RE: detecting the linaro toolchain via C/C++ preprocessor

by Vermeulen, Michiel

If your code is sensitive to the size of long long, can you use the predefine: __SIZEOF_LONG_LONG__ If that doesn't work, then you can use: gcc -dM -E - < /dev/null to tell you what predefines a gcc compiler has (I would probably look for predefines more specific to what your code is sensitive to than look for a particular compiler). I also wonder a little about your original problem statement since "%lld" should be a way to always print "long long" and if you have a matched set of compiler and library, then it should adjust both together. If you are using "%ld" instead, this works in situations where "long" is the same size as "long long" but may not work when these are different sizes. --mev, Mike Vermeulen

detecting the linaro toolchain via C/C++ preprocessor

by Isidor Zeuner

Hi there! On Linaro gcc 4.6, I am facing an issue due to "long long" integers not being 64 bit as they are on other platforms I'm targeting, which causes different issues, most importantly with printf format strings. I am now circumventing these by using the C/C++ preprocessor in order to choose the right format strings. In order to minimize the necessity for users to manually configure things, I'm wondering if there is a way to detect the Linaro gcc compiler through preprocessor macros. Is this possible? Thanks. Best regards, Isidor

Trouble executing ARM code on linaro toolchain

by Vishwa

Hi all, We are using Linaro 13.03 toolchain( gcc-linaro-arm-linux-gnueabihf-4.7-2013.03-20130313_linux We are trying to execute a simple test code to check whether ARM assembly code executes on board or not. Execution is on Arndale Board. Every time We include assembly function, We get segmentation fault. Kindly check if I We are missing any arm related flags in makefile. We have attached the ‘helloworld’ test code and makefile. Regards, Vishwa

Building 4.8 without multilib

by Diane Holt

Is that supposed to be possible? When I add --disable-multilib to the configure options, the build fails on the install, because it hasn't built any of src/gcc-linaro-4.8-2014.02/libgcc: /bin/sh ../../../../src/gcc-linaro-4.8-2014.02/libgcc/../mkinstalldirs /home/ubuntu/work483/build/sysroot/home/ubuntu/opt/cross-gcc-linaro/lib/gcc/arm-linux-gnueabi/4.8.3 /usr/bin/install -c -m 644 libgcc_eh.a /home/ubuntu/work483/build/sysroot/home/ubuntu/opt/cross-gcc-linaro/lib/gcc/arm-linux-gnueabi/4.8.3/ /usr/bin/install: cannot stat `libgcc_eh.a': No such file or directory make[3]: *** [install-shared] Error 1 make[3]: Leaving directory `/home/ubuntu/work483/build/gcc/arm-linux-gnueabi/libgcc' make[2]: *** [install-target-libgcc] Error 2 make[2]: Leaving directory `/home/ubuntu/work483/build/gcc' make[1]: *** [install] Error 2 make[1]: Leaving directory `/home/ubuntu/work483/build/gcc' make: *** [stamp/gcc-install] Error 2 I don't want or need multilib, so I'd rather build the toolchain without it, but before I try to make that happen, I wanted to make sure it's supposed to be able to get built correctly that way. Thanks, Diane
