i'm currently trying to do the documented (ARM cross-compile) build of a particular 2.6 source tree described here: http://www.embeddedarm.com/software/arm-linux-26-ts72xx.php the instructions in question: 1. Download and install (decompress) the cross-compiler on your Linux x86 PC 2. Download and install (decompress) the 2.6 Kernel source tree on your Linux x86 PC 3. Edit the Makefile at the Kernel root dir to point to the appropriate cross-compiler path 4. type “make ts72xx_defconfig” 5. type “make menuconfig” and edit the boot command line and other options of interest (optional) 6. type “make” which is fine except that the final make fails to compile thusly: HOSTCC scripts/mod/sumversion.o scripts/mod/sumversion.c: In function ‘get_src_version’: scripts/mod/sumversion.c:384: error: ‘PATH_MAX’ undeclared (first use in this function) scripts/mod/sumversion.c:384: error: (Each undeclared identifier is reported only once scripts/mod/sumversion.c:384: error: for each function it appears in.) scripts/mod/sumversion.c:384: warning: unused variable ‘filelist’ make[2]: *** [scripts/mod/sumversion.o] Error 1 make[1]: *** [scripts/mod] Error 2 make: *** [scripts] Error 2 this isn't actually a big deal -- turns out that, given the newer gcc-4.3 *host* compiler i'm using, the file scripts/mod/sumversion.c's reference to PATH_MAX now needs to include <limits.h>. so, i can do one of two things. slowly tweak the host-compilable source under scripts to be buildable with gcc-4.3, or just plain throw caution to the winds and replace the *entire* older (2.6.21) scripts/ directory with the current one (which means it will almost certainly compile with the native compiler). i'm just about to try the latter, but does anyone know off-hand any obvious reasons why a much newer scripts/ directory can't be dropped in place of an older one? rday -- ======================================================================== Robert P.
