Hei hei, at the moment we are using ptxdist 2013.07.1 with OSELAS toolchain 2012.12.1 for arm-v5te. We usually have set -Wcast-align in the extra toolchain options (TARGET_EXTRA_CFLAGS and the two for C++) to spot alignment problems in our code. Most software packages throw alignment warnings. Ignoring what this actually means, this is no problem as long as the package does not set -Werror. gdb sets -Werror. We tried most currently available versions of gdb and the build fails, e.g. like this:
/home/adahl/Work/bsp/XXX/platform-XXX/build-target/gdbserver-7.5/gdb/gdbserver/../common/agent.c: In function 'agent_look_up_symbols': /home/adahl/Work/bsp/XXX/platform-XXX/build-target/gdbserver-7.5/gdb/gdbserver/../common/agent.c:95:2: error: cast increases required alignment of target type [-Werror=cast-align] cc1: all warnings being treated as errors make[1]: *** [agent.o] Error 1 I guess one could dig into gdb sources, find and hopefully fix the problem, make a patch, send it to upstream and to ptxdist, wait, do all the usual things. One could also drop the additional flag globally. My question: is it possible to override the TARGET_EXTRA_CFLAGS per package? Maybe in rules/gdbserver.make? Or would this be a bad idea? I'd like a quick solution where I don't have to dig into gdb source code and can keep the global target warnings. O:-) Greets Alex -- »With the first link, the chain is forged.
