[Scons-users] FW: how to execute Clang static analyzer perl script instead of gcc.exe on Mingw/MSYS

[Dennis Cote]

Hi,

 

I'm using SCONS to build some C code. So far it seems to be working well
executing gcc.exe from the /mingw/bin directory in an MSYS shell.   

 

Now I need to have it send the same commands to a perl script,
ccc-analyzer, used by the Clang static analyzer to interpose itself into
a build. I tried adding  CC='ccc-analyzer' to the construction
environment and it generates what seems to be the correct command lines,
with the command beginning with ccc-analyzer instead of gcc, but the
commands fail with the following error:

 

'ccc-analyzer' is not recognized as an internal or external command,

operable program or batch file.

 

For comparison here are the first command lines generated with and
without CC='ccc-analyzer'.

 

ccc-analyzer -o build\DXL\GoAheadWeb\asp.o -c -Wall -include builtin.h
-I. -DNU_MMU_MODE=0 -DNU_MODULE_SUPPORT=1 -DNU_SUPERV_USER_MODE=1
-DNU_DEBUG=1 -DXL_DEBUG_ENABLE=1 -DDXLIO_METHOD=DXLIO_TELNET -DENDIAN=0
-DNUDEBUG_MEMORY -D_SH4 -DUEMF -DWEBS -DNUCLEUS_NET
-Ibuild\DXL\GoAheadWeb -Ibuild\ATI -Ibuild\DXL\Intercom\hdr
-Ibuild\ATI\plus build\DXL\GoAheadWeb\asp.c

 

gcc -o build\DXL\GoAheadWeb\asp.o -c -Wall -include builtin.h -I.
-DNU_MMU_MODE=0 -DNU_MODULE_SUPPORT=1 -DNU_SUPERV_USER_MODE=1
-DNU_DEBUG=1 -DXL_DEBUG_ENABLE=1 -DDXLIO_METHOD=DXLIO_TELNET -DENDIAN=0
-DNUDEBUG_MEMORY -D_SH4 -DUEMF -DWEBS -DNUCLEUS_NET
-Ibuild\DXL\GoAheadWeb -Ibuild\ATI -Ibuild\DXL\Intercom\hdr
-Ibuild\ATI\plus build\DXL\GoAheadWeb\asp.c

 

 

The file ccc-analyzer is a perl script that passes the gcc arguments to
the clang compiler for static analysis and then on to gcc to build the
object files. It is found on the path as shown below. These command were
executed from the same shell used to run scons. 

 

$ which ccc-analyzer

/mingw/bin/ccc-analyzer

 

$ which gcc

/mingw/bin/gcc.exe

 

Both command work from the shell command line as shown below.

 

$ gcc --version

gcc.exe (GCC) 4.7.2

The scons environment path imports the shell path as shown below.

 

env = Environment(ENV = {'PATH' : os.environ['PATH']},

                tools = ['mingw'], 

                CC='ccc-analyzer', 

                CFLAGS=flags, CPPDEFINES=defs)

 

One thing that is different between gcc and ccc-analyzer is that the gcc
executable has a ".exe" extension which the perl script lacks. This can
be seen in the which command output above. I suspect scons may be
passing the commands to an shell that is expecting all commands to be
implemented by *.exe (or *.com, or *.bat) files, and it can't find a
ccc-analyzer.exe to run. 

 

Does anyone have any idea why scons can't run the ccc-analyzer script?
More importantly, does anyone have an idea how to fix it so it can run
this script? 

 

Thanks.
