Hello. I maintain ScummVM port for Symbian Series 60v3. ScummVM is a complete rewrite of hundreds old games' executables and is not an emulator. It's free and opensource.
Last year, when I prepared a version 2.2.0 in the release, it was faced with the fact that when the Ultima engine is turned on in the executable file (supports Ultima 1, 4, 6, 8), it does not start. Ultima 4 & 6 support disabling allowed SCUMMVM. In the spring of this year, after some changes in the source code Ultima, the elf2e32 utility has begun to complete the work with the error "Line 427". To clarify the causes of the error, a rebeling of the code responsible for the support of Ultima 4 & 6 was carried out.
The rebel passed as follows:
1. Removed ultima.lib (Static Library)
2. Left the entry point, deleted all other files associated with Ultima 4/6 from the project assembly
3. Collected ultima.lib, then collected scummvm.exe
4. Added files to the project and continued to collect until the error did not jump out.
I have done these steps first for Ultima 4, then - 6. In both cases, the reason was pointer-to-member array declaration.
Ultima 4 - https://github.com/scummvm/scummvm/blob/master/engines/ultima/ultima4/game/item.cpp#L49
Ultima 6 - https://github.com/scummvm/scummvm/blob/master/engines/ultima/nuvie/usecode/u6_object_types.h#L28
elf2e32 creates E32 aka EPOC32 aka Symbian exe and dlls from elf.
Analysis of the elf2e32 source code indicated the reason - when checking the created file, unaligned relocations were found. After modifying the source code, the elf2e32 was printed unaligned relocations. I redirect to file "readelf -a <name of elf>". I find several random Elf32_Rel r_offset from elf2e32 in readelf output. GCC 5.4.0 and 11.2.0 give same result.
Compiler options taken from Eclipse output and they are same for every source file: arm-none-symbianelf-gcc -O2 -fno-unit-at-a-time -fexceptions -Wall -Wno-unknown-pragmas -march=armv5t -mapcs-frame -mthumb-interwork -pipe -nostdinc -c -Wno-multichar -Wno-unused -Wno-format -fsigned-char -fno-asynchronous-unwind-tables -std=c++11 -v -pipe -Wno-multichar -Wno-reorder -Wno-unused -Wno-format -fsigned-char -Wno-psabi -marm -msoft-float -D__MARM_INTERWORK__ -DNDEBUG -D_UNICODE -D__GCCE__ -D__SYMBIAN32__ -D__S60_50__ -D__S60_3X__ -D__SERIES60_3X__ -D__GCCE__ -D__EPOC32__ -D__MARM__ -D__EABI__ -D__MARM_ARMV5__ -D__EXE__ -DENABLE_CGE -DENABLE_ULTIMA -DENABLE_ULTIMA6 -DS60 -DS60V3 -DSDL_BACKEND -DENABLE_VKEYBD -DUSE_TRANSLATION -DNONSTANDARD_PORT -DDISABLE_FANCY_THEMES -DUSE_A52 -DUSE_BINK -DUSE_FAAD -DUSE_FLAC -DUSE_FREETYPE2 -DUSE_JPEG -DUSE_MAD -DUSE_MPEG2 -DUSE_PNG -DUSE_THEORADEC

Ultima 4 & 6 support disabling allowed SCUMMVM. In the spring of this year, after some changes in the source code Ultima, the elf2e32 utility has begun to complete the work with the error "Line 427". To clarify the causes of the error, a rebeling of the code responsible for the support of Ultima 4 & 6 was carried out.

> Analysis of the elf2e32 source code indicated the reason - when checking the created file, unaligned relocations were found. After modifying the source code, the elf2e32 was printed unaligned relocations. I redirect to file "readelf -a <name of elf>". I find several random Elf32_Rel r_offset from elf2e32 in readelf output. GCC 5.4.0 and 11.2.0 give same result.

I can't tell from this what the issue might be. To stand any chance of
proceeding further, I think we're going to need a simple,
self-contained, testcase that can demonstrate the problem.
I don't think I've seen a question about SymbianOS support in over 5
years, now, possibly longer. Given that SymbianOS itself was
discontinued back around 2013 (8 years ago now), the GCC port has
declined to the point where I suspect it's likely to get deprecated
soon, due to lack of maintenance.

I need some time to reduce code size. This is big project.

There several configure problems but result is good. It just works. This is offtopic but can be continued in separate thread.

Such things are never off-topic :-)
Someone needs to do maintenance on the port. An important first step is
to regularly (and at least semi-frequently) post testresults. That also
shows everyone there is still some interest in the port, and importantly
it shows what the current state is.

I wrote in email all build issues later. I need to build GCC 11 again to gather info.
Libsupc++ tied to libstdc++ is major problem because it depends from libc. Therefore libsupc++ may(and probaly will) depend from libc. Symbian itself doesn't need libc. It's ordinal library in Symbian.

What do you mean "tied to"?

Libsupc++ has minimal dependencies on libc, and what it has is
optional/configurable.
Are you building with --disable-hosted-libstdcxx to get a freestanding
libsupc++ build?

I can't build libsupc++ without call "make something_command_for_libsupc" because got error because libstdc++ builds together with libsupc. I can't remember command's name. I build many releases from GCC 5.4.0 till 11.2.0. Errors always same.

Maybe if you report a bug we can help. If you can't even tell us what the
error is, nobody can help.

After modifying the source code, the elf2e32 was printed unaligned relocations. I redirect to file "readelf -a <name of elf>". I find several random Elf32_Rel r_offset from elf2e32 in readelf output. GCC 5.4.0 and 11.2.0 give same result.

I made very small testcase in main.cpp. Attachment contains Carbide С++

I've had a very quick look at this (I can only look at the compiler
output as I do not have any of the other symbian-related tools). The
only thing I can think of is that the problem is coming from the dwarf
debug information. Can you check whether the problem still occurs if
you add -g0 to the end of the list of compilation options (or remove all
the -g... options from the compilation command).
R.

Sorry for long response. You mail was moved to spam by mail provider.
Error remains.
I made this file OS-independent. It can be linked and compiled by GCC.
I compile and use object dump. Found unaligned entry. Is it error?
Output:
arm-none-symbianelf-gcc -c -marm main.cpp
arm-none-symbianelf-readelf -a main.o
Relocation section '.rel.rodata' at offset 0x9e0 contains 8 entries:

Sorry, I meant to also say that your source code is using two ways of
forcing packing: pragma pack and __attribute((packed)). If I remove
both of those, then the output becomes
Items::ITEMS:
.word .LC0
.word 0
.word .LC1
.word Items::isRuneInInventory(int)
.word 0
.word Items::putRuneInInventory(int)
.word 0
.word 0
.word 0
.word 64
.byte 0
.space 3
.word .LC2
.word 0
.word .LC3
.word Items::isRuneInInventory(int)
.word 0
.word Items::putRuneInInventory(int)
.word 0
.word 0
.word 0
.word 128
.byte 0
.space 3
.space 1408
and we can see that the data is all now fully aligned. Leaving either
one of the packed directives in place obviously leads to the object
containing unaligned pointers, which leads to the unaligned relocations.
AAELF (the ELF specification binding for Arm) states:
Except as indicated in Table 4-10, Static Data relocations with
non-standard size or processing all static data relocations have
size 4, alignment 1 and [...].
R_ARM_ABS32 is not listed in Table 4-10, so can have any alignment.
R.
