Hello,
on both Solaris 11 and OpenBSD 5.7 I do have an issue with source
builder which fails on newlib compilation. This shows as:
checking for sparc-rtems4.11-ar... sparc-rtems4.11-ar
checking for sparc-rtems4.11-ranlib... sparc-rtems4.11-ranlib
checking for sparc-rtems4.11-readelf... sparc-rtems4.11-readelf
checking whether to enable maintainer-specific portions of Makefiles... no
checking for a sed that does not truncate output...
/tmp/rtems-sparc-toolchain/bin//sed
checking how to print strings... print -r
checking for gawk... (cached) gawk
configure: error: big5 is not supported - see
../../../gcc-4.9.2/newlib/libc/iconv/encoding.aliases file for the list
of available encodings
gmake[1]: *** [configure-target-newlib] Error 1
gmake[1]: Leaving directory
`/export/home/karel/vcs/rtems-source-builder/rtems/build/sparc-rtems4.11-gcc-4.9.2-newlib-2.2.0.20150423-i386-pc-solaris2-1/build'
gmake: *** [all] Error 2
the problem is in newlib's configure file which strictly requires GNU
sed/grep combo. The problem is the configure file itself invokes just
"sed" and "grep". So there are two solutions to this issue:
Either:
- disable iconv as I did for OpenBSD in provided patch in source builder
platform file
or
- put GNU sed and grep (perhaps grep is enough, but I would need to
retest) into PATH in front of original system's grep/sed. This makes
newlib configure happy.
The general question is what's better and how to solve this issue? Just
a note in builder doc for both platforms? Or custom patch to newlib to
check for ggrep/gsed and when available to use them? Or just disabling
iconv completely in platform .py file of the source builder itself? Or
hacking source builder to support building GNU sed/grep on problematic
platform, installing in RTEMS bin and use that and this way make newlib
happy?
Any idea/preference welcome here.
Thanks!
Karel
