Subject: Re: GUB and mpfr/mpc
I'm trying to update GCC on GUB and have a new virtual machine with
updated versions. I was having problems getting MPFR to build, but it
looks like I'ev fixed that with the new VM. However, it looks to me
like
GCC 4.8.2 has a new dependency on MPC that older versions did not:
there
appears no mention of MPC as a package in the current version of GUB.
My
most recent failure says this:
checking for the correct version of gmp.h... buggy but acceptable
checking for the correct version of mpfr.h... yes
checking for the correct version of mpc.h... no
configure: error: Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC
0.8.0+.
So it looks like we need to add a dependency on MPC. Problem is, I
don't
have a clue how to do this. I could try some stuff, but can anyone
here
help with how this dependency should be added to GUB?
TIA.
Did the error occur, while building cross/gcc?
If that is right, GMP/MPFR/MPC may be required for not GUB but host
OS.
The error is in the linux-86/log/cross/gcc-core.log file, so I assume
the answer is yes. However, my understanding is that the only package
that should need separately installing on plain Ubuntu/linux is git:
the rest should be downloaded and built by make bootstrap.

cross/gcc-core is built by host OS native gcc.
Would you try the following commands on your Ubuntu?
sudo apt-get update
sudo apt-get install libgmp-dev
sudo apt-get install libmpfr-dev
sudo apt-get install libmpc-dev
In my environment, I have succeeded in building of
linux-x86::cross/gcc-core.
However, I have still failed in building of linux-x86::glibc-core.

apt-get update ran fine. However, I get this for libgmp:
gub@gub-V2:~/gub$ sudo apt-get install libgmp-dev
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package libgmp-dev
