Building 2.27 on CentOS

Building 2.27 on CentOS

Hi everyone,

I’d like to build glibc under a CentOS to be packed in a RPM and a different root dir.
But currently I have problems with my build and hope someone can help me.

gcc   -nostdlib -nostartfiles -r -o /root/rpmbuild/BUILD/glibc-build/elf/librtld.os '-Wl,-(' /root/rpmbuild/BUILD/glibc-build/elf/dl-allobjs.os /root/rpmbuild/BUILD/glibc-build/elf/rtld-libc.a -lgcc '-Wl,-)' \

I regularly build upstream glibc with DTS 7 and have not seen anything 
like this.  How do you invoke configure and make?

Thanks,

Basically just run
configure —prefix=/somewhere/else
make

I tried with different options and CFLAGS etc. but currently I always end up with the same error.
Currently I try with CC=“gcc -fPIC” but make takes really a while on my machine..
When I use make -j6 then I get another error that some .os file does not exist, which I guess in this case is because the multiple jobs disturb each other.
I tried to attach config.log and make.log, but it seemed it didn’t came through on this mailinglist then.

To have a really clean environment for testing, I just tried it with a docker container based on centos/devtoolset-7-toolchain-centos7 and just added bison and make. So that’s my docker file:

```
FROM centos/devtoolset-7-toolchain-centos7

USER 0
RUN yum install -y --setopt=tsflags=nodocs bison devtoolset-7-make && yum clean all -y
USER 1001
```

From there I was just running `configure —prefix=/my/new/dir` and then make
Still facing the same error:

```

Any suggestions what am I missing or how can make this finally compile?

This looks like you are running under rpmbuild.  Please post the spec 
file, or upload it somewhere where we can see it.

You also have a funny character in the configure command line, but I 
assume that's just your email client.

All I can say so far that the glibc-2.27 tag generally builds fine with 
DTS 7.

Thanks,
Florian

My goal is to pack this in a RPM, but currently I just try to build it directly on the command line. Only after that works my next step would be to make it work with a spec file.
Maybe I have something wrong with my DTS 7 setup.. do you maybe have any sources you follow to setup you build environment that I could try to follow?

Thanks
Andreas

In this case, please show us the *exact* commands you use, not garbled 
by your mail client.  This includes the SCL activation step.

> Maybe I have something wrong with my DTS 7 setup.. do you maybe have any sources you follow to setup you build environment that I could try to follow?

I install devtoolset-7-gcc and devtoolset-7-gcc-c++, and the configure 
glibc with:

../git/configure --prefix=/usr CC=/opt/rh/devtoolset-7/root/usr/bin/gcc 
CXX=/opt/rh/devtoolset-7/root/usr/bin/g++
make -j4

Alternatively, running

scl enable devtoolset-7 -- bash

and entering

../git/configure --prefix=/usr
make -j4

in the subshell (!) works as well.

Thanks,
Florian

The commands I provided where the exact ones, just double dash is garbled by my mail client: — vs --
But I think I found now the reason. Since you claimed you always compile like that and never had issues, I tried with a vagrant virtual box on centos and it worked without any problem and also way faster.

The problem I had was because I was running the build in docker container on MacOS inside a mounted volume.
So I will try to first copy my base directory inside the docker container to build it there and then copy back the resulting files and if this still fails I have to check how I could run my builds on a VM directly instead of docker.

Thanks for your hints which took me to the conclusion that something with my environment must be wrong.
