Sage 4.1.2 : R compilation failure

[bourbabis]

Hello Sage team.

So the R package compilation has failed. My current gcc version is
4.3.2 and Sage version 4.1.2
Quote from log :

"/opt/Sage-4.1.2/spkg/build/r-2.9.2/src/bin/exec/R: /opt/Sage-4.1.2/
local/lib/gcc-lib/i686-pc-linux-gnu/4.0.3/libgcc_s.so.1: version
`GCC_4.2.0' not found (required by /usr/lib/libstdc++.so.6)"

Must I use this specific version of gcc ? Here is the whole logfile :

Thanks again.

Hi, I can confirm this with Ubuntu 9.10 (the beta of the next one)
using gcc 4.4.1.

The line says:

make[6]: Leaving directory `/home/harri/sage/sage-4.1.2/spkg/build/
r-2.9.2/src/src/library/base'
/home/harri/sage/current/spkg/build/r-2.9.2/src/bin/exec/R: /home/

libgcc_s.so.1: version `GCC_4.2.0' not found (required by /usr/lib/
libstdc++.so.6)

Copying the system's libgcc_s.so.1 (e.g., /lib64/libgcc_s.so.1) to

SAGE_LOCAL/lib/gcc-lib/x86_64-unknown-linux-gnu/4.0.3/libgcc_s.so

and trying "make" again gets the build to finish, at least, on 64-bit
Fedora 10.

That could probably be solved by adding a linker flag during the build process
(-R and/or -L) or by setting LDFLAGS at runtime. I'd much prefer the former
myself. It should not be necessary to copy the file. (This is from someone who
does not run linux though!)
