Summary0010545: Bootstrap script presumes that ${CC} can be invoked without ${CFLAGS}
DescriptionBuilding CMake 2.8.1 on 64-bit AIX, I get this error:

---------------------------------------------
Error when bootstrapping CMake:
Cannot find appropriate Makefile processor on this system.
Please specify one using environment variable MAKE.
---------------------------------------------
Log of errors: /tmp/cmake--2.8.1.build/Bootstrap.cmk/cmake_bootstrap.log
---------------------------------------------

I disabled the bit that deletes the temporary directory in which make-testing takes place, invoked the test myself, and saw this:

user@host:/tmp/cmake--2.8.1.build/Bootstrap.cmk/cmake_bootstrap_1048776_test_dir> make
"gcc" -o test test.c
Assembler:
/tmp//ccQCk1QK.s: line 9: 1252-191 Only .llong should be used for relocatable expressions.
/tmp//ccQCk1QK.s: line 57: 1252-191 Only .llong should be used for relocatable expressions.
make: *** [test] Error 1

The makefile looks like this:

----begin makefile----
test: test.c
        "tg-gcc" -o test test.c
----end makefile----

I manually edited it to this:

----begin modified makefile----
test: test.c
        "tg-gcc" $(CFLAGS) -o test test.c
----end modified makefile----

and got the following result:

user@host:/tmp/cmake--2.8.1.build/Bootstrap.cmk/cmake_bootstrap_1048776_test_dir> make
"gcc" -pedantic -pipe -fno-common -W -Wall -Wcast-align -Wformat=2 -Wpointer-arith -Wundef -Waggregate-return -Wcast-qual -Wmissing-declarations -Wnested-externs -Wstrict-prototypes -maix64 -mminimal-toc -O3 -o test test.c
test.c:3: warning: function declaration isn't a prototype

This is on a 64-bit AIX system that does not have the libraries needed to link 32-bit programs. GCC on this platform produces 32-bit binaries by default, unless you specify -maix64. Meaning, GCC without -maix64 doesn't work.
TagsNo tags attached.

 The attached patch, against 2.8.1, fixes this bug. (You may want to consider adding $(LDFLAGS) in there as well; some setups may require that.)

 I correct myself: This system actually can produce 32-bit libraries, but if you're not using -maix64, you have to set the OBJECT_MODE environment variable (or pass a special option in) or else the assembler complains:

> gcc -o foo foo.c
Assembler:
/tmp//ccbJJA40.s: line 1: 1252-192 Assembly mode is not specified.
        Set the OBJECT_MODE environment variable to 32 or 64 or
        use the -a32 or -a64 option.

> gcc -maix32 -o foo foo.c
Assembler:
/tmp//ccPOcuvf.s: line 1: 1252-192 Assembly mode is not specified.
        Set the OBJECT_MODE environment variable to 32 or 64 or
        use the -a32 or -a64 option.

> gcc -maix64 -o foo foo.c

>

$(CFLAGS) still needs to be passed to the compiler, of course.

 The bootstrap script copies CFLAGS into "cmake_c_flags" (and similarly for LDFLAGS). Most of the compiler invocations use them. Try this patch:

 Yep! The bootstrap process goes through with that change.
