Bug#274942: static libs and object files fail to link when xgot needs to be used
Package: glibc,gcc
Severity: important
[I think this is the same issue as in bug #274738]
Trying to compile ghc6 on mipsel (all of this will apply equally to mips
AFAIK) I got a number of "relocation truncated to fit" errors when
linking the executable. After discussion with Thiemo Seufer I passed
-Wa,-xgot to gcc, which fixes all the errors refering to my symbols, but
I still got the errors below (partial output from passing the linker
-dll-verbose). They refer to these files
/usr/usr/lib/gcc-lib/mipsel-linux/3.3.4/../../../crt1.o
/usr/lib/gcc-lib/mipsel-linux/3.3.4/libgcc.a
/usr/lib/libc_nonshared.a
(although presumably any other static libraries and object files that
get pulled in may also need to be fixed too).
As I understand it the files would need to be compiled both as they are
now, and with the -Wa,-xgot flag to give e.g. crt1.xgot.o etc. gcc would
then need to look for these files first when given an xgot flag of some
sort.
The aforementioned errors:
