xgcc: error: unrecognized command line option '-V'

[denizzzka]

Hi!

I am tried to use step-by-step instructions from wiki and this bash script to build toolchain on Debian GNU/Linux 8 and in both cases got this error after execute "make -j4 all-target-libgcc":

Previous line "make -j4 all-gcc" is succeeds.

Can you help with this problem?

I'm not quite sure, but I think it's because it can't find some of the libraries needed by the compiler. See the "Prerequisites" section here: http://wiki.dlang.org/GDC/Development/DevelopmentEnvironment. Be sure to use your package manager to install libmpc-dev, libmpfr-dev, and libgmp3-dev and then run the build again.

[denizzzka]

Checked, everything from wiki list and libmpc-dev, libmpfr-dev, and libgmp3-dev is installed

http://superuser.com/questions/846768/gcc-unrecognized-command-line-options-v-and-qversion-with-autoconf

gcc used to have a -V option for version reports. It now uses -v, and provides the configuration options used when the compiler was built.

BTW, the -qversion option was merged into the -v...

It is need to downgrade build scripts or that?

I also found http://forums.debian.net/viewtopic.php?f=8&t=98199

But, I really don't know. I suggest posting a question at http://forum.dlang.org/group/D.gnu. There are a few folks there that have a much deeper knowledge of GCC than I.

It did not help too

Ok.

What autoconf version do you use?
-V presented in gcc-4.3, but removed later and did not exists in 4.9

[JinShil]

autoconf --version gives me autoconf (GNU Autoconf) 2.69

gcc --version gives me gcc (GCC) 4.9.2 20150304 (prerelease)

I'm using Arch Linux 64-bit

It has come to my attention that the prebuilt binaries at http://gdcproject.org/downloads are capable of creating ARM Cortex-M binaries. I just tested it myself.

I used the arm-linux-gnueabihf build, and the command I used for my STM32F4 (ARM Cortex-M4F) was:
arm-gdcproject-linux-gnueabi-gdc -fno-emit-moduleinfo -frelease -mthumb -mcpu=cortex-m4 -fdata-sections -ffunction-sections -c start.d

The key is to simply add the platform flags: -mthumb -mcpu=cortex-m4

If you're still having trouble with this build, you may want to just go that route and just download the pre-built binary.

Thanks!
