is missing after the && and it's trying to execute a source file, hence
you get an accurate but very misleading complaint about file permissions.
Some variable has expanded to a 0-length string when it shouldn't.

The command as written in the Makefile is probably something like this:

	cd $(FUNKY_SUB_DIRECTORY); $(FUNKY_CODE_GENERATOR) $(FUNKY_FILE_ONE) $(FUNKY_FILE_TWO)

where FUNKY_CODE_GENERATOR is an undefined variable that shouldn't
be undefined.  Since the line above it says Generating ... *.s,
it's some command that generates an assembler input file, or possibly
a copy command, copy-if-newer command, copy-if-different or a
preprocessor for assembly-language files.  It may or may not need
option flags.

Find the undefined variable and define it correctly.  It appears
directly after && in a command line, although it might come from
system-default patterns and be harder to find.

The variable names I used above are examples only, and I'm pretty
sure they don't match the ones actually used.

The cmake --warn-unitialized flag is supposed to warn you when an
uninitialized variable is used.  This may, however, lots of trigger
non-useful warnings on a whole bunch of optional things that can
go on a command line, such as those for compiler flags, debug flags,
extra libraries, etc.

This does not appear to be a C question.  You might try asking in
comp.unix.programmer.

If you do, they're probably going to need more information than you've
provided, at least the input to cmake.

It is rather no clue for me to find the bug.

Some Makefiles are meant to be hard-to-debug,
eg. every command in them begins with an @atsymbol.

Don't hesitate to fix them:
sed 's/^<tab>@/<tab>/' Makefile >Makefile.test

The cmake configuration file has such settings, especially I am interested in
assembler setting. After check cmake website, I don't find an environment

how to correct it.
