RE: [ts-7000] gcc 4.x cross compiler

["Randall Philipson" <>]

Hi folks.  I’m a bit new to this so please forgive any stupid questions.

 

I’ve decided to try and build gcc-4.0.2 on my cygwin setup, first I discovered that I didn’t install all the components that I need.  I’m fixing that but I also got some messages that make me worry that I may not have my environment setup correctly as well.  They are;

 

BINUTILS_EXTRA_CONFIG not set, so not passing any extra options to binutils' configure script

GLIBC_EXTRA_CONFIG not set, so not passing any extra options to glibc's configure script

GLIBC_EXTRA_ENV not set, so not passing any extra environment variables to glibc's configure script

GLIBC_EXTRA_CC_ARGS not set, so not passing any extra options to gcc when building glibc

EXTRA_TARGET_CFLAGS not set, so not passing any extra cflags to gcc when building glibc

USE_SYSROOT not set, so not configuring with --with-sysroot

GCC_BUILD not set, assuming BUILD=output of config.guess

GCC_HOST not set, assuming HOST=BUILD

SHARED_MODE not set, so defaulting to --enable-shared

GLIBC_ADDON_OPTIONS not set, so guessing addons from GLIBCTHREADS_FILENAME and GLIBCCRYPT_FILENAME

 

Are the defaults generally OK or should I be paying more attention to the setting of these vars?  Any comments appreciated.

Hey all,

I just uploaded scripts to compile gcc-4.0.2 using the latest
crosstools-0.42. I've successfully built C, C++, Java, and gdb on both
Linux (FC4) and cygwin.

I matched glibc and Linux headers to what were already on the board
(glibc-2.3.2 & linux-2.4.26). I was also able to build this compiler
version against the default Linux 2.6.15 kernel and with different
versions of glibc.

Just download crosstools-0.42 tarball from kegel.com/crosstool, unpack
it, then untar the scripts I provided into the same directory. Then
just run "arm9tdmi.sh"

I built it on several host systems, but the latest FC5 wouldn't build
Java. If I removed "java" from arm9tdmi.sh it built everything else ok.

This version of gdbserver is also compatible with the latest
Insight-0.64, which I was able to build under Linux (but not cygwin -
yet). You can get that from sourceware.org/insight.


I've tested the C & C++ compilers, but not Java yet. Everything seems
to work well, but I am unable to debug pthreads. When I create a new
thread the debugger doesn't see it, and if I set a breakpoint in the
thread I get a SIGTRAP and the debugger stops working.

If anyone knows how to get this working, please let me know. Thanks

I'll try to post the prebuilt chains somewhere within the next few days.
