[gentoo-embedded] GCC 4.3 fails on mpfr

[gentoo-embedded] GCC 4.3 fails on mpfr

[Dilip Malinur Ramesh]

Hi,
I am trying to build a cross compiler toolchain using 'crossdev 'and the
gcc source version is gcc-4.3.0 

I am getting following errors while configuring gcc-stage1, 
{{
checking for correct version of gmp.h... yes
checking for correct version of mpfr.h... no
configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+.
Try the --with-gmp and/or --with-mpfr options to specify their
locations.
Copies of these libraries' source code can be found at their respective
hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/.
See also http://gcc.gnu.org/install/prerequisites.html for additional
info.
If you obtained GMP and/or MPFR from a vendor distribution package, make
sure that you have installed both the libraries and the header files.
They may be located in separate packages.

!!! ERROR: cross-sh4-unknown-linux-gnu/gcc-4.3.0 failed.
Call stack:
}}

I understand the pre-requisite for gcc-4.3 is mpfr 4.1+ but I am not
sure how to pass '--with-mpfr' configure options to gcc.

Any help will be highly appreciated 

With kind regards,
Dilip

do you have mpfr and gmp already installed ?

qlist -I -v mpfr gmp

This is a 'chicken / egg' problem. In order to build a cross compiler 
for arch X you need mpfr compiled for arch X. In order to build mpfr for 
arch X you need a toolchain for arch X.

Try building the cross-compiler without mpfr first, then build libmpfr, 
and then rebuild the cross compiler.

I can't say whether or not that will work with crossdev, but that's the 
way things Should(TM) work.

you cant build gcc-4.3 without gmp and mpfr.  they're hard requirements.  but 
they're requirements that the host system has it, not that they are 
cross-compiled for the target.

Mike, 
this might pose a problem at Gentoo as I don't think mpfr can even be
cross compiled in the first place. I might be wrong but I seem to recall
fighting with it in the last week using ( arm-softfloat-linux-uclibc ||
arm*-softloat-linux-gnueabi).

i said they are host libraries, not target libraries.  gcc itself uses them in 
order to even execute in the first place starting with gcc-4.3.

what Christopher is probably referring to is gfortran support ... it requires 
mpfr/gmp to be cross-compiled.

but to address your question, they both do cross-compile fine.  i just did it 
two days ago for mingw32 target so that i could build up a gfortran 
cross-compiler.

looks like libtool hate, probably due to the stupid -rpath /usr/lib given to 
the libtool link line.  i bet if you deleted /usr/lib/libgmp.la it'd work ...

Mpfr librarires was not installed on my host system. I have now
installed it using 'emerge mpfr' [mpfr-2.3.1]. I have successfully built
cross compiler toolchain up to gcc stage 1 (using crossdev), currently
glibc is getting built and will update once it completes final toolchain
building.

Thanks and regards, 
Dilip

you cant build gcc-4.3 without gmp and mpfr.  they're hard requirements.
but 
they're requirements that the host system has it, not that they are 
cross-compiled for the target.

Hi,
I am able to successfully build cross compiler toolchain using gcc-4.3
after installing mpfr-2.3.1 libraries on host system.
Thank you for all your help and support.

i said they are host libraries, not target libraries.  gcc itself uses
them in 
order to even execute in the first place starting with gcc-4.3.

what Christopher is probably referring to is gfortran support ... it
requires 
mpfr/gmp to be cross-compiled.

but to address your question, they both do cross-compile fine.  i just
did it 
two days ago for mingw32 target so that i could build up a gfortran 
cross-compiler.

The joys of cross-compiles..

Had to move  libgmp.so out of the way so libtool did not find it
in /usr/lib64 but rather the $ROOT/usr/lib. After that mpfr cross-merged
without problem.

this is due to crossdev using --nodeps.  historically this was to keep random 
packages bleeding in, but i wonder if it's necessary anymore.

Re: [gentoo-embedded] GCC 4.3 fails on mpfr

[bscuser]

Hi there, sorry for writing again on this issue, but I have not been able to
solve the problem with the configure command on GCC 4.3 due to the
dependency on MPFR and GMP.

I have them both installed correctly and the headers are in their own build
directories, while the library files (*.a) are in /usr/local/lib.
This verified, I tried different options among which the following,

../configure --with-gmp=/Users/simone/myApplications/gmp-4.2.4/
--with-gmp-lib=/usr/local/lib/libgmp.a
--with-mpfr=/Users/simone/myApplications/mpfr-2.4.0/
--with-mpfr-lib=/usr/local/lib/libmpfr.a

but obtaining again the same error from the configure call:

configure: error: Building GCC requires GMP 4.1+ and MPFR 2.3.0+.
Try the --with-gmp and/or --with-mpfr options to specify their locations.
Copies of these libraries' source code can be found at their respective
hosting sites as well as at ftp://gcc.gnu.org/pub/gcc/infrastructure/.
See also http://gcc.gnu.org/install/prerequisites.html for additional info.
If you obtained GMP and/or MPFR from a vendor distribution package, make
sure that you have installed both the libraries and the header files.
They may be located in separate packages.


Why is this happening? What is it that I am not telling the configure to do
?

Thank you in advance
S.M.

just emerge mpfr and gmp

why ?  the ones you `emerge` should work fine.

Re: [gentoo-embedded] GCC 4.3 fails on mpfr

[bscuser]

Hi there, thanks for replying. How do I merge them? What does it exactly
mean? when I command "mergelib mpfr" I obtain "usage:  /usr/bin/mergelib 
to-library from-library [object-filename-prefix]" where I do not know what
the to-library would be in this case.

I am sorry about the questions, but I am a beginner in all this.
I hope you can help

Best
S.M.

this is Gentoo so the verb "emerge" means to run the program "emerge" and 
install the packages indicated
