Hi all,
Configuring binutils with --enable-targets=all fails when building gas at
obj-coff.o:
gcc -DHAVE_CONFIG_H -I. -I/gnu/binutils/binutils-2.16.92/gas -I. -D_GNU_SOURCE

make[4]: *** [obj-coff.o] Error 1
Both obj-coff.h and tc-i386.h seem to believe they 'own' TARGET_FORMAT.
/gnu/binutils/binutils-2.16.92/gas/config/obj-coff.h
59 #ifdef TC_I386
60 #include "coff/i386.h"
61
62 #ifdef TE_PE
63 #define TARGET_FORMAT "pe-i386"
64 #endif
65
66 #ifndef TARGET_FORMAT
67 #define TARGET_FORMAT "coff-i386"
68 #endif
69 #endif
/gnu/binutils/binutils-2.16.92/gas/config/tc-i386.h
66 #if ((defined (OBJ_MAYBE_COFF) && defined (OBJ_MAYBE_AOUT)) \
67 || defined (OBJ_ELF) || defined (OBJ_MAYBE_ELF))
68 extern const char *i386_target_format PARAMS ((void));
69 #define TARGET_FORMAT i386_target_format ()
70 #else
71 #ifdef OBJ_ELF
72 #define TARGET_FORMAT ELF_TARGET_FORMAT
73 #endif
74 #ifdef OBJ_AOUT
75 #define TARGET_FORMAT AOUT_TARGET_FORMAT
76 #endif
77 #endif
Ummm. The next thing I tried was to move that #ifdef TE_PE inside the
#ifndef TARGET_FORMAT, like so:
59 #ifdef TC_I386
60 #include "coff/i386.h"
61
62 #ifndef TARGET_FORMAT
63 #ifdef TE_PE
64 #define TARGET_FORMAT "pe-i386"
65 #else
66 #define TARGET_FORMAT "coff-i386"
67 #endif
68 #endif
69 #endif
and now all I get is
mkdir .libs

collect2: ld returned 1 exit status
make[4]: *** [as-new.exe] Error 1
make[4]: Leaving directory `/repository/davek/patch-gnu/binutils/obj-all/gas'
because of this:
1054 #ifdef USE_UNIQUE
1055 if (an_external_name != NULL)
1056 unique = an_external_name;
1057 #endif
where 'an_external_name' should exist in symbols.c:
62 #ifdef USE_UNIQUE
63 /* The name of an external symbol which is
64 used to make weak PE symbol names unique. */
65 const char * an_external_name;
66 #endif
but doesn't. It is defined in obj-coff.h under #ifdef TE_PE, but symbols.c
doesn't include obj-coff.h in this arrangement, because obj-coff.h is included
from obj-multi.h:
25 #ifdef OBJ_HEADER
26 #include OBJ_HEADER
27 #else
and OBJ_HEADER is only defined in the obj-*.c files and not in symbols.c.
Could anyone who knows better than me where the responsibility for setting
TARGET_FORMAT truly lies and what's the difference between a TC_xxxx and a
TE_xxxxx please comment on this clash? I don't yet get it myself. :-(
cheers,
DaveK
