gcc: Build error on Raspberry Pi

[pawan-saxena]

i am trying to build gcc on arm but as it hits the build for gmp 6.1.2 it fails right away. brew update && brew install gmp Error: Empty archive

I guess that since my gcc is 4.x so you don't support gmp version for arm. if not can you point me in rigth direction as to how to make gmp and hence gcc on raspberry pi3.

gist : brew gist-logs gcc and/or brew gist-logs gmp results in : Error : No logs

[alyssais]

Can you brew install -v gcc and post the output?

[pawan-saxena]

signature turns out to be okay :(

[sjackman]

The problem may be that the source tarball is xzipped rather than gzipped and you don't have xz available. Please report…

ls -l /home/pi/.cache/Homebrew/gmp-6.1.2.tar.xz
sha256sum /home/pi/.cache/Homebrew/gmp-6.1.2.tar.xz

[sjackman]

Try…

sudo apt-get install xz

[pawan-saxena]

[pawan-saxena]

I can't find xz but a lot of other similar packages, any suggestions which to use ?

[sjackman]

sudo apt-get install xz-utils

[sjackman]

Please avoid pasting screenshots, and instead copy-and-paste the text.

okay so i had same problem with curl it was reading it as /opt/curl/ (searching in user's root directory); i resolved that by creating a symlink

 ln -s /usr/bin/curl curl

here also i get this /opt/xz I guess that this issue may happen for other packages as well. Can you please suggest how to resolve it.

[pawan-saxena]

I made another symlink as :

pi@raspberrypi:~$ ln -s /usr/bin/xz /home/linuxbrew/.linuxbrew/opt/xz/bin/xz

and then tried to make build again It now stopped with same issue (this time python as /opt/python)

Have you installed these dependencies of Linuxbrew? http://linuxbrew.sh/#dependencies

[pawan-saxena]

i have installed these dependencies

sudo apt-get install build-essential curl file git python-setuptools

and then issues started to happen when gcc started building. I read all threads and adopted one approach where someone said that maybe i should delete linuxbrew altogether and start from fresh. I will seek your help if some issue happen again. But it think that would be only after 7-8 hours cause gcc build took 11 hours previously :)

https://gist.github.com/anonymous/cd7a11214115e7e1b8d6085f0d3a099d#file-config-log-L1061 Looks like compiling gmp requires a C++ compiler, but we haven't yet installed the brewed C++ compiler in gcc. Try…

sorry for late reply but in the process of building gcc i literally burnt it , i had set the overclock too much and swap to 3 Gib and now i can smell it burning...i will try to arrange a new one by tomorrow.Kindly don't close this ticket for now.

[sjackman]

Wow! 🔥 Since you're starting over anyway… this time around try not installing glibc.

brew install gcc --without-glibc

[pawan-saxena]

@sjackman first of all thank you for taking some time out to help me. I got it and ran the below command :

printf '#include <iostream>\nint main() { std::cout << "Hello, world"; return 0; }\n' >hello.cc
g++-4.9 -pipe -Os -g -O2 -o hello hello.cc -isystem/home/linuxbrew/.linuxbrew/include -Wl,--dynamic-linker=/home/linuxbrew/.linuxbrew/lib/ld.so -B/home/linuxbrew/.linuxbrew/opt/glibc/lib -L/home/linuxbrew/.linuxbrew/lib -Wl,-rpath=/home/linuxbrew/.linuxbrew/Cellar/gmp/6.1.2_1/lib -Wl,-rpath=/home/linuxbrew/.linuxbrew/lib

and i got :

The file gnu/stubs-soft.h is provided by the package libc6-dev-armel-cross on a hard-float ARM system (armhf): https://packages.debian.org/search?searchon=contents&keywords=gnu%2Fstubs-soft.h&mode=path&suite=stable&arch=armhf Try…

pi@raspberrypi:~ $ 

[sjackman]

gcc is configured with --disable-multilib. https://github.com/Linuxbrew/homebrew-core/blob/master/Formula/gcc.rb#L184 which should prevent it from needing gnu/stubs-soft.h. It looks like a bug in gcc to me that it still needs soft float. That doesn't help you though. As a super hack, you could try symlinking

/usr/arm-linux-gnueabi/include/gnu/stubs-soft.h

to

/home/linuxbrew/.linuxbrew/Cellar/glibc/2.23/include/gnu/stubs-soft.h

That likely get you past this particular error message. You're definitely in sketchy territory here though.

If you want to start over from scratch, I'd suggest removing everything and trying

brew install gcc --without-glibc

and avoid ever installing the brewed glibc. Alternatively, you need to configure and compile glibc with multilib support for soft floats.

[pawan-saxena]

i will try symlinking first cause gcc building took 22 hrs. so i guess i should give your first instruction a shot and see how things work out :)

[sjackman]

If you can read C code, you may want to read through gnu/stubs-soft.h and see whether there are any other header files that stubs-soft.h includes that you may need to symlink as well. Or perhaps symlink every file in the Debian gnu directory that doesn't already exist in the brewed glibc directory.

[pawan-saxena]

On it

[pawan-saxena]

Hello @sjackman i tried to find as many header files as i can and there are about 13 of them but still i failed to make them work. So now i am starting again on a new board and this time using :

brew install gcc --without-glibc
