GNU Arm Embedded Toolchain

Suggested changes for ./build-toolchain.sh --debug

Asked by Joe Gorse

Building with ./build-toolchain.sh --debug fails on Mac OS X 10.7 for lack of quotes for multivariable arguments to variables in the following way--

Excepted Build Log:

Suggested change (1) to build-toolchain.sh is from line 61.old to 61, wherein we insert single quotes to explicitly denote the string of build options:
 60 --debug)
 61.old DEBUG_BUILD_OPTIONS=" -O0 -g "
 61 DEBUG_BUILD_OPTIONS="' -O0 -g '"
 62 ;;

Suggested change (2) to build-toolchain.sh is from line 296.o to 296, wherein we again insert single quotes to explicitly denote the string of build options:
295 make -j$JOBS ${GCC_FINAL_CFLAGS} \
296.o INHIBIT_LIBC_CFLAGS="-DUSE_TM_CLONE_REGISTRY=0"
296 INHIBIT_LIBC_CFLAGS="'-DUSE_TM_CLONE_REGISTRY=0'"
297

This appeared to build properly with the '/build-toolchain.sh --debug' command.

Cheers,
Joe

I apologize, those proposed fixes do not actually work as integrated into the entire script.

Here is the proper working patch (so far):

Apparently the escape mechanisms for echo and bash are not the same. I am testing yet another fix and will post the diff if it actually succeeds on the compile. Cheers.

I suppose if you can't get Bash to escape correctly when you send the command to make, it's best not to fight it too hard and just get make to expand the variables (putting variable names inside parenths()'s ). So much for Bash.

Thanks Joe. This issue is confirmed and should be fixed in next release.
