CXX on X86 : missing align_val_t??

[joukj]

Hi ,
I get the following when linking a c++ program compiled with /standard=gnu17 (which I realy need):

Code: Select all

link pdfdetach.obj,parseargs.obj,[-.poppler]libpoppler.olb/lib,	[]vms_link/opt
%ILINK-W-NUDFSYMS, 2 undefined symbols:
%ILINK-I-UDFSYM, 	_ZdlPvSt11align_val_t 
%ILINK-I-UDFSYM, 	_ZnwmSt11align_val_t 
%ILINK-W-USEUNDEF, undefined symbol _ZdlPvSt11align_val_t referenced
	section: .text._ZNSt3__117_DeallocateCaller9__do_callISt11align_val_tEEv
PvT_
	offset: %X0000000000000028
	module: PDFDETACH 
	file: $DSTM:[JOUKJ.public.poppler.poppler_2023-07-17.poppler.utils]PDFDE
TACH.OBJ;2 
%ILINK-W-USEUNDEF, undefined symbol _ZnwmSt11align_val_t referenced
	section: .text._ZNSt3__117__libcpp_allocateEmm
	offset: %X000000000000004A
	module: PDFDETACH 
	file: $DSTM:[JOUKJ.public.poppler.poppler_2023-07-17.poppler.utils]PDFDE
TACH.OBJ;2 

I can find the 2 missing ones in the compiler executable in sys$system, but nothing in sys$library & sys$share.
Is something missing?

Jouk
I use :
clang version 10.0.1 (git@bitbucket.org:vms_software/llvm-10.0.1.git d469fd71c59
f33c7d998debe420a69abb31f1f57)
Build date: 06-16-2023
Target: x86_64-OpenVMS
Thread model: posix
InstalledDir: RUMBA$DKA100:[SYS0.SYSCOMMON.][SYSEXE]
on OpenVMS x86_64 V9.2-1

I haven't seen that. I would need to see a reproducer.

What in C++17 do you need? We have several missing C++17 libraries and classes and I've been saying C++14 only.

I'm trying to compile the package poppler (extracted from their git repository afew days ago).

with /stan=cxx14 I get:

Code: Select all

Just released a new kit that should include align_val_t.

[jreagan]

The errors with /STANDARD=CXX14 are because ::optional is new to C++17. The errors with CXX14 seem expected (perhaps not very helpful to realize the bad CXX14 vs CXX17 setting)

[joukj]

confirm: this is fixed in the latest CXX compiler
